Answer:
1.75 atm
Explanation:
When the pressure that a gas exerts on a sealed container changes from 1.75 atm to 2.64 atm, the temperature changes from 315 K to 475 K.
(2.64 atm) x (315 K / 475 K) = 1.75 atm
The pressure and temperature of a gas in a sealed container are directly proportional. An increase in temperature would imply that the pressure also increased.
Answer:
ash, smoke, carbon dioxide are obtained from burning waste
<span>They both have the same number of atoms. The molar mass of CO2 is 44.01 g/mol.</span>
Answer:
B
Explanation:
The debris of marine organisms such as corals, shells, and algae accumulate in the bottom of marine waters and accumulate with sediments. This debris is made up of calcium carbonate and over time the pressure and temperatures after sedimentation layers result to formation of limestone that transforms the calcium carbonate to the form of calcite.
The concentration of a cell is generally 0.15 M (0.9 % NaCl)
As given the solution has concentration = 200mm = 0.02 M
This concentration of solution is less than the concentration of cell
Hence solution is hypotonic (less concentration) and cell will be hypertonic
