Answer: Thus the correct coefficient for sodium chloride is 2.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical reaction is:

Pb(NO_3)_2(aq)+2NaCl(aq)\rightarrow PbCl_2(s)+2NaNO_3(aq)

Thus the correct coefficient for sodium chloride is 2.

how many grams of F2 are needed to react with 3.50 grams of Cl2 Equation needed for question- Cl2+3F2-->2ClF3 please explain
pshichka [43]

Answer:

5.62 g of F2

Explanation:

We have to start with the chemical reaction:

Cl_2~+~3F_2~-->~2ClF_3

<u>We have a balanced reaction</u>, so we can continue with the <u>mol calculation</u>. For this, we need to know the <u>molar mass</u> of Cl_2  (70.906 g/mol), so:

3.5~&#10;g~Cl_2&#10;\frac{1~mol~Cl_2}{70.906~g~Cl_2}=0.049~mol~Cl_2

Now, with the <u>molar ratio</u> between Cl_2  and F_2  we can convert from moles of Cl_2  and F_2  (1:3), so:

0.049~mol~Cl_2\frac{3~mol~F_2}{1~mol~Cl_2}=0.148~mol~F_2

Finally, with the <u>molar mass</u> of F_2 we can calculate the gram of F_2 (37.99 g/mol), so:

0.148~mol~F_2\frac{37.99~g~F_2}{1~mol~F_2}=5.62~g~F_2

I hope it helps!

How can a charged atom (an ion) attract a neutral atom? 1. the charged atom can hit the neutral atom and make it positively char
Ivan
The answer would be 2. <span>an ion polarizes a nearby neutral atom, so that the part of the atom nearer to the ion acquires a charge opposite to the charge of the ion, and the part of the atom farther from the ion acquires a charge of the same sign as the ion

In neutral atoms, the negative and positive charge spread evenly. The charge from an ion could create an electric field that will attract the charge of the neutral atoms.
The neutral atoms charge sum still zero, but the distribution of charge could be changed.</span>
