The sum of all coefficients = 7
<h3>Further explanation</h3>
Given
The word equation
Required
The sum of all coefficients
Solution
The chemical equation can be expressed in terms of:
- word equation
- skeleton equation
- balanced equation
Convert the word equation into a chemical equation(skeleton) :
Ga + Cl₂ → GaCl₃
Balanced equation
2Ga + 3Cl₂ → 2GaCl₃
The sum of all coefficients :
= 2+3+2
= 7
The appropriate response is water. This reversible reaction can be broken into two responses. These two responses are happening all the while, which implies that the reactants are responding to yield the items, as the items are responding to deliver the reactants. Crashes of the responding atoms cause substance responses in a shut framework.
Answer:
If pressure increases, then volume decreases and vice versa, when temperature is held constant.” When pressure increases, the same number of molecules, or matter, are being forced closer together to occupy a shrinking space, their volume decreasing while their density correspondingly increases.
Explanation:
Answer:
Magnesium bromide, MgBr2, and water, H2O.
Explanation:
Hello!
In this case, since HBr is an acid and Mg(OH)2 is a base, an acid-base reaction is undergone, by which a salt and water are produced as neutralization products:
However, it need to be balanced since two bromine atoms are produced, therefore we write:
Thus, the products are magnesium bromide, MgBr2, and water, H2O.
Best regards!
