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).
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 kind of chemical reaction is usually called "displacement" and sometimes "substitution".
= (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
