The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
Half-Cell Example The electrochemical reaction of a Daniell cell may be written as two half-cells. The original equation is: 2H+(aq) + 2e-→ H2(g) The half-cells or half-reactions are: Zn → Zn2++ 2e−(for the reaction at the anode or Zn) Cu2++ 2e−→ Cu (for the reacti...
What is the starting substance in a chemical reaction? Explain this reaction. What is chemical equilibrium? How do you write a chemical equation with no reaction? How does a precipitate form in a chemical reaction? What is the definition of solution in chemistry?
The yellow/orange stuff you get is a copper (I) compound. Under the given conditions, apparently the copper wire is not oxidized to copper (II), but to a copper (I) compound. More likely it is a copper (I) compound, contaminated with some copper (II).I think that at the anode you...
In a redox reaction, the oxidation has nothing to do with oxygen. Why is it called 'oxidation' then? Consider the following ion: XF2-2. What is the oxidation number assigned to element 'X'? What happens in an oxidation half reaction?
So, the correct answer is A.Note:Genes are contained in chromosomes. These in the cell nucleus. A single chromosome contains hundreds to thousands of genes. Every normal human cell comprises 23 pairs of chromosomes that mean a total of 46 chromosomes. A trait is any gene...
In MATLAB, you can use the “linsolve” function to solve for the variables in the equation. Here is an example of how you can use the “linsolve” function in MATLAB: The above code creates two matrices, A and B, and then solves for X in the equation AX = B. The result is X ...
What is ther coefficient for H^(+) when the half equation is balanced with the smallest whole number coefficients?
An example of a reaction is that between hydrogen and fluorine gas to formhydrofluoric acid: H2+ F2→ 2 HF In this reaction, hydrogen is being oxidized and fluorine is being reduced. The reaction may be better understood if it is written in terms of two half-reactions. ...
The most natural form of a neutralization reaction looks like the equation for pure water, which is: Acid + Base → Water + Salt Keep in mind that in chemistry, salt doesn't simply refer to the stuff you sprinkle on your food. There, it simply refers to the compound that can be creat...
