How many moles of calcium nitrate would react with 4.55 moles of chromium (III) sulfate to produce calcium sulfate and chromium(III) nitrate?
Answer:
13.65 moles
Explanation:
The equation of the reaction is;
3Ca(NO3)2 + Cr2(SO4)3 = 3Ca(SO4) + 2 Cr(NO3)3
4.55 moles of chromium (iii) sulfate reacts with calcium nitrate
The mole ratio of Chromium (iii) sulfate to calcium nitrate is 1: 3
Therefore; the moles of calcium nitrate will be given by
= (4.55/ 1)×3
= 13.65 moles
Hence; 13.65 moles of calcium nitrate would react with 4.55 moles of Chromium (iii) sulfate.
If a 28.0 L balloon with a temperature of
25 °C is cooled in a refrigerator, what will
be the volume of the balloon be when it
reaches 5 °C?
Answer:
5.6 L
Explanation:
We can apply Charles' Law here since our pressure is constant (will not change inside the refrigerator) and we are relating change in volume with change in temperature:
V₁ / T₁ = V₂ / T₂ where V₁ and T₁ are initial volume and temperature, and V₂ and T₂ are final volume and temperature. Let's plug in what we know and solve for the unknown:
28.0 L / 25 °C = V₂ / 5 °C => V₂ = 5.6 L
5.6 L is our new volume (at 5 °C).
Why is methanol written as ch3oh instead of ch4o?
Answer: Here comes the role of another formula, which we refer to as the structural formula and that is CH3OH for methanol. The structural formula gives us an additional information that carbon is attached to three hydrogen atoms and one oxygen atom.

The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.
What is a Chemical reaction?Chemical reaction refers to reaction that take place between reacting substances in which the chemical substances are transformed to products.
When the concentration of the reactants increases, more molecules tend to interact with each other in order to form new compounds, and the rate of reaction increases. When the concentration of the reactants reduces, there are little of that molecule present, and the rate of reaction decreases
Therefore, The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.

Why might the ability to produce three-dimensional images of organs be helpful in diagnosing a patient's ailment?
Answer:
Explanation: The body is largely composed of water molecules. Each water molecule has two hydrogen nuclei or protons. MRI takes advantage of the high prevalence of hydrogen in the body and the magnetic properties of the proton in a hydrogen atom. Hydrogen atoms induce a small magnetic field due to the spin of this atom's proton.

What is tugror pressure ,what causes it,and what does it do for a plant?
Answer:
Explanation:
Turgor pressure is the pressure forced or in other words, exerted onto the cell wall of the plant. It's caused by the movement of water into the cell. This causes the water to rush and burst into the cell, which increases the pressure onto the cell wall. Due to that, cell swells up, which helping the plant to stand upright and straight.

Create the Equation: How many grams of Aluminum Chloride would be made from 42.7 L of Chlorine gas at STP reacting with 50.0 g of Aluminum?
Answer: 169.3 g of [tex]AlCl_3[/tex] will be produced
Explanation:
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
moles of [tex]Al[/tex]
[tex]\text{Number of moles}=\frac{50.0g}{27g/mol}=1.85moles[/tex]
moles of [tex]Cl_2[/tex]
According to ideal gas equation:
[tex]PV=nRT[/tex]
P = pressure of gas = 1 atm (STP)
V = Volume of gas = 42.7 L
n = number of moles = ?
R = gas constant =[tex]0.0821Latm/Kmol[/tex]
T =temperature =[tex]273K[/tex] (at STP)
[tex]n=\frac{PV}{RT}[/tex]
[tex]n=\frac{1atm\times 42.7L}{0.0820 L atm/K mol\times 273K}=1.90moles[/tex]
[tex]2Al+3Cl_2\rightarrow 2AlCl_3[/tex]
According to stoichiometry:
3 moles of [tex]Cl_2[/tex] reacts with = 2 moles of aluminium
Thus 1.90 moles of [tex]Cl_2[/tex]reacts with= [tex]\frac{2}{3}\times 1.90=1.27[/tex] moles of aluminium
Thus [tex]Cl_2[/tex] is the limiting reagent as it limits the formation of product.
As 3 moles of [tex]Cl_2[/tex] give = 2 moles of [tex]AlCl_3[/tex]
Thus 1.90 moles of [tex]Cl_2[/tex] give =[tex]\frac{2}{3}\times 1.90=1.27moles[/tex] of [tex]AlCl_3[/tex]
Mass of [tex]AlCl_3=moles\times {\text {Molar mass}}=1.27moles\times 133.34g/mol=169.3g[/tex]
Thus 169.3 g of [tex]AlCl_3[/tex] will be produced from the given masses of both reactants.
