Answer: A chemical equation can be defined as balanced chemical equation if the number of atoms and the total charge is same on both sides of the reaction i.e reactants and products have same number of atoms.
Whereas, imbalanced reaction does not have same number of atoms and charge on reactants and products.
A. 2CO + 2NO → 2CO2 + N2
is a balanced equation as the number of carbon, oxygen, and nitrogen atoms are same on both sides.
B. 6CO2 + 6H2O → C6H12O6 + O2
is an imbalanced equation as oxygen atoms are not balanced here.
C. H2CO3 → H2O + CO2 is a balanced equation as same number of hydrogen, carbon, and oxygen are present on both sides.
D. 2Cu + O2 → CuO is an imbalanced equation as both copper and oxygen are imbalanced here.
Okay so molar mass is given, no. of moles is given and we have to calculate the weight or mass of the compound in gram. the formula we will use here is= n=W/M where n is no. of moles ,w is weight in gram which we have to find and M is molar mass or formula weight which is given. so W=n x M use this formula you'll get the answer
The difference between the Thompson's plum pudding model and the Rutherford atom model is the location of the electrons (option a).
Explanation:
While Thompson compared his atom to a plum pudding, where the electrons floated freely in the pudding, Rutherford established the arrangement of the electrons in orbitals, which were found around the atomic nucleus like the planets around the sun.
Rutherford's findings also established the existence of a small, positively charged nucleus.
<em>Thompson and Rutherford models did not differentiate between the charges of electrons and protons
, overall charges or overall size of the atom.</em>
