Answer:

The correct statements are :

1. The enthalpy of the reaction is -184.6 kJ, and the reaction is exothermic.

2. The enthalpy of the reaction is 184.6 kJ and the reaction is endothermic.

Step-by-step explanation:

Enthalpy of reaction is amount of heat absorbed or released during the reaction.

If energy is required, enthalpy of reaction is positive and if energy is released the enthalpy of reaction is negative.

Exothermic reaction: The chemical change is accompanied by the release of heat energy

Endothermic reaction: The chemical change is accompanied by the absorption of heat energy.

So, from the above definitions, it is clear that the enthalpy of reaction of a exothermic reaction is negative and that of a endothermic reaction is positive.

Solve the literal equation for the indicated variable. Show your work.<br><br> P=2(l+w) for l.
Norma-Jean [14]

Answer:

l = P/2  -w

Step-by-step explanation:

P=2(l+w)

Divide each side by 2

P/2 = 2(l+w)/2

P/2 = l+w

Subtract w from each side

P/2 -w = l+w-w

P/2 -w =l

Marisol rode her bicycle each day for five days. estimate how far she biked in all. round each number to the nearest whole numbe
o-na [289]

Marisol biked a total of 71 miles. On the other hand, she biked about 10 more miles on Wednesday than on Thursday.

<h3>How to round numbers?</h3>

The general rule is to move the decimal number to its nearest tenth. For example, 5.6 should be rounded as 6 but 5.1 should be rounded as 5.

Now, let's round the distance covered by Marisol each day:

  • Monday: 12.3 = 12
  • Tuesday: 14.1 = 14
  • Wednesday: 17.7= 18
  • Thursday: 11.8 = 12
  • Friday: 15.2 = 15

<h3>What distance did Marisol covered?</h3>

To know this just add the distance every day:

  • 12 + 14 +18 + 12 + 15 = 71 miles

<h3>How much more did she bike on Wednesday than on Thursday?</h3>

Distance covered on Wednesday - distance covered on Thursday

  • 18 - 12 = 6 miles

Note: This question is incomplete; here is the missing information:

  • Monday 12.3
  • Tuesday 14.1
  • Wednesday 17.7
  • Thursday 11.8
  • Friday 15.2
