The image shows a ship using sonar to locate a school of fish. Which data are used to determine the distance of the ship from the fish? O A. The amount of time it takes the sound waves to travel from the boat to the fish B. The number of sound waves that bounce off the fish C. The number of sound waves the ship emits D. The amount of time it takes the sound waves to travel to the fish and back to the boat
Answers
The factor that would help to determine the distance of the ship from the fish would be The amount of time it takes the sound waves to travel to the fish and back to the boat.
What is distance traveled by a wave?This is the term that is used to refer to the total distance that would be traveled by a wave in a given cycle. The distance is usually calculated by the use of lambda. The use of Sonar would have to be determinant on the sound that is being heard.
We would have to check the way that the sound would have to come from the ship and then the way that it would have to be go back to the given boat that is used to report and find the school of fisn.
Hence we would say that The factor that would help to determine the distance of the ship from the fish would be The amount of time it takes the sound waves to travel to the fish and back to the boat.

Find the normality of 0.321 g sodium carbonate in a 250 mL solution.
Answers
Answer:
the normality of the given solution is 0.0755 N
Explanation:
The computation of the normality of the given solution is shown below:
Here we have to realize the two sodiums ions per carbonate ion i.e.
N = 0.321g Na_2CO_3 × (1mol ÷ 105.99g)×(2eq ÷ 1mol)
= 0.1886eq ÷ 0.2500L
= 0.0755 N
Hence, the normality of the given solution is 0.0755 N

Nitric acid decomposes in light to form nitrogen dioxide, water, and oxygen, according to the following chemical equation.
4HNO3 (l â 4NO2(g) + 2H2O (l) + O2(g)
If 2.5 g nitric acid decomposes, what is the total volume of gas produced?
a. 0.050L
b. 0.22
c.0.89
d. 1.1L
Answers
Answer:
b. 0.22 L
Explanation:
Step 1: Write the balanced equation
4 HNO₃(l) ⇒ 4 NO₂(g) + 2 H₂O(l) + O₂(g)
Step 2: Calculate the moles corresponding to 2.5 g of HNO₃
The molar mass of HNO₃ is 63.01 g/mol.
2.5 g × 1 mol/63.01 g = 0.040 mol
Step 3: Calculate the moles of O₂ produced from 0.040 moles of HNO₃
The molar ratio of HNO₃ to O₂ is 4:1. The moles of O₂ produced are 1/4 × 0.040 mol = 0.010 mol.
Step 4: Calculate the volume corresponding to 0.010 moles of O₂
Assuming the reaction takes place at standard temperature and pressure, the volume of 1 mole of O₂ is 22.4 L.
0.010 mol × 22.4L/1 mol = 0.22 L

Choose all true statements about the water molecule: Choose all true statements about the water molecule: Bonding between the oxygen and hydrogen within the molecule happens due to hydrogen bonding. Water is a permanent electric dipole, having permanent charge separation. Water is not naturally polarized, and gets polarized only due to external electric forces.
Answers
Answer: Water is a permanent electric dipole, having permanent charge separation.
Explanation:
Hydrogen bonding is an intermolecular force having partial ionic-covalent character.
In [tex]H_2O[/tex], O is a highly electronegative atom attached to a H atom through a covalent bond. The oxygen atoms being more electronegative gets partial negative charge and H atom gets partial positive charge. Thus water is permanent electric dipole.
Hydrogen bonding takes place between a hydrogen atom (attached with an electronegative atom O) and an electronegative atom (O).
The true statement about water molecules are Bonding between the oxygen and hydrogen within the molecule happens due to hydrogen bonding and water is a permanent electric dipole, having permanent charge separation.
What are hydrogen bonds?Hydrogen bonds is a kind of attraction force which is present between the more electronegative atom and hydrogen atom.
In water molecule, 2 hydrogen atoms and one oxygen atom is present and between the more electronegative oxygen atom and hydrogen atom, hydrogen bond is present.And due to electronegative nature of oxygen atom, they withdraw all the electron density of the bond towards itself as a result of which it possesses permanent electric dipole. Because partial negative charge is present on oxygen atom and partial positive charge is present on the hydrogen atom.Hence options (1) and (2) are correct.

