Provide a balanced equation for the reaction between lead nitrate and sodium chloride

Answers

Answer:

Pb(NO3)2 + 2NaCl = PbCl2 + 2NaNO3

Explanation:

Lead nitrate is Pb(NO3)2

Sodium Chloride is NaCl

The basic reaction is:

Pb(NO3)2 + NaCl = PbCl2 + NaNO3

Now we need to balance the equation. Note that the lead nitrate contributes 2 (NO3) units, but there is only 1 NO3 on the product side. So start by adding a second NaNO3:

Pb(NO3)2 + NaCl = PbCl2 + 2NaNO3

Now we have 2 Na atoms on the right side, so add a "2" to the NaCl:

Pb(NO3)2 + 2NaCl = PbCl2 + 2NaNO3

This is starting to look good. Lets check the atom/unit counts on both sides of the equation:

Reactants Products

Pb 1 1

NO3 2 2

Na 2 2

Cl 2 2

The equation is now balanced. Pb(NO3)2 + 2NaCl = PbCl2 + 2NaNO3

Why should you cover the container during chromatography?

Answers

Typically the solvent used for the chromatography is rather volatile. So, its likely that the entire solvent will evaporate prior to the completion of the chromatography if the container isn't covered.

CaCO3---> CaO+CO2 How many moles of CaO form when 98.60g CaCO3 decompose? 98.60g CaCO3= ______ mol CaO

Answers

Answer:

0.9852 moles of CaO

Explanation:

Reaction equation for the decomposition of CaCO₃:

CaCO₃ → CaO + CO₂

The question asks how many moles of CaO form when 98.60g of CaCO₃ decompose.

We can see from the reaction equation that for every mol of CaCO₃, one mol of CaO will be produced (molar ratio 1:1)

_____________________________________________________

So first we need to calculate how many moles are the 98.60g of CaCO₃:

Molar Mass of CaCO₃ = molar mass Ca + molar mass C + 3 * molar mass O

= 40.078 + 12.011 + 3 * 15.999 = 100.086 g/mol

Moles of CaCO₃ = mass CaCO₃ / molar mass CaCO₃

Moles of CaCO₃ = 98.60 g / 100.086 g/mol = 0.9852 moles CaCO₃

________________________________________________________

As we said before for every mol of CaCO₃, one mol of CaO is produced.

So the decomposition of 0.9852 moles of CaCO₃ will produce 0.9852 moles of CaO.

Hey I think it is going to be 0986 moles. Cuz we can see that no. of moles of CaCO3 which will decompose is equivalent to the no. of CaO . Now it's just the matter of finding the no. of moles of CaCO3 .

no.of moles=mass /relative molecular mass

Which change occurs during a nuclear fission reaction? (1) Covalent bonds are converted to ionic bonds.
(2) Isotopes are converted to isomers.
(3) Temperature is converted to mass.
(4) Matter is converted to energy

Answers

Answer;

Matter is converted to energy

Explanation;

Nuclear fission is a type of nuclear reaction in which a nuclei of an atom splits or breaks down into two or more smaller nuclei.
It involves subdivision of heavy nucleus of an atom such as Uranium into two or more fragments which has almost the same equal mass.
Nuclear fission is accompanied by release of large amount of energy, thus we can say that matter is converted to energy.
