Caco3 + 2hcl --> cacl2 + co2 + h2o in the reaction above, what mass of carbon dioxide is produced when 10 moles of hcl reacts with excess calcium carbonate?

Which fact represents evidence for the big bang theory?

In a ni-cd battery, a fully charged cell is composed of nickelic hydroxide. nickel is an element that has multiple oxidation states. assume the following proportions of the states: nickel charge proportions found 0 0.17 +2 0.3 +3 0.33 +4 0.5 (a) determine the mean of the nickel charge. enter the answer to 2 decimal places.(b) determine the cumulative distribution function of nickel charge.

At the current rate, a graph of carbon dioxide produced by fossil fuels over time would slope upward slope downward be horizontal be vertical
