What occurs when an atom of chlorine forms a chloride ion?
dimulka [17.4K]
The answer is B. The chlorine has 7 electrons at the outer shell. So it will gain one electron to become stable when forms a chloride ion. And the gained electron will stay at the outer shell. So the radius becomes larger.

Using the reaction mixture in Problem 1, a student found that it took 230 seconds for the color of the I2 to disappear.
MakcuM [25]
The reaction mixture of problem 1 includes <span>10mL of 4.0 M acetone = 10 mL 1.0 M HCl = 10 mL 0.0050 M I2 = 20 mL H2O. if this is true then the procedure is the following:

In order to find the total volume of reaction then you need to do like this: 
</span><span>V = 10 mL + 10 mL + 10 mL + 20 mL = 50 mL </span>
<span>[I2]o = (0.005 mol I2 / 1 L I2 solution) (10 mL I2 solution) / 50 mL = 0.001 M </span>
<span>To first order, the reaction rate is 0.001 M / 230 s = 4,3 e-6 M/s 
Then if you want to find the rate yoe need to use the following formula:
</span><span> k [CO(CH3)2]^a [I2]^b [HCl]^c 
</span>So: <span>4,3 e-6 = k (4 M * 10 mL / 50 mL)^a (1e-3 M)^b (1 M * 10 mL / 50 mL)^c

A substance has a atomic number of 80.How many protons and electrons do atoms of the substance have ?what is the substance
Anarel [89]

Answer: Substance is Mercury (Hg)

              number of protons = 80

              number of electrons = 80

Explanation:

Atomic number which is symbolized by "Z" is the number of protons in nucleus of an atom.

Hence,

     number of protons = atomic number = 80

  • By knowing atomic number, we can find the element by using periodic table. Since the atomic number 80, the element is Mercury (Hg).

If the substance is in its neutral state, which means there is no charge on it, then the number of protons equals to the number of electrons of that element.

Hence,

   number of electrons = number of protons = 80

What mass, in grams, of bromine gas (Br2) is contained in a 15.7-liter tank at 24.6 degrees Celsius and 0.986 atmospheres? Show
Nezavi [6.7K]

PV = nRT

P is pressure, V is volume, n is number of moles, R is the gas constant, T is temperature in K

(2.85 atm)(12.5 L) = (n)(.08206)(27 C + 273)

n = 1.45 moles x 35.45 grams / mol Cl2 = 51.3 grams
