Which of the following factors affects the amount of heat absorbed by a substance?
A. Boiling point of the substance
B. Specific heat capacity of the substance
C. Melting point of the substance
D. Shape of the substance

Answers

Answer:

The correct answer is B, "Specific heat capacity of the substance."

Explanation:

I just took the test. I hope this helps!

Heat absorbed changes the bonds of the molecules or the compounds to alter their state. The specific heat capacity affects the amount of heat absorbed. Thus, option B is correct.

What is specific heat capacity?

Specific heat capacity is defined as the amount of heat or energy absorbed by the kilogram of the solid reactant when the system experiences a rise in temperature. It is measured in J/(kg K) or J/(kg °C).

The specific heat capacity, the mass of the substance, temperature, and the phase of the substance affects the absorption of the heat from the surrounding. The specific heat affects absorption as it tells about the substance's ability to take the heat energy.

Therefore, specific heat capacity affects heat absorption.

TEACH ME how to do question 2 through your explanations.

Answers

Answer:

Explanation:

The first two are easy:

H2O, H3O+ and OH- all exist in an equilibrium

[H3O+] = [OH-] = 10^-7 M

HCl is a strong acid so 1M of it will disassociate completely

[H3O+] = [Cl-] = 1 M

The third one is also an equilibrium as HNO2 is a weak acid. Ka is given so [HNO2] and [NO2-] can be calculated.

The fourth one is a buffer solution so its pH can be looked up to give the concentrations.

Answer:

Explanation:

H20 has pH of 7

1st reaction [H30+] = 10^-7M

[OH-] = 10^-7M

1M HCl has pH of 0

2nd reaction [H3O+] = 1M

[Cl-] = 1M

given Ka = 4.6x10^-3 = [H3O+]x[NO2-] / [HNO2]

and [HNO2] + [NO2-] = 1M

each concentration can be solved

beaker D is a buffer solution n requires more info 2 solve

What are the consequences of purposely having an excess of one of the reactants?

Answers

Answer:

When one reactant is in excess, there will always be some left over. The other reactant becomes a limiting factor and controls how much of each product is produced. While using excess reactants can help to increase percentage yields, this is at the expense of atom economy.

Explanation:

Is everything correct?

Answers

Yes everything is correct! You’re doing an amazing job!
Yes everything is correct your doing a great job

Magnesium (used in the manufacture of light alloys) reacts with iron(III) chloride to form magnesium chloride and iron. A mixture of 41.0 g of magnesium and 175.0 g of iron(III) chloride is allowed to react. Identify the limiting reactant and determine the mass of the excess reactant present in the vessel when the reaction is complete. Select one: a. Limiting reactant is Mg; 7.4 g of FeCl3 remain. b. Limiting reactant is Mg; 46.5 g of FeCl3 remain. c. Limiting reactant is FeCl3; 1.7 g of Mg remain. d. Limiting reactant is FeCl3; 37.8 g of Mg remain. e. Limiting reactant is Mg; 134.0 g of FeCl3 remain.

Answers

Answer:

Limiting reactant is FeCl3; 1.7 g of Mg remain.

Explanation:

From the question;

The equation is;

3Mg(s) + 2FeCl₃(s) → 3MgCl₂(s) + 2Fe(s)

Amount of Mg = 41 g/24.31 g/mol = 1.687 moles

The limiting reactant yields the least amount of MgCl2

3 moles of Mg yields 3 moles of MgCl2

Hence 1.687 moles of Mg yields yields 1.687 moles of MgCl2

FeCl₃ = 175 g/162.2 g/mol = 1.0789 moles

2 moles of FeCl3 yields 3 moles of MgCl2

1.0789  moles of FeCl3 yields 1.0789  * 3/2 = 1.61835 moles of MgCl2

Hence FeCl3 is the limiting reactant

3 moles of Mg reacts with 2 moles of FeCl3

x moles of Mg reacts with 1.0789  of FeCl3

x = 3 * 1.0789  /2 = 1.61835 moles of Mg

Mass of Mg reacted = 1.61835 moles * 24.31 = 39.342 g

Mass of excess Mg = 41 g - 39.342 g = 1.7 g

Considering the ideal gas law, when pressure, volume, and temperature of a gas are known the ideal gas law can be used to calculate the number of moles (option c).

Ideal gas law

An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of gases:

P×V = n×R×T

This case

Being R the molar constant of gases, when pressure, volume, and temperature of a gas are known the ideal gas law can be used to calculate the number of moles (option c).

PLEASE ANSWER ASAP GIVE BRAINLIEST

Answers

Human activities that increase the amount of CO2 in the atmosphere include, the burning of coal/ other fossil fuels, cement production, deforestation, and other landscape changes.

Climate change causes the oceans to absorb more heat, resulting in an increase in sea surface temperatures and rising sea levels. This change in ocean temperatures and currents brought about by climate change can lead to alterations in climate around the world.

Climate changes affects crop growth, meat production, fisheries, and other fundamental aspects of our food supply. This is because if our climate is constantly changing our Earth will no longer be able to sustain the adequate necessities of food production.

Climate change cause health issues. Change in climate can cause existing health problems to intensify and new health issues to emerge. Climate change can influence air pollution, allergies, disease carried by vectors, food and waterborne diseases, food security, mental health and stress-related disorders, floods, temperature extremes, and wildfires. All of these factors can have negative effects on ones health.

To reduce the negative effects of climate change we can speak up about climate change, use renewable energy, weatherize, invest in energy-efficient appliances, reduce water waste, make less food waste, etc.

What is the voltage of a galvanic cell made with zinc (Zn) and aluminum (AI)? A. 0.92 V
B. -0.92 V
c. -2.44 V
D. 2.44 V​

Answers

Answer:

The correct option is (a) "0.92 V".

Explanation:

The voltage of a galvanic cell made with zinc (Zn) and aluminum (AI) is given by :

Voltage =Ered- Eoxd

Where

Ered = reduction potential

Eoxd = oxidation potential

As per reduction standard potentials, the emf of Zinc is -0.76 V  and the emf of Aluminium is -1.66 V. So,

V = 0.76 - (-1.66)

= 0.9 V

Hence, the correct option is (a) "0.92 V".

Answers

Answer:

0.0038 mole s-1

Explanation:

La velocidad de una reacción se refiere a la rapidez o la lentitud con que avanza una reacción. Se mide por la cantidad de reactivos que desaparecen por unidad de tiempo o por la cantidad de productos que aparecen por unidad de tiempo.

Número de moles de zinc = 5g / 65.37gmol-1 = 0.076 moles

Velocidad de reacción = 0.076 moles - 0 moles / 20 s - 0s = 0.0038 mole s-1
