Answer:
Liquid A
Explanation:
the least dense will be at the top. like icecubes in water. the ice is less dense than the water so it floats
Answer:
I'm pretty sure it's C I'm sorry if I'm wrong
Answer:
12 molecules of carbon dioxide
24 molecules of water
Explanation:
Given parameters:
Number of molecules of methane = 12 molecules
Unknown:
Number of molecules of carbon dioxide = ?
Number of molecules of water = ?
Solution:
The given amount of methane is the limiting reagent in this reaction. By this, we can ascertain the amount of products that will be formed and the extent of the reaction.
We first write the balanced chemical equation for this reaction;
CH₄ + 2O₂ → CO₂ + 2H₂O
From balanced equation;
1 mole of methane produced 1 mole of carbon dioxide
12 molecules of methane will produce 12 molecules of carbon dioxide
Also;
1 mole of methane produced 2 moles of water;
12 molecules of methane will produce (12 x 2)molecules = 24 molecules of water
Answer:
isotopes
Explanation:
isotopes of the elements where the nucleas is unstable generally releases nuclear radiation.
