Explanation:

The highest entropy will be 0 mL of water at 100°C.

Entropy is just a measured physical quality that will be most usually linked with disorder, unpredictability, or uncertainty.

The quantity of random movement in a system increases as more energy is put into it. Entropy rises like a volume increases in a system.

Therefore, the correct answer will be option 1.

How to calculate data involving metric units?

To convert from one unit to another within the metric system usually means moving a decimal point (e.g., 1000000mm = 100000cm = 10000dm = 1000m = 100dkm = 10hm = 1km).

Answer: Exploratorium Senior Scientist Paul Doherty explains why not—the orbit of the moon is tilted relative to the orbit of the Earth around the sun, so the moon often passes below or above Earth. At those times, it does not cross the line between the sun and the Earth, and therefore does not create a solar eclipse.

Answer:

producer to decomposer

Explanation:

This is because in a food chain , energy flow from one trophic level to another. The producer which include plants are the source of energy which they manufacture good in the presence of light energy from sun. Energy flow directly from the producer to the primary consumer which are heterotrophs that feed on plants. Energy flow from consumer to decomposer after the consumer died and it is decayed.

Answer:

Option 2 and 4 are correct

Explanation:

The reactants in the attached image have more enthalpy and hence less stability as they are more reactive. Thus, Product is more stable than the reactants.

This is an addition reaction in which two reactants add up to form the product.

Very less activation energy is required as the reactants themselves are unstable, possess high energy and hence are very reactive.

Reactants have more energy than the products.  

Answer:

moles = no. of molecules / Avogadro's number

         = 2.26 x 10^33 / 6.022 x 10^23

         = 3752906011

Round to significant figures which is 3 = 3.75 x 10^9 mol

Explanation: The formula for finding how many moles of a substance when given the amount of molecules is: moles = number of molecules / Avogadro's number

Answer:

Where is the chemical equations?

A balanced equation obeys the law of conservation of mass. The coefficient represent the number of molecules in a chemical equation.

An equation in which the number of reactants and products on the both sides of the reaction are equal can be defined as the balanced chemical equation. The coefficient are the numbers in front of the formula.

The coefficients are the numbers that must be added in front of the species involved in the reaction in order to balance it. It tells how many number of atoms or molecules are present in a reaction.

In the reaction N₂ + 3H₂ → 2NH₃ which is called Haber's process.

The coefficients are:

1 for Nitrogen molecule, 3 for Hydrogen molecule and 2 for the compound Ammonia.

Thus coefficients are numbers in front of each formula.

Answer:

New volume = 19.61 L

Explanation:

Given that,

Initial volume, V₁ = 18.2 L

Initial temperature, T₁ = 22°C = 295 K

Final temperature, T₂ = 45°C = 318 K

We neeed to find the new volume of the tire. The relation between volume and temperature is given by :

[tex]V\propto T\\\\\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}\\\\V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{18.2\times 318}{295}\\\\V_2=19.61\ L[/tex]

So, the new volume of the tire is equal to 19.61 L.

Answer:

0.205M

Explanation:

Molarity is an unit of concentration used in chemistry defined as the ratio between moles of solute (In this case, LiF) and liters of solution.

To solve this question, we must find the moles of LiF and the liters of the solution:

Moles LiF -Molar mass: 25.939g/mol-:

2.39g * (1mol / 25.939g) = 0.0921moles

Liters solution:

450mL * (1L / 1000mL) = 0.450L

Molarity is:

Explanation:

Answer: d. Water is the most abundant atom in Earth’s atmosphere.

Explanation:

Water percentage in the atmosphere is 0.001 percent only as it not the major reservoir or source of water. The water is available in the atmosphere in the form of water vapors. These water vapors when aggregate and their concentration becomes high they fall down as rain on earth so the rain is collected in water reservoirs like oceans, rivers, lakes, ponds, aquifers, and other sources of water, which are the components of hydrosphere on earth. So, hydrosphere is most abundant in water. Moreover, water is not an atom instead it is the molecule formed by the combination of two molecules of hydrogen and one molecule of oxygen.

fossil fuels are an  nonrenewable resource that people are hoping to replace with renewable resources

Explanation:

Answer:

25.35%

Explanation:

Again let me restate the the equation of the reaction;

H2O (ℓ) + 2 MnO4 - (aq) + 3 CN- (aq) → 2 MnO2 (s) + 3 CNO- (aq) + 2 OH- (aq)

Amount of potassium permanganate  reacted = 10.2/1000 * 0.08035 = 8.1957 * 10^-4 moles

If 2 moles of MnO4 - reacts with 3 moles of CN-

8.1957 * 10^-4 moles of MnO4 - reacts with 8.1957 * 10^-4 * 3/2

= 1.229 * 10^-3 moles of CN-

Mass of CN- reacted = 1.229 * 10^-3 moles of CN- * 26.02 g/mol

= 0.03 g

Hence, percentage of the cyanide = 0.03 g/0.1183 g * 100

= 25.35%

Answer:

n = 0.19 mol

Explanation:

Given mass = 15 g

The molar mass of AsH₃ = 77.94 g/mol

We need to find the number of moles in 15 g of AsH₃. We know that,

No. of moles = given mass/molar mass

[tex]n=\dfrac{15}{77.94 }\\\\n=0.19\ mol[/tex]

So, there are 0.19 g/mol. Hence, the correct option is equal to 0.19 mol.

Answer:

A potential

Explanation:

potential energy is a kind of energy which rest or stays in one position

The objects rest on a position has a potential energy. The bow and arrow that was just pulled back but not yet released has energy has potential energy.

The potential energy of an object is generated by virtue of its position at height above the surface. It is the stored form of energy when the object is at rest. Whereas, kinetic energy of an object is generated by virtue of its motion.

When the object starts to move with a speed, its potential energy starts to convert into kinetic energy. Both are dependent on the mass of the object. And these energies are directly proportional to the mass.

Here, the bow and arrow are not moving with a speed they just pulled and stay on a position, so they don't have a net kinetic energy but they possess a potential energy. Hence, option A is  correct.
