Answer:
A. -205.7 kJ
Step-by-step explanation:
The overall enthalpy of reaction be calculated when the intermediate steps are present
formed in a multi-step process.
Answer:
I may not be correct on this but I believe this is either Linear Function or other
Step-by-step explanation:
I was doing a bit of research and Linear Function or other fit best for this graph
7m - 3m + 5 = 45
4m + 5 = 45
45-5 = 40
4m = 40
40/4
m = 10 minutes
Answer:
I believe it's C
Step-by-step explanation:
Answer:
x = 26.5
Step-by-step explanation:
Step 1: Write equation
(t + 10.5) + 2t + 90 = 180
Step 2: Solve for <em>t</em>
<u>Combine like terms:</u> 3t + 100.5 = 180
<u>Subtract 100.5 on both sides:</u> 3t = 79.5
<u>Divide both sides by 3:</u> t = 26.5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
<u>Substitute:</u> (26.5 + 10.5) + 2(26.5) + 90 = 180
<u>Parenthesis:</u> 37 + 56 + 90 = 180
<u>Add:</u> 180 = 180
∴ x = 26.5
