Answer:
The mass of the nucleus is almost the same as the atom because a majority of the mass of an atom is stored in the nucleus.
The volume of an atom is larger than the nucleus. The nucleus is a tiny, concentrated area inside of the atom. Atoms are mostly empty space inside.
Explanation:
Answer:
No reaction
Explanation:
Single-displacement reaction is the chemical reaction in which one metal which has higher negative redox potential replaces the another from it's salt solution.
Thus, Cu cannot replaces zine from its salt as it is less reactive than zince.
However, zinc can replace copper from its salt as:
Answer:
Half life = 1 / k[Ao]
Explanation:
From:
1/ [A] = kt + 1/ [Ao]
Isolating t on its own, we have:
kt = 1 / [A] - 1 / [Ao]
t = 1 / [Ao] / k
Re-arranging we have:
t = 1 / k [Ao]
The t represents the t=half life of the second order reaction and the formula can be re-written as:
t1/2 = 1 / k [Ao]
This is so because second order reaction decreases at a much faster rate than zero and first order reactions and there slopes decreases to zero at a much faster rate.
Answer:
alkenes and alkynes are considered as unsaturated hydrocarbons because they are capable of reacting with hydrogen in the presence of a catalyst to form a saturated hydrocarbon (alkanes)
Explanation:
A saturated compound contains a chain of carbon atoms joined by single bonds, with hydrogen atoms attached to each carbon atom.
Propane for example, CH₃-CH₂-CH₃.
It is saturated because all the carbon atoms holds maximum number of hydrogen atoms.
Alkenes such as Propene (CH₂=CH-CH₃) and alkynes like Propyne,
(CH₃-C≡C-H) are unsaturated because the central carbon atoms contain less number of hydrogen atoms than they possibly could.
The molar ratio of O2 / CO2 is 13:8, O2/H2O is 13:10, C4H10 / CO2 is 1:4 and C4H10 / H2O is 1:5.
<h3><u>Explanation</u>:</h3>
The mole concept is the concept of how many moles of a reactant reacts with how many moles of the reagent to produce how many moles of product. It gives us the stoichiometric ratio of the reactants with the products.
In the reaction we can see that 2 moles of butane reacts with 13 moles of oxygen to produce 8 moles of carbon dioxide and 10 moles of water. So the molar ratio of O2 / CO2 is 13:8, O2/H2O is 13:10, C4H10 / CO2 is 1:4 and C4H10 / H2O is 1:5.
