Answer:
Both
Explanation:
The combined gas law is also known as the general gas law.
From the ideal gas law we assume that n = 1;
So;
PV = nRT
and then;
=
If we cross multiply;
P₁V₁T₂ = P₂V₂T₁
So;
T₁ = ![T_{2} \frac{P_{1}V_{1} }{P_{2} V_{2} }](https://tex.z-dn.net/?f=T_%7B2%7D%20%5Cfrac%7BP_%7B1%7DV_%7B1%7D%20%20%7D%7BP_%7B2%7D%20V_%7B2%7D%20%7D)
Also;
V₂ = ![V_{1} \frac{P_{1} T_{2} }{P_{2} T_{1} }](https://tex.z-dn.net/?f=V_%7B1%7D%20%5Cfrac%7BP_%7B1%7D%20T_%7B2%7D%20%7D%7BP_%7B2%7D%20T_%7B1%7D%20%7D)
So from the choices both are correct
Answer:
5 m/s 2
Explanation:
if the car moved from 00 to 1-5 then to 2_10 you can know that it is going up in velocity but 5 a second so 5 m a second. hope this helps
Answer:
D. 6.3 x 10-5 mol/L NaOH
Explanation:
Alizarin yellow is an indicator that is yellow when pH < 10.1. In the same way, thymol blue is blue when pH > 9
That means the pH of the solution is between 9 - 10.1
Any acid as HCl could have a pH of these.
The solution of 3.2x10⁻⁴M NaOH has a pH of:
pOH = -log[OH-] = 3.49
pH = 14-pOH = 10.51. The pH of the solution is not 10.5
Now, the solution of 6.3x10⁻⁵M NaOH has a pH:
pOH = -log[OH-] = 4.2
pH = 14-pOH = 9.8
The pH of the solution could be 9.8. Right option is:
<h3>D. 6.3 x 10-5 mol/L NaOH</h3>
