Answer:

When you move the burette slider to the top of a flask and add about 25 mL of NaOH to the flask, you will cause a concentration of OH- molecules. This will make the solution become a basic solution and make the litmus paper blue.

Explanation:

After reading your question, we can see that you are carrying out a test to discover the nature of the pH of a solution. This type of test uses litmus paper, which is an indicator of the presence of acids and bases, being able to determine the pH of a solution. This paper is soaked in organic ink and when placed in an acidic solution, it is red in color. However, when placed in a basic solution it has a blue color.

An acidic solution is one that has a high concentration of H+ atoms and has the ability to donate electrons. The basic solution, on the other hand, has a high concentration of OH- and has the capacity to receive electrons.

When you move the burette slider to the top of a flask and add about 25 mL of NaOH to the flask, you will cause a concentration of OH- molecules. This will make the solution become a basic solution and make the litmus paper blue, that is, the solution has the basic pH.

Explanation:

When you use electricity to charge your car, you can integrate renewable resources like solar into the fueling process. Without solar, your electric vehicle is still effectively running off of fossil fuels – it's just the fossil fuels utilized at the power plant and not within your engine.

Fossil fuels include substances like natural gas, coal, and oil. It is possible for electric cars to run on these fossil fuels. Fossil fuels like coal are burnt up to generate electricity. So when cars run on electricity, they are indirectly tapping into fossil fuels.

Answer: The forces of attraction are stronger in new attractions that are formed.

Explanation:

When a chemical reaction takes place between two or more different compounds then less reactive substance is displaced by the more reactive substance.

During this process, when bonds are broken between the reactants then it means the force of attraction is less stronger. The formation of new compounds occur because force of attraction is more in these new substances due to which its atoms come closer to each other.

Thus, we can conclude that forces of attraction are stronger in new attractions that are formed.

Explanation:

N2(g) + 3 H2(g) → 2 NH3 (g) balanced equation

First, find limiting reactant:  

Moles H2 = 1.83 g x 1 mole/2 g = 0.915 moles H2

Moles N2 = 9.84 g N2 x 1 mole/28 g = 0.351 moles N2

The mole ratio of H2: N2 is 3:1, so H2 is limiting (0.915 is less than 3 x 0.351)

Theoretical yield of NH3 = 0.915 mol H2 x 2 mol NH3/3 mol H2 = 0.61 moles NH3

Explanation:

By using pH formula, the concentration of hydroxyl ion [OH-] will be 5.3 ×[tex]10^{-4}[/tex] M.

What is pH?

The pH scale is a measurement of hydrogen ion concentration that is used to determine the acidity as well as alkalinity of a solution.

Calculation of [OH-] by using formula of pH.

Given data:

[H+] = 1.87 x [tex]10^{-11} M[/tex]

[OH-] = ?

Calculation of [OH-] is shown below:

It can be calculated by using the formula:

pH = -log [H+]

Put the value of concentration of hydrogen ion [H+]  in above formula.

pH = -log (1.87 x [tex]10^{-11} M[/tex])

pH = -log (1.87) -log ( [tex]10^{-11} M[/tex])

pH = -0.27 +11

pH = 10.73

Now, use the formula, pH +pOH = 14

pOH = 14 - pH

pOH = 14 - 10.73

pOH = 3.27

Now, use formula pOH = -log [OH-]

[OH-] = [tex]10^{-pOH}[/tex]

[OH-] = [tex]10^{-3.27}[/tex]

[OH-] = 5.3 ×[tex]10^{-4}[/tex] M

Therefore, the concentration of hydroxyl ion [OH-] will be 5.3 ×[tex]10^{-4}[/tex] M.

Answer: [tex]2Bi(NO_3)_5(aq)+5Sr(OH)_2(aq)\rightarrow 2Bi(OH)_5(s)+5Sr(NO_3)_2(aq)[/tex]

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.  

The balanced chemical equation is:

Answer:

V=0.430 Liters

Explanation:

First off you need to convert ml to l and celsius to kelvin, in order for them to be in the S.I.

So, 350.0mL is 0.350 L and 23.0 C is (273.15+23=) 296.15 K (you can ignore the 0.15)

From the equation pV=nRT, lets name this equation (1),  we can tell that the number of moles, pressure, and R, stay the same. The only thing changing is the volume, and temperature.

With the information given, let's figure out the pressure. From equation (1) if we solve it for the pressure of the gas, p=nRT/V => p=nR*296.15/0.350 => p=846.15 *nR

Now, we have to figure out the volume of the gas at 90.0 C (363.15 K), and solve equation (1) for volume, using the pressure we previously found.

v=nRT/p => v=nR*363.15/846.15*nR => (the nR's from top and bottom go away) v=0.429 L

Since we used 273.15 for the conversion of celsius to Kelvin, we could round up the number to

V=0.430 Liters

Answer:

670.45 K

Explanation:

Given that,

Initial volume, V₁ = 1.22 L

Initial temperature, T₁ = 286 K

Final volume, V₂ =  2.86 L

We need to find the new temperature of the gas. The relation between the volume and the temperature is given by :

[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{2.86\times 286}{1.22}\\\\T_2=670.45\ K[/tex]

So, the new temperature of the gas is equal to 670.45 K.

Answer:

22.9 Liters CO(g) needed

Explanation:

2CO(g)     +   O₂(g)    =>    2CO₂(g)

? Liters          32.65g

                 = 32.65g/32g/mol

                 =   1.02 moles O₂

Rxn ratio for CO to O₂ = 2 mole CO(g) to 1 mole O₂(g)

∴moles CO(g) needed = 2 x 1.02 moles CO(g) = 2.04 moles CO(g)

Conditions of standard equation* is STP (0°C & 1atm) => 1 mole any gas occupies 22.4 Liters.

∴Volume of CO(g) = 1.02mole x 22.4Liters/mole = 22.9 Liters CO(g) needed

*Standard Equation => molecular rxn balanced to smallest whole number ratio coefficients is assumed to be at STP conditions (0°C & 1atm).

Answer:

4118.2

Explanation:

Given: 29 moles of na²[tex]So^{4}[/tex]

To find: In grams.

Solution: Wrong

If 1 na²[tex]So^{4}[/tex] is 142 grams, then 29 grams will be found if a set of fraction has been set up;

Let [tex]"x"[/tex] be the variable

[tex]\frac{142}{1} = \frac{29}{x}[/tex]

Cross multiply

[tex]\frac{142}{29}[/tex] [tex]= 4.9[/tex]

Correct Solution

Multiply 29 by 142 = 4118
