Answer:
163.44 g
Explanation:
We know that one ton is equal to 2000 lbs and one lb is equal to 454 grams.
Solution:
1.80 × 10∧-4 ton× 2000 lb/ton× 454 g/lb
1.80 × 10∧-4 ton× 2× 10³lb/ton× 454 g/lb
1634.4 g/ 10 = 163.44 g
Answer:
a) a space in an atom where an electron is most likely to be found
Explanation:
Atomic orbital is the mathematical function which describes wave-like behavior of the electrons present in the atom.
It is used to calculate probability of finding the electron of the atom in any region around nucleus of the atom. Atomic orbital is the physical region or a three dimensional space where the probability of finding the electron is more than 90% which also means that the space where an electron is most likely to be found. They are boundless space and have definite energy.
Option A best describes atomic orbital.
Answer:
When the Zebra arrived they ate all the food so the Unionid mussels declined as they died from the lack of food. Causing the Zebra Zebra numbers to increase and Unionid numbers to decline.
Answer:
4.13 moles of Fe.
Explanation:
Given data:
Moles of iron produced = ?
Moles of Fe₂O₃ = 3.5 mol
Moles of CO = 6.2 mol
Solution:
Chemical equation:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Now we will compare the moles of iron with CO and Fe₂O₃.
Fe₂O₃ : Fe
1 : 2
3.5 : 2/1×3.5 = 7 mol
CO : Fe
3 : 2
6.2 : 2/3×6.2 = 4.13 mol
The number of moles of iron produced by CO are less it will limiting reactant.
Thus, moles of iron formed in given reaction are 4.13 moles.
Answer:
6
Explanation:
2A is a molecule Argon bond. so, it's 1 + 2+ 3
