3.44x10^2
you move the decimal over to get a single digit number with change. The number of times you move the decimal is the number for the 10 power
1 mmol --------------------- 1000 <span>µmol
( mmol ) -------------------- </span> 38231 µmol
mmol = 38231*1 / 1000
mmol = 38231/ 1000
=> 38.231 mmol
The answer for the following problem is mentioned below.
- <u><em>Therefore the final volume of the gas is 52.7 ml.</em></u>
Explanation:
Given:
Initial pressure (
) = 290 kPa
Final pressure (
) = 104 kPa
Initial volume (
) = 18.9 ml
To find:
Final volume (
)
We know;
From the ideal gas equation;
P × V = n × R × T
where;
P represents the pressure of the gas
V represents the volume of gas
n represents the no of the moles
R represents the universal gas constant
T represents the temperature of the gas
So;
P × V = constant
P ∝ ![\frac{1}{V}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BV%7D)
From the above equation;
![\frac{P_{1} }{P_{2} } = \frac{V_{2} }{V_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7BP_%7B1%7D%20%7D%7BP_%7B2%7D%20%7D%20%20%3D%20%5Cfrac%7BV_%7B2%7D%20%7D%7BV_%7B1%7D%20%7D)
represents the initial pressure of the gas
represents the final pressure of the gas
represents the initial volume of the gas
represents the final volume of the gas
Substituting the values of the above equation;
= ![\frac{V_{2} }{18.9}](https://tex.z-dn.net/?f=%5Cfrac%7BV_%7B2%7D%20%7D%7B18.9%7D)
= 52.7 ml
<u><em>Therefore the final volume of the gas is 52.7 ml.</em></u>
Answer:
H₂SO₄ (aq) + 2LiOH (aq) ⇒ Li₂SO₄ (aq) + 2H₂O (l)
Explanation:
This is an acid-base reaction, so we know the products are going to a salt/ionic compound and water.
Answer:
H2
Explanation:
I would say H2 cause CH4 have less hydrogen gas .
