Answer:
83.000
Step-by-step explanation:
8.3 × 10⁴
= 8.3 × (10 × 10 × 10 × 10)
= 8.3 × (100 × 10 × 10)
= 8.3 × (100 × 100)
= 8.3 × 10.000
= 83.000
Conclusion:
The result of 8.3 × 10⁴ is 83.000
Answer:
a) 40 %
b)
c)
Explanation:
For a) we will have to calculate the <u>molar mass</u> of , so the first step is to find the <u>atomic mass</u> of each atom and multiply by the <u>amount of atoms</u> in the molecule.
C => 12*(6) = 72
H => 1*(12) = 12
O => 6*(16) = 96
Molar mass = 180 g/mol
Then we can calculate the percentage by mass:
For b) we have to start with the <u>reaction of glucose</u>:
Then we have to convert the grams of glucose to moles, the moles of glucose to moles of carbon dioxide and finally the moles of carbon dioxide to grams. To do this we have to take into account the<u> following conversion ratios</u>:
-) 180 g of glucose = 1 mol glucose
-) 1 mol glucose = 6 mol carbon dioxide
-) 1 mol carbon dioxide = 44 g carbon dioxide
For C, we have to start with the conversion from grams of glucose to moles, the moles of glucose to moles of oxygen and finally the moles of oxygen to molecules. To do this we have to take into account the <u>following conversion ratios</u>:
-) 180 g of glucose = 1 mol glucose
-) 1 mol glucose = 6 mol oxygen
-) 1 mol oxygen = 6.023x10^23 molecules of O2
M=pV p(density) v(volume)
V=nRT/P
A gene or trait that appears or expresses itself over a recessive trait is called
C. a dominant gene.
Hope this answers your question!
Given that,
The equation is :
To find,
The missing coefficients.
Solution,
Let the value of ? is x.
It is the equation of photosynthesis.
In LHS,
Carbon atoms = 6
Hydrogen atom = 12
Oxygen atom = 18
In RHS,
Carbon atoms = 6
Hydrogen atom = 12
Oxygen atom = 6
If we make the equation as
No the number of atoms in RHS = 6+ 12 = 18
It means if we take the value of ? as 6 the equation will be balanced.
Hence, the correct option is (B) "6".
