Each mole of a substance contains 6.02 x 10²³ particles
Atoms of Fe = 4.5 x 6.02 x 10²³
= 2.709 x 10²⁹ atoms
Answer:
16.791 grams
Explanation:
The density formula is:

Rearrange the formula for m, the mass. Multiply both sides of the equation by v.


The mass of the gold nugget can be found by multiplying the density and volume. The density is 19.3 grams per cubic centimeter and the volume is 0.87 cubic centimeters.

Substitute the values into the formula.


Multiply. Note that the cubic centimeters, or cm³ will cancel each other out.


The mass of the gold nugget is 16.791 grams.
Answer:
2150 mmHg ( 1 atm / 760 mmHg ) ( 101.325 kPa / 1 atm ) = 286.643 kPa
Therefore, the closest value from the choices is the second one which has the value of 287, this would be answer.

Answer:
+2
Explanation:
If a compound
existed, we would identify the oxidation state of sulfur using the following logic:
- oxygen is more electronegative than sulfur, so it's more electron-withdrawing and it should have a negative oxidation state producing a positive oxidation state for sulfur;
- oxygen typically has an oxidation state of -2;
- we may then apply the fact that SO is expected to be a molecule with a net charge of 0;
- if the net charge is 0 and the oxidation state of oxygen is -2, we may set the oxidation state of S to x;
- write the equation for the net charge of 0 by adding all individual charges of the two atoms:
; - hence, x = 2.
That said, in this hypothetical compound S would have an oxidation state of +2.
