Answer:

Explanation:

A, B and C are incorrect since the greater the pH value, the more alkaline a solution is, and the pH of water is 7.

In the statement D, the pH of NaOH solution is 13 usually, so the given solution is less alkaline than NaOH solution, and I think of the same concentration is somewhat unnecessary.

As the temperature of a gas increases, explain what happens to its density and why.

Ghella [55]

Answer:

When a gas is heated, the molecules move faster, bump into each other, and spread apart. Because the molecules are spread apart, they take up more space. They are less dense.

Calculate the mass of magnesium carbonate ( MgCO3), in grams, required to produce 110.0 g of carbon dioxide using the following

bearhunter [10]

Answer:

$210.7~g~MgCO_3$

Explanation:

We have to start with the reaction:

$MgCO_3~->~MgO~+~CO_2$

We have the same amount of atoms on both sides, so, we can continue. The next step is to find the number of moles that we have in the 110.0 g of carbon dioxide, to this, we have to know the atomic mass of each atom:

C: 12 g/mol

O: 16 g/mol

Mg: 23.3 g/mol

If we take into account the number of atoms in the formula, we can calculate the molar mass of carbon dioxide:

$(12*1)+(16*2)=44~g/mol$
