Answer:

<h3>The answer is 0.49 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 2.34 g

density = 4.78 g/mL

We have

volume =  \frac{2.34}{4.78}  \\  = 0.4895397...

We have the final answer as

<h3>0.49 mL</h3>

Hope this helps you

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)

?

Sol:-

Since the pressure is constant and the question is asking about temperature and volume, i.e,

V
