The table compares the type of reactants and products taking part in two chemical changes. Which of the following statements correctly identifies the synthesis reaction and explains why? (5 points) O Only chemical reaction X, because one reactant is a compound
O Only chemical reaction Y, because both reactants are elements
O Neither chemical reaction X nor Y, because they have only one product
O Both chemical reactions X and Y, because there are two reactants and a single product​

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

the maximum mass of nh3 is nh3 in grams

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.
