Answer:
33 degress celcuis would be the answer because you have to divide all the numbers
Explanation:
Answer:
Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock. Movement is caused by shear stress sufficient to produce permanent deformation, but too small to produce shear failure. ... Continuous, where shear stress continuously exceeds the strength of the material.
Explanation:
Explanation:
At sea level, the atmospheric pressure would be a little over 100 kPa (one atmosphere or 760 mm Hg). If we climb to the top of Mount Everest (the highest mountain in the world at 29,029 feet or 8848 meters), the atmospheric pressure will drop to slightly over 30 kPa (about 0.30 atmospheres or 228 mm Hg).

Answer:
Ruthenium has an oxidation state of +2
Explanation:
Step 1: Data given
A current = 0.44 A
Time = 25.0 minutes
Mass of Ru(s) = 0.345 grams
Step 2: Calculate charge
Charge = current * time
Charge = 0.44 A * 25 min *60 sec/min
Charge = 660 C
Step 3: Calculate moles electrons
1 mol e- = 660 C * (1 mol e-/ 96500 C)
1 mol e- = 6.84 * 10^-3 mol e-
Step 4: Calculate moles of Ru
Moles Ru = mass Ru / molar mass Ru
Moles Ru = 0.345 grams / 101 g/mol
Moles Ru = 3.416 * 10^-3 moles Ru
Step 5: Calculate oxidation state of ruthenium
(6.84e-3 moles e-) / (3.416e-3 moles Ru) = 2 e- / Ru atom (Ru+2)
Ruthenium has an oxidation state of +2
Since a nitrate ion has a charge of -1, ruthenium nitrate would be
Ru(NO3)2
