In an experiment, you react 12.0 grams of hydrobromic acid (HBr) with 3.0 grams of aluminum metal. You capture some gas from the reaction, and find its weight to be 0.5 grams. Write a word equation for this reaction.
What type of reaction is this?
What is the chemical name of the second product formed (not the gas)?
What is the mass of the second product?

The covalent compound acetylene, which is the fuel of the oxyacetylene torch used by welders, has the molecular formula c2h2. the covalent compound benzene, a commercial solvent, has the molecular formula c6h6 each of these covalent compounds contains carbon and hydrogen atoms in a one-to-one ratio. would it be correct to write the chemical formulas of each as ch? explain.

Explanation for basic character?
