D. Liquid to gas. This is the only answer that demonstrates molecules heating up and moving quicker.
Answer:
is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results
Answer:
2.5 mole of O2
Explanation:
From the equation we see that we need 5 molecules of oxygen to react with 2 molecules of C2H2.
This means that 5 moles of oxygen molecules are needed to completely react with 2 moles of C2H2, because a mole is a unit of particle count.
From that we can infer that to react with 1 mole of C2H2 we need half of 5 moles of oxygen - so 2.5 mole of oxygen molecules.
Hi there!
To solve, we can use dimensional analysis to convert from molecules to grams.
We must use Avogadro's number (6.02 × 10²³) in converting from molecules to moles.
After converting, multiply by the atomic mass, or grams per mole.
