Answer:
Explanation:
Hello!
In this case, since the relationship between energy and wavelength is defined via the speed of light and the Planck's constant as shown below:
Since c stands for the speed of light and h for the so-called Planck's constant, we can compute the wavelength as follows:
Best regards!
Answer: increases
Explanation:
Increase in the temperature of a reaction system will cause the molecules of the reactants to possess higher kinetic energy which they would use to travel more randomly in the system, colliding more frequently with other excited molecules and with the wall of the containing vessel.
Thus, if temperature is increased, the number of collision per second also increases.
Answer:
The Answer is gonna be C) high pressure and low temperature
Answer:
184.113 g/mol
Explanation: The atomic mass of Mg is 24.3 amu. The atomic mass of bromine is 79.9. Therefore, the formula weight of MgBr2 equals 24.3 amu + (2 × 79.9 amu), or 184.1 amu. Because a substance's molar mass has the same numerical value as its formula weight, the molar mass of MgBr2 equals 184.1 g/mol.
The answer is 18.02 g/mol
