Answer the following for the reaction: 2HCl(aq)+CaCO3(s)→CO2(g)+H2O(l)+CaC l2(aq) What is the molarity of a HCl solution if the reaction of 204 mL of the HCl solution with excess CaCO3 produces 12.4 L of CO2 gas at 725 mmHg and 20. ∘C?

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
