HELP I will make you brainlist!! Identify which of the following are oxidation-reduction reactions. If a reaction is a redox reaction,
name the element oxidized and the element reduced.
a. Mg(s) + Br2(l) → MgBr2(s)
b. H2CO3(aq) → H2O(l) + CO2(g)
c. CaCO3(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)
d. CuO(s) + H2(g) → Cu(s) + H2O(l)
e. Li(s) + H2O(l) → LiOH(aq) + H2(g)
f. NaCl(aq) + AgNO3(aq) → NaNO3(aq) + AgCl(s)
g. HgO(s) → Hg(l) + O2(g)
h. P4(s) + O2(g) → P4O10(s)
i. C3H8(g) + O2(g) → CO2(g) + H2O(g)
j. Al(s) + HCl(aq) → AlCl3(aq) + H2(g)

the correct answer is a

dynamic equilibrium is the answer.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
