Suppose Earth’s gravitational force were decreased by half. How would this change affect a game of basketball? Think about the motion of the players and the ball.

Answers

Answer:

Due to the decrease in the gravitational force, it will take longer time for ball to reach the ground while dribbling. Moreover, the hang time of players will also be longer. This means that the players will stay on air longer and will be able to jump higher.

Scientists say that photosynthesis and cellular respiration create a cycle that is essential to almost all life on Earth. Use your knowledge of these processes to explain how an oil spill that kills a large percentage of the photosynthetic organisms living in the ocean could affect humans.​

Answers

Answer:

Explanation:

An oil spill is a catastrophic event in the environment. It can negatively affect both plants and wildlife while causing human suffering and economic losses. An oil spill needn't be on the scale of the Exxon Valdez or Deepwater Horizon disasters. The U.S. Environmental Protection Agency (EPA) estimates that 200 million gallons of used oil are disposed of improperly each year.

Spilled oil floats on the surface of the water, blocking the sunlight, from reaching the plants within the body of water. Spilled oil may also directly coat the leaves of plants -- where most of the work of photosynthesis occurs -- reducing or blocking out sunlight. Without sunlight, plants lack the energy needed to undergo photosynthesis.

An oil spill can impact photosynthesis by reducing water quality. Not only does the presence of oil directly poison the water, but the spill can kill sea life, birdlife and other wildlife that uses an aquatic habitat. A large die-off can increase bacteria levels and lower the pH of a body of water. The reduction in water quality can stress plants, essentially halting photosynthesis.

The Aufbau Principle describes that
O electrons with the same spin cannot occupy the same orbital.
electrons will occupy single orbitals within and energy level before doubling up
electrons fill lower energy levels first before occupying higher energy levels.
O electrons in the same level have the same amount of energy

Answers

Answer:

electrons fill lower energy levels first before occupying higher energy levels.

Explanation:

The Aufbau's principle describes that electrons fill lower energy levels first before occupying higher energy levels.

In writing the electronic configuration of atoms, the Aufbau's principle is one of the most important principles to consider.

It states that "sublevels with with lower energies are filled up before those with higher energies".

Sublevels do not fill up in numerical order.

How to calculate the number of molecules in 18g of H2O

Answers

We, know molecular mass of water is, M = 16 g/mol .

Given mass of water, m = 18 g.

We know, number of moles is given by :

[tex]n = \dfrac{18\ g}{16 \ g/mol}\\\\n = 1.125\ moles[/tex]

Now, 1 mole of any compound contains 6.022 × 10²³ molecules.

So, number of moles in 1.125 moles of water is 1.125 × 6.022 × 10²³ =

6.77 × 10²³ molecules.

Hence, this is the required solution.

What is the empirical formula for the following molecular formula: C10H5O2

Answers

The empirical formula is the same as the molecular formula : C₁₀H₅O₂

Further explanation

Given

Molecular formula : C₁₀H₅O₂

Required

The empirical formula

Solution

The empirical formula (EF) is the smallest comparison of atoms of compound forming elements.  

The molecular formula (MF) is a formula that shows the number of atomic elements that make up a compound.  

(empirical formula) n = molecular formula  

(EF)n=MF

(EF)n = C₁₀H₅O₂

If we divide by the number of moles of Oxygen (the smallest) which is 2 then the moles of Hydrogen will be a decimal number (not whole), which is 2.5, then the empirical formula is the same as the molecular formula

A student increases the temperature of a 673 cm^3 balloon from 275 K to 460 K.

Assuming constant pressure, what should the new volume of the balloon be?

Round your answer to one decimal place.

Answers

Answer:

1125.75 cm³

Explanation:

We are given;

Initial volume; V1 = 673 cm³

Initial temperature; T1 = 275 K

Final temperature; T2 = 460 K

From Charles law, we can find the new volume from;

V1/T1 = V2/T2

V2 = (V1 × T2)/T1

V2 = (673 × 460)/275

V2 = 1125.75 cm³

At the heart of the stars, nuclear fusion merges _____ together in the nucleus of atoms to create new elements?

Answers

Answer:

lighter atoms especially hydrogen

Explanation:

At the heart of the stars, nuclear fusion merges lighter atoms especially hydrogen together in the nucleus of atoms to create new elements.

During nuclear fusion small atomic nuclei combines to form larger ones with the release of a large amount of energy.

The energy released provides the needed temperature for another set of hydrogen atoms to fuse. This process is in turn yields another set of helium atom which releases a lot of energy.

A chain reaction progresses which leads to the formation of new elements.

Answers

Answer:

2.86L

Explanation:

Given parameters:

V1  = 2.1L

T1  = 200°C  = 200 + 273  = 473K

T 2  = 370°C  = 370 + 273  = 643K

Unknown:

V2  = ?

Solution:

Since pressure is constant, we apply the Charles's law;

           [tex]\frac{V1}{T1}[/tex]   =  [tex]\frac{V2}{T2}[/tex]  

V is volume

T is the temperature

1 is the initial state

2 is the new state

                [tex]\frac{2.1}{473}[/tex]    = [tex]\frac{V2}{643}[/tex]  

                 V2  = 2.86L

Which of the following atoms would have a charge of +1?
An atom with 9 protons, 9 electrons, and 9 neutrons
An atom with 7 protons, 11 electrons, and 8 neutrons
An atom with 5 protons, 5 electrons, and 4 neutrons.
An atom with 6 protons, 5 electrons, and 7 neutrons

Answers

Answer: An atom with 6 protons, 5 electrons, and 7 neutrons

Explanation: In this case, neutrons do not matter as they have a charge of 0, or no charge. A proton has a charge of +1 and an electron has a charge of -1. Since there are 6 protons, the total charge of the protons would be +6. Since there are 5 electrons the total charge of the electrons would be -5. +6 - 5 would result in a charge of +1. This means that this atom would have an overall charge of + 1. Basically, if there is one more proton than electron, then the overall charge of the atom will be +1 but if there is one more electron than proton, then the overall charge of the atom will be -1.

Complete the following sentence: In a reaction containing two reactants, if one of the reactants is in excess, the other reactant is known as the ______ reactant.

Answers

Answer:

excess reactant

Explanation:

The excess reactant is the reactant in a chemical reaction with a greater amount than necessary to react completely with the limiting reactant. It is the reactant(s) that remain after a chemical reaction has reached equilibrium.

In a reaction containing two reactants, if one of the reactants is in excess, the other reactant is known as the limiting reactant which decides the yield of the reaction.

What is limiting reactant ?

In a reaction, all the reactants have to be in correct stoichiometry to complete the reaction. To achieve the mole ratio of the reactants is very much important for the completion of a reaction.

If a reactant is insufficient in amount, then the reaction will stop as soon as this reactant is consumed. Hence, this reactant determine the yield of the product. This reactant which is not in correct stoichiometry for the complete reaction is called the limiting reactant.

The reactant which is excess in quantity thus does not have a role in the yield of the reaction is called the excess reactant. Whatever, the concentration of this reactant in extra, the reaction does not proceed after the consumption of limiting reactant.
