Answer:
The pressure is
Explanation:
From the question we are told that
The mass of the carbon monoxide is
The temperature at which takes place
The volume of the sealed vessel is
Generally the ideal gas law is mathematically represented as
Where R is the gas constant with value
n is the number of moles of carbon monoxide which is mathematically evaluated as
where is the molar mass of carbon monoxide which is a constant with value
So
Now Making P the subject we have
The correct answer is letter A. We use the formula, <span>v=vo + at to get the answer.</span>
<span>
v=vo + at </span>
<span>v=0 + (9.8)(8) </span>
<span>v=78.4 </span>
<span>y=1/2(vo + v)t </span>
<span>y=1/2(78.4)(8) </span>
<span>y=1/2(627.2) </span>
<span>y=313.6m

When ph decreases the hydrogen ion concentration increases because ph = - log (H)
Likewise, the other way around is true (when hydrogen ion concentration increases, pH decreases).
The balanced reaction would be as follows:
<span>3NaOH + H3PO4 --> Na3PO4 + 3H20
We are given the concentration and the amount of the reactants to be used. We use these values for the calculations as follows:
</span><span>How many mL of .225 M NaOH will react with 4.568g H3PO4?
4.568 g (1 mol / 98 g) ( 3 mol NaOH / 1 mol H3PO4 ) ( 1 L / .225 mol NaOH ) = 0.621 L or 621 mL of .225 NaOH</span>
