Explanation:

the rotation of the earth is what expose different areas to receive sunlight which causes daytime whilst, the other side is facing away which causes night time.

Answer:The Sun rotates around the Earth as it revolves to cause day and night. The Sun revolves around the Earth as it rotates to cause day and night.

Explanation:it just does

The correct option is Shift it toward the side with higher total mole concentration.

Le Châtelier's principle is an observation about the chemical equilibria of reactions. It states that changes in the temperature, pressure, volume, or concentration of a system will result in predictable and opposing changes in the system in order to achieve a new equilibrium state.

If the concentration of reactant increases, the equilibrium will shift toward the side with a higher total mole concentration to maintain the equilibrium.

Hence, the correct option is to Shift it toward the side with a higher total mole concentration.

Explanation:

Answer:

2.05moles

Explanation:

The balanced chemical equation in this question is as follows;

Sn + 2H2SO4 → SnSO4 + SO2 + 2H2O

Based on the above equation, 2 moles of H2SO4 reacted to produce 1 mole of SnSO4

However, the mass of SnSO4 produced is 219.65 grams. Using mole = mass/molar mass, we can find the number of moles of SnSO4 produced.

Molar mass of SnSO4 where Sn = 118.7, S = 32, O = 16

= 118.7 + 32 + 16(4)

= 150.7 + 64

= 214.7g/mol

mole = 219.65/214.7

mole = 1.023mol

Therefore, if 2 moles of H2SO4 reacted to produce 1 mole of SnSO4

1.023 mol of SnSO4 produced will cause: 1.023 × 2/1

= 2.046moles of H2SO4 to react.

Answer:

132.0grams

Explanation:

The formula mass of a compound/molecule is calculated by summing the atomic masses of each individual atom in that compound or molecule.

According to this question, the gram-formula mass of CO2 is given as 44g i.e. by adding 12g of C and 2 × 16g of O. 3CO2 means that 3 moles of the same CO2 molecule.

To find the gram-formula mass of 3 moles of CO2, the following formula is used:

Since 1 mol of CO2 contains a formula mass of 44g

3 moles of CO2 (3CO2) will contain 3 × 44g = 132g of CO2.

The electronic configuration is used to explain the orbitals of an atom and it helps to determine the physical and chemical properties of the elements. The electronic configuration of zinc is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰. The correct option is C.

The distribution of electrons in the atomic orbitals is given by the electronic configuration. It is a standard notation in which all the electrons holding atomic subshells are arranged in a sequence. Each element has a unique electronic configuration.

The electronic configuration of an element can be written in two ways, in standard notation, and in condensed form. In the case of elements with larger atomic numbers, the electronic configuration becomes lengthy in standard notation. So in such cases condensed form is generally used.

In condensed form electronic configuration of zinc is [Ar] 3d¹⁰4s² and in standard form it is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰.

Thus the correct option is C.

Explanation:

Based on the reaction, 1 mole of methane produce 2 moles of water.

To solve this question we must find the molar mass of methane in order to find the moles of methane added. With the moles of methane and the chemical equation we can find the moles of water produced and its mass:

Molar mass CH₄:

1C = 12g/mol*1

4H = 1g/mol*4

12g/mol + 4g/mol = 16g/mol

Moles methane:

24g CH₄ * (1mol / 16g) = 1.5 moles methane

Moles water:

1.5moles CH₄ * (2mol H₂O / 1mol CH₄) = 3.0moles H₂O

Molar mass water:

2H = 1g/mol*2

1O = 16g/mol*1

2g/mol + 16g/mol = 18g/mol

Mass water:

3.0moles H₂O * (18g / mol) =

Answer:

To separate the components, a water wash may be attempted to remove benzoic acid, but benzoic acid is not particularly water-soluble due to its nonpolar aromatic ring, and only small amounts would be extracted into the aqueous layer

The method that can be used to separate Benzoic acid and potassium carbonate is :  The application of water wash separation method

Benzoic acid is slightly soluble in cold water but becomes more soluble as the temperature of water is increased. Water wash separation method is a methodology used for the selective removal of unwanted compounds in a mixture.

The separation of benzoic acid and potassium carbonate is based on the solubility differences between Benzoic acid and potassium carbonate when dissolved in a solvent ( water ) therefore the water wash separation method is the most effective method.

Hence we can conclude that The method that can be used to separate Benzoic acid and potassium carbonate is :  The application of water wash separation method.

Complete question: Luisa likes to drink water from a plastic bottle. She knows the bottles were formed from synthetic polymers that were created in a chemical reaction. She also knows that synthetic materials can cause problems. Which statement explains the kind of problem that can develop from using synthetic materials such as plastics?

a) plastics have changed the way people use materials

b) plastics have made the lives of people easier

c) plastics have contributed to more pollution

d) plastics have made more work for people

Answer: The correct statement is plastics have contributed to more pollution. Option C.

Explanation:

Synthetic polymers are commonly called plastics. These are referred to as synthetic materials which can be softened by heat or pressure and then moulded into any desirable shape like the the plastic bottle Luisa drank from.

The raw materials for the manufacture of plastics are readily and cheaply available for the refinement of crude oil through series of chemical reactions. They are made by polymerization of monomers which are derived from petrochemicals.

Although they are used in producing materials used daily, it has contributed to more pollution over the years. POLLUTION is the release of chemicals or substances through man's activities, into the environment which causes harm to both man and the environment.

Plastics have contributed to more pollution because most plastics are non- biodegradable and cannot be broken down by microbial action into simple inorganic forms. Therefore, they cause severe land pollution problems since they are not easily disposable. Also is poses a major problem to the world supply of crude oil as it's limited. This is as a result of heavy dependence on crude oil which provides petrochemicals that is the bulk of the raw materials needed for making plastics.

Lemon is an acidic fruit with a pH ranging 2 to 3. The acid in lemons are citric acid which makes lemon tart, which is Vitamin C.

Answer:

The  partial pressure of oxygen in the mixture is 296 mmHg.

Explanation:

The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone.

This relationship is due to the assumption that there are no attractive forces between the gases.

So, in this case, the total pressure is:

PT=Phelium + Pnitrogen + Poxygen

You know:

Replacing:

756 mmHg= 122 mmHg + 338 mmHg + Poxygen

Solving:

756 mmHg - 122 mmHg - 338 mmHg = Poxygen

Poxygen= 296 mmHg

The  partial pressure of oxygen in the mixture is 296 mmHg.

I'm assuming you need to label above the lines. So, above the line where the  Cretaceous period ends is mass extinction and where the bracket lies is adaptive radiation.

Explanation:

Mass extinctions are periods of time where the organisms are essentially wiped out in an extremely brief period of time. You can see how the species just drops off. Adaptive radiation occurs when there is a diversification of a group of organisms as evident by the rise in the number of marine animal groups shown by the bracketed area.
