An endothermic solution process is described by which of the following?

Temka [501]

Answer:

a. ΔΗ > 0, solution feels cold

Explanation:

Hello,

In this case, endothermic process are those in which we can find that the products have more energy than the reactants, therefore energy is absorbed, for which the following equation:

$\Delta H=\Delta H_{products}-\Delta H_{reactants}$

Must be greater than 0 (positive) thereby, for a solution process we find that the solution feels cold, in such a way, answer is a. ΔΗ > 0, solution feels cold.

Regards.

Answer:

Mass = 8 g

Explanation:

Given data:

Mass of MgO formed = 20 g

Mass of oxygen needed = ?

Solution:

Chemical equation:

2Mg + O₂ → 2MgO

Number of moles of MgO:

Number of moles = mass/molar mass

Number of moles = 20 g/ 40 g/mol

Number of moles = 0.5 mol

Now we will compare the moles of MgO and O₂ from balance chemical equation:

MgO : O₂

2 : 1

0.5 : 1/2×0.5 = 0.25 mol

Mass of oxygen required:

Mass = number of moles × molar mass

Molar mass of O₂ is 32 g/mol

Mass = 0.25 mol × 32 g/mol

Mass = 8 g
