Explanation:

Equation of reaction

BaSO₄ + H₂SO₄ → Ba(HSO₄)₂

From the above equation of reaction, it is evident that there are 2 atoms in the product side of the reaction which is only logical because every chemical reaction obey the law of conservation of mass which states that matter can neither be created nor destroyed but can changed from one form to another.

In the reactant side, we have 2 atoms of S from the two reactants coming together.

One sulfur atom from BaSO₄ and the other from H₂SO₄. So therefore, only 2 sulfur can be produced since the reaction has to observe law of conservation of matter

Answer:

Option D. 1092K

Explanation:

T1 = 273K

V1 = V

P1 = P

V2 = 2V( i.e double of original volume)

P2 = 2P (i.e double of original pressure)

T2 =?

P1V1/T1 = P2V2/T2

PV/273 = 2P x 2V / T2

Cross multiply to express in linear form

PV x T2 = 273 x 2P x 2V

Divide both side by PV

T2 = (273 x 2P x 2V) / PV

T2 = 273 x 2 x 2

T2 = 1092K

Xianming runs a titration and collects, dries, and weighs the BaSO4(s) produced in the experiment. He reports a mass of 0.2989 g

The question is incomplete, here is the complete question:

$Ba(OH)_2(aq.)+H_2SO_4(aq.)\rightarrow BaSO_4(s)+2H_2O(l)$

Xianming runs a titration and collects, dries, and weighs the $BaSO_4(s)$ produced in the experiment. He reports a mass of 0.2989 g go $BaSO_4$ Based on this, calculate the concentration of $Ba(OH)_2$ solution.
