which two quantities are used to predict gravitational force according to Newton's law of universal gravitation a. mass and spee
NISA [10]

Answer:

(b). Mass and distance.

Explanation:

The gravitational force between two objects is given by Newton's law of universal gravitation. The formula is as follows :

F=G\dfrac{m_1m_2}{r^2}

Here,

G is universal gravitational constant

r is the distance between two objects

It is very clear that the gravitational force is directly proportional to the product of masses and inversely proportional to the square of the distance between them.

Hence, the two quantities are used to predict gravitational force according to Newton's law of universal gravitation are mass and distance.

Sulfur dioxide gas reacts with oxygen gas for form sulfur trioxide gas. the equilibrium constant for the reaction at 6000c is 4.
Art [367]
When the balanced equation for this reaction is:

            2SO3 → 2SO2 + O2 so, by using ICE table:

initial    0.391              0          0.125m

change  -X               +2X           +X

Equ     (0.391-X)         2X           0.125+X

when Keq = concentration of products / concentration of reactants

so, by substitution

    4.34  = [2X]^2 * [0.125+X] / [0.391-X]^2  by solving for X

∴ X = 0.357 m 

∴ the concentration of SO2 = 2x = 2 * 0.357 

                                               = 0.714 m
