Double-replacement
An exothermic chemical reaction.
associative property
x2+bx+ax+ab = x2+ax+bx+ab = x(x+a)+b(x+a) = (x+a)(x+b)
30 + ab + 6b + 5a = 5(a+6) + b(a+6) = (b+5)(a+6)
ab-2ac+b^2-2bc
I suppose that you think to synthesis reaction.
This kind of chemical reaction is usually called "displacement" and sometimes "substitution".
Double replacement
AB pos or AB neg
The symbol "ab" typically represents a combination of two elements or compounds, indicating a reaction where they react to form a new product, often in the context of a chemical reaction. It can denote the reaction between reactants "a" and "b," resulting in a product or products. This representation is often used in various scientific fields, including chemistry and physics, to illustrate the relationship between reactants and products.
An exothermic chemical reaction.
needing sum helo here
When many were taught chemistry in the 1970s this was called a double decomposition reaction. It is now called a salt metathesis reaction and also double displacement reaction. There are examples and more information at the related link.
This equation represents an elementary example of a synthesis type reaction. The formula for this reaction is A + B = AB, where A & B are reactants and AB is the product.
yes because ab plus bc is ac
Commutativity.
No - a pos can not donate blood to a negative
