Antacids work to relieve stomach acids because of which of the following types of reactions?

Chemistry
1 answer:
Anastaziya [24]3 years ago
4 0

<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.

A ball is rolling across the floor. Every 3 seconds it travels 12 meters. Its speed, therefore, is 36 m/s. Is this problem solve
kirill [66]
No because you are supposed to do this

d = t)v
T for time and V for velocity or acceleration so what you do is take the two numbers

D= 3/12 it goes 12 meters every 3 seconds so you devide 12/3
12 \div 3 = 4
So for every second the ball roles 4 meters!
Hope this helps! :)

Write down five things that you personally could do in your day-to-day life to help with the problem of climate change. Write do
beks73 [17]
Before that, we need to know what causes climate change. One of the main reasons are the carbon dioxide released into the atmosphere, it traps heat but allow more heat to enter the earth, therefore climate increases over the years.

1. Set air conditioner to a higher temperature (eg. 25°C) or turn on fans instead.
Operating AC can use a lot of energy, and these energy is produced by burning if fossil fuels which releases carbon dioxide.

2. Take public transports instead of cars. The more private cars there are, the more pollutants it release, these pollutants includes carbon dioxide.

3. Turn off all the lights / electrical appliances when we leave a place. Again, electrical appliances require energy which is produced by burning of fossil fuels that gives out carbon dioxide.

4. Recycle and reuse paper that is only used on one side. Papers are extracted from trees and one main function of trees is to absorb carbon dioxide from the air. If many trees are cut, the amount of carbon dioxide in air would increase.

5. Do the laundry only if you have clothes full for the machine. If the washing machine is not full and you're starting it up, it really uses a lot of energy and water, which all again it triggers the release of carbon dioxide.

you wish to make a 0.161 m hydroiodic acid solution from a stock solution of 3.00 m hydroiodic acid. how much concentrated acid
mestny [16]

5.367 ml of the concentrated acid must be added to obtain a total volume of 100 ml of the dilute solution.

Dilution is defined as the process in which the concentration of a sample is decreased by adding more solvent. The dilution formula is given below.

C₁V₁ = C₂V₂

where C₁ = initial concentration of sample = 3.00 m

V₁ = initial volume of sample

C₂ = final concentration after dilution = 0.161 m

V₂ = total final volume after dilution = 100 ml

Plug in the values to the formula and solve for the volume of the concentrated acid that must be added.

C₁V₁ = C₂V₂

3.00 m (V₁) = 0.161 m (100 ml)

V₁ = 5.367 ml
