At the sea shore there is less water so the sun shines directly in them, deeper. there is more water. so their bodies are more in the water therefore the sun is less in their bodies.
2) a mixture of variables
Answer:
what are metals and non metals ?
define sulphur ?
Explanation:
0.074Hz is the answer to that
Answer:
0.257M HNO3
Explanation:
The reaction of HNO3 with Ba(OH)2 is:
2 HNO₃ + Ba(OH)₂ → 2 H₂O + Ba(NO₃)₂
That means 2 moles of HNO3 reacts with 1 mole of Ba(OH)2.
51,3mL of 0.250M Ba(OH)2 are:
0.0513L ₓ (0.250mol / L) = 0.0128moles
Moles of HNO3 are:
0.0128moles Ba(OH)2 ₓ (2 mol HNO3 / 1 mol Ba(OH)2) = 0.0257mol HNO3
As these moles are in 0.100L:
0.0257mol HNO3 / 0.100L = <em>0.257M HNO3</em>
