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.

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.

Some students believe that teachers are full of hot air. If I inhale 2.1 liters of gas at a temperature of 200 C and it heats to a temperature of 370 C in my lungs, what is the new volume of the gas?

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

When you break an iron magnet into two pieces, you get ____.


two north poles

two south poles

two north poles and two south poles

a piece of iron that is no longer magnetic

Answers

Answer:

two north poles and two south poles

Explanation:

A single magnet has a north pole and a south pole. If it is broken into two pieces, then each of the two pieces will have a north pole and a south pole.

No matter how many times or into how many pieces a magnet is broken, the resulting pieces will have two poles each.

Answer:

Each piece will still have a north pole and a south pole.

how molecules react to an increase in temperature.

Answers

Answer:

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).

Explanation:

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

2.

Explanation:

Beacuse they are all group 1 metals. All have the same boiling, melting point and reactivity due to one electron in its outer shell.

Potassium(k), rubidium(Rb), and cesium(Cs) are the three elements from the given list that have the most similar chemical properties.

Therefore the correct answer is option 2.

What is the atomic number?

The total number of protons present in an atom is known as the atomic number of that atom. The atomic number has no correlation either with the number of neutrons or the number of electrons present inside an atom.

While the atomic mass of an atom is the sum of the total number of protons and the number of neutrons present inside of any atom.

From the list of elements, potassium (k), rubidium (Rb), and cesium (Cs) are the three that share the most chemical similarities.

Thus, option 2 is the right response.

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.

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

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.

You eat a snack that has 190 Calories, how many kilojoules did you consume? PLEAS HELP ME I need the work too pls

Answers

Answer:

794.96 kilojoules

Explanation:

multiply 190 by 4.184

There are 0.798 kilojoules an individual must consume when he/she takes a snack that has 190 Calories.

What is one Calorie?

One calorie may be defined as a unit for measuring heat wjhich is equivalent to the amount of heat required to increase the temperature of one gram of water one degree Celsius.

According to the question,

The amount of calories a snack contains = 190 calories

Now, you should be required to convert calories into Joules.

1 calorie ≅ 4.2 Joules.

190 calories = 190 × 4.2 = 798 Joules.

Now, according to the conversion factor, 1 kilojoule = 1000 joules

798 Joules = 798/1000 = 0.798 kilojoules.

Therefore, there are 0.798 kilojoules an individual must consume when he/she takes a snack that has 190 Calories.

Answers

Answer:

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.
