Answer: Option (C) is the correct answer.

Explanation:

Carbon element has 4 valence electrons and it has a unique ability to combine with different elements.

Also, carbon element is the basis of life as organic molecules are responsible for life an individual.

And, every organic compound contains carbon atom as the central element.

Also, carbon has the ability to form long chains which is known as catenation property.

Thus, we can conclude that carbon element is able to combine in many ways with different elements and is therefore considered the basis of life.

Write a hypothesis about whether radiation has the same impacts on coastal areas, forest areas, and desert areas.

Natasha2012 [34]

Radiation has different intensity of impact depending on the area which they are experienced. Excessive amounts of radiation cause abnormalities in the growth of living things, humans, animals, and plants. The intensity of the damage in forest and coastal areas is higher compared to desert areas since more wildlife are present in the two former areas.

A student wishes to prepare 2.00 Liters of a 0.100 M KIO3 (molecular weight 214). The proper procedure is to weigh out:_____

Vsevolod [243]

Answer:

Explanation:

A. Wrong

The volume of water in 2kg of water might not be 2L

D is correct.

Firstly, we need to know that the number of moles equals the mass over the molar mass. Doing this with the particular data in tie question would give 0.2M.

Hence it is essential that what we get is 0.2M in one liter. But since we are gunning for 2L, adding more than one liter of water would affect the molarity, that is why it now will be 0.1M in 2L

C is wrong

What is prepared here is 0.05M in 2L

B is wrong

What is needed is actually 2L of water and not the total volume of both being 2L

E is wrong

Aqueous potassium phosphate was mixed with aqueous magnesium chloride, and a crystallized magnesium phosphate product was formed

scoray [572]

<u>Answer:</u> The other product formed is potassium chloride.

<u>Explanation:</u>

Precipitation reaction is defined as the chemical reaction in which an insoluble salt is formed when two solutions are mixed containing soluble substances. The insoluble salt settles down at the bottom of the reaction mixture.

The chemical equation for the reaction of potassium phosphate and magnesium chloride follows:

$2K_3PO_4(aq.)+3MgCl_2(aq.)\rightarrow Mg_3(PO_4)_2(s)+6KCl(aq.)$

By Stoichiometry of the reaction:

2 moles of aqueous solution of potassium phosphate reacts with 3 moles of aqueous solution of magnesium chloride to produce 1 mole of solid magnesium phosphate and 6 moles of aqueous solution of potassium chloride.

Hence, the other product formed is potassium chloride.
