Which of the following statements about the following chemical equation is 1 point correct? *
Zn + 2HCI —— ZnF, + H,
1 The equation is correctly written because all of the elements on the reactant side are
also found on the product side.
2 The equation is NOT correctly written because all of the elements on the reactant side
are also found on the product side.
3 The equation is NOT correctly written because some of the elements on the reactant
side are NOT found on the product side.

Explanation:

Some metals react with acid and replace hydrogen from the acid.

since they are more reactive than hydrogen in the electro - chemical reactivity series.

so here Zinc is acting as reducing agent or called reductant.

and Hydrogen ion is acting as an oxidant.

The vapor pressure of water at 50ºC will be greater than that at 10ºC because of the added energy and thus greater movement of the water molecules. If one knows the ∆Hvap at a given temperature, one can calculate the vapor pressure at another temperature. This uses the Clausius-Clapeyron (sp?) equation. It turns out the vapor pressure of water at 10º is 9.2 mm Hg, and that at 50º is 92.5 mm Hg.
