Hey, for #1, it's 1, 1, 1 because it's already balanced!

For #2, it's 1, 2, 1, 1 since the product side has 2 Cl's but left side only had 1.

The first one is balanced so you do not have to worry about the coefficients in front of the elements. on the second one, add a 2 in front of the HCl on the left side and you will be balanced. have a great day! :)

An atom has 2 protons in its nucleus . Which of the following must be true for this atom to have no net electrical charge
ehidna [41]
If an atom has 2 protons, then it must also have 2 electrons for there to be no charge. An extra electron will cause for you to have a negative charge, and if you have more protons than electrons, then you will have a positive charge. :)

You have 55 grams of glucose(C6H12O6). How many grams of oxygen do you have?
zubka84 [21]

Answer:

Mass of oxygen in glucose = 29.3g

Explanation:

Mass of glucose given is 55grams.

We are to find the mass of oxygen in this compound.

In the compound we have 6 atoms of oxygen.

Solution

To find the mass of oxygen in glucose, we calculate the formula mass of glucose. We now divide the formula mass of the oxygen atom with that of the glucose and multiply by the given mass to find the unkown mass.

Atomic mass of C = 12g

                           H = 1g

                           O = 16g

Formula mass of C₆H₁₂O₆ = {(12x6) + (1x12) + (16x6)} = 180

             Mass of O in glucose = \frac{6x16}{180}  x 55

                                                  = \frac{96}{180} x 55

                                                  = 0.53 x 55

            Mass of oxygen in glucose = 29.3g
