Answer:
B. man with a beard
Explanation:
it is not a genetic mutation because it is completely natural and common unlike the other options.
The answer is C. 186. 6 g
The molar mass (Mr) of Mg(OH)₂ is the sum of atomic masses (Ar) of the elements.
Ar(Mg) = 24.3 g/mol
Ar(H) = 1
Ar(O) = 16
Mr(Mg(OH)₂) = Ar(Mg) + 2Ar(O) + 2Ar(H) = 24.3 + 2· 1 + 2 · *16 = 24.3 + 2 + 32 = 58.3 g/mol
Now, make a proportion. If 58.3 g are in 1 mol, how much will be in 3.2 mol:
58.3 g : 1 mol = x : 3.2 mol
x = 58.3 g · 3.2 mol ÷ 1 mol = 186.56 ≈ 186.6 g
Matter is a lot like energy.
<em>It can't be created or destroyed</em>. It can only be moved around, shifted, rearranged, transformed, disguised, etc. Never created or destroyed.
If you suddenly see some matter that wasn't there a moment ago, it had to come from somewhere. It couldn't just appear out of nothing.
If you suddenly STOP seeing some matter that was there a moment ago, it had to go somewhere. It couldn't just disappear into nothing.
So.......
here,
Mass (m) = 20g
Change in Temperature (ΔT) = 29C-10C
= 19C
Specific Heat Capacity = 0.1 cal/ g C
now, plug the info. into the formula,
specific heat capacity = quantity of heat / (mass * change in temperature)
0.1 = quantity of heat / (20 * 19)
0.1 = quantiy of heat / 380
0.1 * 380 = quantity of heat
38 = quantity of heat
so the granite rock boulder absorbed 38 calories of heat energy from the sun
Oil is a lubricant which helps increase friction. when u spread sand on a place where oil is spilled the sand reduces friction between road and vehicle tire. the vehicle wont skid.
