Protons: charge +1, have a mass of 1 and are found in the nucleus
Neutrons: charge 0, have a mass of 1 and are found in the nucleus
Electrons: charge -1, have a mass of 1/840 and are found on the outside of the nucleus
hope that helps
The answer is (3)Ne. Usually, the elements belongs to group 18 all have completely filled valence electron shell. Among the four elements carbon, vanadium, neon and antimony, only neon belongs to group 18.
Answer:
Option C.
The Bohr effect describes the effect of pH on the affinity of hemoglobin for oxygen.
Explanation:
The hemoglobin is the oxygen carrying part of the blood. However, According to Christian Bohr, the binding affinity for oxygen by the hemoglobin in the blood is greatly affected by the acidity and content of carbon dioxide in the blood. As a matter of fact, they are inversely related. The more acidic the blood is, or the lower the pH of the blood, the lower the amount of oxygen that can become bonded with the hemoglobin in the blood.
Answer:
M = 35 g/mol
Explanation:
Given data:
Density = 2.5 g/L
Pressure = 1.8 atm
Temperature = 30°C (273.15 +30 = 303.15 K)
Molar mass = ?
Solution:
d = PM/RT
M = dRT/P
M = 2.5 g/L × 0.0821 atm.L/mol.K × 303.15 K / 1.8 atm
M = 62.22 atm. g/mol/ 1.8 atm
M = 35 g/mol
Answer:
the answer is B no need to struggle ur answer is correct