c) As the pressure increases, helium atoms stay closer to the wall of the container, on average.
d) As the pressure increases, the volume of the container must decrease.
e) As the pressure increases, there are more collisions of helium atoms with the container wall.
Answers
Answer: e. As the pressure increases, there are more collisions of helium atoms with the container wall.
Explanation:
We are given the information that helium gas is pumped into a rigid container at a constant temperature.
Due to this reason, there was a rise in the pressure of helium in the container. We should note that as the pressure rises, there are more collisions of helium atoms with the container wall.
The increase in the pressure of He atoms results in the increased collision of atoms with the wall. Thus, option E is correct.
The helium in the container is assumed to be an ideal gas. The ideal gas reaction is given as:
[tex]PV=nRT[/tex]
Where,
P= PressureV=volumen=molesR=Rydberg constantT=temperatureWhat happens to gas with an increase in pressure?The ideal gas equation depicts that the gas is contained in a closed container. Thus, the moles, n of gas are constant. The pressure is pumped at a constant temperature, thereby T is also constant.
The R is a constant in the ideal gas equation. The increase in the pressure of the container results in the increased kinetic energy of the helium atoms.
The increase in the collisions is observed for the molecules with the container wall.
Thus, with the increase in pressure, the collisions in the atoms increase. Hence, option E is correct.

Determine the theoretical yield of P4 if 293.5 g Ca3(PO4)2 and 378.5 g SiO2 are heated. (No Response) g If the actual yield of P4 is 44.9 g, determine the percent yield of P4.
Answers
Answer:
76.6% is percent yield of P₄
Explanation:
Percent yield is defined as 100 times the ratio of actual yield and theoretical yield. To solve this quesiton we need to find the theoretical yield of the reaction. Using:
2Ca₃(PO₄)₂(s) + 6SiO₂(s) → 6CaSiO₃(l) + P₄O₁₀(g)
P₄O₁₀(g) + 10C(s) → P₄(g) + 10CO(g)
We need to find the moles of Ca₃(PO₄)₂ and SiO₂ to find limiting reactant. With limiting reactant we can find moles of P₄O₁₀ = Moles of P₄. We must convert the moles of P₄ to mass using Molar mass (P₄ = 123.895g/mol):
Moles Ca₃(PO₄)₂ -Molar mass: 310.1767g/mol-
293.5g * (1mol / 310.1767g) = 0.9462moles
Moles SiO₂ -Molar mass: 60.08g/mol-:
378.5g * (1mol / 60.08g) = 6.30 moles
For a complete reaction of 6.30 moles of SiO₂ there are required:
6.30 moles SiO₂ * (2 moles Ca₃(PO₄)₂ / 6 moles SiO₂) =
2.10 moles Ca₃(PO₄)₂. As there are just 0.9462 moles, Ca₃(PO₄)₂ is limiting reactant
Moles P₄O₁₀ = Moles P₄:
0.9462moles Ca₃(PO₄)₂ * (1mol P₄O₁₀ / 2 mol Ca₃(PO₄)₂) = 0.4731 moles P₄O₁₀ = Moles P₄.
The mass is:
0.4731 moles P₄ * (123.895g / 1mol) = 58.6g = Theoretical yield.
Percent yield is:
44.9g / 58.6g * 100 =
76.6% is percent yield of P₄When you need to produce a variety of diluted solutions of a solute, you can dilute a series of stock solutions. A stock solution has a significantly higher concentration of the given solute (typically 101 to 104 times higher than those of the diluted solutions).

What volume of a 6.57 M stock solution do you need to prepare 500. mL of a 0.0490 M solution of HCl
Answers
Answer:

Explanation:
To solve this problem we can use the equation C₁V₁=C₂V₂, where:
C₁ = 6.57 MV₁ = ?C₂ = 0.0490 MV₂ = 500 mLWe input the data:
6.57 M * V₁ = 0.0490 M * 500 mLAnd solve for V₁:
V₁ = 3.73 mLSo 3.73 mL of a 6.57 M stock solution would be required to prepare 500 mL of a 0.0490 M solution.

A 2.060 g sample of copper (II) chloride hydrate was dissolved in 50.0 mL of deionized water. The concentration of copper (II) ion in the solution was determined spectrophotometrically using the equation from the calibration curve, was 0.200 M. Determine the formula of the copper (II) chloride hydrate.
Answers
Answer:
CuCl₂·4H₂O
Explanation:
First we calculate the moles of copper (II) ion in the solution, using the given volume and concentration:
50.0 mL ⇒ 50.0/1000 = 0.05 L0.05 L * 0.200 M = 0.01 mol Cu⁺²For each Cu⁺² mol there's also one CuCl₂ mol.
We convert 0.01 CuCl₂ moles into grams, using its molar mass:
0.01 CuCl₂ mol * 134.45 g/mol = 1.344 gThat means that out of the 2.060 g of the sample, 1.344 g are of CuCl₂. This means that there are (2.060 - 1.344) 0.716 g of water.
We convert those 0.716 g of water to moles:
0.716 g ÷ 18 g/mol = 0.04 mol H₂OThere are four times as many H₂O moles as there are CuCl₂ moles. This means the formula is CuCl₂·4H₂O
