Local winds blow over certain parts of the Earth, but global winds blow around the globe as the name 'global' suggests.
Local winds like the Sirocco, Harmattan, leveche, Nor'westers, Mistral, Chinook, Foehn can be found only in certain regions. For example, Sirocco, Harmattan, are seasonal winds blowing across Northern Africa and the Leveche blows over Southern Spain. The Chinook are warm winds flowing down the leeward side of the Rocky Mountains. The Mistral is a chilly wind which blow in the Mediterranean regions during winter.
The Trade winds, Mid Latitude Westerlies and Polar Easterlies are examples of global winds.
The Trade Winds are found between the 30 degrees S and N latitudes. There are the North-East Trades and the South-East Trades, both converging at the the Equator.
The Westerlies are a deep wind system found in the Temperate latitudes blowing from the West towards the East.
The Polar Easterlies blow from the Polar regions towards the Mid-latitudes.
Answer:
Copper ions are reduced into copper atoms.
Cu²⁺₍aq₎ + 2e⁻ → Cu₍s₎
Explanation:
During electrolysis, the positive H⁺ and Cu⁺ ions move to the negative cathode and negative OH⁻ and Cl⁻ ions move to the positive anode.
At cathode, copper ions are preferentially discharged due to the low electromotive force required to discharge them compared to the hydrogen ion. The copper ions gain the two electrons lost by the chloride ions when the are discharged. (2 Cl⁻₍aq₎ → Cl₂₍g₎ + 2e⁻)
Thus the half equation is as follows:
Cu²⁺₍aq₎ + 2e⁻ → Cu₍s₎
Answer:
The answer to your question is 16 g
Explanation:
Data
Percent by mass = 8%
Mass of the solution = 200 g
Mass of solute = ?
Formula
Percent by mass = mass of solute / mass of solution x 100
- Solve for mass of solute
Mass of solute = Percent by mass x mass of solution / 100
- Substitution
Mass of solute = 8 x 200 / 100
- Simplification
Mass of solute = 1600 / 100
- Result
Mass of solute = 16 g
Hz is the measurement of a frequency equal to one cycle per second. since this wave shows 9 peaks and valleys or "cycles" your answer would be 3 Hz due to the fact that the length of time is 3 seconds. (3 cycles per second X 3 seconds.)
C. Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent
B.The temperature of the solvent is another factor that affects how fast a solute dissolves. Generally, a solute dissolves faster in a warmer solvent than it does in a cooler solvent because particles have more energy of movement.
A. solute in solid state), temperature and amount of stirring.
