Answer: D. 1600 L
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given volume}}{\text {Molar volume}}[/tex]
[tex]\text{Number of moles of nitrogen}==\frac{1000L}{22.4L}=44.6moles[/tex]
[tex]\text{Number of moles of hydrogen}==\frac{2400L}{22.4L}=107.1moles[/tex]
[tex]N_2(g)+3H_2(g)\rightarrow 2NH_3(g)[/tex]
According to stoichiometry :
3 moles of [tex]H_2[/tex] require 1 mole of [tex]N_2[/tex]
Thus 107.1 moles of [tex]H_2[/tex] will require=[tex]\frac{1}{3}\times 107.1=35.7moles[/tex] of [tex]N_2[/tex]
Thus [tex]H_2[/tex] is the limiting reagent as it limits the formation of product and [tex]N_2[/tex] is the excess reagent.
As 3 moles of [tex]H_2[/tex] give = 2 moles of [tex]NH_3[/tex]
Thus 107.1 moles of [tex]H_2[/tex] give =[tex]\frac{2}{3}\times 107.1=71.4moles[/tex] of [tex]NH_3[/tex]
Volume of [tex]NH_3=moles\times {\text {Molar volume}}=71.4moles\times 22.4L/mol=1600L[/tex]
Thus volume of ammonia produced is 1600 L

'Scientists believe another Pangea is in Earth’s future. Explain why the evidence of tectonic plate motion supports this belief.'
help please and thank you
Answer:
eu nu insteleg ce zite
Explanation:
Answer:
We know that the movement of tectonic plates is a continuous process. Divergent plates cause the ocean floor to expand. Because of slab pull, subduction, and other processes, the landmasses keep drifting. Because of these movements, continents are continually moving apart from each other. It’s possible that one day they will collide to form a giant landmass and become another Pangea.

Which alkaline earth metal has the highest ionization energy? Refer to the periodic table.
calcium
magnesium
barium
strontium
The highest ionization energy of alkaline earth metal is calcium. Therefore, option (A) is correct.
What is the ionization energy?The ionization energy can be described as the minimum energy that an electron has to absorb to come out of the effect of the nucleus of a gaseous atom or ion.
It tells about the reactivity of chemical compounds and determines the strength of chemical bonds. The units of ionization energy are electronvolts or kJ/mol.
Ionization energy measures the difficulty in removing an electron from an atom or ion and the loss of electron occurs in the ground state of the chemical species.
According to the general configuration of alkaline earth metals, they contain two electrons in their valence shell. The atomic size of alkaline earth metals increases as we move down the group. The electronegativity and effective nuclear charge of alkaline earth metals decrease.
The electron can easily be lost from the atom as we move down the group. Therefore, calcium present at the top of the group has the highest ionization energy.

Calculate the new volume in liters of a 0.500 L water bottle at 25.0 degrees when the plastic bottle is submerged in ice water at 1.00 degree Celsius.
Answer:
0.02L
Explanation:
Using the formula V1/T1 = V2/T2
Given
V1 = 0.5L
T1 = 25 degrees
T2 = 1 degree
V2 =?
Substitute
0.5/25 = V2/1
Cross multiply
25V2 = 0.5
V2 = 0.5/25
V2 = 0.02L
Hence the new volume will be 0.02L

Answer:
2 chloride ion, Cl¯
Explanation:
The formula for calcium chloride is CaCl₂.
Next, we shall write the balanced dissociation equation for calcium chloride, CaCl₂. This is illustrated below:
CaCl₂ (aq) —> Ca²⁺ + 2Cl¯
From the balanced equation above,
We can see that calcium chloride, CaCl₂ contains 1 calcium ion, Ca²⁺ and 2 chloride ion, Cl¯.
Therefore, we can conclude that for every 1 calcium ion, Ca²⁺, there are 2 chloride ion, Cl¯.

A student dissolves 13. g of stilbene (C14H12) in 100. mL of a solvent with a density of 0.85 g/mL. The student notices that the volume of the solvent does not change when the stilbene dissolves in it.
Calculate the molarity and molality of the student's solution. Be sure each of your answer entries has the correct number of significant digits.
Answer:
Molarity = 0.72M
Molality = 0.85M
Explanation:
Molarity and molality are two measures of molar concentration, and they can be calculated as follows:
Molarity = number of moles/volume of solvent
Molality = number of moles/mass (kg) of solvent
Mole = mass/molar mass
Molar mass of stilbene (C14H12) = 12(14) + 1(12)
= 168 + 12
= 180g/mol
mole of stilbene = 13/180
mole = 0.072mol
Volume = 100mL = 0.1L
molarity = 0.072/0.1
Molarity = 0.72M
Molality = number of moles ÷ mass (kg) of solvent
To get mass of solvent, we use;
Density = mass/volume
Mass = density × volume
Mass = 0.85g/mL × 100mL
Mass = 85g
Mass in kg = 85/1000 = 0.085kg
Molality = 0.072/0.085
Molality = 0.847M
Molality = 0.85M
