Can someone please help me?

Chemistry
1 answer:
Svet_ta [14]3 years ago
4 0

Answer:

D,E, and F are correct

Explanation:

Longer wavelengths = lower frequencies = lower energy

Shorter wavelength = high frequency = higher energy

Gamma rays have shortest wavelength and therefore highest frequency and energy

Radio waves equally have a shorter wavelength and therefore high frequency and energy

A container holds 35.8 moles of gas under 10.0 atm of pressure at 70.0 C. What is the volume of the container?
zhenek [66]
THE ANSWER

for solving this, we just use the formula of the equation of state

PV = n RT
where
P: pressure =10atm
V volume
n number of mole = 35.8 moles
R universal gas constant = 0.082
T: The temperature= 70°C= 343.15 Kelvin

therefore, for finding V
we have 
 
V= (n RT) / P = 35.8 x 0.082 x 343.15   / 10 = 100.7 ≈ 101 L

the answer is V = 101L

Determine the amount of heat energy in joules required to raise the temperature of 7.40g of water from 29.0OC to 46.0 OC.
valina [46]

Answer: The amount of heat energy in joules required to raise the temperature is 526 Joules

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q=m\times c\times \Delta T

Q = Heat absorbed = ?

m= mass of substance = 7.40 g

c = specific heat capacity = 4.184J/g^0C

Initial temperature of the water = T_i = 29.0°C

Final temperature of the water = T_f  = 46.0°C

Change in temperature ,\Delta T=T_f-T_i=(46.0-29.0)^0C=17.0^0C

Putting in the values, we get:

Q=7.40g\times 4.184J/g^0C\times 17.0^0C

Q=526J

The amount of heat energy in joules required to raise the temperature is 526 Joules
