Answer:
Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the chloride ion Cl–, would also have a concentration of 0.100 M.) The pH is thus –log(0.100) = 1.000.
Explanation:
Answer:
The molar mass of Pb(Cr2O7)2 is 639.2 g/mol.
Answer:
Risk management can be described as the identification and evaluation of certain risks beforehand and the appropriate steps that can be taken to avoid the problematic situations. Risk management is the forecasting of certain risks and the plans made to resist or overcome these risk situations.
An example of a risk management strategy can be a pet owner understanding that he'll have to make major payments for the health of the pet or will have to pay vet bills. In order to save money, the pet owner decided to go for pet insurance beforehand so that any problematic situation can be avoided.
Answer:
option 3
Explanation:
Neon is one of the noble gases. Noble gases don't react with any element because of their stability. Elements of Group 18 in Periodic Table are inert gases.
Answer:
The correct answer is that both molecular motion, pressure and temperature increase as volume reduces.
Explanation:
A reduction in volume changes the molecular motion, temperature and pressure of the system. When the volume of the container decreases, this causes the pressure to increase, the temperature to increase and the molecular motion to increase. This is because a liquid and a solid are incompressible, so by reducing the volume of a gas, the molecules increase their movement as the temperature of the system increases, which is due to the increased pressure applied to reduce the volume of the system.
Have a nice day!
