Answer:
C) Potassium, K, and calcium, Ca
Explanation:
Given pair of elements:
Ni and Cu
Potassium and Ca
Nitrogen and oxygen
Solution:
We know that number of protons and number of electrons are always equal and number of electron or number of proton is called atomic number.
Number of protons given elements:
Ni number of protons = 28
Copper number of protons = 29
Combine number of protons = 57
K number of protons = 19
Ca number of protons = 20
Combine number of protons = 39
Ni number of protons = 7
O number of protons = 8
Combine number of protons = 15
Thus, option C is correct.
Assuming ideality:
PV=nRT
Pv= (mass/molarmass)RT
Solve for the mass :-)
Answer: Water H2O
Explanation:
In cellular respiration process NAD+ is a most versatile electron acceptor and functions in several of the redox steps during break down of glucose.
Each NADH molecules formed during respiration represents stored energy that can be tapped to make ATP when the electrons complete their ''fall''down an energy gradient from NADH to oxygen.
Electrons removed from glucose are shuttle by NADH to the ''top'', higher-energy end of the electron transport chain. At the ''bottom'' lower energy end, O2 captures these electrons along with H+ forming water.
Therefore Hydrogen removed from NADH in the ETC is captured by O2 to form water
2H + 1/2O2 ------> H20
Solvation is the process of dissolving.
Dissociation is the separation of a substance into charged components during dissolution.
<h3>What is the difference between dissolving and dissociating?</h3>
Dissolution (dissolving), which simply refers to becoming solvated by the solvent, is a subset of dissociation, which is particularly the separation of two charged ions in solution. When the solvent completely envelops each individual solute molecule, solvation takes place. By definition, something that is dissociated in a solvent must be dissolved in it. For instance, the salt dissociates in water, which is how it dissolves in water. In water, ethanol dissolves but does not dissociate; it remains ethanol.
<h3>How does Van't Hoff's factor work?</h3>
The Van't Hoff factor is a tool used to compare the real number of moles of solute injected to create a solution to the apparent amount produced by colloidal characteristics.
<h3>What is the Van't Hoff factor's value?</h3>
Van't Hoff factor's value is:-
- No association or dissociation i=1
- Dissociation i<1
- Association i>1
