standard heat of formation

The heat content of a substance is called its (1). The change
in this quantity that occurs during a chemical reaction is called
the (2) __, AH. If the chemical change is the production of a
compound from its elements, this quantity is called the
(3)
At 25°C and 1 atmosphere of pressure, it is called the
(4)
The sign of the quantity AH is positive in the case of an)
(5)
It is negative in the case of an)
(6)
When a reaction can be expressed as the algebraic sum of two
or more other reactions, its heat of reaction is equal to the alge-
braic sum of the heats of these other reactions. This relationship
is called (7)
A measure of the randomness of a system is its (8) If, in
any reaction, the change in this quantity is multiplied by the
19)
and subtracted from AH for the reaction, the result is
called the (10) of the reaction. If the reaction is the production
of a compound from its elements, the above result is called the
(11) of the compound. This relationship is expressed in the
(12)

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent. true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight. a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
