Which pH value represents a solution with the lowest OHM<br> ion concentration?
Arlecino [84]

pH value 1 represents a solution with the lowest OH⁻ion concentration.

<u>Explanation:</u>

pH is given by the expression as the negative logarithm to the base 10 of the concentration of hydrogen ions.

pH = -log₁₀[H⁺]

If the pH is lower than 7, pH < 7 then it is acidic

If the pH = 7, then it is neutral

If the pH > 7, then it is basic

If pH is 1 then the solution is showing mostly acidic character,which is least basic in its character.

So if the pH is 1, which is most acidic and least basic solution that is lowest OH⁻ ion concentration.

1.What does the Law of Conservation of Energy tells us?
lorasvet [3.4K]
1. Energy can neither be created or destroyed.
2. Conduction. Putting a pot of water on a hot burner. Convection. Putting your wet shoes over an air vent to dry them quicker. Radiation. Sitting in front of the fire to warm your hands up.
3. renewable sources can be used again and again, but non renewable sources cannot.
4. I would recommend solar energy. I think solar energy should be considered because solar energy can be reused, and also because they can use it to power their houses and they wouldn't need fossil fuels to do so.
5. Turn off the lights and open the windows during the day and if something is left plugged into the wall and it is not being used, unplug it.

hope I could help!

What is an advantage of using natural gas rather than a coal burning power plant?
Olenka [21]

Answer:

I hope it helps u

Explanation:

The advantages of using natural gas rather than coal are the following,

  • Natural gas is present in large amount than coal.
  • Natural gas is less costly than other fossil fuel sources of energy.
  • It increases security by decreasing dependence.
  • Natural gas is more environmentally friendly.
  • Natural gas is much safer to store.
  • It is reliable.
  • Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil.
  • Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas-power plant compared with emissions from a typical new coal plant.

A chemical reaction yields 3 moles of lithium hydroxide (LiOH). How many grams of
grin007 [14]

72g

Explanation:

Given parameters:

Number of moles of LiOH = 3moles

Unknown:

Mass of LiOH = ?

Solution:

A mole of  substance is a unit used to make quantitative measures in chemistry.

It is the amount of substance that contains the avogadro's number of particles.

The mole is related to mass using the expression below;

    Mass of a substance = number of moles x molar mass

Molar mass of LiOH = 7 + 16 + 1 = 24g/mol

 Mass of LiOH = 3 x 24 = 72g
