Answer:
Value of is 0.090.
Explanation:
Initial molarity of =
= 0.0700 M
Construct an ICE table corresponding to the combustion reaction of carbon to determine
I (M): - 0.0700 0
C (M): - -x +2x
E (M): - 0.0700-x 2x
So, , where [CO] and
represents equilibrium concentration of CO and
respectively.
Here,
⇒x = 0.030
So, = 0.0700-x = (0.0700-0.030) = 0.040
Hence,
Answer:
122.5 Joule, or 122.5 j
Explanation:
Given,
mass of the object (m) = 5 kg
velocity of the object (v) = 7 m/s
Kinetic energy = × m × v²
Applying the formula:
Kinetic energy = × 5 × 7²
⇒ × 5 × 7 × 7
⇒
⇒ 122.5 Joule, or 122.5 j
Kinetic energy is the energy that an object gains as the result of the motion. It also depends on the mass of the object and force with which the motion is applied. In the given question, the mass of the object is 5 kg and the force of the velocity by which it is moving is 7 m/s.

Explanation:
In a chemical reaction, a particular reaction path may be favoured due to the fact that it is energetically more favourable(lower energy sigma complex is formed).
The more the resonance structures produced in a particular reaction pathway, the more energetically favourable it is.
In the chlorination of bromobenzene, ortho attack and para attack are preferred because each of these pathways involves a sigma complex with__4________resonance structures. Attack at the meta position involves formation of a sigma complex with only____3_______ resonance structures. The reaction will proceed more rapidly via the_____lower_______ energy sigma complex, so attack takes place at the ortho and para positions in preference to the meta position.
