Answer:
nonpolar covalent
Explanation:
Comparing their electronegativities will help determine the type of bond. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The difference in electronegativity (ΔEN) is used to determine bond type. Hydrogen has an electronegativity of 2.20 and sulfur has 2.58. The difference is 0.38,so the electrons are shared in a nonpolar covalent bond.
Answer:
and 
Explanation:
Our goal for this question is the calculation of the number of moles of the molecules produced by the reaction of hydrazine (
) and <u>oxygen</u> (
). So, we can start with the <u>reaction</u> between these compounds:
Now we can <u>balance the reaction</u>:
In the problem, we have the values for both reagents. Therefore we have to <u>calculate the limiting reagent</u>. Our first step, is to calculate the moles of each compound using the <u>molar masses values</u> (32.04 g/mol for
and 31.99 g/mol for
):


In the balanced reaction we have 1 mol for each reagent (the numbers in front of
and
are 1). Therefore the <u>smallest value would be the limiting reagent</u>, in this case, the limiting reagent is
.
With this in mind, we can calculate the number of moles for each product. In the case of
we have a <u>1:1 molar ratio</u> (1 mol of
is produced by 1 mol of
), so:

We can follow the same logic for the other compound. In the case of
we have a <u>1:2 molar ratio</u> (2 mol of
is produced by 1 mol of
), so:

I hope it helps!
Answer:
vacuum
Explanation:
vacuum is the form by which matter cant exist
That would be an ionic bond since it has electrons to spare, rather than a convalent bond where all the electrons are taken up thus it is not a good conductor
