Robert Boyle and Robert Hooke worked together and discovered some important physics concepts. Their work lead to the formation o
Semenov [28]

Boyle's law states describes the relationship between volume and pressure for a given mass of gas and it aided our understanding of breathing.

Boyle's law states that, the volume of a given mass of gas is inversely related to its pressure at as long as the temperature is constant .

This means that, as the volume of a given mass of gas increases, its pressure decreases.

As the lungs expand during breathing, the volume of air in them increases as the pressure of air inside the lungs decreases.

Complete the isotope symbol with mass numbers of 35
amid [387]
The answer would be
35 ============= > A CL = ============> CL 17 === = ======== >Z 
37 CL 17 Isotopes mean A different and equal Z.
Isotopes are atoms that have the same number of protons but a different number of neutrons but still belong to the same element. Though they have the same atomic number but not the same mass number.

Each of the chemically active Period 2 elements forms stable compounds in which it has bonds to fluorine.(a) What are the names
Softa [21]

The names of the compound are lithium fluoride ( LiF) , beryllium difluoride (BeF2) , Boron trifluoride (BF3) , carbon tetrafluoride (CF4) , nitrogen trifluoride (NF3) , oxygen difluoride (OF2) .

Lithium is the first element of period 2 which reacts with fluorine to form LiF ( lithium fluoride ) . it is an inorganic compound . it is also a colorless solid . it is less soluble in water . it is chemically stable because of its comparable molecular mass .

Beryllium is the second element of period 2 which reacts with fluorine to give beryllium difluoride (BeF2) . it is inorganic compound . it is highly soluble in water. it is also a stable compound . it have low melting point .

Boron is the third element of period 2 which reacts with fluorine to form

BF3 (Boron trifluoride ) . it is a inorganic compound . it is colorless and toxic gas forms  . it is stable in dry atmosphere but its octet is not satisfied .

Carbon is the 4th element of the period 2 which reacts with fluorine to form carbon tetrafluoride (CF4) . it is not soluble in water . it is a greenhouse gas . it dissolves in oil. it is very stable compound .it forms covalent bond .

Nitrogen is the 5th element of period 2 which reacts with fluorine to form nitrogen trifluoride (NF3) . it is also a inorganic compound . it  is colorless and non-flammable .  it is a stable gas at room temperature .

Oxygen is the 6th element of period 2 which reacts with fluorine to form oxygen difluoride (OF2) . it is colorless poisonous gas . it is partially stable or relatively stable .

Neon is a noble gas and also a stable element . it is odorless and colorless . so it is nonreactive . so it doesn't form bond with fluorine .
