In industrialized states every tenth adult suffers daily, and every third occasionally, from heartburn. In Germany almost ten million people are affected by this disease. Helpful medicines against heartburn are the so-called ‘antacids’.

Antacids bound acids against an over-acidification of the stomach. The stomach acid contains hydrochloric acid (HCl, dissolved in water), which reacts with the antacid to form water, carbon dioxide and the corresponding salt. Generally, antacids are carbonates. Very common is ‘Bullrichs salt’, which uses sodium hydrogen carbonate as active ingredient. A single dose of an antacid is to be chosen in a way that it will react with two grams of hydrochloric acid. You are to formulate the instruction leaflet for a pharmaceutical company, which sells calcium carbonate (CaCO3) as an antacid. The dosing instruction says that in case of heartburn, one tablet with sufficient water is to be ingested.

But the specification, how many grams of calcium carbonate one tablet contains, is still missing…

Answer 1

Answer:

Antacids are medicines that counteract (neutralise) the acid in your stomach to relieve indigestion and heartburn. They come as a liquid or chewable tablets and can be bought from pharmacies and shops without a prescription.

When energy decreases what happens to particle motion?

Answers

Answer:

When a substance is cooled, its internal energy decreases: the movement of its particles decreases. bonds between particles form when a substance condenses or freezes, or sublimes to form a solid from a gas. What is called energy? Energy is the capacity of a physical system to do work.

Which of the following lists electromagnetic radiations from lowest to highest energy?
Your answer:
radio waves, microwaves, ultraviolet radiation, visible light
microwaves, radio waves, visible light, X-rays
radio waves, infrared radiation, visible light, ultraviolet radiation
gamma radiation, infrared radiation, visible light, X-rays

Answers

Answer:

Highest wavelength : radio waves

So lowest energy: radio waves

Hence order is:

radio waves < microwaves < IR waves < visible light < ultraviolet radiation < X-rays < gamma rays

Calculate the ionization constant of each reaction. hcl (aq) + h2o (l) equation h3o+ (aq) + cl- (aq); [hcl] = 16.9m, [h3o+] = 13.3m, [cl-] = 7.4mka =

Answers

The ionization constant from the reaction as shown in the calculation is 5.8.

What is the ionization constant?

The term ionization constant refers to the extent to which the acid is ionized in solution. It is calculated from;

Ka = [H3O^+] [Cl]/[HCl]

Thus when we substitute the values;

Ka = 13.3 * 7.4/ 16.9

Ka = 5.8

The ionization constant from the reaction as shown in the calculation is 5.8.

The pressure of x ml of a gas was increased from 2 atm to 4 atm at constant temperture. what will be the new volume?

Answers

The new volume of the gas given the data from the question is  1/2X mL

Data obtained from the question

Initial volume (V₁) = X mL

Initial pressure (P₁) = 2 atm

New pressure (P₂) = 4 atm

New Volume (V₂) = ?

How to determine the new volume

The new volume of the gas can be obtained by using the Boyles’ law equation as illustrated below:

P₁V₁ = P₂V₂

2 × X = 4 × V₂

2X = 4V₂

Divide both side by 4

V₂= 2X / 4

V₂ = 1/2X mL

In this case, among the list of components given, the abiotic factors are water, rock, soil, and sun.

What is an abiotic factor?

An abiotic factor is a non-living part of an ecosystem that shapes its environment.

Biotic and abiotic factors make up a community via interaction.

Biotic factors are considered living things (having "life") while abiotic factors are simply non-living things.

Hence, in this case, among the list of components given, the abiotic factors are water, rock, soil, sun
