Answer:
A is oxidation . B is reduction
Explanation:
A will be oxidation agent because there is gain of
electrons
B will be reducing agent because there is loss of
electrons.
C or D! When reduced coenzymes produce in the process of the cycle, are oxidized in the process of oxidative phosphorylation in electron transport chain! I hope this helps :(
Answer:
177.3kg C₂₁H₄₄
Explanation:
Based on the chemical reaction:
C₂₁H₄₄ → 3C₂H₄ + C₁₅H₃₂
<em>Where 1 mole of C₂₁H₄₄ produce 3 moles of ethene, C₂H₄.</em>
<em />
To solve this question we need to determine the moles of ethene in 50.4kg. 1/3 these moles are the moles of C₂₁H₄₄ that must be added:
<em>Moles Ethene -Molar mass: 28.05g/mol-</em>
50.4kg = 50400g * (1mol / 28.05g) = 1796.8 moles of ethene
<em>Moles C₂₁H₄₄:</em>
1796.8 moles of ethene * (1 mol C₂₁H₄₄ / 3 mol C₂H₄) = 589.93 moles C₂₁H₄₄
<em>Mass C₂₁H₄₄:</em>
589.93 moles C₂₁H₄₄ * (296g / mol) = 177283g =
<h3>177.3kg C₂₁H₄₄</h3>
Answer:
²⁵₁₁Na⁺
Explanation:
Details about the atom:
Number of electrons = 10 electrons
Number of neutrons = 14 neutrons
Number of protons = 11 protons
The atomic number of an atom is a good indicator of the type of atom we have been given.
From the subatomic particles, the number of protons is the same as the atomic number.
Since the number of protons is 11, its atomic number will be 11.
The element with atomic number 11 is sodium, Na.
To write a complete notation, we also need the mass number;
Mass number = number of protons + number of neutrons
Mass number = 11 + 14 = 25
The charge on the atom:
Charge = Number of protons - number of electrons = 11 - 10 = 1+
The element in isotopic notation is given as;
²⁵₁₁Na⁺
Pure water does
not have enough ions to conduct electricity. A mixture of metals such as iron,
zinc and copper in the wet soil can trigger electrolysis that requires excess
energy in the form of over potential to conduct electricity. The excess energy
is needed due to limited self-ionization of water. The wet soil then can
conduct current when positive and negative ions are present. The water ions begin
to flow from anode (positive electrode) to cathode (negative electrode) to be oxidize
and produce electricity.
