1 answer:

8 0

A chemical sodium carbonate (Na2CO3), produced by reacting sodium chloride and limestone, is commonly known as soda ash.

Soda ash has a number of chemical properties and one of the important properties is that it a basic i.e. an alkaline compound. It can be used as a pH regulator for a number of processes such as raising the pH of a swimming pool.

It is also a good electrolyte and can make a good conductive solution when add to water.

1. 10.0 g of CaCO 3 on heating gave 4.4 g of CO 2 and 5.6 g of CaO. The observation is in agreement with the law of conserva

finlep [7]

Answer:

According to the law Mass of reactants = mass of product, here `underset(10 g)(CaCO_(3))rarr underset(4.4 g)(CO_(2))+underset(x)(CaO)` Hence, x = 10 g - 4.4 g = 5.6 g Which is mass of CaO.d
In the first compound Hydrogen = 5.93 % Oxygen = `(100-5.93)% = 94.07 %` In the second compound Hydrogen = 11.2 % Oxygen `= (100-11.2)%=88.8%` In the first compound the number of parts by mass of oxygen that combine with one part by mass of hydrogen `=(94.07)/(5.93)=15.86` parts ...
(The ratio of Cu combining with fixed weight of oxygen in black and red oxide is 1 : 2 respectively. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.) {Check something more in the above attachment!}

if a 1.85g mass of zinc produces 475 mL og gas and your balloon weighs 0.574 g and the room temperature is 20.5°C. calculate the

aleksley [76]

You will use an ideal gas equation here. Let us denote 'x' as the unknown sample of zinc if another 1 ml of it is added to make a total of 476mL gas. The ideal gas equation is PV = nRT. Assume atmospheric conditions and then substitute everything to the equation.

(1atm)(0.476L) = (1.85 + x)(0.08206 L-atm/mol-K)(20.5+273K)
x = 1.83 g of zinc
