Answer:

B 2Li + Cl2 ---> 2LiCl

Explanation:

There are 2 Li atoms and 2 Cl atoms on both sides of the equation.

To see if mass has been conserved during a chemical reaction you must look that there is the same amount of each element on both sides.  

Let's look at option A

S_{8} + F_{2} → SF_{6}

We start off with 8 Sulfurs and 2 Florine. This means that we must end up with 8 Sulfurs and 2 Florine  As you can see this is not the case. We only have 1 Sulfur and 6 Florine. This means this chemical reaction is not balanced and does not show conservation of mass.

Let's look at option B

2Li + Cl_{2} → 2LiCl

We start off with 2 Li and 2 Cl. This means that we must, again end up with 2 Li and 2 Cl. As we can see this is the case! This equation is balanced and shows conservation of mass. This is you answer!!!

I only did the work up until the answer (B.). Let me know if you need me to explain why C. and D aren't the answer.

Describe the protons, electrons, and neutrons of an atom of hydrogen-2.
AlladinOne [14]

Answer:

However, various hydrogen isotopes, such as H-2, have one proton and one neutron; H-3 has one proton and two neutrons, etc. The sum of the protons and neutrons in an atom's nucleus is its atomic mass. Thus, the atomic mass of the H-2 isotope is two, the atomic mass of the H-3 isotope is three, and so forth.

Chloroform is a liquid once used for anesthetic. What is the volume of 5.0 g of chloroform? The density of chloroform 1.49 g/mL
mario62 [17]

Answer:

3.3557047 mL

Explanation:

The density can be found using the following formula:

d=\frac{m}{v}

Let's rearrange the formula to find the volume, v.

d*v=\frac{m}{v}*v

d*v=m

\frac{d*v}{d} =\frac{m}{d}

v=\frac{m}{d}

The volume can be found by dividing the mass by the density. The mass of the chloroform is 5 grams and the density is 1.49 grams per milliliter. Therefore,

m= 5g \\d= 1.49 g/mL

Substitute the values into the formula.

v=\frac{5g}{1.49 g/mL}

Divide. When we divide, the grams, or g, in the numerator and denominator will cancel out.

v= \frac{5}{1.49}mL

v=3.3557047 mL

The volume of 5 grams of chloroform is 3.3557047 milliliters

You are at home in your air conditioned garage. You are planning a family road trip from New York to Florida. You are lnfating t
Ksenya-84 [330]
Hello!

According to the Charles' Law, the volume of a gas is proportional to temperature when pressure is constant. When going from New York to Florida, if the pressure is left constant the volume of the tires will increase.

The final volume of the tires can be calculated from the following equation, derived from Charles' Law:

V2= \frac{V1}{T1}*T2=\frac{10 L}{10degC}*32degC=32 L

Have a nice day!

The empirical formula of glucose is CH2O the molecular formula of glucose is 6 times than the empirical formula. what is the mol
jeka57 [31]

Answer:

The molecular formula of glucose is C₆H₁₂O₆

Explanation:

Empirical formula:

It is the simplest formula gives the ratio of smallest whole number of atoms.

Molecular formula:

It gives the total number of atoms in a molecule of compound.

The molecular formula and empirical formula can be related as follow:

Molecular formula = n × empirical formula

Given data:

Empirical formula = CH₂O

Molecular formula = ?

It is stated in given problem that molecular formula is the 6 times of the empirical formula.

Molecular formula = n × empirical formula

Molecular formula = 6 × CH₂O

Molecular formula = C₆H₁₂O₆

The molecular formula of glucose is C₆H₁₂O₆.
