Answer:
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
Explanation:
hope it's right
Answer:
rate = kxyz
Explanation:
It is worth knowing that the rate low can only be determined by experimentation only not by just balancing equations. So here we are told that all the reactants x , y and z are all first order. This is important because we use this as exponents. That is why the exponents of all the reactants will be 1.
rate = kxyz
Answer:
9.85% is the mass percent
Explanation:
Mass percent can be determined as mass of solute in 100 g of solution
The solution is soda
Sugar is the solute
(mass of solute / total mass of solution) . 100 =
(33 g / 335g) . 100 = 9.85%
