The equation is unbalanced because the number of hydrogen atoms and sodium atoms is not equal in the reactants and the products
Answer:
explained
Explanation:
Electrons use light energy to move among energy levels within an atom because of the following reason
Electrons in each orbit around an atom have some specific energy. However, they can emit or absorb photons of the energy equal to difference of the energy between these specific energy levels within an atom. If the electron absorbs an photon, it can move up the energy level, if the electron emits a photon, it can move down to a energy level.

I just want the points but you should pay attention in class jk
Answer:
Explanation:
Component of force perpendicular to stick
= F Sin 60°
=√3 / 2 F.
Taking torque about the other end
= √3 / 2 F x 1 Nm
Weight of stick = 60 gm
= 60 x 10⁻³ kg
= 60 x 10⁻³ x 9.8 N
= .588 N
This weight will act from the middle point of stick so torque about the
other end
= .588 x 1 Nm
Balancing these two torques we have
.588 = √3 /2 F
F = 0.679 N
