<span>he specific heat capacity of liquid water is 4.186 J/gm K.</span>
Answer:
709415.584 g
Explanation:
This is a heat capacity problem. We use the formula below to calculate.
Q=mcΔT
where Q is the quantity of heat
m is the mass of substance
ΔT is the change in temperature of substance( T2-T1).
Q= 9.5MJ = 9.5*10^(6}J
C.P = 30.8J/(K.mol)
temperature of sodium increases by 10°C which means our final temperature in kelvin T2 will be 510K
initial temperature T1= 500K
m= Q/[c (T2-T1)]
m= 9.5*10^(6}/ {30.8(510-500)]
m= 30844.156 mol of Na
Converting to grams we multiply by the molar mass of Na.
molar mass of Na = 23
mass of Na= 30844.156 *23
=709415.584 g
The correct answer is 1.1 moles
Answer:
Hi,
The assembling of proteins starts with the attachment of m RNA to the ribosomes in the cytoplasm. Each of the ribosome read the code in the m RNA from “start” to “ stop” choosing the specific amino acid building block and removing the unwanted growing protein. The ribosome performs this process in 0.02 seconds and with this rate it is possible for the cell to perform assembling of small protein such as insulin.
Best wishes!
Yes they do. But a very small kinetic energy. They vibrate in fixed positions
