Commutativity.
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
ab + 2
ab=1a+1b a is equal to either 0 or two, and b is equal to a
The existence of the additive inverse (of ab).
The reaction between hydrogen and iodine to form hydrogen iodide is a synthesis reaction, also known as a combination reaction. In this type of reaction, two or more reactants combine to form a single product.
I suppose that you think to synthesis reaction.
An exothermic chemical reaction.
Double-replacement
An acid plus a base will yield a salt and water. In textbooks this is often written as: HA + BOH yields AB + HOH The above means an acid with its hydronium ion added to a base with its hydroxyl group will yield a salt composed of the acid and the base plus water (hydrogen plus hydroxyl is HOH or H2O).
This kind of chemical reaction is usually called "displacement" and sometimes "substitution".
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.
= (a + b)2 or (a + b)(a + b) (a + b)(a + b) using the FOIL method yields: [multiplying {First Outer Inner Last} and summing the products] = a.a + a.b + b.a + b.b = a2 + ab + ab + b2 = a2 + 2ab + b2
The chemical reaction consists of reactants A and B reacting to form product AB. A and B are the reactants, while AB is the product.
yes because ab plus bc is ac
No - a pos can not donate blood to a negative
