Answer is: taste bitter.

1) acids taste sour, bases taste bitter.

2) Acids and bases give ions in water solutions, so they conduct electricity.

3) bases have pH greater than 7, acids have pH less than 7.

4) red litmus turn blue whe base is drop on it and blue litmus turn red when acid is drop on it.

In a redox reaction, electrons are transferred from the substance being reduced to the oxidizing agent.
babymother [125]

<u>Answer:</u> The correct answer is from the substance being oxidized to the substance being reduced.

<u>Explanation:</u>

Redox reaction is defined as the reaction in which oxidation and reduction reaction occur simultaneously.

Oxidation reaction is defined as the reaction where an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

X\rightarrow X^{n+}+ne^-

Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes reduction reactions.

Reduction reaction is defined as the chemical reaction where an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

X^{n+}+ne^-\rightarrow X

Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions.

Electrons are transferred from one atom to another in this type of reaction from the substance which is getting oxidized to the substance which is getting reduced.

It can also be said that, electrons are transferred from reducing agent to the oxidizing agent.

Hence, the correct answer is from the substance being oxidized to the substance being reduced.

Using what you have learned about the three forms of writing chemical equations, classify each of the presented equations as eit
suter [353]

Explanation:

Molecular equation: Chemical equation in which molecular formula of reactants and products are written

Complete ionic equation:Chemical equation in which ionic from if reactants reactants and products are written along with spectator ions (ions present on both sides of equation).

Net ionic equation :Chemical equation in which only ions of those reactant are written which giving product without  spectator ions (ions present on both sides of equation).

(a) Ca^{2+}(aq) + SO_4^{2-}(aq)\rightarrow CaSO_4(s)

net ionic equation.

(b) CuSO_4(aq) + 2KOH(aq)\rightarrow Cu(OH))_2(s) + K_2SO_4(aq)

Molecular equation

(c)Ba^{2+} (aq) + SO_4^{2-}(aq)\rightarrow BaSO_4(s)

Net ionic equation.

(d) Ag^+(aq) + NO_{3}^-(aq) + I^-(aq)\rightarrow AgI(s) + NO_{3}^-(aq)

Complete ionic equation

What type of bonding occurs in a sample of pure sodium, ? In other words, how is one sodium atom held to another sodium atom? A.
NeX [460]

Answer:

The answer to your question is B. metallic

Explanation:

Covalent bonding is a bond between two nonmetals and the difference in electronegativity is between 0 and 1.7. Sodium could not have this kind of bond because is a metal.

Ionic bonding is a bond between a metal and a nonmetal and the difference of electronegativity is higher than 1.7. Sodium can have this kind of bond it is necessary one nonmetal.

Metallic, sodium has a metallic bond because this bond is characteristic of metals.

One method used commercially to peel potatoes is to soak them in a solution of NaOH for a short time and then remove them from t
sergij07 [2.7K]

Answer:

b. 2.28 M

Explanation:

The reaction of neutralization of NaOH with H2SO4 is:

2NaOH + H2SO4 → Na2SO4 + 2H2O

<em>Where 2 moles of NaOH react per mole of H2SO4</em>

<em />

To solve the concentration of NaOH we need to find the moles of H2SO4. Using the chemical equation we can find the moles of NaOH that react and with the volume the molar concentration as follows:

<em>Moles H2SO4:</em>

45.7mL = 0.0457L * (0.500mol/L) = 0.02285 moles H2SO4

<em>Moles NaOH:</em>

0.02285 moles H2SO4 * (2moles NaOH / 1 mol H2SO4) = 0.0457moles NaOH

<em>Molarity NaOH:</em>

0.0457moles NaOH / 0.020L =

2.28M

Right option:

<h3>b. 2.28 M</h3>
