Answer:

According to the theory, an Arrhenius acid is a substance that gives hydrogen ion, $H^{+}$ (or protons) as the only positively charged ions, when dissociated in water.

Explanation:

What this means is that acids increase the concentration of protons in water to form hydronium ions,as opposed to the idea that there aren't free hydrogen cations floating around in aqueous solution.

The Arrhenius definitions of acidity and alkalinity are restricted to aqueous solutions and refer to the concentration of dissolved ions.

Answer:

An acid is a substance that releases H⁺ in aqueous solution.

Explanation:

There are different acid-base theories, such as Arrhenius, Bronsted-Lowry, Lewis, etc.

According to the Arrhenius theory, an acid is a substance that releases H⁺ in aqueous solution.

HCl(aq) → H⁺(aq) + Cl⁻(aq)

On the other hand, according to the Arrhenius theory, a base is a substance that releases OH⁻ in aqueous solution.

NaOH(aq) → Na⁺(aq) + OH⁻(aq)

The question is incomplete, here is the complete question:

A chemist measures the amount of bromine liquid produced during an experiment. She finds that 766.g of bromine liquid is produced. Calculate the number of moles of bromine liquid produced. Round your answer to 3 significant digits.

<u>Answer:</u> The amount of liquid bromine produced is 4.79 moles.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Given mass of liquid bromine = 766. g

Molar mass of liquid bromine, $(Br_2)$ = 159.8 g/mol

Putting values in above equation, we get:

$\text{Moles of liquid bromine}=\frac{766.g}{159.8g/mol}=4.79mol$

Hence, the amount of liquid bromine produced is 4.79 moles.

Waves transport water in the deep ocean toward the coastlines. True or false

ASHA 777 [7]

Answer:

Most likely true

Explanation:

because the speed of all ocean waves is controlled by gravity, wavelength, and water depth. ... Waves moving through water deeper than half their wavelength are known as deep-water waves. On the other hand, the orbits of water molecules in waves moving through shallow water are flattened by the proximity of the sea surface bottom.

I don’t understand how to solve this and I don’t get ionic equation

Elden [556K]

Explanation:

Spectator ions refers to elements/molecules that do not form part of the reaction. Basically, these elements/molecules are in the same state in the reactant and product side. From the given reaction, Ca and SO4 change their state from aqueous to solid and Na and Cl do not change their state. Therefore, Na and Cl are spectator ions and Ca and SO4 are not spectator ions.

Answer:

The correct option is C.
