Answer:
37.046 grams of oxygen gas were produced.
Explanation:
Moles of potassium chlorite = 
According to reaction 2 moles of potassium chlorite gives 3 moles of oxygen gas.
Then 0.7718 moles of potassium chlorite will give:
of oxygen gas.
Mass of 1.1577 moles of oxygen gas:
1.1577 mol × 32 g/mol = 37.046 g
37.046 grams of oxygen gas were produced.
Answer:
C- A proton has about the same mass as a neutron .
Explanation:
In an atom such as a carbon atom, the masses of the proton and neutrons are the same.
The mass of the electrons is very negligible.
- Protons are the positively charged particles in an atom
- Neutrons do not carry any charges
- Both protons and neutrons have similar masses.
- They contribute the bulk of the mass of the atom.
- The electrons carry negative charges and they have negligible masses.
The mass of protons and neutrons are similar.
