The kinetic theory states that potential energy in a gas is low but has high potential energy and they move around fast, Say in a solid it has more potential energy but less kinetic.
Answer : Salt is more soluble in an acidic solution than in an neutral solution.
Explaination : In an acidic solution molecules of salt are assaociated with hydrogen bonding whereas in neutral solutions it molecules are not assaociated with hydrogen bonding. Acidic solution is a type of solution which has higher concentration of hydrogen ions than water is called acidic solution for ex: water.
Neutral solution is a solution which has a pH of 7,it is neither acidic nor basic but it is middle so that is called neutral solution.
Answer: 100.3 mmHg
Explanation:
Given that:
Volume of nitrogen gas V = 4.200 L
Temperature T = 21°C
Convert Celsius to Kelvin
(21°C + 273 = 294K)
Pressure P = ?
Number of moles of gas = 0.02300
Molar gas constant R is a constant with a value of 0.0821 atm L K-1 mol-1
Then, apply ideal gas equation
pV = nRT
p x 4.200L = 0.02300 moles x (0.0821 atm L K-1 mol-1 x 294K)
p x 4.200L = 0.555 atm L
p = 0.555 atm L / 4.200L
p = 0.132 atm
Now, convert pressure in atm to mmHg
If 1 atm = 760 mmHg
0.132 atm = (0.132 x 760) = 100.3 mmHg
Thus, 100.3 mmHg of pressure is required
Explanation:
Reactants can be referred to as starting materials for a chemical reaction. They undergo a change to form products. Reactants are usuallyconsumed in the reaction process.
Reactants are written at the left side before the arrow sign in a reaction.
Products are the ending materials of a reaction. They are what is left after the reactants has been consumed.
Prpducts are written on the right side after the arrow sign in a reaction
Basically, a reaction is given as;
Reactants --> Products
A + B --> C + D
A and B are reactants and C and D are products
In the reaction;
“carbon plus oxygen makes carbon dioxide”
C + O2 --> CO2
The reactants are; C and O2.
The product is CO2
