Answer:
CO2 soild is "Dry Ice".
Explanation:
if the pressure of liquid CO2 is suddenly released is proportion of the liquid will change to the soild state( become dry ice ) and the remainder will revert in gas..
N2 + 3H2 produces 2NH3 If that is the correct chemical equation.
Reactants
N = 2
H =6
Products
N =2
H= 6
The answer is just one.
Answer:
D. Time and pressure changes dead plant material to peat.
Explanation:
There are four steps in the production of coal: peat, lignite, bituminous and anthracite.
Peat: in this stage dead plants are oxidized to water and carbon dioxide and buried under sediments. The partial decomposition of plant matter due to the absence of oxygen is called peat. There is no factor of time and pressure that changes dead plant material to peat.
Lignite: Peat is subjected to heat, pressure, and time to form lignite.
Bituminous: More pressure in lignite removes all the traces of plant matter and form “soft coal”, bituminous coal.
Anthracite: It is the last stage, in which hard coal forms with the combined pressure and high temperature.
Hence, the correct answer is "D. Time and pressure changes dead plant material to peat."
It takes about 4.186 joules to heat one gram of water by 1 deg Celsius. M
0.50 liters is 500 grams, and you want to hear that by 10C. So, multiply 4.186 by 500*10 the answer is about 4.186*500*10=20930 joules.
If you give 1100 joules per second, it will take 20930/1100=19.027 seconds to supply enough energy.
