<span>The two categories for classifying particulate matter are through analysis of the intensive and extensive properties. Intensive properties are independent properties that can be measured independent of the amount of matter while extensive properties are measured dependent on the amount.</span>
Answer:
According to the collision theory, we can increase the rate of a reaction by increasing the concentration of reactants. We can also increase the rate of a reaction by increasing temperature to safe levels.
In the reaction mentioned in the question, Mg + 2HCl → MgCl2 + H2, if we increase the amount of magnesium or HCl, the reaction will proceed faster. Similarly, if we increase the temperature, then also the reaction rate will increase.
Answer:
dinitrogen tetrachloride, ionic
Explanation:
N2Cl4
N2 should be dinitrogen since the N is nitrogen and the 2 is for 2 of the Ns.
Cl4 (the second part of the compound) should be named like an ion and the prefix. for the prefix: tetra (since there are 4) and chlorIDE since we are naming it like an ion. So Cl4 becomes tetrachloride.
In the end, the compound should be named dinitrogen tetrachloride.
For the second part, I think because Cl is included, and it's charge is -, the bond should be ionic. N can form ionic or covalent bonds.
The bond between N2 and Cl4 is ionic.
The order of decreasing energy is ultraviolet rays, infrared rays, and microwaves.
Frequency is defined as the number of occurrences of the event. In wave function, frequency is the number of times the given waveform passes through a given point. The SI unit of frequency is Hertz.
Photons are particles that do not contain mass but possess energy. Photon energy is calculated by the formula Planck's constant h ( 6.63✖10-34 J/s) multiplied by the frequency. Hence frequency is directly proportional to the energy of the photon.
Higher frequency waves will have higher energy. Lower frequency waves will have lower energy.
