Answer:
Explanation:
One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid. Air masses are classified on weather maps using two or three letters. A lowercase letter describes the amount of moisture in the air mass: m for maritime (moist) and c for continental (dry).
Answer:
Crude oil is separated by fractional distillation. Crude oil is heated to vaporize the different hydrocarbons in a tank which is cool at the top and hot at the bottom. The vapours then rise and the different hydrocarbons condense at their specific boiling points, allowing them to be separated.
Lighter products, such as butane and other liquid petroleum gases (LPG), gasoline blending components, and naphtha, are recovered at the lowest temperatures. Mid-range products include jet fuel, kerosene, and distillates (such as home heating oil and diesel fuel).
The type of substance that is most likely to contain a covalent bond is ONE THAT IS COMPOSED OF ONLY NON METALS.
Covalent bond is a type of chemical bond in which electron pairs are shared among the participating elements in order to achieve the octet form. Covalent bond is usually found among non metals.
Answer:
The answer to your question is 1) 0.037 M 2) 0.32 M 3) 0.096 M
Explanation:
a) 125 ml of 0.251 M HCl
-Calculate the moles of HCl
Molarity = moles/volume
-Solve for moles
moles = Molarity x volume
-Substitution
moles = 0.251 x 0.125
= 0.0314
-Calculate the new molarity
Molarity = 0.0314/ (0.125 + 0.250)
-Simplification
Molarity = 0.014/0.375
-Result
Molarity = 0.037 M
2.-
445 ml of 0.499 M of H₂SO₄
-Calculate the number of moles
moles = 0.499 x 0.445
moles = 0.222
-Calculate the new molarity
Molarity = 0.222/(0.445 + 0.25)
Molarity = 0.222/0.695
Molarity = 0.32
3)
5.25 l of HCO₃ 0.101 M
Calculate the number of moles
moles = 0.101 x 5.25
moles = 0.53
-Calculate the Molarity
Molarity = 0.53 / (0.25 + 5.25)
Molarity = 0.53 / 5.5
Molarity = 0.096
