From the unbalanced equations below, identify the one that does not represent a redox reaction. a. h2co3(aq) → co2(g) + h2o(l) b. c(s) + h2o(g) → co(g) + h2(g) c. s2o32- (aq) + i2(s) → s4o62+ (aq) + i-(aq) d. febr2(aq) + br2(l) → febr3(aq)

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.

Can someone me with 3 and 4 plz. this is for masteries test.

What are the chemical names of these compounds? ke: mg3n2: reset next
