Answer:
as an inflammable substance
Explanation:
Because when it reacts with electricity and water start to produce bubbles, and these bubbles burn, that mean is a substance flammable.
Now a days it is needed to have more test to identify a substance and to classify not just by the physical properties, also by the chemical properties and even more, by the chemical behavior in front of other substances.
So to find the limiting reagent and excess reagents you would first convert from grams to moles. From there you would find that the mole to mole ratio of Nitrogen to Hydrogen is 1:3. Then you would find that after using all moles of Nitrogen you would still have 6 moles of Oxygen (I rounded from the beginning). Making Nitrogen the limiting reagent and Hydrogen the excess reagent. Then using atomic weight of Ammonia which is 15.018 g/mole you would figure out how much Ammonia was made by using 54 moles (using ratio) and multiplying that by 15.018 (atomic weight). Then I got 810.972 grams. I’m not sure if this is completely correct but I will include my work to help you.
Answer:
ionic.
Explanation:
the electronegativity difference is greater than 1.7.
You are testing which material keeps the drink warmer for longer in a freezer. You can use a polystyrene cup, plastic cup covered in wool, etc. Put them all in at the same time. Check the temp before and record. Check the temp after 10, 20 and 30 mins of each cup also and record. Compare the before an after temp of every cup using the equation (change in temp / original temp (×100)). Hopefully that helps.
