Answer
Molecular Mass for CF4 = 88.004349 Da
Answer:
+2.5
Explanation:
So the oxidation number of S in Na2S4O6is +2.5.
Answer:
Hydrolysis
Explanation:
The phosphate groups in an ATP molecule are joined forming an ester group. Esters can be formed when an alcohol (-OH) bonds with an acid (-COOH, or, in the case of phosphoric acid, 
). When this bonding occurs, the two molecules together lose a molecule of water, because the alcohol loses the hydroxyl and the acid loses an hydrogen, and the three atoms combine to form water. All the chemical bonds that are formed with the loss of a water molecule can also be broken using water, and this reaction is called hydrolysis.
You can demonstrate that a piece of chalk has mass by putting it on a pan scale. Pan scales determine mass in grams. Also if the mass feels like it has some weight to it (although not to be confused with weight, they are two different things!), it most likely has mass.
Hope this helps!!
