Tara is performing a chemical experiment, at one point she needed to know whether the solution is acidic or basic so she used the PH meter to measure the solution. She got a reading of 13.4,

1. Is the solution acidic or base? Explain why.

2. What will happen to the PH when she will add water to the solution?

Answers

Answer 1

It is a base because its pH is greater than 7

(not sure about the second sorry!)

In a lab, students measured the mass of an unknown metal to be 46.4g The metal sample releases 769 J when it is cooled from 101.0°C to 30.00 "C, the
meal is most likely?

Lead
Copper
Mercury
Silver

Answers

From Q = mcΔΤ, the specific heat capacity, c, of the metal that was cooled is c = Q/mΔT = (-769 J)/(46.4 g)(30.0 °C - 101.0 °C) = 0.233 J/g °C. From the table, it appears that this is the specific heat capacity of silver. So, the metal is most like silver.

Note: The value for Q was written as a negative value in the equation as heat energy was given off by the metal when the metal was cooled (from the metal’s point of view, it’s losing heat energy).

How many moles of calcium nitrate would react with 4.55 moles of chromium (III) sulfate to produce calcium sulfate and chromium(III) nitrate?

Answers

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?

Answers

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).

What is tugror pressure ,what causes it,and what does it do for a plant?

Answers

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?

Answers

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.
