Given the equation: HCI + Na2SO4 ---> NaCl + H2SO4 Hint: you should balance the equation If you start with 2.0 g of HCl (hydrochloric acid), how many grams of H2SO4 (sulfuric acid) will be produced?​

approx 2.45g

Explanation:

2HCl + Na2SO4 → 2NaCl + H2SO4

 2    :       1           :      2       :      1

0.05                                     0.025 (moles)

⇒ mH2SO4 = 0.025 × 98 = 2.45 g

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
