Answer:

The error of an experiment is the difference between the experimental and accepted values. If the experimental value is less than the accepted value, the error is negative. If the experimental value is larger than the accepted value, the error is positive.

Suppose you used 0.5 M NaOH to titrate your vinegar sample instead of 0.1 M. What effect does the concentration of base added ha
laiz [17]

Answer: the reliability will be worse

Explanation:

Suppose we used 0.5 M NaOH to titrate our vinegar sample instead of 0.1 M.

Now by using 0.5M instead of 0.1M we are increasing the concentration of NaOH,

We know that  the moles used = Volume x concnetration.

so for the same no of moles, if the concentration increases, the volume decreases.

Hence it will consume less NaOH.

now Since the volume decreases, the titration volume of less number will increase the % error.

Therefore the reliability will be worse.

A hydrocarbon of pentane has two isomeric forms—n-pentane and iso-pentane. The molecular formula of the n-pentane is C5H12. Pred
Monica [59]
An iso pentane is an isomeric form of n-pentane. Isomers have same molecular formula but differ in the atomic arragement projected in 3D and the arrangement of atoms primarily resulting to a different set of properties. In this case, isopentane also has a molecular formula of an alkane <span>C5H12</span>

Which is the coal with the highest energy available per unit to burn: lignite, subbituminous, bituminous, or anthracite?
olya-2409 [2.1K]

Answer:

Anthracite

Explanation:

Anthracite produce highest amount of energy than other. It contain 86-97 percent carbon. Bituminous coal contain 45-86 percent carbon.

Subbituminous cola have 35-45 percent carbon while lignite contain 25-35 percent carbon.

Coal is source of many organic materials. It is fossil fuel and form after long period decay of plants. It is formed when trees are buried under earth

about 500 million years ago. The chemical and bacterial reactions take place and plant wood converted into the peat.

Than because of high temperature and pressure inside the earth peat is converted into the coal.

Through other processes it is than used to make the fuels such as coke. coal tar and coal gas.

Coal tar is the source of many organic compounds which are separated through fractional distillation.

About 80% of coal in Pakistan is used to bake the bricks and also used in lime kilns and for domestic purpose.
