Answers

Answer:

C. A Spring Scale

Explanation:

Using process of elimination, we can quickly decide that a stopwatch and a ruler will not be useful in measuring the force. This leaves us with either the spring scale or a balance scale. A balance scale is used to compare two weights, so this is eliminated. That leaves us with a spring scale. This is because we can attached the spring scale to the car and when we let it go, we can record the force. I hope this helps!

Continual eruptions occur along mid-ocean ridges, forming new sea-floor rock. The
rocks closest to a mid-ocean ridge are the youngest | oldest. As you move away from
a mid-ocean ridge, the rocks get younger | older. This implies that crust is being

Answers

The characteristics of the ocean ridges allow finding the results to complete the statements are:

The rocks near the ridge are YOUNGER. While you walk away the rocks are OLDER. This implies that the cortex is PRODUCING in the ridges.

The oceanic ridges are mountain ranges or chains of volcanic mountains at the bottom of the ocean, in these the magma that rises cools and forms young rocks, in they are pushed by the other rocks that emerge, in general they are located on the edges of the tectonic plates .

Therefore, the oceanic ridges are the point where the earth's crust is separating, therefore it has the youngest rocks and in the furthest points it has the oldest.

Let's find the correct words for each phrase to be correct:

The rocks near the ridge are YOUNGER. You walk away the rocks are OLDER. This implies that the cortex is PRODUCING in the ridges.

As a consequence of the characteristics of the ocean ridges, we can find the results to complete the statements  are:

Which equation represents a chemical reaction

Answers

Answer:

A balanced chemical equation represents a chemical reaction that obeys the Law of Conservation of Mass (Matter). It can be thought of as describing how many atoms or molecules of reactants are consumed in order to produce a certain number of atoms or molecules of products.

An environmental chemist analyzed the effluent (the released waste material) from an industrial process known to produce the compounds carbon tetrachloride (CC14) and benzoic acid (HC7H5O2), a weak acid that has one acidic hydrogen atom per molecule. A sample of this effluent weighing 0.3518 g was shaken with water, and the resulting aqueous solution required 10.59 mL of 0.1546 M NaOH for neutralization. Calculate the mass percent of HC7H5O2 in the original sample.

Answers

The mass percent of benzoic acid in the sample is 55.5%.

The equation of the reaction is; HC7H5O2(aq) + NaOH(aq) ----> NaC7H5O2(aq) + H2O(l)

Number of moles of NaOH reacted = concentration × volume

Number of moles of NaOH reacted = 10.59/1000 L × 0.1546 M

Number of moles of NaOH reacted = 0.0016 moles of NaOH

Since the reaction is 1:1, 0.0016 moles of HC7H5O2 reacted also.

Hence, mass of HC7H5O2 = 0.0016 moles × 122 g/mol = 0.1952 g

Mass percent of HC7H5O2 in the original sample = 0.1952 g/ 0.3518 g × 100 = 55.5%

Answers

The density of the rectangular block is 1.07 g/mL.

From the question, we have the mass of the rectangular block as 121g

The dimensions of the block are given as follows;9.1cm by 5.4cm by 2.3cm

So we have the volume of the block as; 9.1cm × 5.4cm ×  2.3cm = 113 cm^3

Let us recall that; 1 cm^3 = 1 mL, so 113 cm^3 = 113 mL

Having said that, we must also remember that;

Density = Mass/volume

Density = 121g/113 mL

Density = 1.07 g/mL

You have 150.0 mL of a 0.415 M solution of Ce(NO₃)₄.

a) What mass (in grams) of Ce(NO₃)₄ would be required to make the solution?
B) What is the concentration of the nitrate ions in the solution ?

C) If the original solution was diluted to 350.0 mL, what would be the new concentration of the Ce(NO₃)₄ in the solution?

Answers

A. The mass (in grams) of Ce(NO₃)₄ that will be required to make the solution is 24.16 g

B. The concentration of the nitrate ions in the solution is 1.66 M

C. The new concentration of the Ce(NO₃)₄ solution is 0.178 M

We'll begin by calculating the number of mole of Ce(NO₃)₄ in the solution.

Molarity = 0.415 M

Volume = 150 mL = 150 /1000 = 0.15 L

Mole of Ce(NO₃)₄ =?

Mole = Molarity × Volume

Mole of Ce(NO₃)₄ = 0.415 × 0.15

Mole of Ce(NO₃)₄ = 0.06225 mole

A. Determination of the mass of Ce(NO₃)₄ required to make the solution.

Mole of Ce(NO₃)₄ = 0.06225 mole

Molar of Ce(NO₃)₄ = 140.12 + 4[14 + (16×3)]

= 140.12 + 4[14 + 48]

= 140.12 + 4[62]

= 140.12 + 248

= 388.12 g/mol

Mass of Ce(NO₃)₄ =?

