Answer:
the volume of the gas decreases
Explanation:
As a balloon rises through the atmosphere, the air pressure around it decreases and the balloon expands.
Good luck!
Answer:
304.9m
Explanation:
Given
Velocity = 300m/s
Tim = 1sec
Required
Horizontal distance S
Using the formula
S= ut+1/2gt²
S = 300(1)+1/2(9.8)(1)²
S = 300+4.9
S = 304.9m
Hence the distance travelled is 304.9m
4.5 Joules. I think it'd be 4.41, but when you round it, it's 4.5.
Answer:
In Step 5, you will calculate H+/OH– ratios for more extreme pH solutions. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide for a solution at a pH = 2. Then divide the H+ concentration by the OH– concentration. Record these concentrations and ratio in Table C.
What is the concentration of H+ ions at a pH = 2?
0.01 mol/L
What is the concentration of OH– ions at a pH = 2?
0.000000000001 mol/L
What is the ratio of H+ ions to OH– ions at a pH = 2?
10,000,000,000 : 1
