A student requires 2.00 L of 0.100 M NH4NO3 from a 1.75 M NH4NO3 stock solution. What is the correct way to get the solution?

Answers

Answer 1

Answer:

To solve this we use the equation,

M1V1 = M2V2

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

1.75 M x V1 = 0.100 M x 2.0 L

V1 = -.11 L

Answer 2

Answer:

Answer : The volume of $NH_4NO_3$ stock solution is, 0.114 L

Solution :

According to the dilution law,

$M_1V_1=M_2V_2$

where,

$M_1$ = molarity of $NH_4NO_3$ solution = 0.100 M

$V_1$ = volume of $NH_4NO_3$ solution = 2.00 L

$M_2$ = molarity of $NH_4NO_3$ stock solution = 1.75 M

$V_2$ = volume of $NH_4NO_3$ stock solution = ?

Now put all the given values in the above law, we get the volume of $NH_4NO_3$ stock solution.

$(0.100M)* (2.00L)=(1.75M)* V_2$

$V_2=0.114L$

Therefore, the volume of $NH_4NO_3$ stock solution is, 0.114 L

Cold packs are used to treat minor injuries. Some cold packs contain NH4NO3(s) and a small packet of water at room temperature before activation. To activate this type of cold pack, the small packet must be broken to mix the water and NH4NO3(s). The temperature of this mixture decreases to approximately 2°C and remains at this temperature for 10 to 15 minutes.State the direction of heat flow that occurs when the activated cold pack is applied to the body.
Identify both types of bonds in the NH4NO3(s).

Answers

These types of reactions are called endothermic reactions. This is when the system absorbs the heat from the surrounding. In this case, the system is the chemical reaction and the environment is the direct vicinity of the chemical reaction. You notice that the pack becomes cold because heat from the surrounding is being absorb.

The bonds involved in this substance includes ionic bonding and polar covalent.

Find the normality of a solution containing 20g of H2SO4(sulfuric acid) per 500ml of solution. The molar mass of H2SO4 is 98 g/eq. H2SO4 has two replaceable H+.

Answers

H2SO4 ------------- > 2 H⁺ + SO₄²⁻

g/eq = molar mass / number of H⁺

g/eq = 98 / 2

= 49 g/eq

Volume in liters = 500 mL / 1000 => 0.5 L

N = 20 / 0.5 x 49

N = 20 / 24.5

= 0.816 N

hope this helps!

Which chemical equation represents the reaction of an Arrhenius acid and an Arrhenius base?(1) HC2H3O2(aq) + NaOH(aq) --> NaC2H3O2(aq) + H2O(l)
(2) C3H8(g) + 5 O2(g)--> 3 CO2(g) + 4 H2O(l)
(3) Zn(s) + 2 HCl(aq)--> ZnCl2(aq) + H2(g)
(4) BaCl2(aq) + Na2SO4(aq) --> BaSO4(s) + 2 NaCl(aq)

Answers

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)

The chemical equation that represents the reaction of an Arrhenius acid and an Arrhenius base is 1) HC2H3O2 (aq) + NaOH (aq) ---> NaC2H3O2 (aq) + H2O (I)
