Answer:
1 mole CO2 = 44g i.e.by the complete combustion of 12g of carbon, 44g of CO2 is produced.
Explanation:
I'm not sure about 2 but in 3 it would float
Molar mass of CH2NH2COOH - 75
Given mass of CH2NH2COOH - 30
Moles of CH2NH2COOH = Given mass/ Molar mass
moles of CH2NH2COOH = 30/75 = 0.4 mol
One mole of CH2NH2COOH contains 32 gram of oxygen
0.4 mole of CH2NH2COOH will contain = 0.4 × 32= 12.8 g of oxygen
Answer- the mass of oxygen in 30 g of CH2NH2COOH is 12.8 gram!
No, it won't change the amount of reactants nor the products as a catalyst will only provide an alternative path where lower activation energy is needed for the process to take place.
hope this explains it
If it does, please give it a brainliest :)))
Answer:
c
Explanation:
kinetic energy can be calculated using the formula
=1/2*mass*velocity or speed ^2
