 <span>The ocean is primarily a liquid and the atmosphere is mostly gas, so they are different states of matter. They also have different chemical compositions which really ought to be common knowledge. Also, very few fish swim in the sky.

An inexpensive and accurate method of measuring the quantity of electricity flowing through a circuit is to pass the current thr
Paha777 [63]

Total of 127.013 C of charge is passed

Given

 weight of Ag solution before current has passed = 1.7854 g

  weight of Ag solution after current has passed = 1.8016 g

  Molecular mass of Ag = 107.86 g

  Faraday's Constant = 96485

First of all we have to apply Faraday's First Law of Electrolysis i.e

         m = ZQ

  where

Z is propotionality constant (g/C)

Q is charge (C)

Hence,

 Z = Atomic mass of substance/ Faraday's Constant

    = \frac{107.86 g}{96485 C}

    = 0.0011178 g/C

Now ,

   change in mass before and after the passing of current (Δm)

       Δm = 1.8016g-1.7854g

             =   0.0162g

    Now  amount of coulombs passed = \frac{0.142g}{0.0011178 g/C }

          amount of coulombs passed = 127.03524 C

Thus from the above conclusion we can say that amount of coulombs have passed is 127.03524 C

How many grams of NaCl are needed in order to make a liter of a 2.00 M NaCl solution? O 58.4 g O 117 g O 2.00 g​
vitfil [10]

Answer:

B.) 117 g

Explanation:

(Step 1)

To find the mass, you need to first find the moles of NaCl using the molarity  ratio.

Molarity = moles / volume (L)

2.00 M = moles / 1.0 L

2.00 = moles

(Step 2)

Now that you know the moles, you can convert it to grams using the molar mass.

Molar Mass (NaCl): 22.990 g/mol + 35.453 g/mol

Molar Mass (NaCl): 58.443 g/mol

2.00 moles NaCl          58.443 g
---------------------------  x  -----------------  =  117 g NaCl
                                        1 mole

A particular isotope of uranium has a nucleus with 92 protons and 143 neutrons identify this isotope in two diffrent ways
inn [45]

Isotopes can represented in two ways. In the first way, the element's symbol is used with mass number at the upper left and atomic number written on the lower left of the symbol. In the other form of representation, the isotope name is written with a dash and mass number.

Given that the isotope has 92 protons. So the atomic number is 92.

The isotope has 143 neutrons

So the mass number = Total number of protons + Neutrons

                                  = 92 + 143 = 235

Therefore, the two ways of representing the isotope is:

1. ^{235}_{92} U

2. Uranium-235

´ Identify the independent, dependent, and controlled variables in your experiment which is how does adding salt affect the free
Margaret [11]
<span>An independent variable is a variable that is not affected in the experiment. It is what experimenter controls. Here, the concentration of salt is the independent variable.
On the other side, a dependent variable is called dependent because it depends on the independent variables. It is what is affected and observed during the experiment. Here, the freezing point of water is affected and, thus, it is the dependent variable.
A controlled variable is a variable that must remain unchanged (must be constant) during the experiment so that the effect on the dependent variable depends only on the independent variable. Here, the volume of water must be constant, so it is the controlled variable.
