What are the coefficients that would balance the chemical equation below?

Chemistry
1 answer:
Ludmilka [50]3 years ago
7 0

The coefficients :  3, 2, 1,3

<h3>Further explanation</h3>

Given

Reaction

Mg + H3PO4 -> Mg3(PO4)2 + H2

Required

The coefficients

Solution

Steps to balance reactions:

1. Give a coefficient(The most complex compound is assigned a coefficient of 1)

aMg + bH₃PO₄ ⇒ Mg₃(PO₄)₂ + cH₂

2. Make an equation

Mg, left = a, right = 3 ⇒a=3

P, left = b, right = 2⇒b=2

H, left = 3b, right = 2c⇒3b=2c⇒3.2=2c⇒2c=6⇒c=3

The equation becomes :

<em>3Mg + 2H₃PO₄ ⇒ Mg₃(PO₄)₂ + 3H₂</em>

Which pair of substances would most likely result in the production of a gas when reacting with an acid?
vovangra [49]

Answer: metal and carbonate

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions (OH^-) when dissolved in water and an acid is defined as a substance which donates hydrogen ions (H^+) in water.

An acid is represented as :

HX\rightarrow H^++X^-

1. When metal is treated with an acid such as HCl, if the metal is more reactive than hydrogen displaces hydrogen from its salt solution and thus produce zinc chloride and hydrogen gas.

M+xHCl(aq)\rightarrow MCl_x(aq)+xH_2(g)

2. When carbonates are treated with acid, double displacement takes place ad carbon dioxide is released as a gas.

MCO_3(aq)+xHCl(aq)\rightarrow MCl_x(aq)+xH_2O(l)+CO_2(g)

How many liters of carbon dioxide gas are there in 4 moles of CO2 at STP?
Ad libitum [116K]

Answer:

<u>89.6 L</u>

Explanation:

In normal conditions,

<u><em>For every </em></u><u><em>1 mole</em></u><u><em> of carbon dioxide at STP, it occupies </em></u><u><em>22.4 L</em></u><u><em> of volume.</em></u>

<u><em /></u>

============================================================

Solving :

⇒ 1 mole : 22.4 L

⇒ 1 × 4 : 22.4 × 4

⇒ 4 moles : <u>89.6 L</u>
