What is an ion? Describe and give an example.

Answers

Answer 1
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. An example is Iron (III) , Iron (II) , lithium, and hydrogen.
Answer 2
An ion is an atom molecule that has a net electrical charge

Water flows through a pipe at a rate of 620 gallons every 5 1/2 minutes expressed this rate of flow and cups per second

Answers

620 gallons = 620 x 16 = 9920 cups

5 1/2 minutes = 5 1/2 x 60 = 330 seconds

rate of flow = 9920/330 = 30.06 cups/second

The rate of flow of Water flows through a pipe will be 30 cups per second.

What is the rate of flow?

The distance covered by the particle or the body in an hour is called the rate of flow. It is a scalar quantity. It is the ratio of gallons to time.

We know that the speed formula

Rate of flow = Gallons/Time

Water flows through a pipe at a rate of 620 gallons every 5 1/2 minutes expressed at this rate of flow and cups per second.

We know that in one gallon, there are 16 cups.

5.5 minutes = 330 seconds

The rate of flow will be

Rate of flow = (620 x 16) / 330

Rate of flow = 30 cups per second

The rate of flow of Water flows through a pipe will be 30 cups per second.

valence electrons.

Answers

Answer:

This can be determined by looking at the number of protons.

Explanation:

The atomic number which is the number of protons is the best indicator of what an element is.

Based on the number of protons in an atom, elements are arranged in a definite grouping on the periodic table.

This because, atoms do not readily give off their protons so, it is a good measure of the type of atom one might be dealing with.

A transformer has 150 turns in its primary coil and 50 turns in its secondary coil. If the input voltage is 12 V, what is the output voltage?​

Answers

Answer:

36V

Explanation:

Given parameters:

Number of turns in primary coil  = 150turns

Secondary coil turn = 50turns.

Input voltage  = 12V

Unknown:

Output voltage  = ?

Solution:

For this transformer problem, we use the expression;

   

   [tex]\frac{N_{s} }{N_{p} }[/tex]   = [tex]\frac{V_{s} }{V_{p} }[/tex]  

Insert the parameters and solve;

        Ns is the number of secondary turns

        Np is the number of primary turns

         Vs is the secondary voltage

          Vp is the secondary voltage

Insert the parameters and solve;

          [tex]\frac{150}{50}[/tex]   = Output voltage / 12

          Output voltage = 12 x 3  = 36V

To what pressure must a gas be compressed in order to get into a 3.00 cubic foot
tank the entire weight of a gas that occupies 400.0 cu. ft. at standard pressure?

Answers

Answer:

133.3atm

Explanation:

Given parameters:

Initial volume  = 400ft³

Final volume  = 3ft³

Initial pressure = 1atm

Unknown:

Final pressure  = ?

Solution:

To solve this problem, we  apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".

  Mathematically;

               P₁V₁ = P₂V₂

P and V are pressure and volume

1 and 2 are initial and final states;

   Insert parameters and solve;

                1 x 400  = P₂ x 3

                     P₂  = 133.3atm

Answer:

Combination reaction

Explanation:

In Chemistry, elements and compounds are involved in a process called chemical reactions, which are of different types namely: combination, decomposition, double replacement, combustion etc. A combination reaction is that reaction in which two or more substances called the REACTANTS combine together to form a single new substance called the PRODUCT.

In this case, a reaction is depicted as follows:

2SO2(g) + O2(g) --> 2SO3(g)

In this reaction, compound SO2 combines chemically with element O2 to form a single new compound SO3. Hence, this is a type of COMBINATION REACTION.

Would you expect manganese(II) oxide, MnO, to react more readily with HF(aq) or NaOH(aq)?

Explanation:

The atoms of some elements can be made radioactive by: bombarding them with high energy particles: Choice 3.

Definition:

Radioactivity is a process, (spontaneous) by which the nucleus of an unstable atom loses energy by emitting radiation which may include alpha particles, beta particles, gamma rays and conversion electrons, otherwise known as high energy electrons.

However, radioactivity is observed as a natural occurring process, the phenomenon can also be artificially induced typically via the bombarding atoms of a specific element by radiating particles, thus creating new atoms.
