The reaction is a synthesis reaction.

<h3>What are synthesis reactions?</h3>

Synthesis reactions are one of the numerous reactions in chemistry. These kinds of reactions involve the combination of two atoms of different elements resulting in the formation of new compounds.

Synthesis reactions are sometimes referred to as combination reactions, simply because they have to do with the combination of two or more atoms of different elements into a single compound.

The different elements that combine are referred to as the reactants while the result of the combination is known as the product.

For example: A + B --> AB

In the illustrated reaction, N2 combined with H2 to form NH3. N2 and H2 gases are the reactants while NH3 is the only product formed from the two reactants.

This is a good example of a synthesis/combination reaction.

This is a sign of a chemical reaction that involves a new color being created during the reaction.
svetoff [14.1K]
Hey there!


When two or more substances combine, they create one or more new substances, which sometimes have different molecular structures from the original substances, meaning they absorb and radiate light in different ways, leading to a color change.


Hope this helps! :)

Antacids work to relieve stomach acids because of which of the following types of reactions?
Anastaziya [24]

<u>Answer:</u> The correct answer is Option B.

<u>Explanation:</u>

Decomposition is a type of chemical reaction in which larger compound breaks down into two or more smaller compounds.

AB\rightarrow A+B

Double displacement reactions is defined as the chemical reaction in which exchange of ions takes place.

AB+CD\rightarrow AD+CB

Synthesis reaction is a type of reaction in which two or more smaller compounds combines to form a single large compound.

A+B\rightarrow AB

Single displacement reaction is a type of reaction in which a more reactive metal displaces a less reactive metal from its chemical reaction.

A+BC\rightarrow AC+B

In stomach, an acid is present known as hydrochloric acid and to neutralize its effect, antacid is taken which has CaCO_ as a component.

The reaction between HCl and CaCO_3 is a type of neutralization reaction and it is a type of double displacement reaction.

The equation between the two follows:

CaCO_3+HCl\rightarrow CaCl_2+H_2O+CO_2

Hence, the correct answer is Option B.

What is the simplest formula of a compound if a sample of the compound contains 0.221 mol X, 0.442 mol Y, and 0.884 mol Z? chemP
Gnoma [55]

Answer:

XY₂Z₄

2.35 mol Z

Explanation:

A sample of the compound contains 0.221 mol X, 0.442 mol Y, and 0.884 mol Z. We can find the simplest formula (empirical formula) by <em>dividing all the numbers of moles by the smallest one</em>.

X: 0.221/0.221 = 1

Y: 0.442/0.221 = 2

Z: 0.884/0.221 = 4

The simplest formula is XY₂Z₄.

The molar ratio of X to Z is 1:4. The moles of Z in a sample that contained 0.588 moles of X is:

0.588 mol X × (4 mol Z/1 mol X) = 2.35 mol Z
