An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons.
<h3>What is an Arrhenius acid?</h3>
An Arrhenius acid increases the number of ions in the water.
According to the Arrhenius theory, a substance which has hydrogen atom and can easily give hydrogen ion or proton in its aqueous solution is called as Arrhenius acid.
For example, when hydrochloric acid is dissolved in water, it forms chloride ion () and hydronium ion ().

Answer:
Use a commercially produced charcoalfilter
Explanation:
Water found in streams, depressions and ground water must be contaminated with pathogenic microorganisms. The methods of disinfection using iodine or bleach or boiling the water for about two minutes and then filtering it with a clean cloth will effectively remove the microorganisms.
However, charcoal filters do not eliminate microorganisms from water hence this method is not acceptable in this case.
16 grams.
Looking at the reaction equation, it's evident that for each mole of HBr
consumed, 1 mole of CO2 will be produced. So let's calculate the molar mass
of HBr and CO2 first.
Atomic weight hydrogen = 1.00794
Atomic weight bromine = 79.904
Atomic weight carbon = 12.0107
Atomic weight oxygen = 15.999
Molar mass HBr = 1.00794 + 79.904 = 80.91194 g/mol
Molar mass CO2 = 12.0107 + 2*15.999 = 44.0087 g/mol
Moles HBr = 30 g / 80.91194 g/mol = 0.370773461 mol
Grams CO2 = 0.370773461 mol * 44.0087 g/mol = 16.317258 g
Rounding to 2 significant digits gives 16 grams.
Answer:
0.67 cm³
Explanation:
We can solve this problem by using the <em>definition of density</em>:
We can rearrange the equation and isolate volume:
As we are given both <em>the mass and the density</em>, we can now<u> calculate the volume</u>:
- Volume = 13 g ÷ 19.3 g/cm³
