Answer:
the nervous system tells the muscles what to do beause your nervous sytem is hooked up to your brain
Explanation:
Answer:
11%
Explanation:
1) Calculate van 't Hoff factor:
Δt = i Kf m
0.31 = i (1.86) (0.15)
i = 1.111
2) Calculate value for [H+]:
CCl3COOH ⇌ H+ + CCl3COO¯
total concentration of all ions in solution equals:
(1.11) (0.15) = 0.1665 m
This is a molality, but we will act as if it a molarity since we will assume the density of the solution is 1.00 g/cm3, which makes the molarity equal to the molality.
0.1665 = (0.15 − x) + x + x
x = 0.0165 M
3) Calculate the percent dissociation:
0.0165/ 0.15 = 11 %
Answer:
1) conduction
2) Radiation
Explanation:
Conduction is a mode of heat transfer by which heat energy is transferred through a material, the average position of the particles of the material remaining the same.
Radiation is a process of heat transfer by which heat is transferred from a hotter to a cooler point without any intervening medium.
The pan used to fry the egg is a conductor of heat hence heat can pass through it by conduction thereby enabling the eggs to cook.
Heat can travel without an intervening medium hence Zoe feels hot near the stove. This ability of the heat to travel without an intervening medium is called radiation.
B. The study of matter and energy.
Because physical science is everything that doesn't include organic things.
