Answer:

O = 94.117%

H = 5.882%

Explanation:

Hydrogen peroxide (H202) Molar Mass = 34g

OH 1-  17g/mol

H 1+ = 1g/mol

O = 16g/mol

2 Grams H

32 grams O

Percentage composition of  Hydrogen peroxide

O = 32/34 = 94.117%

H =    2/34 =   5.882%

How much energy would be absorbed as heat by 75 g of iron when heated from 295 k to 301 k?
Katen [24]

Answer:

Q=202.5J

Explanation:

Hello,

In this case, the increase in the temperature involves the addition of heat that is defined in terms of mass, heat capacity and temperature:

Q=mCp(T_2-T_1)

In this case, the heat capacity of iron is 0.450 J/(g*K), thus the heat results:

Q=75g*0.450\frac{J}{g*K}*(301-295)K\\\\Q=202.5J

In such a way, since the temperature is increased heat is added, that is why it is positive.

Best regards.

During a sunset, molecules interact with light and scatter all but which colors?
sergey [27]

Answer:

B.red

Explanation:

Electromagnetic spectrum is range of the frequencies and their respective wavelengths of the various type of the electromagnetic radiation.

In order of the decreasing wavelength the spectrum are:  

Red , Orange, Yellow, Green, Blue, Indigo, Violet

Increasing wavelength is the opposite trend. Thus, The longest visible wavelength is red and the shortest is violet.

Also, Violet light gets scattered the most while the red light gets scattered the least.

During the time of the sunset, the Earth is rotating away from the Sun. Thus, most of the light colors scatters in the ways and the color that least scatter which is red reaches the Earth.

That's why, at the time of sunrise and sunset, the sky looks red.
