<u>Answer:</u> The balanced chemical equation is given below.
<u>Explanation:</u>
Double-displacement reaction is defined as the reaction in which exchange of ions takes place. The general equation representing this reaction follows:
![AB+CD\rightarrow CB+AD](https://tex.z-dn.net/?f=AB%2BCD%5Crightarrow%20CB%2BAD)
The balanced chemical equation for the reaction of barium hydroxide and perchloric acid follows:
![Ba(OH)_2(aq.)+2HClO_4(aq.)\rightarrow Ba(ClO_4)_2(aq.)+2H_2O(l)](https://tex.z-dn.net/?f=Ba%28OH%29_2%28aq.%29%2B2HClO_4%28aq.%29%5Crightarrow%20Ba%28ClO_4%29_2%28aq.%29%2B2H_2O%28l%29)
By Stoichiometry of the reaction:
1 mole of barium hydroxide reacts with 2 moles of perchloric acid to produce 1 mole of barium chlorate and 2 moles of water molecule.
Hence, the balanced chemical equation is given above.
Answer:
The boiling point of noble gas increases as you go down the group because the London dispersion forces increase.
Answer: Atmosphere
Explanation:
if a scientist wants to predict the weather, they should most directly study Atmosphere.
Answer:
Confusion is eliminated when the correct measurement is applied
Explanation:
A measurement standard is often described as the reference to which other measurements are judged or based on. Most times, measurement standard are used to determine how accurate an experimental measurement is.
A measurement standard may not eliminate confusion when the correct measurement is applied. If the scientist does not agree with the measurement standard being used, then problem will set in.
