10. What do you have to do to the coefficients of equation I below to get to equation II? i. 2 SnO2 + 4 H2  2 Sn + 4 H2O
ii. SnO2 + 2 H2  Sn + 2 H2O

a) Both equation I and II are balanced, but equation I is the correct way to write the balanced equation.

b) Can you divide equation II by another factor and still have it be correct? Why or why not?

c) In a complete sentence, write down a method you could use to determine if an equation is written in the correct way.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
