Answer:
The volume is 13, 69 L
Explanation:
We use the formula PV=nRT. We convert the temperature in Celsius into Kelvin and the pressure in mmHg into atm.
0°C= 273K---> 56°C= 56 + 273= 329K
760 mmHg----1 atm
719 mmHg----x= (719 mmHgx 1 atm)/760 mmHg= 0,95 atm
PV=nRT ---> V= (nRT)/P
V=( 0,482 molx 0,082 l atm/K mol x 329K)/0,95 atm
<em>V=13,68778526 L</em>
Remark
The balance numbers in front of the chemicals tell you how to set up the proportion to solve your question
For every 2 moles Na only 1 mole of Cl2 is required.
Equation
2 moles Na:1 mole Cl2 :: x moles Na:4 moles Cl2
Solution
2/1 = x/4 Cross multiply
2*4 = x*1
8 = x
Conclusion
8 moles of Na will be used. <<< Answer
Answer:
The higher up an object is the greater its gravitational potential energy. ... As most of this GPE gets changed into kinetic energy, the higher up the object starts from the faster it will be falling when it hits the ground. So a change in gravitational potential energy depends on the height an object moves through.
The answer is to increase the surface area of the solute.
You see it dissolves faster because there is a lot more water touching it when it is has a higher surface area.This can be achieved by crushing
Answer: New concentration of
is 0.23 M.
Explanation:
The given data is as follows.
Moles of
= 0.06 mol
Moles of
= 0.08 mol
Therefore, moles of
added are as follows.
Moles of
= 
= 0.003125 mol
Now, new moles of
= 0.06 + 0.003125
= 0.063125
Therefore, new concentration of
will be calculated as follows.
Concentration = 
= 0.23 M
Thus, we can conclude that new concentration of
is 0.23 M.
