Answer:
C. 3.33 moles
Step-by-step explanation:
Ammonia decomposes
We have to find the moles of hydrogen formed in 2.22 moles of ammonia.
From the reaction
2 moles of ammonia gives 3 moles of hydrogen
1 mole of ammonia produce hydrogen=3/2 moles
2.22 moles of ammonia produces hydrogen= moles
Number of moles of hydrogen formed by decomposition of 2.22 moles of ammonia
=moles
Hence, 3.33 moles of hydrogen are formed in 2.22 moles of ammonia.
Option C is true.
C. 3.33 moles

Answer:
pos: 99. Sor: 17. roq: 64
Step-by-step explanation:
(5x+4)+(x-2)+(3x+7)=180
we add the angles to 180 because straight lines are equal to 180
5x+4+x-2+3x+7=180
5x+x+3x+4-2+7=180
9x+9=180
9x=
9x=171
x=19
then we plug x in
5(19)+4 + (19)-2 +3(19)+7 = 180
angles (left right)
99. 17. 64.
Answer:
Step-by-step explanation:
I'm guessing we need to find the GCF of the numbers on the numerator and the denominator.
The GCF of two numbers is the greatest common factor that fits into both numbers evenly, with no other factor bigger than it that can fit into both numbers.
1. 24/36
GCF(24, 36)=12
2. 12/18
GCF(12, 18) =6
3. 48/72
GCF (48, 72)=24
4. 30/54
GCF(30, 54)=6
5. 42/56
GCF(42, 56)=14
6. 38/57
GCF(38, 57)=19
7. 120/192
GCF(120, 192)=24
