Answer:
Four (4) hydrogen atoms
Explanation:
C=C-C(triple bond)C
only four hydrogen atoms can bond with the vacant space
Explanation:
cannot be present in appreciable concentrations in a solution that is strongly acidic in nature. A weak acid is a complex that consists of hydrogen bound to an anion that does not dissociate well in solution comparing to a strong acid which dissolves completely to an anion. Therefore, cannot be present in appreciable concentrations in a solution that is strongly acidic in nature.
Atomic mass of sodium is 22.9 g/mol
atomic mass of chloride is 35.45 g/mol
sodium chloride is 22.99 + 35.45= 58.44 g/mol
Answer:
The pressure of the gas will increase.
Explanation:
This concept of change in state properties of gas, when compressed in a moveable piston-cylinder assembly, can be explained by using Boyle's law
Boyle's law states that the pressure of a given mass of gas is inversely proportional to its volume given that temperature remains constant.
Following this law, when the gas in the container is compressed to a smaller volume, the pressure will go up.
This is also because the gas is not free to move about without frequent collisions with itself and the walls of the container, due to the resulting smaller space after compression. Therefore, the force it exerts on the walls of the container and the frequency of collision are more.
