When mixing substances, in order to find the final temperature after mixing, it is important to remember that the energy released should be equal to the energy absorbed by the system. We calculate as follows:
Q1 = Q2
(mCΔT)1 = (mCΔT)2
100 ( 90 - T ) = 50 ( T - 10 )
T = 63.33 °C
Answer:
C₃H₆O₃
Explanation:
Data:
EF = CH₂O
MM = 90. g/mol
Calculations:
EF Mass = (12.01 + 2.016 + 16.00) u = 30.03 u
The molecular formula is an integral multiple of the empirical formula.
MF = (EF)ₙ
![n = \dfrac{\text{MF Mass}}{\text{EF Mass }} = \dfrac{\text{90. u}}{\text{30.03 u}} = 3.00 \approx 3](https://tex.z-dn.net/?f=n%20%3D%20%5Cdfrac%7B%5Ctext%7BMF%20Mass%7D%7D%7B%5Ctext%7BEF%20Mass%20%7D%7D%20%3D%20%5Cdfrac%7B%5Ctext%7B90.%20u%7D%7D%7B%5Ctext%7B30.03%20u%7D%7D%20%3D%203.00%20%20%5Capprox%203)
MF = (CH₂O)₃ = C₃H₆O₃
Answer:
you picked the right one the net worth of force would be 10
Explanation:
how cuz you got 1 team with 6 force then aother 1 with 4 add em up u get 10
