What do the sub scripts in a chemical equation tell about the equation?
The subscript denotes how much of that atom is in the molecule.
What is the chemical equation of hydrgen?
The chemical symbol (not equation) of hydrogen is H; the diatomic molecule is H2.
How do you derive the isoelectric point equation from Henderson hasselbalch equation?
The isoelectric point (pI) is the pH at which a molecule has no net charge. To find pI from the Henderson-Hasselbalch equation, set the net charge of the molecule equal to zero and solve for pH. This equation is derived by considering the acidic and basic dissociation constants of the molecule to calculate the pH at which the net charge is zero.
Which equation best represents the dissociation of water molecule into hydrogen ions and hydroxide ions?
The equation is: H2O------>H+ + OH-
What is a number added to an atom or molecule to help balance a chemical equation?
A coefficient.
What is the balanced equation burning phosphorous in air?
If there is an excess of air, the reaction should produce diphosphorus pentoxide as its only product. If additionally the phosphorus molecule is simply a phosphorus atom, the balanced equation is: 4 P + 5 O2 -> 2P2O5. If phosphorus is considered to form a tetraatomic molecule, the equation would be: P4 + 5 O2 -> 2 P2O5
Balanced equation for the burning carbon in air?
The balanced equation for the burning of carbon in air is: C + O2 -> CO2. This equation shows that one molecule of carbon reacts with two molecules of oxygen to produce one molecule of carbon dioxide.
The molecule referred to as ''molecule A'' in the equation above is?
The one labelled "molecule A".
What are coeffients in a chemical equation?
The amount of each molecule
What do the sub scripts in a chemical equation tell about the equation?
The subscript denotes how much of that atom is in the molecule.
What is the chemical equation of hydrgen?
The chemical symbol (not equation) of hydrogen is H; the diatomic molecule is H2.
What coefficient does HCl have in the following balanced equation CaCl2 plus H2CO3CaCO3 plus HCl?
The coefficient of HCl in the balanced equation is 2. This is because the balanced equation shows that 1 molecule of CaCl2 reacts with 1 molecule of H2CO3 to form 1 molecule of CaCO3 and 2 molecules of HCl.
What is the chemical equation for silicon atom and chlorine molecule?
The chemical equation for the reaction between a silicon atom and a chlorine molecule is: Si + Cl2 → SiCl4
How do you derive the isoelectric point equation from Henderson hasselbalch equation?

Is 6co2 carbion dioxide?
CO2 is carbon dioxide. You may have got this from a balanced equation. The 6, called a coefficient, in front of the molecule shows how many of the molecule is needed for it to balance out with the rest of the equation.
What is a substance or molecule that forms in a chemical equations?
A substance or molecule that forms in a chemical equation is a product. Products are the result of a chemical reaction between reactants, and they are found on the right side of a chemical equation.
Which molecule does the cell need in chemical equation of respiration?
The cell needs oxygen molecule (O2) in the chemical equation of respiration as it acts as the final electron acceptor in the electron transport chain to produce ATP.
