Answer: single replacement reaction
Explanation:
A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.
A general single displacement reaction can be represented as :
The reaction 
When zinc metal is added to aqueous silver nitrate, zinc being more reactive than silver displaces silver atom from its salt solution and lead to formation of zinc nitrate and silver metal.
Answer:
3 parts
Explanation:
Eukaryotic cells have 1) a membrane-bound nucleus; 2) numerous membrane-bound organelles and 3) several, rod-shaped chromosomes.
There are three major steps for finding an empirical formula from a combustion reaction.
1.) Determine the grams of carbon and hydrogen from the given data.
C: 23.98 g x (12.011 g / 44.01 g) = 6.54 g C
H: 4.91 g x (2.0158 g / 18.02 g) = 0.55 g H
Determine the grams of oxygen in the sample by subtracting the mass of the compound given from the total mass solved earlier.
O: 10.0 - (6.54 + 0.55) = 2.91 g O
2) Convert the values in step 1 to moles.
C: 6.54 g / 12.01 g / mol = 0.54 mol
H: 0.55 g / 1.01 g/mol = 0.54 mol
O: 2.91 g / 16.00 g/mol = 0.18 mol
3) Divide each by the lowest value calculated in step 2
C: 0.54 mol / 0.18 mol = 3
H: 0.54 mol / 0.18 mol = 3
O: 0.18 mol / 0.18 mol = 1
Thus, the empirical formula is C3H3O.
Answer : The atomic mass of carbon is, 12.01 amu
Explanation :
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
As we are given that,
- Mass of C-12 isotope = 12.00 amu
Percentage abundance of C-12 isotope = 98.93 %
Fractional abundance of C-12 isotope = 0.9893
- Mass of C-13 isotope = 13.00 amu
Percentage abundance of C-13 isotope = 1.07 %
Fractional abundance of C-13 isotope = 0.0107
Now put all the given values in above formula, we get:
![\text{Average atomic mass }=[(12.00\times 0.9893)+(13\times 0.0107)]](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20atomic%20mass%20%7D%3D%5B%2812.00%5Ctimes%200.9893%29%2B%2813%5Ctimes%200.0107%29%5D)
Therefore, the atomic mass of carbon is, 12.01 amu
