Ok they are both can formed by the same high pressure system . the heat waves are extended periods of above-normal temperatures . but the cold wave is an extended periods of below normal temperatures

Number of nucleon =
Molarmassofnucleon
Massofatom
=
1.6726×10

g
=19.8=20(approximately)
It is given that element comprises of 2 atoms
Hence,number of nucleon = 2×20=40

You have 4.70 mol H2O
There are two H atoms in 1 molecule H2O.
Therefore, there must be 2*4.70 = 9.40 mols H in 4.70 mols H2O.
How many mols O in 4.70 mols H2O? That's 4.70 mols, of course.
Said another way, you have 2 mols H for every 1 mol H2O and 1 mol O for every 1 mol H2O.
So for 50 mols H2O you have 100 mols H and 50 mol O.
Depending if the reaction is a reversible or an irreversible one, the direction of the arrow will point in one direction or 2 directions from reactants to products.
Hello!
<span>a. gains a proton and loses a neutron. </span>This process gives more stability to the atom.
