there are 6 total Hydrogen atoms in Dimethylnitrosamine
Let (CH2O)n be molecular formula,
(12+1+1+16)n=90.08
30n=90.08
n=3
molecular formula: (CH2O) 3= C3H6O3
Answer:
0.0152
0.0000000778
Explanation:
You just need to more the decimal as many times as the exponent to the to the left if it is negativa and to the right if it is positive.
We first have to find Q calorimeter
Q calorimeter = C (delta T)
C= heat capacity in J/oC, not small c ( specific heat capacity)
delta T= change in T (oC) = final T - initial T
Q calorimeter = 10.4 J/oC (30 oC - 25 oC)
Q calorimeter = 52 J
Remember,
Q calorimeter = - Q surrounding
The (-) negative sign stands for heat being released.
So ,
Q surrounding = - 52 J
In other words, the iron releases 52 J .
The calorimeter absorbs the entire 52 J and heat rose from 25 - 30 oC.
Answer: 52 J
Answer:
Your answer is B, Electrochemistry!
Explanation:
This is the part of chemistry that studies the chemical process in which electrons flow. This flow is called electricity. Electricity is generated by the flow of electrons, from one element to another element. This reaction is called oxidation reduction.
