I’m pretty sure you add, multiply, subtract, & divide
Answer:
<u><em>The correct option is C) the moon takes the same time to rotate and revolve.</em></u>
Explanation:
Scientific experiments have concluded that it takes approximately 23 days for the moon to rotate and also it takes the same duration for the moon to revolve around the Earth. Due to this consistency, the moon appears to be still.
<em>Such synchronization results in the same face of the moon to be directed towards the Earth. Hence, the same craters of the moon will be observed by the scientist every day.</em>
<em></em>
Other options, like option D, is not correct because there will be craters on the other side of the moon too. But as we see the same side of the moon, hence we cannot see the craters present on the other side of the moon.
Answer:
D. The resulting solution does not conduct electricity.
Explanation:
Hello there!
In this case, for the given chemical reaction we can say that:
A. it is true because the nitric acid ionizes into hydrogen and nitrate ions
B. it is a decomposition reaction because the acid is partitioned into the composing ions.
C. it is ionized to hydrogen cations and nitrate anions.
D. this is incorrect because nitric acid is a strong electrolyte able to conduct the electricity.
