Answer:
P₂= 116.7 atm
Explanation:
Here apply the Boyle's law equations that states :at constant temperature the volume of a dry mass of a gas is inversely proportional to its pressure.
This is simplified as;
P₁V₁=P₂V₂ where P is pressure and V is volume
Given that;
P₁=1
V₁=1.81 m³
P₂=?
V₂=1.55*10^-2 m³
Apply the formula
1*1.81 =P₂*1.55*10^-2 m³
1.81/1.55*10^-2 =P₂
P₂= 116.7 atm
Answer:
c) 0.10M NaCl
Explanation:
<em>Options are:</em>
<em>a) 0.20M NaCl</em>
<em>b) Very acidic</em>
<em>c) 0.10M NaCl</em>
<em>d) 0.10M HCl + 0.20M NaOH</em>
<em>e) Slightly acidic.</em>
<em />
Based on the reaction:
NaOH + HCl → H₂O + NaCl
You can see than 1 mole of NaOH reacts per mole of HCl producing 1 mole of NaCl
Assuming 1L of 0.20M HCl reacts with 1L of NaOH, moles of both compounds are:
1L * 0.20mol/L = 0.20 moles reacts. That means moles of NaCl produced are 0.20moles in 2L. Molarity of NaCl is:
0.20mol / 2L = 0.10M NaCl
That means, right option is:
<h3>c) 0.10M NaCl</h3>
Answer:
The maximum amount of water vapor the air can hold at a given temperature is known as the Saturation Point, it is also identified as 100% relative humidity.
