Answer:
0.427 g HClO4
Explanation:
[H+]= 10^-3.3 = 5.01 x 10^-4 M
8500 mL=8.5 L
M= mol solute/ L solution
mol solute= M* L solution
mol solute= (5.01 x 10^-4 M * 8.5 L)
mol solute= 4.26 x 10^3 mol HClO4
1 mol HClO4 -> 100. 4 g
4.26 x 10^3 mol HClO4 -> x
x=0.427 g HClO4
Answer:
1.21 times
Explanation:
The energy of a wave is proportional to the square of the amplitude of the wave.
Mathematically:

where
E is the energy of the wave
A is its amplitude
In this problem, the amplitude of the wave increases by a factor of 1.1; it means that the new amplitude can be written as

Therefore, this means that the energy of the wave increases by a factor:

Therefore, the energy of the wave increases by a factor 1.21.

I got it right on my test
Answer:
The sample will be heated to 808.5 Kelvin
Explanation:
Step 1: Data given
Volume before heating = 2.00L
Temperature before heating = 35.0°C = 308 K
Volume after heating = 5.25 L
Pressure is constant
Step 2: Calculate temperature
V1 / T1 = V2 /T2
⇒ V1 = the initial volume = 2.00 L
⇒ T1 = the initial temperature = 308 K
⇒ V2 = the final volume = 5.25 L
⇒ T2 = The final temperature = TO BE DETERMINED
2.00L / 308.0 = 5.25L / T2
T2 = 5.25/(2.00/308.0)
T2 = 808.5 K
The sample will be heated to 808.5 Kelvin
