Answer:
The coefficients are 6, 1, 3
Explanation:
HNCO →C3N3(NH2)3 + CO2
From the above equation, there are a total of 6 atoms of nitrogen on the right side and 1atom on the left. It can be balance by putting 6 in front of HNCO as shown below:
6HNCO → C3N3(NH2)3 + CO2
Now there are 6 atoms of carbon on the left side and 4 atoms on the right side. It can be balance by putting 3 in front of CO2 as shown below:
6HNCO → C3N3(NH2)3 + 3CO2
Now the equation is balanced as the numbers of atoms of the different elements on both sides of the equation are the same.
The coefficients are 6, 1, 3
MgSO4, CO2, AlCl3 are the answer
Benzene
- Benzene has low density than the water itself of about 0.9 g/cm³
Low denisty object than the water usually <u>floats on the water</u>.
Another example: orange peel which floats on water has density of about 0.84 g/cm³
Answer:
Honey
Explanation:
It’s honey because the item that was dropped in it is almost at the top and that means there is something sticky or force there holding it back!
CH3COOCH3
We have 2 atoms of oxygen - 2*M(O)=2*16.0=32.0 g/mol
Molar mass (CH3COOCH3)= 3*M(C)+2*M(O)+6*M(H)=3*12.0+2*16.0+6*1.0=
= 74.0 g/mol
% oxygen=(32.0 g/mol)/( 74.0 g/mol) *100% ≈ 43.2%
