If 18 grams of oxygen reacts completely with 4 grams of hydrogen, we would expect how many grams of water? A.) Less than 22 grams because some mass is lost in the reaction
B.) More than 22 grams because the oxygen gains mass during the reaction
C.) 22 grams because mass cannot be created or destroyed
D.) There is no way to tell from this information.

The chemical bond connecting one nucleotide with the next one along the nucleic acid chain is called a

Click the button that shows the correct relationship of the electron affinities of the elements sodium and phosphorus. sodium’s electron affinity value is more negative than the electron affinity value of phosphorus. phosphorus’ electron affinity value is more negative than the electron affinity value of sodium. this information cannot be determined using the periodic table. answer is b on e2020.

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
