Answer:

Robert Boyle

Explanation:

Robert Boyle was an Irish chemist and is famously referred to as the first modern chemist. He was born on the 25th of January, 1627 in Lismore, Ireland and died on the 31st, December 1691, London, United Kingdom.

Robert Boyle was the first to determine the relationship between the pressure and volume of a gas.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

PV = K

P_{1}V_{1} = P_{2}V_{2}

Where;

V1 and V2 represents the initial and final volumes respectively.

T1 and T2 represents the initial and final temperatures respectively.

Complete and balance the molecular equation for the reaction of aqueous sodium carbonate, Na 2 CO 3 , and aqueous nickel(II) chl
pantera1 [17]

Answer:

NiCl2 (aq) + Na2CO3 (aq) ---> NiCO3 (s) + 2NaCl (aq)

Explanation:

Soluble ionic compounds exist as ions in solution.

Na 2CO3, will contain Na2CO3 (aq) --> 2Na ^+ (aq) + CO2 ^-3 (aq)

The same way, a solution of calcium chloride,  

CaCl 2, will contain CaCl2 (aq) --> Ca2^+ (aq) + 2Cl^−  (aq)

Mixing both solution, the calcium cations  

Ca 2^+ , will apir up with the carbonate anions,  CO2^−3 , and form the Insoluble calcium carbonate, CaCO ^3, which precipitates out of solution.

The complete ionic equation, which features all the ions that are present in solution, will be like this

2 Na^+ (aq) + CO2^−3 (aq) + Ca2^+ (aq) + 2Cl^−  (aq) --> CaCO 3 ↓ (s)  + 2Na^+ (aq) + 2Cl^− (aq)

Notice that you have two sodium cations and two chloride anions on the products' side, which is why you have  2NaCl

NiCl2 (aq) + Na2CO3 (aq) ---> NiCO3 (s) + 2NaCl (aq)
