2) 330000000
Explanation:
1) 3.7 x 10^7 = 37100000
2) 3.30 x 10^8 = 330000000
(Hope this helps can I pls have brainlist (crown)☺️)
The answer is As2O5
good luck
Answer: as the temperature increases, the kinetic energy of the molecules increases
Explanation: The kinetic energy of the molecules is the energy possessed by virtue of motion of the particles.
Kinetic energy of the particles is directly proportional to the temperature of the gas.

where T= temperature
R= gas constant
Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.
Answer:
ΔE = 5.02 x 10⁻¹⁹ j
Explanation:
ΔE (photon) = h·f = (6.63 x 10⁻³⁴ j·s)(7.57 x 10¹⁴ s⁻¹) = 5.02 x 10⁻¹⁹ j
h = Planck's Constant = 6.63 x 10⁻³⁴ j·s
f = frequency (given) = 7.57 x 10¹⁴ s⁻¹
