klemol [59]
<h3><u>Answer;</u></h3>

<em>D. Have different structures and different functions</em>

A plasma membrane and a cell wall <em><u>have different structures and different functions</u></em>.

<h3><u>Explanation;</u></h3>
  • <em><u>Plasma membrane</u></em> is a structure that is found in <u><em>both animal cell and plants cells</em></u>. It is made up of a <u><em>bi-layer consisting of lipid and proteins</em></u>. Plasma membrane are semi-permeable which means the<em><u> allow selective movement of materials in and out of the cell. </u></em>
  • <em><u>Cell wall</u></em>, on the other hand is a structure that is found on plant cells and lacks in animal cell. It <em><u>contains cellulose in its structure </u></em>which enables it to be rigid and enhances it <em><u>protect the cell from mechanical damage</u></em> from harsh conditions such as pressure in the outside environment.

When 3.00 moles of hydrogen molecules and 1.50 moles of oxygen molecules react, they form 3.00 moles of water according to the r
Luden [163]

Answer:

The answer to your question is: 6 grams of hydrogen

Explanation:

Data

3.0 moles of hydrogen

1.5 moles of oxygen

3 moles of water

# of grams of hydrogen required to form 3 moles of water?

Equation

                  H₂    +   1/2 O₂        ⇒        H₂O

                3 mole    1.5 moles           3 moles

 Atomic weight of H₂ = 2 g

                         1 mole -----------------------   2 g

                         3 moles ---------------------    x

                          x = 3(2)/1 = 6 grams of hydrogens
