Answer:
153.3 grams of ZrCl₄ are produced
Explanation:
The equation of the reaction is as follows:
ZrSiO₄ + Cl₂ ----> ZrCl₄ + SiO₂ + O₂
molar mass of ZrSiO₄ = (91 + 32 + 16 * 4) = 187.0 g/mol
molar mass of ZrCl₄ = (91 + 35.5 * 4) = 233.0 g/mol
molar mass of Cl₂ = (35.5 * 2) 71.0 g/mol
From the equation of reaction, 1 mole of ZrSiO₄ reacts with one mole of Cl₂ to produce one mole of ZrCl₄
number of moles of ZrSiO₄ present in 123 g = 123/187 = 0.65 moles
number of moles of Cl₂ present in 85.0 g = 85.0/71.0 = 1.19 moles
therefore, ZrSiO₄ is the limiting reactant
123.0 g of ZrSiO₄ will react with excess Cl₂ to produce 123 * 233/187 grams of ZrCl₄ = 153.3 grams of ZrCl₄
Therefore, 153.3 grams of ZrCl₄ are produced

How does the angle of the incoming light affect the intensity of the light that is refracted?
Answer:
A reflected ray always comes off the surface of a material at an angle equal to the angle at which the incoming ray hit the surface. In physics, you'll hear this called the law of reflection. You've probably heard this law stated as "the angle of incidence equals the angle of reflection

A metal crystallizes in the face‑centered cubic (FCC) lattice. The density of the metal is 12020 kg/m3, and the length of a unit cell edge, , is 389.08 pm. Calculate the mass of one metal atom in grams.
Identify the metal. either ( gold, silver, platinum, palladium)
Answer:
the metal is gold I'd say
The mass of one metal atom is [tex]1.770\times 10^{-22}[/tex]grams.
The metal atom is palladium.
Explanation:
Given:
A face-centered unit cell.
The density of the unit cell is [tex]12020 kg/m^3[/tex].
The edge length of the unit cell 389.08 pm
To find:
The mass of one atom of the metal
Solution:
The density of the unit cell = d = [tex]12020 kg/m^3[/tex]
The edge length of the unit cell = a = 389.08 pm
[tex]1 pm = 10^{-12} m\\a=389.08 pm=389.08\times 10^{-12} m=3.8908\times 10^{-10}m[/tex]
Total number of atoms in F.C.C unit cell = z = 4
The atomic mass of the metal atom = M
The density of the unit cell is given by:
[tex]d=\frac{z\times M}{N_A\times a^3}\\12020 kg/m^3=\frac{4\times M}{6.022\times 10^{23}mol^{-1}\times (3.8908\times 10^{-10}m)^3}\\M=0.106586 kg/mol\\1 kg=1000 g\\M=0.106586 kg/mol=0.106586 \times 1000 g/mol\\M=106.586 g/mol[/tex]
The mass of one mole of metal atom = 106.586 g
The mass of 1 atom of metal :
[tex]=\frac{106.586 g}{6.022\times 10^{23}}\\=1.770\times 10^{-22} g[/tex]
The mass of one metal atom is [tex]1.770\times 10^{-22}[/tex] grams.
The atomic mass of the metal atom is 106.586 g/mol which is close to the atomic mass of the palladium. Hence, the metal atom is palladium.

(ii) When shale gas is burned, the hydrogen sulfide reacts with oxygen.
2H2S + 3022SO2 + 2H2O
Explain how the combustion of shale gas can lead to the formation of acid rain.
Answer:
See explanation
Explanation:
Now , we have the equation of the reaction as;
2H2S(g) + 302(g)------->2SO2(g) + 2H2O(g)
This equation shows that SO2 gas is produced in the process. Let us recall that this same SO2 gas is the anhydride of H2SO4. This means that it can dissolve in water to form H2SO4
So, when SO2 dissolve in rain droplets, then H2SO4 is formed thereby lowering the pH of rain water. This is acid rain.

