Answer:
No
Explanation:
The chemical reaction between magnesium metal and hydrochloric acid solution is not an acid - base reaction.
An acid - base reaction involves an acid and base to produce salt and water.
- This reaction is called a neutralization reaction.
- An acid is a substance that produces excess hydroxonium ions in solutions.
- A base produces excess hydroxyl ions in solution.
- When acids and base combines, the main product is a salt in water solution.
Answer:
The answer is
<h2>11.73 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass of object = 30.5 g
Density = 2.6 g/cm³
The volume is

We have the final answer as
<h3>11.73 mL</h3>

Answer: The partial pressure of
is 1.86 atm
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
The given balanced equilibrium reaction is,

Pressure at eqm. 0.973 atm 0.548atm x atm
The expression for equilibrium constant for this reaction will be,

Now put all the given values in this expression, we get :

By solving the term 'x', we get :
x = 1.86 atm
Thus, the partial pressure of
is 1.86 atm
