Answer:
constant
Explanation:
A constant is a number with a fixed value in a specific mathematical context
Answer:
It helps the body remove heat through sweating.
Explanation:
When the weather is hot, the body tries to keep cool by sweating. The high specific heat capacity means that the body doesn't have to lose much water to stay cool.
The high specific heat capacity of water doesn’t heat the body, but it slows down the rate of heat loss when the weather is cool.
B is wrong. The body uses glucose, not water, as an energy source.
C is wrong. The high specific heat capacity of water is not connected with the body's ability to store it.
D is wrong. The high specific heat capacity of water doesn't heat the body, but it slows the rate at which it cools.
Answer:
False
Explanation:
Always add acid to the water, it dilutes the acid the other way around.
Answer:
The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids.
Answer: A mass of 124457.96 g ammonia is produced by reacting a 450 L sample of nitrogen gas at a temperature of 450 K and a pressure of 300 atm.
Explanation:
Given: Volume = 450 L
Temperature = 450 K
Pressure = 300 atm
Using ideal gas equation, moles of nitrogen are calculated as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = tempertaure
Substitute values into the above formula as follows.

According to the given equation, 1 mole of nitrogen forms 2 moles of ammonia. So, moles of ammonia formed by 3654.08 moles of nitrogen is as follows.

As moles is the mass of substance divided by its molar mass. So, mass of ammonia (molar mass = 17.03 g/mol) is as follows.

Thus, we can conclude that a mass of 124457.96 g ammonia is produced by reacting a 450 L sample of nitrogen gas at a temperature of 450 K and a pressure of 300 atm.
