Answer:
water because the other two were formed through a chemical process
Answer: It is causing erosion, landslides, and craters. If this keeps up the ice in the artic will eventually be gone
Explanation:
Answer:
CH₄ + 2O₂ → 2H₂O + CO₂
Explanation:
From the given problem;
White balls = hydrogen
Black balls = carbon
Gray balls = oxygen
Equation of the reaction:
1 carbon atom surrounded by 4 hydrogen + 2 oxygen molecules gives two hydrogen atoms bonded to one oxygen + 1 carbon atom bonded to two oxygen
CH₄ + 2O₂ → 2H₂O + CO₂
The reaction above is balanced.
Answer:
Separating funnel is used to separate the mixture of two immiscible liquids. Kerosene oil and water do not mix with each other and form two separate layers. The mixture separates into two layers according to their densities.

Let us assume that there is a 100g sample present. The respective mass of each element will then be:
C: 74 g
H: 7.4 g
N: 8.6 g
O: 10 g
Now, we divide each constituent's mass by its Mr to obtain the moles of each
C: (74 / 12) = 6.17
H: (7.4 / 1) = 7.4
N: (8.6 / 14) = 0.61
O: (10 / 16) = 0.625
Dividing by the smallest number:
C: 10
H: 12
N: 1
O: 1
Thus, the empirical formula is
C10H12NO
