What mass of oxygen is needed to produce 13 g of this product? 31g + x = 71g 71g 31g = 40g oxygen This means that in 71 g of the product there are 40 g of oxygen. 40/71 * 13 g = 7. 32 g 44. Gasoline can be approximated by the formula C8H18. An environmental advocate claims that burning 1 gallon (about 7 lb) of gasoline produces about 19 lb of carbon dioxide, a greenhouse gas. Explain this apparent contradiction of the law of conservation of mass. Because there is no oxygen added to the 7lbs of C8H18 and therefore, you cannot create oxygen without having oxygen because mass and matter is not created or destroyed. 6. Two experiments were performed in which sulfur was burned completely in pure oxygen gas, producing sulfur dioxide and leaving some unreacted oxygen. In the first experiment, 0. 312 g of sulfur produced 0. 623 g of sulfur dioxide. In the second experiment, 1. 305 g of sulfur was burned. What mass of sulfur dioxide was produced? 0.

What is the mass in u of each atom in Question 5? Atom A- 21 amu Atom B- 21 amu Atom C- 22 amu Atom D- 20 amu 7. Compare Dalton’s model of the atom with the nuclear model of the atom. Dalton atomic model is the simplest model. Atoms only described as a very small ball but massive. This model is still not familiar with the charge within the atom. The nuclear model the atoms are not massive but hollow objects. Electrons are not scattered evenly in the nucleus but are at great distances from the nucleus. Rutherfords theory also states that the electrons are not silent but orbit around the nucleus. 9.

For this intent, 60 kids, thirty each from Montessori and Kindergarten under the age group of 7-8 old ages will take portion in this survey. General Mental Ability Test for Children ( GMATC ) will be used as an instrument for the informations aggregation. Introduction This research will analyze the two methods of instruction i.e. Montessori and Kindergarten and their impact on the development of general mental ability of the kids aged 7-8 old ages. The hypothesis of the research is kids from Montessori have higher General Mental Ability than kids from Kindergarten. The Variables which will be studied are Mode of Education i.e. Montessori A ; Kindergarten ( Independent Variable ) and General Mental Ability ( Dependent Variable ) . Operational definition Montessori instruction refers to the instruction imparted by instructors who have undergone a mandetory one twelvemonth Montessori preparation class. They are trained in such a manner that they aim to do the kid understand the construct instead than merely memorise stuff, unlike in Kindergarten, where they largely focus on rote method and ignore explicating the nucleus construct. General Mental Ability refers to five mental abilities-analogy, categorization, figure series, concluding jobs, and absurdnesss. It is an ability to larn things by understanding the construct. Education plays an of import function in the development of a state and the advancement of a state. It is a method by which we get accomplishments, cognition and attitude ( Importance of Education, n.d. , p. 9 ) . There have been assorted methods of instruction that evolved over the old ages. One such method is Montessori instruction and a survey conducted by Angeline Lillard and Nicole Else-Quest ( 2006 ) revealed that Montessori instruction has important advantages when compared to non-montessori school. However the benefits of Montessori instruction are non realised by many people in India and are incognizant of its advantages. Therefore this survey aims to place the best signifier of instruction and its impact on the rational development of the kids. THEORETICAL BASE The General Mental Ability of a individual depends upon the quality of preparation that one receives during childhood. During childhood, kids have immense potency to develop their mental ability as they can quickly hold on and larn things. Tomonari, Dana, Feiler and Rachelle ( 2003 ) references that the clip from 0-8 old ages is a critical period in the development of many foundational accomplishments in all countries of development. Therefore, it is important that kids receive good instruction during this period so as to develop their mental ability. Kamala dev ( 2010 ) believes that diverseness in the instruction methodological analysiss will do a immense difference to the attack the kid develops toward instruction. FaithAllen ( n.d. ) states that, Montessori Method of instruction has been around for a century and has been proven to be a really successful signifier of instruction. Harmonizing to North American Montessori Teachers Association, Montessori instruction emphasizes larning through all five senses, non merely through hearing, watching, or reading. Children in Montessori categories learn at their ain, single gait and harmonizing to their ain pick of activities from 100s of possibilities. Learning is an exciting procedure of find, taking to concentration, motive, self-discipline, and a love of larning. Montessori classes topographic point kids in three-year age groups ( 3-6, 6-9, 9-12, and so on ) , organizing communities in which the older kids spontaneously portion their cognition with the younger 1s. Montessori represents an wholly different attack to instruction. On the other manus Kindergarten is the most common option selected by many people since several old ages for their kids and the most adept method is frequently referred to as the traditional system. This system is non the most effectual in footings of ensuing in existent acquisition and has many disadvantages that are really counter productive to existent acquisition. The traditional educational system focuses wholly on rational and ignores experiential acquisition, teaches pupils merely how to win on standardized trial.This manner of acquisition is intended to let pupils to derive single significance to the capable affair ( Kevin James Bondelli, n.d ) . Methodology The entire sample population for this survey is 60 kids in the age group of 7-8 and they will be selected by the agencies of purposive sampling. 30 kids will be indiscriminately selected from Montessori and likewise 30 kids will be indiscriminately selected from traditional school. General Mental Ability Test for Children ( GMATC ) for 7-11 old ages by R. P. Srivastava A ; Kiran Saxena will be used as an instrument for the informations aggregation. It is both verbal and non-verbal and measures five mental abilities-analogy, categorization, figure series, concluding jobs, and absurdnesss and the clip bound will be 30 proceedingss. In order to do the kids take part, consent signifier will be given to the principal of each school for their permission. Each participant will be provided with the test.Thereafter instructions will be given to them and will be assisted as and when required. The experimental design of the subject is simple random assignment as it is convenient to utilize, ha s a simple design, involves less attempts and besides other variables are controlled. The trying method will be Purposive sampling ( we sample with a intent in head ) of Non-probability sampling ( does non affect random choice ) as merely those kids will be tested who are peculiarly from Montessori and kindergarten for turn outing the subject. RELEVENCE When parents decide upon an educational arrangement for their kid, it is of import to look into the best suited educational option for their kid. It is of import to acknowledge the differences in the assorted learning methods and their impacts on kids s mental ability. The mental ability of a individual depends upon the quality of preparation that one receives during childhood. If the proper instruction is non imparted to the kids in their right age so the developmental growing will be affected. They could be less competent when compared to kids having quality instruction in their early childhood. Harmonizing to International Save the Children Alliance ( 2006 ) , Education plays a critical function in fostering future coevalss. While enabling personal growing, it besides contributes to economic and societal development. Kindergarten Education has been followed by many people as a traditional path since several decennaries. In India there is a deficiency of consciousness on the import ant benefits of Montessori Education when compared to Kindergarten Education. Therefore, this research will be instrumental in distributing the consciousness of Montessori Education in India and thereby developing general mental ability of future coevals. Evaluation One of the challenges that might meet during the research will be to pull off the kids. However this can be overcome by seeking their category instructor s support as kids tend to listen to them. Another challenge could be kids copying the replies of the trial from their equals, to avoid this, kids will be divided into little groups and will be made to sit far from each other. Another job which may happen is that some kids would non wish to take up the trial for which the support of their instructors could be taken or can utilize the method of support. Decision The chief purpose of the survey is to happen out the difference between Montessori and Kindergarten manner of instruction and distributing the positive benefits of Montessori instruction and thereby turn outing the hypothesis i.e. kids from Montessori have higher General Mental Ability than kids from Kindergarten.
