Answer: We live at the bottom of a gaseous envelope the atmosphere--that is bound gravity to the planet Earth. The circulation of our atmosphere is a complex process because of the Earth's rotation and the tilt of its axis. The Earth's axis is inclined 23.5° from the ecliptic, the plane of the Earth's orbit around the Sun. Due to this inclination, vertical rays of the Sun strike 23.5° N. latitude, the Tropic of Cancer, at summer solstice in late June. At winter solstice, the vertical rays strike 23.5° S. Latitude, the Tropic of Capricorn. In the Northern Hemisphere, the summer solstice day has the most daylight hours, and the winter solstice has the fewest daylight hours each year. The tilt of the axis allows differential heating of the Earth's surface, which causes seasonal changes in the global circulation. On a planetary scale, the circulation of air between the hot Equator and the cold North and South Poles creates pressure belts that influence weather. Air warmed by the Sun rises at the Equator, cools as it moves toward the poles, descends as cold air over the poles, and warms again as it moves over the surface of the Earth toward the Equator. This simple pattern of atmospheric convection.
Answer:

Explanation:
I think hope this helps!! :D
N a polar covalent bond<span>, the electrons shared by the atoms spend a greater amount of time, on the average, closer to the Oxygen nucleus than the Hydrogen nucleus. This is because of the geometry of the molecule and the great electronegativity difference between the Hydrogen atom and the Oxygen atom.</span>
Answer:
4.55 mol of C₂H₂
Explanation:
Let's verify the reaction:
CaC₂ + 2H₂O → C₂H₂ + Ca(OH)₂
Ratio is 1:1, so 1 mol of calcium carbide will produce 1 mol of acetylene.
4.55 mol of CaC₂ will make the same amount of C₂H₂
Answer:
Zr. You should be able to see it on a periodic table.
