In order to compute this, we must first take a couple of assumptions of:
1) The laboratory size so we can calculate its volume
2) The number of students working in the lab so we know the total gas produced
Let the lab be
11 m × 9 m × 6 m
The volume then computes to be:
594 m³
We know that
1 Liter is 1 dm³
1 m = 10 dm
1 m³ = 1000 dm³
Therefore, the room volume in liters is:
594,000 Liters
Let there be 30 students in the laboratory
Total gas being produced:
6 × 30
= 180 Liters
This works out to be:
0.03% of Hydrogen by volume
Therefore, there is no risk of explosion given our assumption of size and students.
Answer:
The correct answer is Mn goes from +7 to +2.
Explanation:
The permanganate ion (Mn04-) forming by Oxygen (-2 its oxidation state) and the Mn (+7), throwing the count: +7 + (-2 x4) = -1 (the charge of the ion). Said permanganate ion is reduced in the reaction to Mn2 +.
Explanation:
Carolus Linnaeus was one of the foremost taxonomist that provided an insight into the grouping and classification of organisms.
He came up with the seven groups below;
Species
Genus
Family
Class
Order
Phylum
Kingdom
Organisms belonging to the same species group or taxa can reproduce to produce viable offsprings.
