A ruptured tank in Anywhere, USA, spilled hydrochloric acid. Officials were reported to be concerned that the acid might mix with sodium hydroxide (caustic soda) in a neighboring tank and form a toxic gas. What toxic gas would be formed by mixing hydrochloric acid with sodium hydroxide? 1. chlorine 2. carbon dioxide 3. None 4. chlorine dioxide

Option C; NONE.

Explanation:

A chemical reaction forms new chemicals called the products from the initial chemicals called the reactants. The reaction between an acid and a base is called neutralization, and the products formed are water and a salt.

When hy­drochlo­ric acid and sodi­um hy­drox­ide is mixed together, they in­ter­act, and re­sult­ in salt and a release of heat.

The re­sult of the in­ter­ac­tion of these two high­ly ag­gres­sive com­pounds is ta­ble salt and wa­ter, these resulting com­pounds are ul­ti­mate­ly harm­less, and even ben­e­fi­cial, to hu­man be­ings.

Therefore, NO TOXIC GAS WOULD BE FORMED BY MIXING HYDROCHLORIC ACID WITH SODIUM HYDROXIDE.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
