Answer: Option (d) is the correct answer.
Explanation:
It is given that mass of is 137.0 g.
Molar mass of is as follows.
Molar mass of = 2 × 14 + 3 × 16
= 76 g
Thus, number of moles will be calculated as follows.
No. of moles =
=
= 1.803 mol
There are 2 nitrogen (N) atoms present in the formula of dinitrogen trioxide. Also Avogadro's number equals atoms or molecules per mol.
Therefore, number of N molecules or atoms in is as follows.
Number of N atoms =
= atoms
= atoms
Thus, we can conclude that there are atoms of N in in 137.0 grams of .
Cathode! hope that helps you out.
Answer:
C) in either position
Explanation:
There are two kinds of membrane protein:
a) Integral proteins: They have a fixed or permanent association with the membrane. They are majorly embedded in the middle layer of membrane. A kind of integral proteins are transmembrane proteins, they can cross the membrane and are path for transport of ions or molecule in and out cell.
b) Peripheral proteins: The are confined to the surface of membrane and are boned with ionic interactions. they are more in number as compared to integral proteins.
Answer:
ions need to be present in the water. If there are no ions in solution, no electricity is conducted. since, in water, electricity is conducted, this means that HCl completely ionizes to H + and C l − ions. However, in chloroform, since there is no conduction, HCl does not ionize and stays as the
Explanation:
Some atoms become unstable because NEUTRONS AND PROTONS ARE OFF BALANCE.
Neutrons and protons are the subatomic particles, which are found inside the nucleus. A nucleus is described as stable when its binding energy is enough to hold the nucleus together. When the binding energy is not enough to hold the nucleus together, the nucleus is described as unstable. In order to become stable the nucleus will lose protons and neutrons. <span />
