Answer: There are 4.8 x 1024 hydrogen atoms in 2.0 moles of CH4
Answer:
d. P2O5.
Explanation:
We find the ratio of the atoms by dividing the percentages by the relative atomic masses:
P : 43.6 / 30.974 = 1.4076
O: 56.4 / 15.999 = 3.5252
1.4076 : 3.5252
= 1 : 2.5
= 2:5.
So the answer is P2O5.
Answer : The resulting solution will have a pH of 7.
Explanation:
Whenever acid and base reacts with each other to form water molecule is called Neutralization reaction. This water molecules is formed from the hydronium ion () from acid and hydroxide ion() from base.
When the equal volumes of acid and base of equal strength are combined, the resulting pH of the solution becomes 7.
The pH 7 value means that the solution is neutral.
The degree to which a specified material conducts electricity, calculated as the ratio of the card density in the material to the electric field that causes the flow of current. It is the reciprocal of the resistivity.
