Answer:
Aluminum oxide has a chemical formula ai2o3, it is used in various chemicals.
Explanation:
Molarity HNO3 = 0.85 M
Volume HNO3 = 38.5 mL in liters: 38.5 / 1000 => 0.0385 L
Molarity Ba(OH)2 = ?
Volume Ba(OH)2 = 20.0 mL / 1000 => 0.02 L
Number of moles HNO3 :
n = M x V
n = 0.85 x 0.0385<span> => 0.032725 moles
mole ratio :
</span><span>Ba(OH)2 + 2 HNO3 = Ba(NO3)2 + 2 H2O
</span>
1 mole Ba(OH)2 ----------- 2 moles HNO3
( moles Ba(OH)2 ) -------- 0.032725 HNO3
moles Ba(OH)2 = 0.032725 x 1 / 2
moles Ba(OH)2 = 0.032725 / 2
= 0.0163625 moles of Ba(OH)2
Molarity Ba(OH)2 :
M = n / V
M =0.0163<span>625</span> / <span>0.02
= 0.82 M

Answer:
Ocean currents!!
Explanation:
The Oceans of the earth transfer heat from one location to another via massive ocean currents. These currents are like river flowing across the vastness of Earth, bringing warm water from the equator up towards higher latitudes, and cooler water down towards the equator.
