What forms when all of the continents on earths surface merge into one massive landform?
Nutka1998 [239]
Continents are generally the largest landforms on Earth. The Eurasian continent, a combination of Europe and Asia (since they are in contact for thousands of miles along the Ural Mountains) is by far the largest landform. Even without including Europe, Asia is the largest of the individual continents.
Hope this helped.

When we react a weak acid with a strong base of equal amounts and concentration, the component of the reaction that will have th
Svetllana [295]

Answer and explanation:

Initially, the pH of the solution will be determined by the dissociation of the weak acid.

Usually, this kind of solution consists of a mixture of weak acid that has not yet reacted and the salt that will be formed by the reaction of the weak acid with a strong base that has been added.

After the dissociation process, the pH will be more affected due to the excess of base in the solution.

Given that the density of air is 14.4, then the vapour of sulphur IV oxide is A. 16 B. 32 C. 64 D. 128
Arisa [49]

Answer:

32

Explanation:

The vapour density of a gas is the number of times a given volume of gas or vapour is as heavy as the same volume of hydrogen at a particular temperature and pressure.

Vapour density = 2 × relative molecular mass of the gas or vapour

Relative molecular mass of SO2 = 32 + 2(16) = 64

Hence;

Vapour density of SO2 = 64/2

Vapour density of SO2 = 32
