Answer 3

1) To solve the given chemical equation, we need to balance it by ensuring that the number of atoms of each element is the same on both sides of the equation. Let's start by balancing the oxygen atoms.

The equation given is: Mr(H2EO4) = 98

To balance the oxygen atoms, we can see that there are 4 oxygen atoms on the left side of the equation. Therefore, we need to find a compound on the right side that contains 4 oxygen atoms. One such compound is H2O, which contains 2 oxygen atoms. So, we can add 2 H2O molecules to the right side of the equation:

Mr(H2EO4) = 98 Mr(H2O) + Mr(H2O) = 98

Now, let's balance the hydrogen atoms. On the left side, we have 2 hydrogen atoms from the H2EO4 compound. On the right side, we have 4 hydrogen atoms from the H2O molecules. To balance the hydrogen atoms, we can add a coefficient of 2 in front of the H2EO4 compound:

2 Mr(H2EO4) = 98 Mr(H2O) + Mr(H2O) = 98

Now, let's balance the remaining elements, which are E and O. Since we don't have any information about the specific elements, we cannot determine the exact coefficients for them. However, we can still balance the equation by assuming that the coefficients for E and O are both 1. Therefore, the balanced equation becomes:

2 Mr(H2EO4) = 98 Mr(H2O) + Mr(H2O) = 98

This is the balanced equation based on the given information. Please note that without knowing the specific elements and their valences, we cannot determine the exact molecular formula for the compounds involved.

2) The equation given is: Mr(E2O) = 94

To balance this equation, we need to know the specific elements involved and their valences. Without this information, it is not possible to determine the balanced equation. If you can provide more details about the elements and their valences, I would be happy to help you further.

Please note that it is important to provide all the necessary information when asking for help with chemical equations to ensure accurate and meaningful solutions.
