balance CHCl3 + O2 = CO2 + H2O + Cl2

Answers

Answer:

2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2

Explanation:

Left Hand Side(LHS)

We have CHCl3 and O2

Right Hand Side(RHS)

We have CO2, H2O and Cl2

Balancing

To make sure that they have same values, put 2 before CHCl3 giving 2CHCl3 and 3 on Cl2(RHS) for chlorine gas giving 3Cl2

H2O remains the same

Before CO2 put 2 giving 2CO2

To make sure that oxygen is balanced put 5/2 before it. This gives 5/2 O2 (2 cancels out don't worry)

Combining all;

2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2

I hope this helps. Have a nice studies.

The nucleus of atom is composed of two subatomic particles that each have charges.

Protons, which are positively charged particles.Neutrons, which are neutrally charged particles.

why does magnesium in an aqueous solution of magnesium chloride conduct electricity but solid magnesium chloride does not?

Answers

Answer:

Delocalized electrons

Explanation:

Magnesium Chloride is an ionic compound, so its lattice structure prevents the flow of electrons. However, when you convert the ionic compound into an aqueous solution it allows movement of electrons/ions due to the breakdown of the molecular forces which make it conductible. In short, Ionic compounds as a solid are not conductible but they are in an aqueous form.

Some copper is palced in a previouly weighted crucible and reweighed .
Mass of crucible + copper = 5.92g
Mass of crucible = 4.65g
Clculate the mass of copper used in the experiment

Answers

Answer:  1.27g (mass of Copper)

Explanation:

We can find the mass of copper by finding the difference between the mass of the crucible and the copper, and just the crucible. This is possible since the mass that is left would be attributed to just the copper.

Mass of copper = (Mass of crucible + copper) - Mass of crucible

                          = 5.92 g - 4.65 g

                          = 1.27 g