determine the density of an object that is 25 cm long 10 cm wide and 2 cm high with a mass of 50 g
Answer:
[tex]\boxed {\boxed {\sf \rho= 0.1 \ g/cm^3 }}[/tex]
Explanation:
Density is found by dividing the mass by the volume.
[tex]\rho=\frac{m}{v}[/tex]
The mass is 50 grams, but we have to find the volume.
Assuming this is a solid rectangular object, we can use this formula for volume:
[tex]v=l*w*h[/tex]
The length is 25 centimeters, the width is 10 centimeters, and the height is 2 centimeters.
[tex]v= 25 \ cm * 10 \ cm * 2 \ cm[/tex]
[tex]v= 250 \ cm^2 * 2 \ cm[/tex]
[tex]v= 500 \ cm^3[/tex]
Now we know the mass and volume:
[tex]m= 50 \ g\\v= 500 \ cm^3[/tex]
Substitute the values into the formula.
[tex]\rho = \frac{50 \ g}{500 \ cm^3}[/tex]
[tex]\rho= 0.1 \ g/cm^3[/tex]
The density of the object is 0.1 grams per cubic centimeter.

Describe the relationship between speed and kinetic energy.
A) A positive linear relationship
B) A negative linear relationship
C) A negative but not linear relationship
D) A positive but not linear relationship
Answer:
D) A positive but not linear relationship
Explanation:
This comes from the equation Ek=1/2mv^2
Where Ek is Kinetic Energy, m is mass, and v is the speed (or velocity).
As we can see in the equation, the relation is not linear but quadratic and it is positive.
Answer:
D) A positive but not linear relationship
Explanation:
Speed is equal to distance divided by time. ... Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four.

Calculate the percent of each component in the mixture. Show your calculations. Circle final answers.
Answer:
See Explanation
Explanation:
The question is incomplete; as the mixtures are not given.
However, I'll give a general explanation on how to go about it and I'll also give an example.
The percentage of a component in a mixture is calculated as:
[tex]\%C_E = \frac{E}{T} * 100\%[/tex]
Where
E = Amount of element/component
T = Amount of all elements/components
Take for instance:
In [tex](Ca(OH)_2)[/tex]
The amount of all elements is: (i.e formula mass of [tex](Ca(OH)_2)[/tex])
[tex]T = 1 * Ca + 2 * H + 2 * O[/tex]
[tex]T = 1 * 40 + 2 * 1 + 2 * 16[/tex]
[tex]T = 74[/tex]
The amount of calcium is: (i.e formula mass of calcium)
[tex]E = 1 * Ca[/tex]
[tex]E = 1 * 40[/tex]
[tex]E = 40[/tex]
So, the percentage component of calcium is:
[tex]\%C_E = \frac{E}{T} * 100\%[/tex]
[tex]\%C_E = \frac{40}{74} * 100\%[/tex]
[tex]\%C_E = \frac{4000}{74}\%[/tex]
[tex]\%C_E = 54.05\%[/tex]
The amount of hydrogen is:
[tex]E = 2 * H[/tex]
[tex]E = 2 * 1[/tex]
[tex]E = 2[/tex]
So, the percentage component of hydrogen is:
[tex]\%C_E = \frac{E}{T} * 100\%[/tex]
[tex]\%C_E = \frac{2}{74} * 100\%[/tex]
[tex]\%C_E = \frac{200}{74}\%[/tex]
[tex]\%C_E = 2.70\%[/tex]
Similarly, for oxygen:
The amount of oxygen is:
[tex]E = 2 * O[/tex]
[tex]E = 2 * 16[/tex]
[tex]E = 32[/tex]
So, the percentage component of oxygen is:
[tex]\%C_E = \frac{E}{T} * 100\%[/tex]
[tex]\%C_E = \frac{32}{74} * 100\%[/tex]
[tex]\%C_E = \frac{3200}{74}\%[/tex]
[tex]\%C_E = 43.24\%[/tex]
