Atomic Mass Number = Atomic Number + Number of Neutrons
Explanation:
i guess it's through thousands of research and experiments they conducted
Answer:
The answer should be 2 because to balance the equation you should have to change to equation to this; 2Al + 3Br2 => 2AlBr3, so that there is a total of 2 Aluminums and 6 Bromiums on either side of the equation.
Explanation:
Answer: The force of gravity decreases.
Explanation: There are a lot of explanations for it. Look at Einstein's Theory of General Relativity & Newton's law of universal gravitation.
Answer:
(A) stoichiometry
Explanation:
For example, Consider the reaction of the type ,
aA + bB-----> cC +dD
where b, a, d, and c are the stoichiometric coefficients for the balanced equation .
The equilibrium constant expression is denoted by K ,
equilibrium constant is the product's concentration each raised to the power of its corresponding stoichiometries , divided by reactant's concentration each raised to the power of its corresponding stoichiometries .
