Answer:

Direct

Explanation:

When the temperature increases with an increase in pressure, it is a direct relationship.

Gay-Lussac's law can be described as when the volume of the gas remains constant then the pressure of a gas is directly proportional to the absolute temperature of the gas.

The mathematical equation of Gay Lussca's law is written as follows:

P/T = k

It can be represented as the pressure is directly proportional to the absolute temperature.

P ∝ T               (where 'V' volume of gas is constant)

or

[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2}[/tex]

Where P₁ and T₁ are the initial temperature and pressure while P₂ and T₂ are the final pressure and temperature of the gas.

The sample of gas has a fixed volume of gas and on increasing the temperature the gas molecules acquire more and more kinetic energy. So the pressure of the gas will also increase.

Therefore, there will be a direct relationship between temperature and pressure of gas.

The balanced equation :

2KOH+CO₂⇒K₂CO₃+H₂O

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product

3. Select the coefficient of the substance with the most complex chemical formula equal to 1

Reaction

KOH+CO₂⇒K₂CO₃+H₂O

aKOH+bCO₂⇒K₂CO₃+cH₂O

K, left=a, right=2⇒a=2

H, left=a, right=2c⇒a=2c⇒2=2c⇒c=1

O, left=a+2b, right=3+c⇒a+2b=3+c⇒2+2b=3+1⇒2b=2⇒b=1

the equation becomes :

2KOH+CO₂⇒K₂CO₃+H₂O

If the chef is in a hurry we would assume he would want the pan to heat up so copper

Explanation:

Answer:

A. The chef should choose the copper pan.

Explanation:

Copper conducts heat well because its atoms contain only one free valence electrons in the outer shell. Elements with a low number of valence electrons transfer heat the best, and copper has only one. Valence electrons move about freely.

Good luck on your test (Or whatever it is) !!

Answer:

preservation of raw materials

Explanation:

Reusing and recycling is the process by which the used products are used again or recycled in different form to use it again. Excessive use of the raw materials can lead to their extinction. Recycling the materials helps in decreasing the pollution in the environment. It also helps in reduction in the emission of the harmful gases. When municipal wastes are reused or recycled, the raw materials are preserved. These are the process involved in sustainable use of resources.

Answer:

six

Explanation:

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.

Answer:

The water supply is not safe.

Explanation:

Ionically, the reaction is;

Pb^2+(aq) + 2Br^-(aq) -------> PbBr2(s)

Amount of Br^- reacted = 2/1000 * 0.12 = 2.4 * 10^-4 moles

From the reaction equation;

1 mole of Pb^2+ requires 2 moles of Br^- for complete precipitation

x moles of Pb^2+ requires 2.4 * 10^-4 moles of Br^-

x = 1 * 2.4 * 10^-4 /2

x = 1.2 * 10^-4 moles of Pb^2+

Concentration of Pb^2+ precipitated from 5ml of tap water =  1.2 * 10^-4 * 1000/5

Concentration = 2.4 * 10^-2 M

The amount of  Pb^2+ found in the water is greater than the maximum allowable concentration of Pb2+ ions in water in a local community which is 1.51 x 10-8 M. Therefore, the water supply is not safe.

Interference trust me I just did this

A light wave bends to pass through a crack underneath a door, this represents interference. The correct option is option C.

Like other waves, light waves also transfer energy to a source. They are made up of tiny energy particles known as photons. While photons have no mass, they do have momentum and energy.

There are types of light waves which human eyes cannot perceive, just as there are noises that can't be recognized because they fall outside the range of human hearing. However, all forms of waves share characteristics like wavelength and frequency. Wavelength is the separation between neighboring wave components (e.g., crest to crest or trough to trough). A light wave bends to pass through a crack underneath a door, this represents interference.

Therefore, the correct option is option C.

Answer:

0.272 mol AgOH

Explanation:

Figure out the amount of AgOH in mass, and to find the amount of moles–you just divide the given amount (34g) by the molar mass of AgOH (125g) to figure out the amount of moles. 34/125 = 0.272 mol AgOH.

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{8.50 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 14.119601...[/tex]

We have the final answer as
