I don’t know but my guess is 80
Yes they do theyre always in a single phase
Answer:
Explanation:
As can be seen in the Figure in a face-centered cubic unit cell you have:
- Six halves of atoms
- Eight 1/8 of atom (1 in each corner)
In total:
Now, each side of the cell is 234 picometers (2.34e-8 cm) long
Atoms per cm3:
Expressing in mass:
Answer: 60.7 g of will be formed.
Explanation:
To calculate the moles :
The balanced chemical reaction is
is the limiting reagent as it limits the formation of product and is the excess reagent.
According to stoichiometry :
6 moles of produce = 4 moles of
Thus 2.68 moles of will produce= of
Mass of
Thus 60.7 g of will be formed by reactiong 60 L of hydrogen gas with an excess of
Answer: Number of Significant Figures: 3
The Significant Figures are 6 0 2
Explanation:
6.02 x10^5
Significant figures are the digits of a number that are meaningful in terms of accuracy or precision. They include:
Any non-zero digit
Zeros between non-zero digits as in 3003 or 45.60009
Trailing zeros only when there is a decimal point as in 6750. or 274.3300
