I believe it can be warm because usually the surface below us is warm itself, causing the air to be warm as well. The temperature can vary as well
Answer:
Option D. ZnCl₂ and H₂
Explanation:
From the question given above, the following equation was obtained:
2HCl + Zn —> ZnCl₂ + H₂
Products =?
In a chemical equation, reactants are located on the left side while products are located on the right side i.e
Reactants —> Products
Now, considering the equation from the question i.e
2HCl + Zn —> ZnCl₂ + H₂
The products are ZnCl₂ and H₂ because from our discussion above, we said that products are only located on the right side of chemical equation.
Thus, option D gives the correct answer to the question.
Answer:
Explanation:
The Lanthanides were first discovered in 1787 when a unusual black mineral was found in Ytterby, Sweden. This mineral, now known as Gadolinite, was later separated into the various Lanthanide elements. In 1794, Professor Gadolin obtained yttria, an impure form of yttrium oxide, from the mineral.
Answer:
135 mile marker will the car reach after 2 hours.
Explanation:
Speed of the car = 55 mile/hour
Distance covered in 2 hours = d
The direction of the car is in decreasing marker numbers which mienas that car had started from end where 145 mile marker was present.
So, the marker appearing after travelling 2 hours will be:
145 - 110 = 135
135 mile marker will the car reach after 2 hours.
