Answer:
6 neutrons. The mass number is the number of protons and neutrons in the nucleus of an atom. The atomic number shows how many protons. Subract the atomic number from the mass number to find the number of neutrons.
Explanation:
Answer:
0.18 moles
Explanation:
Applying,
PV = nRT................... Equation 1
Where P = pressure, V = volume, n = number of moles, R = molar gas constant, T = temperature.
make n the subject of the equation
n = PV/RT............... Equation 2
Given: V = 5.3 L, T = 22 °C = (22+272) K = 295 K, P = 632 mmHg = (0.00131579×632) = 0.8316 atm, R = 0.083 L.atm/K.mol
Substitute these values into equation 2
n = (0.8316×5.3)/(0.083×295)
n = 0.18 moles
Answer:
Blackbody radiation
Explanation:
This phenomenon described by Susan is know as black body radiation. Different materials by color reacts to incident radiation on them in diverse manner.
- A white surface will reflect all the wavelength of light incident on it.
- A black surface will absorb all the wavelength of light on it.
This absorption causes the black surface to be hotter compared to other surfaces.
I believe the pH is 7. If you would like me to explain comment.
I can’t see what image you have to refer too but India is now part of the rest of Asia due to continental plates running into eachother.
