Answer:
Explanation:
Oxygen generally exists as a diatomic molecule in the atmosphere when it is not combined with any other element. It forms the molecule O2 because in that configuration, it has its lowest energy level when uncombined.
Answer:
3.11 L is the volume for the produced CO₂
Explanation:
The metabolic breakdown of glucose is the respiration reaction. It's a redox reaction type. The equation, as shown is:
C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O(l)
We assume that the oxygen is in excess, so the glucose is the limiting reagent. We define the moles:
3.68 g . 1mol / 180g = 0.0204 moles
Now we propose this rule of three:
1 mol of glucose produces 6 moles of CO₂
Therefore, 0.0204 moles of glucose may produce (0.0204 . 6 ) / 1 = 0.1224 moles of glucose. Now we apply the Ideal Gases Law, to find out the volume: P . V = n . R . T
V = (n . R . T) / P
37°C + 273 = 310K
V = (0.1224 mol . 0.082 L.atm/mol.K . 310K) / 1 atm = 3.11 L
Surface waves can occur along any boundary of two different substances. Hope that helped! :)
Answer : The speed in meters per second is 17.89 m/s
Explanation :
The conversion used from miles to feet is:
1 mile = 5280 ft
40 miles= 
The conversion used from feet to inches is:
1 ft = 12 in
211200ft = 
The conversion used from inch to cm is:
1 in = 2.54 cm
2534400in= 
The conversion used from cm to m:
100 cm = 1m
6437376 cm = 
The conversion used from hour to min is:
1 hr = 60 min
The conversion used from hour to min is:
1 min = 60 sec
60 min =
We are asked: 40 miles/hr = ? m/s
Therefore, the speed in meters per second is 17.89 m/s
Answer: If the atoms of an element always have the same charge, the Roman numeral is not needed. For example, all cations formed from sodium atoms have a +1 charge, so Na+ is named sodium ion, without the Roman numeral for the charge.
