How do i calculate the mass of CO2 emitted per Kj of heat produced in a combustion reaction?

Chemistry
1 answer:
Alexxandr [17]3 years ago
6 0
 methanol:

1 mole CH3 OH --> produces --> 1 mole CO2 

1 mole CO2 has a molar mass of 44.01 gh/mole
 
your set up is:
(44.01 g CO2) / -726.5kJ = 0.06058g

your answer 0.06058 grams of CO2 produced per kJ released.

Nuclear fusion please help :/
fiasKO [112]

Answer:

  • The fuel for nuclear fusion is often uranium
  • Nuclear fusion is used to generate electricity at nuclear power plants

Explanation:

The most common nuclear fuel is made up of fissile elements such as Uranium, Neptunium, Plutonium,  Americium and  Curium, which are fissionable elements, which is when its nucleus is capable of undergoing a fission with neutrons free of any energy.

Nuclear fission can be used both for warlike purposes, as in the construction of atomic bombs, as well as for pacifist purposes, in the construction of reactors for the production of electrical energy.

Number of grams of hcl that can react with 0.500 grams of Al(OH)3
vlabodo [156]

Answer:

0.7g of HCl

Explanation:

First, let us write a balanced equation for the reaction between HCl and Al(OH)3.

This is illustrated below:

Al(OH)3 + 3HCl —> AlCl3 + 3H2O

Next, let us obtain the masses of Al(OH)3 and HCl that reacted together according to the equation. This can be achieved as shown below:

Molar Mass of Al(OH)3 = 27 + 3(16+1)

= 27 + 3(17) = 27 + 51 = 78g/mol.

Molar Mass of HCl = 1 + 35.5 = 36.5g/mol

Mass of HCl from the balanced equation = 3 x 36.5 = 109.5g

Now we can obtain the mass of HCl that would react with 0.5g of Al(OH)3. This can be achieved as follow:

Al(OH)3 + 3HCl —> AlCl3 + 3H2O

From the equation above,

78g of Al(OH)3 reacted with 109.5g of HCl.

Therefore, 0.5g of Al(OH)3 will react with = (0.5 x 109.5)/78 = 0.7g of HCl

What happens when chlorine from<br> CFCs mixes with ozone?
Svetach [21]

Answer:

Because they are extremely stable molecules, CFCs do not react easily with other chemicals in the lower atmosphere. ... Free chlorine atoms then react with ozone molecules, taking one oxygen atom to form chlorine monoxide and leaving an ordinary oxygen molecule.
