what is the difference between quantative and qualitative analysis​

Answers

Answer:

Quantitative data can be counted, measured, and expressed using numbers.  Qualitative data is descriptive and conceptual.  Qualitative data can be categorized based on traits and characteristics.

Explanation:

Quantitative analysis involves looking at the hard data, the actual numbers. Qualitative analysis is less tangible. It concerns subjective characteristics and opinions – things that cannot be expressed as a number.

How many grams of KCl are made when 5.02 moles of

lol pls help me

Answers

Answer: 747.98 grams of KCl are made when 5.02 moles of  [tex]ZnCl_2[/tex] react in the reaction.

Explanation:

The balanced chemical equation is:

[tex]2KMnO_4+ZnCl_2\rightarrow 2KCl+Zn(MnO_4)_2[/tex]

According to stoichiometry:

1 mole of [tex]ZnCl_2[/tex] produce = 2 moles of [tex]KCl[/tex]

Thus 5.02 moles [tex]ZnCl_2[/tex] will produce =[tex]\frac{2}{1}\times 5.02=10.04[/tex] moles of [tex]KCl[/tex]

Mass of [tex]KCl=moles\times {\text {molar mass}}=10.04mol\times 74.5g/mol=747.98g[/tex]

Thus 747.98 grams of KCl are made when 5.02 moles of  [tex]ZnCl_2[/tex] react in the reaction.

What is the volume, in L, of 2.50 moles of oxygen gas measured at 25.0oC and a pressure of 104.5 kPa?

Answers

Answer:

58.53 L

Explanation:

Ideal gas equation is

PV = nRT

P - the pressure of the gas = 104.5  KPa

V- the volume occupied by the gas

n  - the number of moles of gas =2.50

R - the universal gas constant, usually given as  0.0821 atm.L/(mol K)

T - the absolute temperature of the gas.= 298K

[tex]V =\frac{nRT}{P}[/tex]

Now substituting vales we get

[tex]V = \frac{2.5\times0.0821\times298}{104.5\times1000}[/tex]

V = 58.53 L

There are moles of carbon present in 100 g of a
compound with the following percentage composition:
C= 40.0%, H = 6.72%, O = 53.29%.

Answers

Answer: 3.33

Explanation:

The molecular formula of the given composition is C₃H₆O₃.

What is molecular formula?

Molecular formula is defined as a compound's chemical formula, which counts the total number of each element present in a molecule of the compound as discrete molecules. The arrangement of atoms in a molecule in three dimensions is known as molecular geometry, commonly referred to as the molecular structure.

The percentage composition is

C = 40.00 %

H = 6.72 %

O = 53.29 %

Mole = 100 g

Mass of C = 40 / 100 x 100 = 40 g

mass of H = 6.72 / 100 x 100 = 6.72 g

Mass of O = 53.29 / 100 x 100 = 53.29 g

Dividing the mass with moles

C = 40 / 12 = 3.3

H = 6.72 / 1 = 6.72

O = 53.29 / 16 = 3.3

Formula = C₃H₆O₃

Thus, the molecular formula of the given composition is C₃H₆O₃.

A study was conducted to see if increasing the substrate concentration has an appreciable effect on the velocity of a chemical reaction. With a substrate concentration of 1.5 moles per liter, the reaction was run 15 times, with an average velocity of 7.5 micromoles per 30 minutes and a standard deviation of 1.5. With a substrate concentration of 2.0 moles per liter, 12 runs were made, yielding an average velocity of 8.8 micromoles per 30 minutes and a sample standard deviation of 1.2. Is there any reason to believe that this increase in substrate concentration causes an increase in the mean velocity of the reaction of more than 0.5 micromole per 30 minutes

Answers

Answer:

There is not enough evidence

Explanation:

For  1.5 moles substrate concentration per liter

Reaction ( n2 ) = 15 runs

average velocity ( x2 ) = 7.5 micromoles per 30 minutes

standard deviation ( s2 ) = 1.5

For 2.0 moles substrate concentration per liter

Reaction( n1 ) = 12 runs

average velocity ( x1 ) = 8.8 micromoles per 30 minutes

standard deviation ( s1 )  = 1.2

Show Reason to believe that this increase in substrate conc causes an increase in mean velocity

Hypothesis test

H0 : μ1 - μ2 = 0.5

H1 : μ1 - μ2  > 0.5

level of significance ( ∝ ) = 0.01

attached below is a detailed solution to the problem

P-value ( 0.073 ) > level of significance ( 0.01 ) hence we fail to reject the null hypothesis

hence there in not enough evidence to believe that this increase causes an increase in the mean velocity of the reaction of more than 0.5 micromole per 30 minutes

if 5 L of butane is reacted what volume of carbon dioxide is produced ILL GIVE BRAINLIEST

Answers

Answer: First, here is the balanced reaction:  2C4H10  +  13O2  ===>  8CO2  +  10H2O.

This says for every mole of butane burned 4 moles of CO2 are produced, in other words a 2:1 ratio.

Next, let's determine how many moles of butane are burned.  This is obtained by

5.50 g / 58.1 g/mole  =  0.0947 moles butane.  As CO2 is produced in a 2:1 ratio, the # moles of CO2 produced is 2 x 0.0947  =  0.1894 moles CO2.

Now we need to figure out the volume.  This depends on the temperature and pressure of the CO2 which is not given, so we will assume standard conditions:  273 K and 1 atmosphere.

We now use the ideal gas law PV = nRT, or V =nRT/P, where n is the # of moles of CO2, T the absolute temperature, R the gas constant (0.082 L-atm/mole degree), and P the pressure in atmospheres ( 1 atm).

V = 0.1894 x 0.082 x 273.0 / 1  =  4.24 Liters.

Question:

At standard temperature and pressure, the volume of a tire is 3.5L. What is the new pressure if the temperature outside is 296k and its weight causes the volume of the gas is 2.0 L?

Answer:

The new pressure is: 1.896 atm

Explanation:

At standard temperature and pressure, we have:

[tex]P_1 = 1atm[/tex]

[tex]T_1 = 273.15k[/tex]

[tex]V_1 = 3.5L[/tex]

Outside, we have:

[tex]T_2 = 296k[/tex]

[tex]V_2 = 2.0L[/tex]

Required

Determine the new pressure

Using combined gas law, we have:

[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]

This gives:

[tex]\frac{1 * 3.5}{273.15} =\frac{P_2*2.0}{296}[/tex]

Solve for [tex]P_2[/tex]

[tex]P_2 = \frac{296 * 1 * 3.5}{273.15*2.0}[/tex]

[tex]P_2 = \frac{1036}{546.30}[/tex]

[tex]P_2 \approx 1.896 atm[/tex]
