What do you notice is different about the arrangement of the H 2 O molecules in solid form compared to the arrangement of molecu

Nonamiya [84]

Answer:

when the water is frozen, the molecules are tight and bunched together because its a solid. Although that the molecules seem to be tight, it does not meant that the molecules are not moving. The molecules in H 2 O solid form makes them move fast as in vibration. If the H 2 O was in liquid form, the molecules would be spread out and there would be plenty of room to move. But if the H 2 O is a gas, the molecules are even more loose that the liquid and they do whatever they choose to.

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 mass of 7.00 moles of H2O2

____ [38]

Answer:

0.206 mol H₂O₂

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

Reading a Periodic Table
Using Dimensional Analysis

Explanation:

<u>Step 1: Define</u>

7.00 moles H₂O₂

<u>Step 2: Identify Conversions</u>

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H₂O₂ - 2(1.01) + 2(16.00) = 34.02 g/mol

<u>Step 3: Convert</u>

<u /> $7.00 \ g \ H_2O_2(\frac{1 \ mol \ H_2O_2}{34.02 \ g \ H_2O_2} )$ = 0.205761 mol H₂O₂

<u>Step 4: Check</u>

<em>We are given 3 sig figs. Follow sig fig rules and round.</em>

0.205761 mol H₂O₂ ≈ 0.206 mol H₂O₂
