Answer:
cools as it rises, then sinks back down
Explanation:
The movement of air is a convection current. Convection currents occur when warm air rises, cools down, and sinks due to gained density, replacing the warm air closer to the ground, creating a cycle.
Answer:
D. 6
Explanation:
Each pointy end represents 1 carbon. So in total we have six carbons.
The name of this organic compound is hexane.
Answer:
The Coriolis effect is caused by the rotation of the earth around its own axis.
Explanation:
The Coriolis effect arises from the fact that different latitudes of the earth's surface rotate at different speeds. The path of wind on earth is deflected by the Coriolis effect. As things move over the earth, they meet different speed areas, which causes the Coriolis Effect to divert their route.
Thus, The Coriolis effect is caused by the rotation of the earth around its own axis.
Mass of copper : 0.165 g
<h3>Further explanation</h3>
Given
5.0 A over 100 seconds
Required
Mass of copper
Solution
Faraday's law:
<em>The mass of the substance formed at each electrode is proportional to the electric current flowing in the electrolysis</em>
<em />
<em />
e = Ar / valence = eqivalent weight
i = current
t = time
W = weight
CuSO₄ ----> Cu²⁺ + SO₄²⁻
Cu ----> Cu²⁺ + 2e
e = Ar/2
= 63,5/2 = 31,75
