Answer:
3
Step-by-step explanation:
Solve for x:
-6 + x = -3
Add 6 to both sides of the equal sign so -6 cancels out on the left side
+6 - 6 + x = -3 + 6
x = - 3 + 6
x = 3
I hope this helps! Good luck with your schoolwork :)
Answer:
0.65
Step-by-step explanation:
Find a common denominator, but whatever you multiply it by, you must take the same number and multiply the numerator as well. I hope that helps- Good luck!
Answer:
Step-by-step explanation:
Remark
The formula for this is
Heat = m * c * Δt
Givens
Heat = unknown
m = 200 grams
c = 4.184 Joules / grams oC
Δt = the change in temperature = 35.7 - 22.3 = 13.4
Solution
Heat = 200 * 4.184 * 13.4
Heat = 11213 Joules
Heat = 11.2 Kj
It's hard to get the correct number of sig digs because the 200 is not qualified in any way.
Part 2.
This can really puzzle you until you know that heat given up = the heat taken on. The heat taken on was 11.2 Kj. The Butane lighter must have given that heat on.
Heat of Combustion = Heat Given Up / Number grams burned.
Heat of Combustion = 11.2 Kj / 0.23 grams
Heat of Combustion = 48.8 Kj / gram
Angles 1 and 3, angles 2 and 4, angles 5 and 7, and angles 6 and 8. They are also congruent, because vertical angles are congruent.
