1)gaseous sulfur trioxide and gaseous nitrogen monoxide form when gaseous sulfur dioxide and gaseous nitrogen dioxide react.

2)Enter the formula of the missing substance ( Y ) in the balanced equation below. Do not give the coefficient.
C2H4 + 3Y → 2CO2 + 2H2O

i got number 2 already, just help me with number 1

You don't have a question for #1, just a statement.

it says to write an unbalanced chemical equation that summarizes the statement

1) To determine the products formed when gaseous sulfur dioxide (SO2) and gaseous nitrogen dioxide (NO2) react, we need to examine their chemical formulas. Both SO2 and NO2 are compounds consisting of two elements: sulfur (S) and oxygen (O) for SO2, and nitrogen (N) and oxygen (O) for NO2.

When these two compounds react, they combine to form new compounds. By looking at the reactants, we can see that the sulfur atom from SO2 will combine with the nitrogen atom from NO2, while the oxygen atoms from both compounds will form new molecules as well. The chemical equation can be written as:

SO2 + NO2 → ?

To determine the products, we need to balance the equation based on the Law of Conservation of Mass, which states that matter cannot be created or destroyed during a chemical reaction. In this case, we need to ensure that the number and type of atoms on both sides of the equation are equal.

By balancing the equation, we find:

2SO2 + 2NO2 → 2SO3 + 2NO

Therefore, gaseous sulfur trioxide (SO3) and gaseous nitrogen monoxide (NO) are the products formed when gaseous sulfur dioxide and gaseous nitrogen dioxide react.

2) In the balanced equation C2H4 + 3Y → 2CO2 + 2H2O, we are given the molecular formula of ethene (C2H4) and the products carbon dioxide (CO2) and water (H2O). We need to determine the missing substance labeled Y.

To identify the missing substance, we can examine the balanced equation and compare the number of atoms on both sides. By observing the carbons and hydrogens, we can see that there are already two carbon atoms and four hydrogen atoms on the left side (C2H4). On the right side, there are two carbon atoms and four hydrogen atoms (2CO2 + 2H2O) as well.

Since the numbers of carbon and hydrogen atoms are already balanced, we conclude that the missing substance Y does not contain carbon or hydrogen. Thus, the formula and name of Y cannot be determined without additional information.
