Answer:
62.86
Step-by-step explanation:
Add the cost of things without sales tax:
32.5+ (13×2)=58.5
Convert percent to decimal:
8/100=0.08
Multiply cost without sales tax by sales tax to get the amount added to the cost:
0.08×58.2=4.656
Add cost and sales tax amount to get total payment:
4.656+58.5=62.856
Round the total payment to the nearest hundredth place:
62.86
Answer:
A
Step-by-step explanation:
Entropy is the measure of how disordered a system is. The higher the entropy, the more disordered. Whenever we go from a solid to liquid to gas, that's considered an increase in entropy because the molecules are moving faster and in more random directions. Eliminate B and D
Meanwhile, notice that we see the +34.89 kJ on the left side of the equation / the reactant side of the equation. This means that the reaction is endothermic because there is an input of energy. If the +34.89 kJ was on the right side / the product side, then it would be exothermic.
Thus, the answer is A.
Hope this helps!
