Chemistry
1 answer:
dybincka [34]2 years ago
5 0
Answer:
D

Explanation:
Because the number of protons is the same as the atomic number, we know what the number of protons has to be 26. The mass number, 55, is the same as the number of protons plus neutrons. Lastly, because there is no charge on this atom, the number of electrons would have to be the same as the number of protons, which is 26.

High color saturation produces gray tones.
Feliz [49]
If this is a true of false question, note that it's false. Unsaturating the color, meaning giving it a lower amount up to zero, can cause gray tones - especially when it comes to pictures when editing it. High color saturation can make the color tone very vivid.

What is the temperature of a 6.1 mole sample of He gas at 18.5 bar and volume of 115L? (Round answer to the hundredths place)
Bond [772]

Answer:

4202.1 K

Explanation:

From;

PV=nRT

P= pressure of the gas = 18.5 bar

V = volume of the gas = 115L

n= number of moles of the gas =  6.1 mole

T= temperature of the gas = ?

R = gas constant = 0.083 L⋅bar⋅K−1⋅mol−1

T = PV/nR

T = 18.5 * 115/6.1 * 0.083

T = 2127.5/0.5063

T= 4202.1 K
