Answer:
Gravity
because the earth which pulls any object towards it center and the velocity is achieved
Answer:
The answer to your question is <u>111 g of CaCl₂</u>
Explanation:
Reaction
2HCl + CaCO₃ ⇒ CaCl₂ + CO₂ + H₂O
Process
1.- Calculate the molecular mass of Calcium carbonate and calcium chloride
CaCO₃ = (1 x 40) + (1 x 12) + ((16 x 3) = 100 g
CaCl₂ = (1 x 40) + (35.5 x 2) = 111 g
2.- Calculate the amount of calcium chloride produced using proportions.
The proportion CaCO₃ to CaCl₂ is 1 : 1.
100 g of CaCO₃ ------------- 111 g of CaCl₂
Then 111g of CaCl₂ will be produced.
Im pretty sure its the sun.
Hope you have a grrreat day!
When the Earth's surface absorbs the sun's energy, it turns the light into heat. This heat on Earth's surface warms the air above it. The air over the Equator gets warmer than the surface air near the poles. This moving air is what we call wind.
Mark brainless if possible :) Have a good day !
