Answer:
A property that changes if the amount of substance changes
Explanation:
An extensive property is a property that depends on the amount of matter in a sample.
An extensive property changes if the amount of substance changes. For instance, mass and volume are extensive properties as they would vary depending on the amount of substance.
An extensive property is a property that changes if the amount of substance changes. For example, mass and volume are extensive properties. If you have two separate samples of a substance, each with a different amount, their mass and volume would be different. On the other hand, the melting point or boiling point of the substance, which are examples of intensive properties, would not change regardless of the amount of substance.

1. _____. the phase change of a substance from the solid state directly to the gaseous state; for example, dry ice, moth balls, or solid air freshener
2. _____. a form of energy transferred (by way of conduction, convection, or radiation) by virtue of a difference in temperature; heat is energy in transit; heat is energy flow, measured in energy units
3. _____. matter with definite volume and definite shape
4. _____. theory in physics based on the fact that particles of matter are in vigorous motion and that the temperature of a substance increases with an increase in either the average kinetic energy of the particles or the average potential energy of separation of the particles, or in both, when heat is added
5. _____. a measure of how hot or cold something is; a measure of the average kinetic energy of the particles of a substance
6. _____. matter with no definite volume or shape
7. _____. the process by which a gas changes phase directly to a solid; for example, the formation of frost
8. _____. a gaslike state of matter consisting of positively charged ions, free electrons, and neutral particles; found in stars, the sun, solar wind, lightning, and fire; unlike gases, plasmas are good conductors of electrical currents
9. _____. net absorption of energy
10. _____. the transfer of heat through matter by way of the collision of molecules
11. _____. heat; energy transferred due to temperature differential that becomes associated with potential energy and kinetic energy on a molecular level
12. _____. the process by which water vapor changes from gas to liquid
13. _____. in a closed system in changing from one form to another, matter and energy cannot be created or destroyed; in this sense, conservation means that the physical quantity of matter and energy is entirely preserved during transformations and reactions
14. _____. physical form of matter, such as solid, liquid, and gas; a distinct state of matter in a system; matter that is identical in chemical composition and physical state, and is separated from other material by the phase boundary; for example, the reaction occurs in the liquid phase of the system
15. _____. the process by which water changes to water vapor
16. _____. net release of energy
17. _____. SI-derived unit to measure energy, work, and quantity of heat; for work, a joule is the amount of work done by a force of 1 N acting through 1 m; also newton-meter
18. _____. matter with definite volume but no definite shape.

Consider looking up those definitions in a dictionary or in the appendix of your textbook.
Answer is in the Word document.
Ba(OH)2 (aq) + H2SO4(aq) → BaSO4(s) + H2O(l)
BaSO4(s) + 2 H2O(l) → Ba(OH)2 (aq) + H2SO4(aq)
Ba(OH)2 (aq) + H2SO4(aq) → BaSO4(s) + 2 H2O(l)
Answer:
Ba(OH)2 (aq) + H2SO4(aq) → BaSO4(s) + 2 H2O(l)
That's the right one.
Explanation:
You should see that this equation is balanced, not as
Ba(OH)2 (aq) + H2SO4(aq) → BaSO4(s) + H2O(l)
(on reactive we have 4 H, on products, we have only 2)
Ba(OH)2 (aq) + H2SO4(aq) → H2Ba(s) + SO4(OH)2(l)
(this is impossible, it's a nonsense)
BaSO4(s) + 2 H2O(l) → Ba(OH)2 (aq) + H2SO4(aq)
(it is the same with the right one but is the other way around. The statement says, reaction of Ba(OH)2 with H2SO4, not BaSO4 with water. Also, it is not a chemical balance.
The reaction forms 0.112 mol H_2.
We have the masses of two reactants, so this is a limiting reactant problem.
We know that we will need a balanced equation with masses, moles, and molar masses of the compounds involved.
Step 1. Gather all the information in one place with molar masses above the formulas and everything else below them.
M_r: __89.64 ___18.02 ___________2.016
______SrH_2 + 2H_2O → Sr(OH)_2 + 2H_2
Mass/g: 5.00 ___5.47
Step 2. Calculate the moles of each reactant
Moles of SrH_2 = 5.00 g SrH_2 × (1 mol SrH_2 /89.64 g SrH_2)
= 0.055 77 mol SrH_2
Moles of H_2O = 5.47 g H_2O × (1 mol H_2O/18.02 g H_2O)
= 0.3036 mol H_2O
Step 3. Identify the limiting reactant
Calculate the moles of H_2 we can obtain from each reactant.
From SrH_2: Moles of H_2 = 0.055 77 mol SrH_2 × (2 mol H_2 /1 mol SrH_2) = 0.112 mol H_2
From H_2O: Moles of H_2 = 0.3036 mol H_2O × (2 mol H_2/2 mol H_2O)
= 0.3036 mol H_2
SrH_2 is the limiting reactant because it gives the smaller amount of H_2.
It produces 0.112 mol H_2.
