2. Circle all of the following that change with the temperature of a reaction.

3. Draw an arrow on this graph of the Arrhenius equation that shows where you would find ln A (log of the frequency factor).

4. If the slope of the line in the graph above is -350 K, what is the value of Ea (in J/mol)?

The mass percentage of the solution that we have in the question is  5 g.

Percent w/w (weight/weight) concentration is a way to express the concentration of a solute in a solution as a percentage by mass. It represents the mass of the solute in grams per 100 grams of the solution.

Percent w/w concentration is commonly used in industries such as pharmaceuticals, food and beverage, and cosmetics to measure the concentration of active ingredients or additives in their products.

We know that;

%w/w = weight of the solute/Weight of the solution

Let the weight of the solute be x

1 = x/500 * 100/1

1 = 100x/500

500 = 100x

x = 5 g

Competition as the owl and snakes are both preying on the mice in a forest so they are both competing for the food source of mice.

Animals that are carnivores (and some omnivores) must hunt their food. These hunters are called predators, and the animals or insects they hunt are called prey.

Owls are an example of predator organisms. They feed on smaller organisms such as mice. The mice, therefore, serve as prey for the owls.

Hence, competition as the owl and snakes are both preying on the mice in a forest so they are both competing for the food source of mice.

If this scenario is used as a model for genetic information, then the statement 'the manual is a chromosome' is correct. A chromosome contains linear arrangements of genes.

A chromosome can be considered as a long nucleotide sequence that contains linear arrangements of genes.

In a chromosome, each DNA strand contains a nucleotide sequence that may encode proteins (i.e., different genes).

A chromosome can then be considered as manual containing instructions (genes) for how to build a variety of structures using a set of interlocking bricks (nucleotides).

The temperature of the container containing the 4.47 g of Ar is 358.16 K

Mole = mass / molar mass

Mole of Ar = 4.47 / 40

Mole of Ar = 0.11175 mole

The temperature of the container can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

Divide both side by nR

T = PV / nR

T = (1.24 × 2.65) / (0.11175 × 0.0821)

Taking into account the reaction stoichiometry, 90.33 grams of SO₂ are formed when 124 grams of iron(II) sulfide are used.

In first place, the balanced reaction is:

4 FeS + 7 O₂ → 2 Fe₂O₃ + 4 SO₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

The molar mass of the compounds is:

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

The following rule of three can be applied: if by reaction stoichiometry 351.4 grams of FeS form 256 grams of SO₂, 124 grams of FeS form how much mass of SO₂?

[tex]mass of SO_{2} =\frac{124 grams of FeSx256 grams ofSO_{2}}{351.4 grams of FeS}[/tex]

mass of SO₂= 90.33 grams

The mass of carbon dioxide that would be produced by the complete combustion of 2.05 moles of sucrose is 1,082.4 g.

The complete combustion of sucrose in excess oxygen is given as follows;

C₁₂H₂₂O₁₁(s) + O₂(g) → CO₂(g) + H₂O(l)

balanced chemical equation is below;

C₁₂H₂₂O₁₁(s) + 12O₂(g) → 12CO₂(g) + 11H₂O(l)

from the reaction above;

1 mole of sucrose ----------> 12 mole of carbon dioxide

2.05 mole of sucrose ------> ?

= 2.05 x 12

= 24.6 moles

1 mole of carbon dioxide = 44 g/mole

24.6 moles = ?

= 24.6 x 44

= 1,082.4 g

Thus, the mass of carbon dioxide that would be produced by the complete combustion of 2.05 moles of sucrose is 1,082.4 g.

You can use CPR, where you lay a person back, hold their head up, and push on their chest to the beat "staying alive", in which it keeps their heart beating. If they aren't breathing, you can do mouth to mouth breathing, and continue the process until help arrives or.. the person is no longer with us.

If you have a defibrillator, you can use it on a low amp, or whatever amp you think would be most suitable for the condition of the person.

The theoretical yield of I2 in the reaction would be 0.23 g

This refers to the stoichiometric yield of a reaction.

From the equation of the reaction:

Ca(IO3)2 + 10 KI + 12 HCl → 6 I2 + CaCl2 + 10 KCl + 6 H2O

The mole ratio of Ca(IO3)2 and I2 is 1: 6

Mole of 15.00 mL, 0.0100 M Ca(IO3)2 = 15/1000 x 0.0100

                                                              = 0.00015 mole

Equivalent mole of I2 = 0.00015 x 6

                                      = 0.009 mole

mass of 0.0009 I2 = 0.0009 x 253.809

                                = 0.23 g
