According to the octet rule, an atom with two electron shells is most stable when it contains eight electrons. The answer is letter B. All atoms wanted to attain a stable energy level equal to that of the noble gases. A noble gas is where all valence electrons in the valence shell is completely filled.

In the reaction _S+302 +2SO3, what coefficient should be placed in front of the S to balance the reaction?

lys-0071 [83]

Answer:

B. 2

Explanation:

The reaction expression is given as:

_S + 3O₂ → 2SO₃

Now let us balanced the expression;

On the product side we have 2 moles of S

On the reactant side we should have 2moles of S

So, we put the coefficient 2 to balance the expression;

We have 6 moles oxygen on both sides

the distance between any two bodies is 10 M and the gravitational force between them is 3.2×10-⁹m. if the mass of one object is

cluponka [151]

Answer:

0.8 x 10^-9 kg

Explanation:

Given,

Distance ( R ) = 10 m

Force ( F ) = 3.2 x 10^-9 N

Mass ( m1 ) = 40 kg

To find : Mass ( m2 ) = ?

Formula : -

F = m1.m2 / R^2

m2 = FR^2 / m1

= 3.2 x 10^-9 x 10 / 40

= 3.2 x 10^-9 / 4

= ( 3.2 / 4 ) x 10^-9

m2 = 0.8 x 10^-9 kg

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 60.0 m/s , and it leav

nata0808 [166]

Answer:

F = -307.4 N

Explanation:

It is given that,

Mass of the baseball, m = 0.145 kg

Initial speed of the baseball, u = 60 m/s

Final speed of the baseball, $v=65\ cos(30)=56.29\ m/s$

Time of contact, $t=1.75\ ms=1.75\times 10^{-3}\ s$

(a) It is assumed to find the horizontal component of average force. It is given by :

$F=m\dfrac{v-u}{t}$

$F=0.145\dfrac{56.29-60}{1.75\times 10^{-3}}$

F = -307.4 N

So, the horizontal component of average force is 307.4 N. Hence, this is the required solution.
