The answer is A. Most galaxies appear to be moving away from each other. Scientists discovered this when looking through very expensive microscopes, and saw that the universe was always growing and expanding, as if exploding from one point and moving outward.
Answer: hypodermis
Explanation:
The very bottom layer of the skin is the hypodermis. It contains the fat cells, or adipose tissue, that insulate the body and help it conserve heat.
God bless you!!
Answer:
The volume of a gas approaches zero as the temperature approaches absolute zero.
Step-by-step explanation:
You may have done a <em>Charles' Law experiment</em> in the lab, in which you measured the volumes of a gas at various temperatures.
You plotted them on a graph, and perhaps you were asked to extrapolate the graph to lower temperatures.
Your graph probably looked something like the one below.
There is clearly an x-intercept at some low temperature.
Inference: The volume of a gas approaches zero as the temperature approaches absolute zero.
Answer:
Granite
Explanation:
The specific heat capacity of a substance, which is denoted by "c", is the amount of heat required to raise the temperature of a particular mass of that substance by 1°C. It is calculated as follows:
c = Q ÷ m∆T
Where;
c = specific heat capacity
Q = amount of heat (J)
m = mass of substance
∆T = change in temperature.
According to this equation and explanation above, a low specific heat capacity means that the rate at which the temperature is raised is slow and vice versa. Hence, from this question, GRANITE with specific capacity of 0.790 J/gK will raise temperature the slowest.
Answer:
Explanation:
No, it is preposterous and possible to expect or to disengage and isolate a basic and neutral compound by 1M NaOH in DCM. Since neutral compounds do not react with NaOH, and NaOH itself is a base so it can't react with another base to yield salt. For that reason, we just need a corrosive element i.e an acid.
So; In DCM, we can't utilize 1M NaOH rather than 1M HCI for isolation and detachment of neutral and basic compounds.
