I don’t know so ask someone else
The balanced equation is C6H14(g)
+ 19/2O2(g) → 6CO2(g) + 7H2O(g). If you are given 7.9 moles C6H14, multiply it
by a ratio of 19/2/1 to get the moles of oxygen. Then, you will get 75.05 moles
of O2.
Answer:
Density of the object is 8759.494 grams/L
Explanation:
As we know density of an object is mass of the object divided by its volume
Given
Volume of the object is equal to the change in volume of water with in the cylinder when the object was immersed in water.
Hence, volume of object is equal to
mL
Mass of the object is grams
Density
grams/L
Density of the object is 8759.494 grams/L
It will have 98 number of electrons because the number of protons are equals to the number of electrons unless element x has isomers. if it has isomers then only it will have a different electron number but mind it the proton number will remain the same. note: if the proton number changes the whole element changes.
Answer:
1.35×10¹² μg
Explanation:
Mass (Kg) = 1350 Kg
Mass (μg) =?
Thus, we can obtain the mass of the adult rhino in micrograms (μg) by converting 1350 Kg to microgram (μg) as follow:
1 Kg = 1×10⁹ μg
Therefore,
1350 Kg = 1350 kg / 1 kg × 1×10⁹ μg
1350 Kg = 1.35×10¹² μg
Therefore, 1350 Kg is equivalent to 1.35×10¹² μg.
