Answer:
4.13 moles of Fe
Explanation:
Step 1: Write the balanced equation
3 CO + Fe₂O₃ ⇒ 2 Fe + 3 CO₂
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of CO to Fe is 3:2.
Step 3: Calculate the moles of Fe formed from 6.20 moles of CO
We will use the previously established molar ratio.
6.20 mol CO × 2 mol Fe/3 mol CO = 4.13 mol Fe
Answer:
a) 
and 
b) 
and 
c) 
and 
Explanation:
Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like 
, 
and 
These units of temperature are inter convertible.
a) 68°F (a pleasant spring day) to °C and K.
Converting this unit of temperature into and by using conversion factor:
b) 164°C (the boiling point of methane, the main component of natural gas) to K and °F
Conversion from degree Celsius to Kelvins and Fahrenheit
c) 0K (absolute zero, theoretically the coldest possible temperature) to °C and °F.
Answer:
c2h4o2
Explanation:
I am using my cell. This could take a bit
The Empical formula has a mass of
C 12
2H 2
O 16
total = 30
The molecular mass is given as 60 which is 2 times the empirical mass. Therefore multiply each element by 2 in the empirical formula.
You get C2H4O2
If you would’ve attached a picture I’m sure it would’ve been a lot easier.
