Hey there!
Your answer is c. by the transfer of one or more electrons from one atom to another.
Ions can be positive or negative. Positive ions are called cations, and negative ions are called anions.
Electrons are transferred because two atoms have a large difference of electronegativity and the electrons are shared so unequally that the electrons are completely transferred from one atom to another, forming ions.
Hope this helps!
Answer:
Q = 43,000 calories = 180,000 joules = 180 Kilojoules
Explanation:
Heat flow for phase change can be defined as Q = m·ΔHv
ΔHv = Heat of Vaporization for water = 540 calories/gram = 2259 joules/gram = 2.259 Kilojoules/gram
m = mass of object of interest ( in this problem 80 grams steam 100°C converting to 80 grams of water at 100°C
Q = m·ΔHv = 80g x 540 cals/g =43.200 calories x 4.184 joules/cal = 180,748.8 joules (calculator answer) => 180,000 joules (2 sig. figs.) = 180 Kj
