Na2SO4 is the salt that is produced.
If you look at the question, it asking which is produced so the answer must be on the product side of the reaction (to the right of the arrow).
You should also recognize that 2H2O is water, and water is not a salt.
Therefore the only other choice is Na2SO4.
Answer: The sun
Explanation:
its the real boss of the water cycle, and it doesn't even live here on Earth. The sun provides heat, or energy, which is what makes the water cycle work. The sun's heat allows water to change forms from liquid to gas to ice and back again.
Answer: Steel wool turns from a gray color to a reddish color after it gets wet and then sits on a counter is a sign of chemical change.
Explanation:
A change that brings change in chemical composition of a substance is called a chemical change.
For example, Steel wool turns from a gray color to a reddish color after it gets wet and then sits on a counter is a chemical change.
This is because steel wool is mostly made up of iron and when iron becomes wet then in the presence of air it gets oxidized and therefore, it gets corroded.
This corrosion appears as reddish color of steel wool and it represents a chemical change has occurred in the steel wool.
Thus, we can conclude that steel wool turns from a gray color to a reddish color after it gets wet and then sits on a counter is a sign of chemical change.
Answer:
This is because, Kelvins and Celcius degrees both agree at fixed points i.e; the lower fixed point and upper
Hello, let me break this down for you! :)
A is your energy of your reactants, B is your activation energy, so the
total value could be found from B-Y. C is the value of your energy of
your products. X is your delta H value. So in this, your products are
higher energy than the reactants, so H is + and e2-E1 is positive so E2
>E1
Therefore your answers would just be <span>E2 > E1 and
</span><span>Hrxn<span> is positive.
Hope this helps! If you have any other questions or need further explanation just let me know! :)
