Which phrase describes a characteristic of an Arrhenius base?

Tom [10]

The phrase that describes a characteristic of an Arrhenius base is that Arrhenius base add hydroxide ions to the solution ( answer C)

Explanation

Arrhenius base is a substance that increases the concentration of OH- in aqueous solution.

The Common Arrhenius base are group 1 and 2 hydroxide such as LiOH, NaOH , Ba(OH)2 among others.

for example NaOH dissociate as follows , NaOH → Na+(aq) + OH- (aq)

Consider the following reaction. Zn(s) 2agno3(aq) --> 2ag(s) zn(no3)2(aq)when 16. 2 g of silver was produced, _____ mole(s) o

Crazy boy [7]

The required amount of silver nitrate to produce 16.2g of silver is 25.48 grams.

<h3>What is the relation between mass & moles?</h3>

Relation between the mass and moles of any substance will be represented as:

n = W/M, where

W = given mass
M = molar mass

Moles of silver = 16.2g / 107.8g/mol = 0.15mol

From the stoichiometry of the given reaction it is clear that, same moles of silver nitrate is required to produce same moles of silver. So 0.15 moles of silver nitrate is required.

Mass of silver nitrate = (0.15mol)(169.87g/mol) = 25.48g

Hence required mass of silver nitrate is 25.48g.

Nat2105 [25]

Answer:

CO is the chemical formula for carbon monoxide.

Co is the chemical symbol for cobalt.

W is the chemical symbol for tungsten.

Be is the chemical symbol for beryllium.

HI is the chemical formula for hydrogen iodide.

Explanation:

Chemical symbols are either written as a single uppercase letter (ex. O) or an uppercase letter and a lowercase letter (ex. Na).

Chemicals can be anything else! For example CO or even somthing like LiIO.
