It would be A, the molecules should be closely packed together but arranged randomly. :)
Answer: atoms of hydrogen are there in
35.0 grams of hydrogen gas.
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
1 mole of hydrogen = atoms
17.5 mole of hydrogen = atoms
There are atoms of hydrogen are there in
35.0 grams of hydrogen gas.
20 g O2 x 1 mol O2/32 g O = 0.625 mol O2
Adults have stem cells because they are needed to repair certain tissues in the body such as in the muscles, bone marrow, skin, teeth, heart, and liver, to name a few. Thus, they can develop into many different cell types and function to replace older and damaged tissues.
It would be considered a Homogeneous Mixture. A mixture with two or more components mixed evenly is a Homogeneous mixture.
