Why does simple molecular substances have no electrical conductivity?
For something to conduct electricity, it must have two properties: 1. Free moving particles. 2. Charged particles. Simple covalent molecules have neither properties and so it cannot conduct electricity.
How many characteristic properties of 2 substances must be different for the two substances to be different?
1
Where do you look to find the charge on an atom?
I found one. Look in the "Related Links" section for the web address. Notice, however, that it does not have any other info, such as mass or other properties.
What is the oxidation state of Hg?
The oxidation state of S in HgS is -2. Since Hg is +2, to make a neutral charge S must be -2.
Why the formula of magnesium is MgCl2?
Magnesium chloride is an neutral ionic compound. In neutral ionic compounds, the positive charge of the cations must balance out the negative charge of the anions. In the case of magnesium chloride, magnesium is the cation with an ionic charge of +2 and chlorine is the anion with an ionic charge (each) of -1. Since two chlorine anions together have a charge of -2 total, they balance out the one magnesium cation with a charge of +2.
What is the charge on the lead ion in PbS2?
Lead being a transition metal has two possible charges: +2 or +4.

How do you test the thermal insulating properties of three different fabrics when wet and when dry one of the fabrics must be denim?
well heres what you do 1.get 3 empty tins cover them in the test fabrics put thermomoters in them cover the tops and bottoms of the jars in polystyreen test the temp. every 2 mins
What chemical properties are similar to calcium?
Both metals can lose two electrons and both metals form ions with a 2+ charge.
How does an ion with a charge of 2 form?
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
What charge is copper 2 solphide?
Copper II sulphate has variable valency properties, which translates to variable charges.
What is the law relating force between electrical charges and their separation?
Coulumbs law F=k.Q1.Q2 / r^2 Q1= one test charge Q2= second test charge

Can you detect the end of the life of a car battery?
You can do a load test on a battery and compare it to the reserve capacity and cold cranking amps. If it is lower then the ratings then the battery is going bad. Keep in mind that the battery must be charged to its maximum capacity to have an accurate test. Trickle charge on 2 to 6 amps for approx. 6 hours then test battery
What particle has a -3 charge and 36 electrons?
a bromine ion will have 36 electrons and a -1 charge
