You need .556M HCL to neutralize that
True
Explanation:
When people conserve electricity, power plants do not need to produce as much electricity because there is less demand for it.
This very correct.
- When electricity is used in a sustainable way, there is little of it consumed.
- Switching off idle electronics would make that amount of electric current to be re-distributed to another place.
- Less coal and fuel would be used and power plants do not need to produce as much electricity.
- Most electricity produced in power plants are often wasted due to idle appliances consuming the bulk of them.
- When these appliances are turned off, less energy is in demand and less will be produced.

Remember that:
number of moles = mass/molar mass
First, we get the molar mass of the nitrogen gas molecule:
It is known the the nitrogen gas is composed of two nitrogen atoms, each with molar mass 14 gm (from the periodic table)
Therefore, molar mass of nitrogen gas = 14 x 2 = 28 gm
Second we calculate the mass of the precipitate:
we have number of moles = 0.03 moles (given)
and molar mass = 28 gm (calculated)
Using the equation mentioned before,
mass = number of moles x molar mass = 0.03 x 28 = 0.84 gm
ANSWER:
Physical chemistry is the branch of chemistry that deals with the physical structure of chemical compounds, the way they react with other matter and the bonds that hold their atoms together. An example of physical chemistry is nitric acid eating through wood.
Mesosaurus lived in freshwater lakes and ponds. Elongated and slim, it measured about 3.3 feet long. The skull and tail were both long and narrow, and the animal probably undulated through the water as it fed on small crustaceans and other prey with its jaws, which were full of long, thin, pointed teeth.
