Answer:
HBr
Explanation:
Acidity is directly proportional to non metallic character. Moving from left to right and down the group non metallic character increases hence acidic strength increases. Based on this explanation HBr is strongest acid among given compounds.
Answer:
V2 = 17371.43ml
Explanation:
We use Boyles laws
since temperature is constant
P1V1=P2V2
760 x 400 = 17.5 x V2
304000 = 17.5 x V2
V2 = 304000/17.5
V2 = 17371.43ml
Answer:
Magnesium is a naturally ubiquitous; (appearing & found evrywhere) element and has three naturally occurring stable isotopes, 24Mg, 25Mg and 26Mg, with relative abundance of 78.99%, 10.00% and 11.01%, respectively.
However, they differ only because a 24Mg atom has 12 neutrons in its nucleus, a 25Mg atom has 13 neutrons, and a 26Mg has 14 neutrons.
Explanation:
Answer:
0.97014 moles KMnO4
Explanation:
1 g KMnO4 = 0.00633 mol
153.26 g x 0.00633 mol/ 1 g KMnO4 = 0.97014 moles KMnO4
