Answer:
A weak acid
Explanation:
Im not sure if its right. But lets see someone else do it.
We have to calculate formula mass of N₂O.
The answer is: 44
Relative formula mass is the sum of relative atomic mass of constituent atoms in a formula unit of any compound. Relative formula mass is represented as same symbol of relative molecular mass.
To calculate relative formula mass we need to know number of each atom in the formula and then adding atomic masses of all the atoms.
In N₂O, number of N-atom present is equal to 2 and number of O-atom is equal to 1.
Atomic mass of N-atom is 14 and atomic mass of O-atom is 16.
So, formula mass of N₂O is (2 X 14)+16 = 44.
The correct answer among the choices given is option D. Benzene is the simplest aromatic compound. It is the basic unit or part of an aromatic compound. It has a configuration of six carbon atoms. Aromatic compounds can be monocyclic consisting of only one benzene or polycylclic consisting of many benzene rings.
D.
the total mass of the products will be equal to the original mass of the reactants.
Explanation:
Ca + 2H₂O → Ca(OH)₂ + H₂
From this chemical reaction, one can conclude that when the reaction reaches completion, the total mass of the products will be equal to the original mass of the reactants. This is in compliance with the law of conservation of mass.
- The law of conservation of mass states that matter is the mass of products in a chemical reaction is the same as mass of the reactants.
- This implies that the mass of the products in a given reaction is the same as that of the reactants.
- No mass is lost in the process of a chemical change.

Answer:
FALSE
Explanation:
Br is <em>bromine</em> with atomic number 35, mass number of 79.904 and belongs to the group 7 elements known as the halogens.
Ga is <em>gallium</em> with atomic number 31, mass number of 69.72 and belongs to the alkaline earth metal i.e the group 3 elements.
From the above and in terms of their mass number, it is evident that Br is the larger element compared to Ga which is lesser than Br. Hence the statement is FALSE
