Seek the chemical equation of alcohol ignition to produce carbon dioxide and water!

The chemical equation for the formation of carbon dioxide and water by ignition of alcohol is as follows:
CH3CH2OH + 3O2 = = ignition = = 2co2 + 3H2O

What's the chemical equation of ethanol burning in oxygen to produce carbon dioxide and water
A small amount of ethanol with a mass of 23g and a certain amount of oxygen with a mass of 40g are burned to produce 22G of carbon dioxide, 27g of water vapor and 14g of an unknown substance

2C2H0OH+5O2=2CO2+6H2O+2CO

How to convert 1000 kg / M & sup3; equal to kg / DM & sup3; equal to g / cm & sup3

It's all 1

The unit of each physical quantity, especially the unit of period, is s or H

When choosing different units, there will be different formulas
If we infer the two formulas GMM / R ^ 2 = m (2 π / T) ^ 2R. M = (4 / 3) (ρ π R ^ 3), the corresponding units are all international units
That is, the unit of length is m, the unit of time is s, and the unit of mass is kg

How to convert g / cm ^ 3 to 1000kg / m ^ 3
I only know how to convert 1000kg / m ^ 3 into g / cm ^ 3, but I don't know how to convert it. I'm a bit of a dead brain, don't mind. I need to know the specific process

1g=1/1000kg
1cm^3=1/100^3m^3
So 1g / cm ^ 3 = (1 / 1000) / (1 / 100 ^ 3) kg / m ^ 3
That is 1000 kg / m ^ 3
