<span>Energy is absorbed and then released to form an emission line.
When electrons absorb energy they increase there energy level. This is only temporary and the excited electron then relaxes back down to its original energy level releasing energy.
The energy is released in form of EM radiation of a specific frequency depending on the element and how many energy levels the electron relaxes.
This forms an emission line.</span><span />
Q = mCΔT
Q is heat in joules, m is mass, C is specific heat, and delta T is change in temp
2099 J = (40.27g)(C)(148.5 - 24.8) = .421 J / gram K
Answer:
The new pressure is 8.58 atm
Explanation:
Using Boyle's law which states that the pressure of a gas is inversely proportional to the volume of the gas and mathematically written as;
P1 V1 = P2 V2
P1 = 3.7atm
V1 = 5.8L
V2 = 2.5L
P2 = ?
Equate the values to the equation and solve for P2:
P2 = P1 V1 / V2
P2 = 3.7 * 5.8 / 2.5
P2 = 21.46 / 2.5
P2 = 8.584 atm
The new pressure acting on the balloon is therefore 8.58atm
I believe the correct answer would be letter C: removing an inhibitor. First of all, a catalyst increases the rate of reactions. Also, increasing temperature causes more reaction because molecules are more active this way. Lastly, lowering the concentration of the reactants will not increase the rate of reactions because again, high concentration causes collision..