Mass = mole × molar mass

Mass of Ce(NO₃)₄ = 0.06225 × 388.12

Mass of Ce(NO₃)₄ = 24.16 g

Therefore, 24.16 g of Ce(NO₃)₄ is required to make the solution.

B. Determination of the concentration of the nitrate ion, NO₃¯ in the solution.

In solution, Ce(NO₃)₄ will dissociate as follow:

Ce(NO₃)₄ (aq) —> Ce⁴⁺(aq) + 4NO₃¯(aq)

From the balanced equation above,

1 mole of Ce(NO₃)₄ contains 4 moles of NO₃¯

Therefore,

0.415 M solution of Ce(NO₃)₄ will contain = 0.415 × 4 = 1.66 M NO₃¯

Thus, 1.66 M of the nitrate ion, NO₃¯, is present in the solution.

C. Determination of the new concentration of the Ce(NO₃)₄ solution.

Volume of stock solution (V₁) = 150 mL

Molarity of stock solution (M₁) = 0.415 M

Volume of diluted solution (V₂) = 350 mL

Molarity of diluted solution (M₂) =?

M₁V₁ = M₂V₂

0.415 × 150 = M₂ × 350

62.25 = M₂ × 350

Divide both side by 350

M₂ = 62.25 / 350

M₂ = 0.178 M

Therefore, the new concentration of the Ce(NO₃)₄ solution is 0.178 M

Using value of 1.1×10−10 for the Ksp, calculate how many milligrams of Ag2CrO4 will dissolve in 11.5 mL of H2O

Answers

Answer:

i think it might be 3.8 milligrams but to be honest i dont know im just trying to help

Explanation:

Using value of 1.1×10−10 for the Ksp, 1.0 milligrams of Ag₂CrO₄ will dissolve in 11.5 mL of H₂O.

What is mass?

Mass is defined as the quantity of material that makes up a thing, whereas weight is the force that an object produces. A particle's or an object's mass is a dimensionless number that indicates how much matter is present. Gravity and inertia, which are the two main forces influencing how objects move in space, make mass crucial.

Ag2CrO4 dissociates to form Ag2CrO4 (s). aq 2Ag+ + crO4 (aq)

Ksp = [2Ag+] is an expression for the solubility product constant.

[Ag+] = 2x & [CrO4-] = x 1.1 10 10 = 2[CrO4-] (2x)

2(x) = 4x3 / x = [(1.1×10−10)/4]

1/3 = 3.02 x 10-4 M

Determine the number of CrO4- moles dissolved in 10 ml of water.

Molarity of CrO4- is equal to the number of moles of CrO4- divided by the volume in liters (3.02 x 10-4 M) (10 x 10-3 L)

Number of CrO4- moles equals (3.02 x 10-4)(10 x 10-3) = 3.02 x 10-6 mole.

Number of CrO4- = Number of Ag2CrO4 moles

                             = 3.02 x 10-6 mole

Ag2CrO4's molar mass = 331.73 g/mole.

3.02 x 10-6 mole of dissolved Ag2CrO4 in water

= 0.0010 g,

= 1.0 milligram.

Thus, using value of 1.1×10−10 for the Ksp, 1.0 milligrams of Ag₂CrO₄ will dissolve in 11.5 mL of H₂O.

Explanation:

because your separating the atoms in the water

The appropriate model for nuclear fission is disturbing a drop of water such that it breaks into smaller droplets.

Nuclear fission refers to the disintegration of a large nucleus when it is bombarded with a small particle.

Usually, the protons in the nucleus repel each other strongly. Hence, as the atomic number of atoms continues to increase, this repulsion exceeds the nuclear attractive force causing the atom to disintegrate into smaller fragments called daughter nuclei when disturbed just as a drop of water such that it breaks into smaller droplets  when disturbed.

The volume would be lower than predicted by the Ideal Gas Law

The volume would be higher than predicted by the Ideal Gas Law

The volume would be exactly the same as predicted by the Ideal Gas Law

Answers

Under conditions of very high pressures, the volume would be lower than predicted by the Ideal Gas Law.

According to the kinetic theory of gases, a gas spreads out to fill the volume of the container holding it. Hence a gas does not have a definite volume due to the fact that there is no inter-molecular interaction between gas molecules.

When the gas is subjected to very high pressure, inter-molecular interactions become significant leading to a decrease in the volume of the gas.

Therefore, when subjected to high pressure, the experimental volume would be lower than predicted by the Ideal Gas Law.
