Answer:
Chemical science arises in the seventeenth century from the studies of alchemy popular among many of the scientists of the time. The basic principles of chemistry are considered to be collected for the first time in the work of the British scientist Robert Boyle: The Skeptical Chemist (1661).
Answer: the answer is a i suppose
Explanation:
Answer:
reduces
Explanation:
According to Boyle's law, when the pressure of a gas increases at constant temperature the volume reduces.
Boyle's law states that "the volume of fixed mass of a gas is inversely proportional to the change in pressure if the temperature is constant".
- It suggests that at constant temperature, if pressure increases, temperature reduces.
Mathematically, it is expressed as;
P1 V1 = P2 V2
P and V are pressures
1 and 2 are initial and finals state.
The question is: To neutralize 20ml of 0.1M HCl solution, 10ml of NaOH solution of concentration x mol/l is required. What is the value of x?
Answer: The value of x is 0.2 M.
Explanation:
Given: 
= 20 mL, 
= 0.1 M
= 10 mL, 
= x
Formula used is as follows.
Thus, we can conclude that the value of x is 0.2 M.
