No because it is a gas so (in space) so, it would most likely stay in one place. Your welcome!
In the technique of recrystallization "the mother liquor is the filtrate".
<u>Option: </u>C
<u>Explanation:</u>
The portion of a solution remaining over after crystallization is understood as a mother liquor. It is found in chemical reactions that include sugar refining. It is the liquid produced by filtration of the crystals. The residual liquid, once the crystals have been extracted out as the mother liquor will include a portion of the initial solution as estimated at that temperature by its solubility as well as any unfiltered contaminants. Second and third crystal crops can then be collected from the mother's liquor.
Answer:
The average atomic mass is 126.1
Explanation:
To obtain the atomic mass of the isotope we use this formula;
(% composition of isotope 1 * mass number) + (% composition of isotope 2 * mass number)
1. Equate the percentage composition with the mass number of each isotope
45/100 * 125 = 56.25
55/100 * 127 = 69.85
2. Add both answers together you get,
56.25 + 69.85 = 126.1.
The average atomic mass is therefore 126.1
Answer:
Phosphorus
Explanation:
In given diagram there are 15 electrons are present. Which means it is orbital diagram of phosphorus.
The atomic number of phosphorus = 15
Number of electrons = 15
Electronic configuration of phosphorus:
P₁₅ = 1s² 2s² 2p⁶ 3s² 3p³
All other options are incorrect because:
Calcium have 20 electrons.
Electronic configuration of Ca:
Ca₂₀ = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s²
Hydrogen have one electron.
Electronic configuration of H.
H₁ = 1s¹
Magnesium have 12 electrons:
Electronic configuration of Mg:
Mg₁₂ = 1s² 2s² 2p⁶ 3s²
Answer:
by using ideal gas law
Explanation:
ideal gas law:
PV=nRT
where:
P is pressure measured in Pascal (pa)
V is volume measured in letters (L)
n is number of moles
R is ideal gas constant
T is temperature measured in Kelvin (K)
by applying the given:
P(initial) V(initial)=nRT(initial)
P(final) V(final)=nRT(final)
nR is constant in both equations since same gas
then,
P(initial) V(initial) / T(initial) = P(final) V(final) / T(final)
then by crossing multiply both equations
V (final)= { (P(initial) V(initial) / T(initial)) T(final) } /P (final)
P(initial)=P(final)= 1 atm = 101325 pa
V(initial)= 6 L
T(initial) = 28°c = 28+273 kelvin
T(final) = 39°c = 39+273 kelvin
by substitution
V(final) = 6.21926 L
