In terms of electrons why does a cation have a positive charge

1 answer:

5 0

Because a CATION is a name for a POSITIVE ION and it is given that name if an atom loses an electron.

Also the roman numerals after a transition metals name tell u its charge E. G. Iron(II) will have the charge Fe2+

Rate law equation The rate of a chemical reaction depends on the concentrations of the reactants. For the general reaction betwe

Answer: The reaction order with respect to A is m

Explanation:

Order of the reaction is defined as the sum of the concentration of terms on which the rate of the reaction actually depends. It is the sum of the exponents of the molar concentration in the rate law expression.

Elementary reactions are defined as the reactions for which the order of the reaction is same as its molecularity and order with respect to each reactant is equal to its stoichiometric coefficient as represented in the balanced chemical reaction.

For the given reaction:

$aA+bB\rightleftharpoons cC+dD$

$Rate=k[A]^m[B]^n$

In this equation, the order with respect to each reactant is not equal to its stoichiometric coefficient which is represented in the balanced chemical reaction.

Hence, this is not considered as an elementary reaction.

Order with respect to A = m

Order with respect to B = n

Overall order = m+n

Thus order with respect to A is m.

Develop a demonstration to show how mass is not the same thing as weight

pychu [463]

This is more of a physics explanation, but here we go.

Mass is a measure of how much "matter" is in an object. Weight is the force applied onto an object by gravity. Weight itself can be related to mass like this:

$f_g = mg$

where g is a gravitational constant. For our purposes, it's defined by whatever planet you are on. Following this, we can demonstrate that mass is NOT the same thing as weight if we take two objects of the same mass and put them on different planets.

Let E refer to Earth and F refer to Mars

$g_E = 9.81 m/s^2\\g_F = 3.711 m/s^2$

Following this, we can see clearly that weight is not the same as mass:

$m*9.81 : m*3.711 \\\int\limits^a_b {x} \, dx 9.81 \neq 3.711\\f_g E \neq f_g F\\$

If weight was the same thing as mass, the two values would be the same, as the mass of the two objects is the same. But since weight is defined in the context of gravity, they are not.
