Chlorine can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid, HCl(aq) , as described by the chemical equation

MnO2(s)+4HCl(aq)⟶MnCl2(aq)+2H2O(l)+ Cl2(g)

How much MnO2(s) should be added to excess HCl(aq) to obtain 385 mL Cl2(g) at 25 °C and 765 Torr ? mass of MnO 2

Will mark brainliest26. which of these statements are true? (3 points)a. gases are compressibleb. gases fill their containers completelyc. the pressure of a gas is independent of the temperatured. gases have masse. gases exert pressuref. the pressure of a gas is dependent on the volumeg. gas pressure results from the collisions between gas particlesh. gases have a definite volume and shape

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

What happened to the amount of carbon dioxide in the atmosphere from 2010–2017?
