Answer:
Biosphere
Explanation:
because of the rain it gets from huge water sources.
I hope that was useful.
<span>C6H12 = 6x12 + 6x1 = 78.
The equation indicates that 2x78 = 156g benzene will produce 6542kJ.
Using proportions you can then calculate that
x/6542kJ = 7.9g / 156g
x = 331.3kJ = 331300J.
heat = mass x ΔT x 4.18J/g°
ΔT = 331300J / (5691g x 4.18J/g°) = 13.9°
final temp = 21 + 14° = 35°C</span>
Here we have to get the mass of the iron (Fe) produces in the reaction between ferric oxide (Fe₂O₃) and carbon monooxide (CO) to produce carbon dioxide and iron.
The amount of Fe produced in the reaction is B. 99.7g.
The balanced form of the reaction given is: Fe₂O₃ (s) + 3CO = 2Fe + 3CO₂.
Now as per the reaction 3 moles of CO produce 2 moles of Fe.
The molar mass of CO and Fe are 28.01g/mol and 55.845g/mol.
Thus (3×28.01) 84.03g of CO produces 111.69g of Fe.
Hence, 75.0g of CO produces 
×75.0 = 99.687g of Fe or 99.7g of Fe.
A. If in the reaction 49.8g Fe is produced in the reaction then 
×49.8 = 37.467g of CO should react. Thus the option is wrong.
C. To produce 224g of Fe ×224 = 168.526g of CO will consumed. Thus it is wrong statement.
D. To generate 299g of Fe ×299 = 224.952g of CO will consumed. Thus it is wrong statement.
Answer:
option D= Gold (I) nitride
Explanation:
The name of the given compound is gold(I) nitride.
Molar mass can be determine by following way:
molar mass Au3N = (molar mass of gold × 3) + (molar mass of nitrogen)
molar mass Au3N = (196.97 × 3 ) + ( 14 )
molar mass of Au3N = 590.91 g/mol + 14 g/mol
molar mass of Au3N = 604.91 g/mol
The nitrogen has valency of -3 so three Au(+1) will require while the valency of Au is (1+) one nitrogen will require to make the compound overall neutral.
Au3N
3(1+) + (-3) = 0
+3 - 3 = 0
0 = 0
The overall charge is 0, the compound will be neutral.
Answer:
the temperature difference between the water and the ice cubes causes heat to be transferred from the water to the ice cubes,.
Explanation:
Heat always travels to where it is colder. Think about how ice cubes melt. They are very cold so the heat is transferred to them from he warmer water and they melt.
hope this helps! i would really appreciate brainliest :)
