Which of the following is true for balancing equations?

Chemistry
1 answer:
algol [13]3 years ago
5 0

Answer:

A.

Explanation:

An equation with the equal amount and proportion of atoms of each element on both sides of the reaction is commonly referred to as a balanced chemical equation.

The law of conservation of matter asserts that no observable and empirical change in the amount of matter occurs within a conventional chemical process. As a result, each element in the product would have the same equal amount or numbers of atoms as the reactants.

How many moles are in 14.35 x 1022 molecules of H3PO4?
Irina18 [472]

Answer:

0.24mole

Explanation:

Given parameters:

Number of molecules  = 14.35 x 10²² molecules;

       Unknown = number of moles of H₃PO₄

 A mole of a substance is the quantity of matter that contains the avogadro's number of particles.

 This number is given as 6.02 x 10²³ particles. The particles can be atoms, molecules, protons, electrons e.t.c

          6.02 x 10²³ molecules is contained in 1 mole of any substance

          14.35 x 10²² molecules will contain:  \frac{1.435 x 10^{23} }{6.02 x 10^{23} }   = 0.24mole
