WILL GIVE BRAINLIEST FOR A CORRECT ANSWER Aqueous BaCl2 reacts with aqueous MgSO4. Predict the products and write a full balanced chemical equation. (Hint: the reaction type will be a double replacement; SO42- is a polyatomic ion; use the periodic table to predict the charges of Ba, Cl, and Mg. Remember, you can predict the charges of elements based on their group number).

Explanation:

BaCl2(aq)+Na2SO4(aq)→BaSO4(s)+2NaCl(aq)

The types of reactions are (b) Precipitation and (d) Double displacement.

A precipitate of bariumsulphate is obtained.

In double displacement reaction, two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.

and involves Precipitation and Double displacement of reaction

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
