The following reactions all have K < 1. 1) C9H7O4- (aq) + C6H5COOH (aq) HC9H7O4 (aq) + C6H5COO- (aq) 2) C6H5COO- (aq) + CH3COOH (aq) C6H5COOH (aq) + CH3COO- (aq) 3) CH3COOH (aq) + C9H7O4- (aq) CH3COO- (aq) + HC9H7O4 (aq) Arrange the substances based on their relative acid strength.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

Answer : option a) 84explanation :

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.

Nonmetal are moldable and easily shaped
