You have 2 moles of Putrescine being held at 1 atm and 273 K. What volume, in liters, will this take up?
a.0 0.089 L
b.22.4L
c.44.8 L
d. Not enough information to solve the problem.

I think b will be your answer

Explanation:

bc it makes a lot of sense

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
