Answer:

B. A body at rest will stay at rest until it is acted upon by another object

Explanation:

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

What is the molarity of 555 L of a Ba(OH)2 solution if the pH is 10.20?
Kipish [7]

pH is a symbolic representation of:

pH=-\log \lbrack H^+\rbrack

and for water we now that:

\lbrack H^+\rbrack\lbrack OH^-\rbrack=10^{-14}

that means the text give us the information to calculate the concentration of protons and therefore the concentration of ions OH-:

pH=10.2\rightarrow\lbrack H^+\rbrack=10^{-10.2}^{}

therefore the concentration of OH- can be calculated:

\lbrack OH^-\rbrack=\frac{10^{-14}}{10^{-10.2}}=10^{-3.8}=1.58\times10^{-4}\text{ M}

but they are not asking about the concetration of OH- they ask about concentration of Ba(OH)2 and for that we need to know the disolution stechiometry

Ba(OH)_2\rightarrow Ba^++2\times OH^-

Whic mean the concentration of Ba(OH)2 is half the concentration of OH-:

\lbrack Ba(OH)_2\rbrack=\frac{\lbrack OH^-\rbrack}{2}=7.92\times10^{-5}M
