Which ion with a

Chemistry
1 answer:
DiKsa [7]3 years ago
8 0

Answer:

atomic # 38 or strontium (Sr)

Explanation:

Which ion with a

+2charge has the electron configuration

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6?

ADD THE ELECTRONS AND ADD 2 MORE  FOR THE +2 CHARGE

so

2 +2 +6 +2 +6 +2 + 10 +  6 +2  

so if it is now neutral (you added 2 e's to ofsetr the +2 charge) it has 38

protons, so it is atomic # 38 or strontium (Sr)

As electricity flows through a copper wire, the temperature of the wire increases. Some parts of the wire get warmer than others
mezya [45]

Answer:

Conduction

Explanation:

The heat can be transferred in the substances in three ways: conduction, convection, and radiation.

The conduction happens inside the material, usually a solid, and the heat flows as the molecules of the substance are agitated. The convection happens when there are different substances in touch, so it is the heat passage from a solid to a liquid or gas, from a gas to a liquid or vice versa. The radiation occurs between substances that are far away and the heat flows by electromagnetic waves.

Thus, in the wire, the heat flows by conduction.

What is the percent of S in
ollegr [7]

The percentage of the sulfur (S) in the compound CuSO₄ is 20.1 %.

<h3>What is the mass percentage?</h3>

The percentage of an element in a compound can be determined as the number of parts by mass of that element present in 100 parts by mass of the given compound.

First, calculate the molecular mass of the given compound by the addition of the atomic masses of all the present elements in the molecular formula. Then, the percentage of the elements can be determined by dividing the total mass of the element by the molar mass of the compound multiplied by 100.

Given, the atomic mass of copper, sulfur, and oxygen is 63.55 g, 32.07 g, and 16.0g respectively.

The molecular mass of CuSO₄ =  63.55 + 32.07 + 4(16.0)  = 159.62 g

The mass percentage of the sulphur = (32.07/159.62) × 100 = 20.1 %

Therefore, the mass percentage of the sulfur is equal to 20.1 %.
