Answer:
reflection
Explanation:
the moon reflects sunlight causing it to look brighter. the sun is not a medium as light doesn't require a. medium to travel. nor is a moon concave...
hope it helps
Yes, it will be worthwhile to investigate finding a catalyst to use in this reaction under standard conditions because it is negative.
<h3>What is a Catalyst?</h3>
This is a substance which speeds up the rate of a chemical reaction by lowering the activation energy.
ΔG being negative indicates a a slow reaction which is why a catalyst under standard conditions should be used.

Answer:
2+
Explanation:
The charge on Z in the compound ZB₂ is a 2+
From the given compound:
We know that Br is bromine with a charge of -1;
So;
Using the combining power approach:
Atoms Z Br
Combining power 2 1
Exchange of valency 1 2
So;
The charge on Z is 2+

Answer: The original volume in liters was 0.0707L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 0.85 atm
= final pressure of gas = 456 mm Hg = 0.60 atm (760mmHg=1atm)
= initial volume of gas = ?
= final volume of gas = 94.0 ml
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
(1L=1000ml)
Thus the original volume in liters was 0.0707L
The three substances add up to 105% instead of 100%. Also, <span>the amount of either one of those compounds is more than according to the Stoichiometry of the reaction, meaning one of those compounds is in excess. </span>
