In which type of chemical reaction do two or more reactants combine to form one product, only?a. synthesis
b. decomposition
c. single replacement
d. double replacement.

Answers

Answer 1

Answer:

A chemical reaction is defined as the process in which two more reactants are converted to form one or more different product.

The chemical reaction in which two more reactants combine to form one product is a synthesis reaction.

Synthesis reactions are defined as the reaction in which two different atoms or molecules react to form a different compound. Synthesis reactions are exothermic reactions, such that the reactions release energy in the form of heat and light.

One of the most common examples of a synthesis reaction is the formation of sodium chloride. It can be expressed as:

Na (Sodium) + Cl (Chlorine) $\rightarrow$ NaCl (Sodium Chloride)

Thus, the synthesis reaction will result in one different compound or product.

The correct answer is Option A.

Answer 2

Answer: Synthesis is when multiple reactants come together to form one. Decomposition is when one reactant breaks down to form multiple products which are either elements or compounds. Single replacement is when there is an element and a compound and the element switch spots with the other element( metal switch with metal, nonmental with nonmetal, vice versa). The element has to be more reactive than the like element in the compound in order for it to be able to switch. Use the reactivity series to help you with this. Double Replacement is when you have two compounds and like elements switch places.

Answers

Answer:

The volume of the water is 11.5 ml

Explanation:

Volume refers to the space occupied by a fluid.

Usually, a graduated cylinder is used to measure the volume of a fliud. Hence, the volume of the fluid as measured by the graduated cylinder in this case is 11.5 no.

How to convert Gdm-3 to moldm-3

Answers

Since it is still in dm^-3 (which is basically a Litre)

You just need to convert the g into moles using the formula:

moles = mass/molar mass

= 5.6/(39.1+16+1)

= 5.6/56.1

= 0.1 moles

So this makes it 0.1 moles dm^-3
