Answer:

0.348 L

Explanation:

Step 1: Given data

Step 2: Calculate the volume of the concentrated solution

We want to prepare a dilute solution from a concentrated one. We can calculate the volume of the concentrated solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

V₁ = C₂ × V₂ / C₁

V₁ = 1.07 M × 2.11 L / 6.49 M = 0.348 L

93.5 is the percent yield for this reaction.

The theoretical yield is the maximum possible mass of a product that can be made in a chemical reaction.

Step 1: Solve for the mass of CH_2O produced.

Mass [tex]CH_2O[/tex] = 15.4 g [tex]CH_3OH[/tex] × (1 mol [tex]CH_3OH[/tex] ÷ 32.04 g [tex]CH_3OH[/tex]) × (1 mol [tex]CH_2O[/tex] ÷ 1 mol [tex]CH_3OH[/tex]) × (30.03 g [tex]CH_2O[/tex] ÷ 1 mol [tex]CH_2O[/tex])

Mass [tex]CH_2O[/tex]= 14.43 g

Step 2: Determine the theoretical yield.

Theoretical yield = mass [tex]CH_2O[/tex]

Theoretical yield = 14.43 g

Step 3: Solve for the percent yield.

Percent yield = (actual yield ÷ theoretical yield) × 100

Percent yield = (13.5 g ÷ 14.43 g) × 100

Percent yield = 0.9355509356 × 100 =93.5  percent

Hence, 93.5 is the percent yield for this reaction.

Answer:

Limiting reagent is Na

Explanation:

Reaction of Na with water is:

Na + H₂O →  NaOH  +  H₂

It is a very exothermic reaction.

The correctly balanced equation is:

2Na + 2H₂O →  2NaOH  +  H₂

Ratio is 2:2, between reactants, according to stoichiometry.

We convert mass to moles:

22 g . 1 mol / 23 g = 0.956 moles of Na

28 g . 1mol / 18 g = 1.56 moles of water.

Certainly the limiting reagent is sodium. For 1.56 moles, we need the same amount of sodium and we only have 0.956 moles.

We do not have enough sodium to complete the reaction.

Answer:

Yes I would believe that this report was true, because nobody would lie on a news channel that they cured cancer and then not cure it. That would completely ruin their credibility as well as the news channels credibility. So no news channel would take the story if it was made up.

I would like to see there studies on how the medicine kills off the cancer and the side effects of the medicine on the human body. I would want to know how the medicine is made, if its FDA approved, and how the medicine will be distributed across the globe and at what prices, as well as how easily the medicine expires.

Answer:

Explanation:

I will probably believe the report but want to find out more details. First is cure for which cancer has been found. Cancer is a general name for a large family of different diseases. So it is very likely that the cure is for some specific cancers.

Secondly I want to know if the cure has any side effect. The typical treatments for cancer now are radiation and chemo therapy. Both can cause serious side effects.

Lastly the cost of cure is important. New drugs with patent protection can be very expensive which limit on how many people can afford the treatment.

When NaOH is an Arrhenius base so it is dissociated in water so the given statement is false.

It is this base since it dissociates in water to provide the hydroxide (OH-) and sodium (Na+) ions.

It is the substance that is ionized at the time when it is dissolved in water to provide the hydrogen ion.

hence, the given statement is false.

Explanation:

A molecular equation is a balanced chemical equation which shows the reacting species as molecules rather than as componenet ions in their compounds with subscripts written beside the molecules to indicate the state in which they occur in the chemical reaction.

An ionic equation expresses the reacting species as components ions in a chemical reation. All the ions and molecules reacting are shown.

In a net ionic equation, the ions which remain in the ionic state also known as spectator ions are not written as part of the equation.

Answer:

[Cr(NH3)6.]C13

Explanation:

Alfred Werner's coordination theory (1893) recognized two kinds of valency;

Primary valency which are nondirectional and secondary valency which are directional.

Hence, the number of counter ions precipitated from a complex depends on the primary valency of the central metal ion in the complex.

We must note that it is only these counter ions that occur outside the coordination sphere that can be precipitated by AgNO3.

If we consider the options carefully, only [Cr(NH3)6.]C13 possess counter ions outside the coordination sphere which can be precipitated when treated with aqueous AgNO3.

Example : H2O (water) There are 2 atoms of Hydrogen and 1 atom of Oxygen in this substance

Answer:

protons: positively charged, located in the nucleus

electrons: negatively charged, located outside the nucleus

neutrons: no charge, located in the nucleus

Answer:

The electrons will be added by the hydrogen.

Explanation:

If we fire a single electron towards the hydrogen atom, the hydrogen atoms added the electron to its shell by applying force of attraction and becomes stable as well as non reactive in nature because the hydrogen attains the electronic configuration of helium which is a noble gas and have completed its outermost shell. The proton that is present in the nucleus attracts this electron and compel it to add in the electron.

Answer:

7505.19 J

Explanation:

We'll begin by calculating the change in the temperature of copper. This can be obtained as follow:

Initial temperature (T₁) = 20 °C

Final temperature (T₂) = 875 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 875 – 20

ΔT = 855 °C

Finally, we shall determine the heat required. This can be obtained as follow:

Specific heat capacity (C) = 0.385 J/gºC

Change in temperature (ΔT) = 855 °C

Mass (M) = 22.8 g

Heat (Q) required =?

Q = MCΔT

Q = 22.8 × 0.385 × 855

Q = 7505.19 J

Thus, 7505.19 J of heat energy is required.

.....how

Answer:

A 1.0 g sample of propane, C3H8, was burned in the calorimeter.

The temperature rose from 28.5 0C to 32.0 0C and the heat of combustion 10.5 kJ/g.

Calculate the heat capacity of the calorimeter apparatus in kJ/0C

Explanation:

[tex]Heat of combustion = heat capacity of calorimeter * deltaT\\[/tex]

Given,

The heat of combustion = 10.5kJ/g.

[tex]deltaT = (32.0-28.5)^oC\\deltaT = 3.5^oC[/tex]

Substitute these values in the above formula to get the value of heat capacity of the calorimeter.

[tex]deltaT =heat capacity of calorimeter * (change in temperature)\\10.5kJ/g = heat capacity of calorimeter * (3.5^oC)\\\\=>heat capacity of calorimeter = \frac{10.5kJ/g}{3.5^oC} \\=>heat capacity of calorimeter = 3.0 kJ/g.^oC[/tex]

Answer:

The heat capacity of the calorimeter is [tex]3.0kJ/g.^oC.[/tex]
