Answer:
by equal number of protons and electrons it balances it out
Subduction occurs when two plates collide at a convergent boundary, and one plate is driven beneath the other, back into the Earth’s interior. Not all convergence leads to subduction. Continental rocks are too buoyant to be forced downward, so when continents collide, they crumple but stay at the surface. Only oceanic plates, which are topped with basalt, are dense enough to sink into the mantle. As a result, only oceanic plates are subducted.
Answer:
False
Explanation:
if this were true then water would not be available on earth other than in the atmosphere because of evaporation
Answer:
2.35 x 10²³atoms
Explanation:
Given parameters:
Number of moles of Be = 0.39moles
Unknown:
Number of atoms = ?
Solution:
To solve this problem:
1 mole of a substance contains 6.02 x 10²³ atoms
0.39 mole of Be will contain 0.39 x 6.02 x 10²³ = 2.35 x 10²³atoms
Answer:
Urinary system here is best described as:
D. regulates fluid balance and eliminates waste.
Explanation:
- The major functional organ i.e.our kidney is responsible and is the major functional organ that carry out the urine out of the body.
