Which of the following describes the energy transformations that occur when a toaster is used to make toast?

Thermal energy is transformed into chemical energy in the toaster, and chemical energy is transformed into thermal energy in the toast.

Electrical energy is transformed into thermal energy in the toaster, and chemical energy is transformed into thermal energy in the toast.

Light energy is transformed into thermal energy in the toaster, and thermal energy is transformed into chemical energy in the toast.

Electrical energy is transformed into thermal energy in the toaster, and thermal energy is transformed into chemical energy in the toast.

Answers

Answer:

Thermal energy (B)

Explanation:

just did it

Electrical energy is transformed into thermal energy in the toaster, and chemical energy is transformed into thermal energy in the toast. Hence option b is correct.

What is chemical energy?

Chemical energy is defined as chemical substances' potential energy, which is released as they experience chemical reactions and change into other substances. Additionally, it is what binds a substance's molecule's together. The body transforms or changes the chemical energy in food into heat and mechanical motion.

The wire attached to the power source transmits electrical energy to the toaster. The heating element is a part of the toaster. This heating element transforms electrical energy into heat energy, which aids in toast preparation, when it comes into contact with it. Thus, with an electric toaster, electrical energy is converted to heat energy.

Thus, electrical energy is transformed into thermal energy in the toaster, and chemical energy is transformed into thermal energy in the toast. Hence option b is correct.

Calcium carbonate (limestone) decomposes when heated.
Caco, + CaO + CO2

b) Calculate the volume of carbon dioxide produced if 10 grames were decomposed.​

Answers

Explanation:

Equation -

CaCO₃ → CaO + CO₂

molecular masses of -

CaCO₃ = 40+12+16×3 = 100 g/mol

CaO = 40+16 = 56 g/mol

CO₂ = 12+16×2 = 44 g/mol

Now,

If 100 g of CaCO₃ is decomposed then it produces 56 g of CaO and 44g of CO₂

Then,

If 1 g of CaCO₃ is decomposed then it produces 56/100g of CaO and 44/100g of CO₂

Now,

Here in question, 10g of CaCO₃ is decomposed

It means, It produces

56/100 × 10 = 56/10 = 5.6 g of CaO and

44/100 × 10 = 44/10 = 4.4 g of CO₂

Now,

we get that 10 g of CaCO₃ on burning produces 4.4 g of CO₂

we need to calculate volume of 4.4 g of CO₂

mole = mass/Gram molecular mass

Then,

mole = 4.4/44 = 0.1

Now,

volume = mole × 22.4 (in Litres)

= 0.1 × 22.4 = 2.24 L

Hence,

2.24 L of CO₂ will be produced when 10g of CaCO₃ decomposed.

What is the name and formula of an ionic compound containing the element with the
atomic number of 5 bonded to Carbonate? *
Boron Carbonide; B2(CO3)3
Boron Carbonate; B,CO,
Boron Carbide; B,CO,
Boron Carbonate; B2(CO3)3

Answers

Answer:

Boron Carbonate; B₂(CO₃)₃

Explanation:

For names, carbonide does not exist; that rules out the first option. Carbide refers to just a carbon atom, not carbon and oxygen as in the polyatomic ion carbonate. That rids us of the third option. We are left with boron carbonate with the formula BCO or boron carbonate with the formula B₂(CO₃)₃.

Recall the carbonate polyatomic ion's formula: CO₃²⁻

Thus BCO cannot be the formula.

Option 4 is your answer, Boron Carbonate; B₂(CO₃)₃.

To further check your answer, observe the oxidation states of boron and the polyatomic ion carbonate. Boron can exist in oxidation states of either 2+ or 3+, and carbonate is only 2-; in this formula, boron will exhibit a 3+ state to balance out with carbonate.

2x3+ = 6+; 3x2- = 6-

6+ + 6- = 0; balanced

An object has a mass of 441 g and a volume
of 10 cm3. What is the density of the object
in g/cm3?

Answers

The density is the ratio of the mass to the volume. The density of the object is 44.1 g/cm³.

What is density?

Density (ρ) is the quantitative measurement of the substance having grams of mass that are dissolved per cubic meter of the solution. The density is calculated as:

ρ = M ÷ V

Given,

Mass of the object = 441 gm

The volume of the object = 10 cubic meter

Density is calculated as:

ρ = 441 ÷ 10

= 44.1 g/cm³

Therefore, 44.1 g/cm³ is the density of the object.

If the temperature of a substance increases will the particles of that substance be moving faster or slower or at the same speed as they were before the temperature changed

Answers

Answer:

If the temperature increases, temperature reflects the speed of the molecules, so if the molecules are at a higher temperature, they are faster and they start to break bonds and new things react.

Which air is driest? Air Temp 30F Dew-point 29F, Air Temp 77F Dew-point 19F, Air Temp 66F Dew-point 60F, or Air Temp 50F Dew-point 36F

Answers

Answer:

Air Temp 77F Dew-point 19F

Explanation:

Quiz

The dew point can be described as the temperature required by the air to be cooled. The driest air will have a higher dew point, therefore, at an air temperature of 66°F and a dew point of 60°F. Therefore, option (C) is correct.

What is dew point?

The dew point can be defined as the temperature at which air should be cooled to become saturated with water vapor assuming constant air pressure and water content.

Moisture capacity will decrease below the dew point. Airborne water vapor will condense to form liquid water or dew. Dew develops on the surface and occurs through contact with a cooler surface.

The dew point is called the frost point when the temperature is below the freezing point because frost is produced by deposition rather than a condensation of water.

The humidity also impacts the dew point. The dew point increases when there is higher moisture in the atmosphere.  Therefore, the higher dew point refers to less humid air or drier.

The following passage was adapted from text by the Oklahoma Historical Society. Which part of the passage best explains why the United States did not want to allow Indian Territory to become its own state? The goal of the Sequoyah Convention was to draft a constitution for a proposed single state made from Indian Territory. Delegates were chosen in mass meetings held across Indian Territory. Until 1903, the Five Civilized Tribes and other tribes in Indian Territory had generally opposed all local and national efforts for statehood. In 1905, the end of tribal governments loomed, as prescribed by the Curtis Act, and the tribes knew they faced the prospect of joint statehood with Oklahoma Territory. Their desire for Indian Territory to be admitted as its own state resulted in the Sequoyah Convention, which met August 21 and 22 and September 5 through September 8, 1905. The convention drafted a constitution that was about 35,000 words in length, which was perhaps the convention's greatest contribution to Oklahoma history. But territorial leaders realized that the Republican-led US Congress was unlikely to admit a heavily Democratic Indian Territory. Still, single-state supporters and Indian Territory leaders pressed onward. However, the US Congress refused to consider statehood for the state of Sequoyah. Joint statehood, the joining of Indian Territory and Oklahoma Territory to form Oklahoma, occurred on November 16, 1907. Reset Next PLEASE HELP!
