The model represents how electromagnetic radiation transmits energy.
What does the model show?
A. Many light waves traveling away from a source
O B. Two light waves traveling perpendicularly to a source
C. Several light waves circling a source
D. A single light wave traveling away from a source.
Answers
The model represents where electromagnetic radiation transmits energy should be option d. A single light wave traveling away from a source.
What is electromagnetic radiation?It is the energy that should be transmitted at the fixed velocity via the sinusoidally that varied from the electric and magnetic fields.
Here the frequency of variation of the energy should be presented by the Greek letter ν.
Hence, the option d is correct.

The model depicts the transmission of energy by electromagnetic radiation. The model depicts a single light wave departing from a source.
What describes the light as electromagnetic waves?Light as a wave: Light is a type of electromagnetic wave that can be represented mathematically (described). A shifting magnetic field is produced by a shifting electric field, according to this paradigm. Light is produced when the electric field changes as a result of the changing magnetic field.Light can be thought of as a wave. Light is a type of electromagnetic wave. A fluctuating electric field, according to this hypothesis, generates a fluctuating magnetic field. The interaction of a changing magnetic field with a changing electric field produces light. When charged particles, such as electrons and protons, move, they generate electromagnetic fields, which transport the type of energy known as electromagnetic radiation, or light.To Learn more About electromagnetic radiation, Refer:

Use the balanced equation given below to solve the following problem; Calculate the volume in liters of CO produced by the reaction of 175 g of Sb2O3.
Sb2O3 + 3 C --> 2 Sb + 3 CO
40.3 L CO
7.81 L CO
20.2 L CO
13.4 L CO
Answers
Answer: 40.3 L
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} Sb_2O_3=\frac{175g}{291.5g/mol}=0.600moles[/tex]
[tex]Sb_2O_3+3C\rightarrow 2Sb+3CO[/tex]
According to stoichiometry :
1 moles of [tex]Sb_2O_3[/tex] produces = 3 moles of [tex]CO[/tex]
Thus 0.600 moles of [tex]Sb_2O_3[/tex] will produce=[tex]\frac{3}{1}\times 0.600=1.80moles[/tex] of [tex]CO[/tex]
Volume of [tex]CO=moles\times {\text {Molar volume}}=1.80moles\times 22.4L/mol=40.3L[/tex]
Thus 40.3 L of CO is produced.

steam at130˚C.
Answers
Answer:
How much heat energy required to convert following?
How much heat energy, in kilojoules, is required to convert 47.0 g of ice at -18.0 C to water at 25.0 C ?
Specific Heat of Ice - 2.09 j/g * c
This is how I did it and the answer is wrong...Please check and correct me
Q = m * Cice * Change in Temp
Q = (47.0 g)(2.09 J/g*c)(43) = 4222.6 J * 0.001 kj / j = 4.22 kj

A rectangular box has the following dimensions on the inside: 5 cm x 5 cm x 10 cm. What volume can the box hold, in milliliters?
- 20 mL
- 259 mL
- 25 mL
- 50 mL
Answers
Answer:
The volume in milliliters is 250mL
Explanation:
The volume of a rectangle is obtained using the equation:
Volume = Length * Width * Height
In the problem, we can take length as 5cm, width as 5cm and height as 10cm. Thus, volume of the rectangular box is:
Volume = 5cm * 5cm * 10cm
Volume = 250cm³
1mL = 1cm³.
That means the volume in milliliters is 250mL

Sodium is a soft, white metal that reacts violently with water. Chlorine is a poisonous yellow-green gas. During the chemical reaction between sodium and chlorine, table salt is produced. Which of the following statements correctly compares and contrasts the reactants with the resulting products used in a chemical equation?
A. The reactants are dangerous and the product can be eaten
B. The reactants and the products observe the law of conservation of mass
C. The reactants are a solid and a gas and the product is a gas
D. The reactants and the products are the same color
Answers
Answer:
B. The reactants and the products observe the law of conservation of mass
Explanation:
The reaction equation is given as:
2Na + Cl₂ → 2NaCl
Such a chemical reactions usually obeys the law of conservation of mass. The law states that "in a chemical reaction, matter is neither created nor destroyed but bonds are rearranged".
So, the most correct thing is that reactants and products observe the law of conservation of mass. The number of atoms on both sides of the expression will be the same. Therefore, option B is correct.Which statement about the alkali metals is correct?
