Answer : The correct option is, (1)

Explanation :

According to the Arrhenius acid-base concept,

Arrhenius acid is a species that produces H^+ ion in an aqueous solution and Arrhenius base is a species that produces OH^- ion in an aqueous solution.

From the given options, option 1 chemical equation represents the reaction of an Arrhenius acid and an Arrhenius base. In this reaction, HC_2H_3O_2 produces H^+ ion in an aqueous solution and act as an Arrhenius acid, NaOH produces OH^- ion in an aqueous solution and act as an Arrhenius base.

While the other options does not represents the reaction of an Arrhenius acid and an Arrhenius base.

Reaction 2 is an example of combustion reaction.

Reaction 3 is an example of single-displacement reaction.

Reaction 4 is an example of double-displacement reaction.

Hence, the correct option is, (1)

How many grams of silver nitrate will be needed to produce 8.6 g of silver?
konstantin123 [22]

Answer:

13.5g of AgNO3 will be needed

Explanation:

Silver nitrate, AgNO3 contains 1 mole of silver, Ag, per mole of nitrate. To solve this problem we need to convert the mass of Ag to moles. Thee moles = Moles of AgNO3 we need. With the molar mass of AgNO3 we can find the needed mass:

<em>Moles Ag-Molar mass: 107.8682g/mol-</em>

8.6g * (1mol / 107.8682g) = 0.0797 moles Ag = Moles AgNO3

<em>Mass AgNO3 -Molar mass: 169.87g/mol-</em>

0.0797 moles Ag * (169.87g/mol) =

<h3>13.5g of AgNO3 will be needed</h3>

Nitroglycerin is a dangerous powerful explosive that violently decomposes when it is shaken or dropped. The Swedish chemist Alfr
marshall27 [118]

<u>Answer:</u> The balanced chemical equation for the decomposition of nitroglycerin is written below.

<u>Explanation:</u>

Decomposition reaction is defined as the reaction in which a single large substance breaks down into two or more smaller substances.

Every balanced chemical equation follows law of conservation of mass.

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The balanced chemical equation for the decomposition of nitroglycerin follows:

4C_3H_5N_3O_9(l)\rightarrow 12CO_2(g)+10H_2O(g)+6N_2(g)+O_2(g)

By Stoichiometry of the reaction:

1 mole of liquid nitroglycerin decomposes into 12 moles of carbon dioxide gas, 10 moles of gaseous water, 6 moles of dinitrogen gas and 1 mole of dioxygen gas.

Hence, the balanced chemical equation for the decomposition of nitroglycerin is written above.

Convert a speed of 88 m/s to its equivalent in cm/s. <br><br> pls help i don’t get it.
antoniya [11.8K]

Answer:

8800  cm / s

Explanation:

There are 100 cm / m

  so:    88 m/s  * 100 cm / m =   8800 cm/s  

                     ( see how the 'm' cancels out and you are left with cm /s ?)

How many moles are represented by 3.01 - 1023 helium atoms?
Pavlova-9 [17]

Answer:

0.5 mol

Explanation:

Given data:

Number of atoms of He = 3.01 ×10²³

Number of moles = ?

Solution:

Avogadro number:  

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.02 × 10²³ is called Avogadro number.

1 mole = 6.02 × 10²³ atoms

3.01 ×10²³ atoms × 1 mol / 6.02 × 10²³ atoms

0.5 mol
