Answer:
Options A and B are correct.
Sodium salts and Carbon based fuels satisfy the criteria.
Explanation:
Sodium salts and Carbon Based fuels produce bright yellow emissions that can mask other emission colors.
Magnesium Salts produce no emissions, although, Magnesium metal burns brightly white while Aluminium salts produce white emissions.
Hope this Helps!!!
Answer:
The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
Explanation:
Mole percentage of nitrogen gas = 25 mole%
Mole percentage of hydrogen gas = 75 mole%
Average molecular weight of the mixture:
Rate of flow of the stream = 3000 kg/h
Mass of stream in 1 hour = 3000 kg = 3,000,000 g
Moles of stream :
Moles of nitrogen gas in 352,941.17 moles of stream be x
x = 88,235.294 mol
Mass of 8,823,529.4 mole of nitrogen gas:
The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
<h3><u>Answer</u>;</h3>
C3H4O
<h3><u>Explanation;</u></h3>
Empirical formula is the simplest formula of a compound;
Molar mass CO2 = 44.01
Mass of CO2 produced = 2.053 g
Mass of carbon in original sample = 12.01/44.01 × 2.053
= 0.5603g
Molar mass H2O = 18
Mass of H in original sample = 2/18 ×0.5601
= 0.0622 g
Thus; original sample contained 0.5603g C and 0.0622g H. The balance of the sample was O
Mass of O = 0.8715 - (0.5603 + 0.0622) = 0.249g
The mole ratio of C:H:O will be;
Moles C = 0.5603/12 = 0.0467
Moles H = 0.0622
Moles O = 0.249/16 = 0.01556
C:H:O = 0.0467:0.0622:0.01556
Divide through by 0.01556:
C:H:O = 3:4:1
Empirical formula is thus C3H4O
Answer:
That is alot to answer so i am not sure could answer this it is too hard maybe you could break it down for me cause this alot
Explanation:
- I wish i knew
- Its too much
- I don't know this kind of chemistry
- if you have another chemistry question i could answer plz let me know
- cause this too hard
