Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

1 kg = 1000 g

2.06 kg = 2060 g

1 L = 1000 cm³

2 L = 2000 cm³

mass = 2060 g

volume = 2000 cm³

We have

[tex]density = \frac{2060}{2000} = \frac{103}{100} \\ [/tex]

We have the final answer as

Answer:

The density of milk is 1.03 g/cm³.

Explanation:

Given data:

Volume of milk = 2.00 L

Mass of milk = 2.06 kg

Density of milk = ?

Solution:

We know that density is equal to the mass divided by volume.

we will convert the unit first because we require the density in g/cm³.

2.06 kg ×1000 g/ 1 kg = 2060 g

2.00 L × 1000 mL / 1L = 2000 mL

d = m/v

d = 2060 g/2000 mL

d = 1.03 g/mL

mL = cm³

d = 1.03 g/cm³

Thus, density of milk is 1.03 g/cm³.

What is Chemical Indicator ?

Chemical indicators are substances that change color in response to changes in a chemical environment, such as changes in pH, temperature, or the presence of certain ions. They are commonly used in a variety of applications, such as quality control in manufacturing, medical diagnostics, and laboratory research. There are many different types of chemical indicators, including pH indicators, which change color in response to changes in the acidity or alkalinity of a solution, and redox indicators, which change color in response to changes in the oxidation state of a substance.

Answer:

2.7

Explanation:

The volume of stock solution they use to make the required solution is 6.94mL.

To calculate the value of required volume we will use the below equation:

M₁V₁ = M₂V₂, where

M₁ = molarity of stock solution = 18M

V₁ = volume of stock solution = to find?

M₂ = molarity of H₂SO₄ solution = 2.50M

V₂ = volume of H₂SO₄ solution = 50mL

On putting all these values on the above equation and calculate for the value of V₁ as:

V₁ = (2.50)(50) / (18)

V₁ = 6.94mL

Hence correct option is (3) i.e. 6.94mL.

Copper is unable to displace magnessium in a reaction so the copper sulfate solution was left for four minutes before adding the magnesium.

The electrochemical series shows the order of reactivity of the metals. The metals that are higher in the series can displace the metals that are lower in the series in a chemical reaction.

We know that copper is unable to displace magnessium in a reaction hence the reaction can not occur in the reverse direction. Hence, the copper sulfate solution was left for four minutes before adding the magnesium.

Answer:

Transverse!

Explanation:

Transverse is a more direct moving wave

The wave which is generated by moving a spring toy up and down is transverse wave. An electromagnetic wave is a transverse wave. The correct option is C.

A transverse wave is a progressive wave. The direction of propagation of a transverse wave is always perpendicular to its direction of vibration. They are non-mechanical waves which do not need a medium for propagation and they consists of crests and troughs.

When a toy spring is moved up and down, the generating waves that propagate in the horizontal direction while disturbing the toy spring in the vertical direction. In physics transverse wave is considered as a moving wave where oscillations are perpendicular to the direction of the wave.

The transverse waves are found commonly in elastic solids, oscillations, etc. The waves generated by moving a spring toy up and down is transverse wave.

Thus the correct option is C.

Improving the habitats of herring thereby increasing their population.

Explanation:

First, two consumers (Steller sea lion and  Pollock) are both competing for common prey (herring). Since the question only asked what could be done to increase the decreasing Steller sea lion population of Alaska, the focus would be made only on the Steller sea lion.

The Steller sea lion population would increase if:

1. The herring population should be increased by improving the food available for them to feed on, and improving their reproduction capacities to enable them to reproduce efficiently.

2. Since there are 2 predators. If the population of the prey is fixed, then Pollock should be more hunted by farmers or other biological means to eliminate competition.

Answer:

3.06 g/L

Explanation:

Taking into account the definition of density and ideal gas law, the density of aluminum chloride vapor (AlCl₃) at 498 K and 0.939 atm is 3.06 g/L.

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.

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

From the Ideal gas law, you can get that:

[tex]\frac{n}{V} =\frac{P}{RxT}[/tex]

On the other side, the molar mass of substance is a property defined as the amount of mass that a substance contains in one mole. It can be expressed as:

[tex]molar mass= \frac{mass}{number of moles}[/tex]

Then, the number of moles n can be calculated as:

[tex]n=\frac{mass}{molar mass}[/tex]

So:

[tex]\frac{\frac{mass}{molar mass} }{V} =\frac{P}{RxT}[/tex]

Solving you get the expression:

[tex]\frac{mass }{V} =\frac{Pxmolar mass}{RxT}[/tex]

Considering the definition of density, you finally get:

[tex]density=\frac{Pxmolar mass}{RxT}[/tex]

In this case, you know:

Replacing in the previous expression for the calculation of the density:

[tex]density=\frac{0.939 atmx133.35\frac{g}{mol} }{0.082\frac{atm L}{molK} x498 K}[/tex]

and solving you get:

density= 3.06 g/L

Finally, the density of aluminum chloride vapor (AlCl₃) at 498 K and 0.939 atm is 3.06 g/L.

An item which is experiencing a phase change is water boiling in a tea kettle.

The conversion of matter from one  state to another is called as phase change.The process is accompanied by a large amount of energy being evolved or absorbed during the process. It also depends on factors like temperature and pressure.

Each form of matter has it's own characteristic properties like specific heat, melting and boiling points . There are eight thermal processes through which matter undergoes phase change. They are as  follows:1) freezing 2) melting  3)vaporization 4)condensation 5)sublimation 6)deposition 7)ionization 8) recombination.

These eight phases exist at different temperatures  and pressures.The heat transfer process takes place in three ways which are conduction, convection and radiation.
