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.
1) 180 days. 24 hours in a day. 60 minutes in an hour. 24X60=1440. Then, take that by the days: 180. 180X1440=259,200 minutes in 180 days.
2) One English ton is 2,240 pounds. There are approximately 453.6 grams in one pound. 1.8X10^-4= .00018(2240)=.4032 TONS. To convert to pounds: .4032(2240)=903.168. To convert that to grams, multiply by the number of grams in a pound. 453.6(903.168)=409,677 grams. I apologize if I misunderstood your question (your 1.80X10-4 Tons was confusing)
3)First of all, figure out how many years 62 months is. The closest divisible is 60, which would be 5 years. So, first let's take care of the 5 years. Multiply it by the number of minutes in a year to start. 525,600(5)=2,628,000 minutes. Then multiply by 60 to get seconds: 2,628,000(60)= 157,680,000. Now, DON'T FORGET the other two months! Assuming that they are normal months (not February), they would equal 61 days (one 31 days, the other 30). The seconds in a day are 24x60x60=8,400. Multiply that by your number of days. 8,400(61)=5,270,400. DON'T FORGET TO ADD THEM TOGETHER!!! Add your two months and your 5 years: 157,680,000+5,270,400= 162,950,400 seconds!
Chemsits identify elements and compounds by using the Periodic Table. All elements have Atomic Numbers, Chemical Names, Atomic Mass, Period, and are usually colored and put into their group.
Answer:
Compounds because they all have chemical formulas
Explanation:
In the question, you can see their formulas (CO2, H2O and C6H12O6)
This means they are compounds and are chemically bonded together, so cannot be mixtures. They cannot be elements either because each compound is made up of multiple elements.
Hope this helps! Let me know if you have any questions :)
