The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.

What is a Chemical reaction?

Chemical reaction refers to reaction that take place between reacting substances in which the chemical substances are transformed to products.

When the concentration of the reactants increases, more molecules tend to interact with each other in order to form new compounds, and the rate of reaction increases. When the concentration of the reactants reduces, there are little of that molecule present, and the rate of reaction decreases

Therefore, The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.

If a 28.0 L balloon with a temperature of
25 °C is cooled in a refrigerator, what will
be the volume of the balloon be when it
reaches 5 °C?

Answers

Answer:

5.6 L

Explanation:

We can apply Charles' Law here since our pressure is constant (will not change inside the refrigerator) and we are relating change in volume with change in temperature:

V₁ / T₁ = V₂ / T₂ where V₁ and T₁ are initial volume and temperature, and V₂ and T₂ are final volume and temperature. Let's plug in what we know and solve for the unknown:

28.0 L / 25 °C = V₂ / 5 °C => V₂ = 5.6 L

5.6 L is our new volume (at 5 °C).

How many atoms are in 1.00 moles of Calcium (Ca)?

Answers

Answer:

One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore number of atoms in 1.00 moles of Calcium (Ca) are 6.022×10²³ atoms.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. Mole is inversely proportional to molar mass.

Mathematically,

mole =given mass ÷ molar mass

Number of atoms = moles ×6.022×10²³ atoms

Substituting the values in above formula we get

Number of atoms = 1 ×6.022×10²³ atoms

Number of atoms 1 mole of calcium = 6.022×10²³ atoms

Therefore, number of atoms in 1.00 moles of Calcium (Ca) are 6.022×10²³ atoms.

A neutralization reaction occurs between sodium hydroxide and sulfurous acid. Complete the equation below for the neutralization reaction that ocurs during the titration

Answers

Answer:

2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃

Explanation:

When a base as sodium hydroxide (NaOH) reacts with an acid as sulfurous acid (H₂SO₃), the H⁺ of the acid will produce with the OH⁻ of the base H₂O. Te complementary ions will produce the respective salt (Na₂SO₃):

NaOH + H₂SO₃ → H₂O + Na₂SO₃

To balance the sodiums:

2NaOH + H₂SO₃ → H₂O + Na₂SO₃

And the hydrogens:

2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃

And this is the complete reaction for this neutralization reaction.

In a lab, students measured the mass of an unknown metal to be 46.4g The metal sample releases 769 J when it is cooled from 101.0°C to 30.00 "C, the

Lead
Copper
Mercury
Silver

Answers

From Q = mcΔΤ, the specific heat capacity, c, of the metal that was cooled is c = Q/mΔT = (-769 J)/(46.4 g)(30.0 °C - 101.0 °C) = 0.233 J/g °C. From the table, it appears that this is the specific heat capacity of silver. So, the metal is most like silver.

Note: The value for Q was written as a negative value in the equation as heat energy was given off by the metal when the metal was cooled (from the metal’s point of view, it’s losing heat energy).

Explanation:

Turgor pressure is the pressure forced or in other words, exerted onto the cell wall of the plant. It's caused by the movement of water into the cell. This causes the water to rush and burst into the cell, which increases the pressure onto the cell wall. Due to that, cell swells up, which helping the plant to stand upright and straight.

How many moles of calcium nitrate would react with 4.55 moles of chromium (III) sulfate to produce calcium sulfate and chromium(III) nitrate?

Answers

Answer:

13.65 moles

Explanation:

The equation of the reaction is;

3Ca(NO3)2 + Cr2(SO4)3 = 3Ca(SO4) + 2 Cr(NO3)3

4.55 moles of chromium (iii) sulfate reacts with calcium nitrate

The mole ratio of Chromium (iii) sulfate to calcium nitrate is 1: 3

Therefore; the moles of calcium nitrate will be given by

 = (4.55/ 1)×3

= 13.65 moles

Hence; 13.65 moles of calcium nitrate would react with 4.55 moles of Chromium (iii) sulfate.

Create the Equation: How many grams of Aluminum Chloride would be made from 42.7 L of Chlorine gas at STP reacting with 50.0 g of Aluminum?

Answers

Answer: 169.3 g of [tex]AlCl_3[/tex] will be produced

Explanation:

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]

moles of [tex]Al[/tex]

[tex]\text{Number of moles}=\frac{50.0g}{27g/mol}=1.85moles[/tex]

moles of [tex]Cl_2[/tex]

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1 atm (STP)  

V = Volume of gas = 42.7 L

n = number of moles = ?

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]273K[/tex]   (at STP)

[tex]n=\frac{PV}{RT}[/tex]

[tex]n=\frac{1atm\times 42.7L}{0.0820 L atm/K mol\times 273K}=1.90moles[/tex]

[tex]2Al+3Cl_2\rightarrow 2AlCl_3[/tex]

According to stoichiometry:

3 moles of [tex]Cl_2[/tex] reacts with = 2 moles of aluminium

Thus 1.90 moles of [tex]Cl_2[/tex]reacts with=  [tex]\frac{2}{3}\times 1.90=1.27[/tex] moles of aluminium  

Thus [tex]Cl_2[/tex] is the limiting reagent as it limits the formation of product.

As 3 moles of [tex]Cl_2[/tex] give =  2 moles of [tex]AlCl_3[/tex]

Thus 1.90 moles of [tex]Cl_2[/tex] give =[tex]\frac{2}{3}\times 1.90=1.27moles[/tex]  of [tex]AlCl_3[/tex]

Mass of [tex]AlCl_3=moles\times {\text {Molar mass}}=1.27moles\times 133.34g/mol=169.3g[/tex]

Thus 169.3 g of [tex]AlCl_3[/tex] will be produced from the given masses of both reactants.
