tester [92]

Answer:

1,2,3

Explanation:

Heat gain implies that heat is absorbed by the system in order to make the stated phase transition possible.

Before a liquid changes to gas, intermolecular forces in the liquid are broken by energy supplied as heat.

Also, transition from solid to liquid requires energy to break intermolecular bonds.

Finally, sublimation requires input of energy in the form of heat.

Len [333]

Answer:

12.044 ×10²³ molecules of HCl

Explanation:

Given data:

Number of moles of MgO = 1 mol

Number of molecules of HCl react = ?

Solution:

Chemical equation:

MgO + 2HCl       →     MgCl₂  + H₂O

with 1 mole of MgO 2 moles of HCl are react.

Number of molecules of HCl react:

1 mole contain 6.022×10²³ molecules

2 mol × 6.022×10²³ molecules / 1 mol

12.044 ×10²³ molecules
