What is the charge of a hypothetical ion with 85 protons and 87 electrons?

Chemistry

MaRussiya [10]3 years ago

There is a charge of -2 on an ion.
A neutral atom always have equal number of protons and electrons. if an atom loses and electron, an ion gets positive charge and if an atom gains electron it gets negative charge.
An atom with 85 protons means it also have 85 electrons but when it gains two electrons it becomes ion and then the number of electrons is 87. So that is why an ion have -2 charge.

Bingel [31]

Answer:

Gasoline being used in the engine of a car producing exhaust

Explanation:

Hello,

As it is known, gasoline is the component which car engines use to gain energy in order to allow the movement, in such a way, gasoline experiences a combustion chemical reaction, which is a chemical change, induced by the spark that the oxygen provides to allow the combustion. Such chemical process turns both gasoline and oxygen into carbon, nitrogen and sulfur oxides, water, ashes, other side products and the aforesaid energy to move the car.

Best regards.

Mama L [17]

Answer:

Everyone, this is Ricky. And today we're working on Problem 51 from Chapter 22 and we're gonna determine the number of UNP. Aired electrons for the complex island of CEO seal for minus two I first up, let's determine the charge of art metal ion. So cue is our charge plus four minus one, which is a charge of each chloride ion. The overall charge of minus two Hugh is equal to plus two. I hope this will help

Use the following equation to determine how many moles of C are needed to react with 0.500 mole of SO2.
Maru [420]

Answer:

The answer to your question is 1.25 moles of C

Explanation:

Reaction

                                5C  +  2SO₂   ⇒   CS₂  +  4CO

Check that the reaction is balanced

                          Reactant         Element        Product

                                5                   C                   5

                                2                    S                    2

                                4                   O                    4

Use proportions to find the moles of C needed.

                       5 moles of C -----------------  2 moles of SO₂

                       x  moles of C ----------------   0.500 moles of SO₂

                       x = (0.500 x 5) / 2

                       x = 1.25 moles of C
