Me! two groups of students were tested to compare their speed working math problems. each group was given the same problems. one group used calculators and the other group computed without calculators.

1.) what is the independent variable?

2.) what is the dependent variable?

3.) what is the constant variable?

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.

How many moles of carbon dioxide will form if 2.5 moles of c3h8 is burned
