Answer: Mass of diborane that would react with 7.5 mole of O2 is 70g
Explanation: The explanation is contained in the picture attached.
Answer:
The other colors of the electromagnetic spectrum are absorbed by the substance and not reflected. If you were to look at it in infared or unltraviolet it would reflect different colors than those of the visible spectrum.
Explanation:
The magnetic quantum
number <span>is one of four quantum numbers which are
assigned to each electron in an atom to describe that electron's
state.
The magnetic quantum number (ml) can be any
integer between -l and +l.
Magnetic quantum number specify orientation of electrons in magnetic
field and number of electron states (orbitals) in subshells.
Magnetic quantum number (ml) specifies the orientation in space of an orbital
of a given energy and shape . Magnetic quantum number divides the subshell
into individual orbitals which hold the electrons, there are 2l+1 orbitals in
each subshell.
For 5p orbital electrons:
Principal quantum n = 5.
Angular quantum number l = 1.
<span>Magnetic quantum number ml = -1, 0, +1.</span></span>
The correct answer is NH₄Cl.
With the increase in temperature, endothermic reactions are favored. The dissolution of NH₄Cl in water is an example of an endothermic reaction. When the temperature is increased more dissolution of the salt takes place, thus, the solubility of the salt increases.
Hence, it can be said that NH₄Cl will exhibit the greatest change in the solubility per 100 g solvent with an elevation in temperature.
Answer:
V2= 5L
Explanation:
P1= 500kPa, V1= 3L, P2= 300kPa, V2=?
Applying Boyle's law
P1V1=P2V2
(500*3)= (300*V2)
V2= 5L
