The city itself. Maybe from body heat and human activities.
Explanation:
B. The light bends in the water causing the straw to look different.
This happens due to the refraction of light.
Answer:
If pOH is 3.05, pH is 10.95 or
[H+]=1.122⋅10−11 mol/L
Explanation:
pH=−log(H+)Now, what is H+
if your pH is 10.95 (since pH+pOH=14, your pH=10.95).
(H+)=10 −10.95
(H+)=1.122⋅10 −11
This is your hydrogen ion concentration: [H+]=0.00000000001122 mol/L
<span>1. The value of x if the rate doubles when [A] is doubled is that </span><span>x = 1
</span><span>2. Then if the rate quadruples when [A] is doubled is that x= 2
Since x=1 when the rate doubles, so if it quadruples, it will be times 2.
So the solution to this is 1 times 2= 2
x=2</span>
Resulting pressure is 13.6 atm.
<u>Explanation:</u>
Using Ideal gas equation, we can find the pressure of the gases formed in the reaction.
PV = nRT
Number of moles, n = given mass / molar mass = 20 g / 18 g/mol
= 1.11 moles
Volume, V = 2 L
Temperature, T = 25°C + 273 = 298 K
R = gas constant = 0.08206 L atm K⁻¹ mol⁻¹
P = nRT/V
= 1.11×0.08206 ×298 / 2
= 13.6 atm
