Answer:

2 significant figures i.e. 2 and 7.

Explanation:

We need to find the number of significant figures in the given number i.e. [tex]2.7\cdot10^{-3}[/tex].

It has 2 significant figures i.e. 2 and 7.

It means the power of 10 doesn't count in the significant figures.

Hence, there are 2 significant figures.

Answer:

98.4 kPa

Explanation:

Step 1: Given and required data

Step 2: Calculate the total pressure of the gaseous mixture

The total pressure of the gaseous mixture (P) os equal to the sum of the partial pressures of the gases that form it.

P = pH₂O + pN₂ + pHe

P = 19.9 kPa + 53.0 kPa + 25.5 kPa = 98.4 kPa

The total pressure of the wet gas mixture is 98.4 KPa

This law states that at constant temperature, the total pressure of a mixture of gases is equal to the sum of the partial pressure exerted by each gas. Mathematically, it is expressed as

Total pressure = partial pressure of A + partial pressure of B

P = pH₂O + pN₂ + pHe

P = 19.9 + 53 + 25.5

P = 98.4 KPa

Answer:

[OH-] = 2 x 10^-6 M

Explanation:

Calculate pOH first: 14 - pH = pOH --> pH = 14 - 8.3 = 5.7

[OH-] = 10^-pOH = 10^-5.7 = 2 x 10^-6 M

Only one sig fig in the concentration, because the pH only had one decimal place.

Answer: 35.6 g/mol

Explanation: I guessed and got it correct

The molar volume of any gas behaving ideally at STP is 22.414 L. The molar mass of the gas at STP is 35.59 g.

The molar mass of a substance is defined as the mass of one mole of molecules. In other words one gram molecular mass of a substance is same to its molar mass in g mol⁻¹.

The molar mass of a substance can be obtained by adding the atomic masses of each elements.  At 0°C and 1 atm, 1 mole of any gas behaving ideally occupies a volume of 22.414 L.

Here 5.00 L of the gas at STP has a mass of 7.94. Then the molar mass of 22.414 liters of the gas can be calculated as:

7.94 × 22.414/5.00 = 35.59 g.

Thus the molar mass of the gas is 35.59 g.

Answer:

3.7 L

Explanation:

Initial volume (V₁) = 3.3 L

Initial pressure (P₁) = 100 KPa

Final pressure (P₂) = 90 KPa

Final volume (V₂) =?

The final volume of the gas can be obtained by using the Boyle's law equation as follow:

P₁V₁ = P₂V₂

100 × 3.3 = 90 × V₂

330 = 90 × V₂

Divide both side by 90

V₂ = 330 / 90

V₂ = 3.7 L

Thus, the final volume of the gas is 3.7 L

Answer: The partial pressure of the dry gas is 599.8 torr

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

[tex]p_{total}=p_{dry gas}+p_{H_2O}[/tex]

Given : [tex]p_{total}[/tex] =total pressure of gases = 642 torr

[tex]p_{dry gas}[/tex] = partial pressure of dry gas = ?

[tex]p_{H_2O}[/tex] = partial pressure of water = 42.2 torr

putting in the values we get:

[tex]642torr=p_{\text {dry gas}}+42.2torr[/tex]  

[tex]p_{\text {dry gas}}=599.8torr[/tex]

Thus the partial pressure of the dry gas is 599.8 torr

Answer:

13.50 moles of AgNO₃ are needed to produce 6.75 moles of Cu(NO₃)₂

Explanation:

We state the reactants:

AgNO₃

Cu

Then, the products are:

Cu(NO₃)₂

Ag

The reaction is:  2AgNO₃ + Cu  → 2Ag + Cu(NO₃)₂

Ratio is 1:2.

The copper is in excess, so the limiting reactant is the silver nitrate:

1 mol of Cu(NO₃)₂ is produced by 2 moles of AgNO₃

Then, 6.75 moles of copper (II) nitrate would be produced by, the double of moles

(6 75  . 2) /1  = 13.50 moles

Answer:

Genotypic ratio = 1 Bb: 1 bb

Phenotypic ratio = 1 black rabbit : 1 brown rabbit

Explanation:

This question involves a gene coding for hair color in rabbits. The allele for Black hair (B) is dominant to the allele for brown hair (b).

According to this question, a black rabbit whose mother is brown haired (bb) is crossed with a brown hair rabbit. This means that the black rabbit will have a genotype 'Bb' while the brown rabbit will have a genotype 'bb'. Each parent will produce the following gametes:

Bb - B and b

bb - b and b

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Bb, Bb, bb and bb

This means that the;

Genotypic ratio = 1 Bb: 1 bb

Phenotypic ratio = 1 black rabbit : 1 brown rabbit

Answer:

Scientists develop knowledge by making observation about the natural world that may lead to a scientific question.

A scientific question may lead to a(n) hypothesis which can be tested.

The results of experimentation can lead to changes in scientific knowledge.

Explanation:

In the process of developing scientific knowledge, scientists carry out series of observations on what happens in the natural world. This helps them to develop scientific questions. These scientific questions drawn can then lead to hypotheses which are testable.

The testing process leads to experimentation. It is in this process that much scientific questions receive answers. Testing actually lies at the core of scientific inquiry for all scientists. Whatever hypothesis made must always be tested.

The result of the testing or experimentation brings changes in scientific knowledge.

Explanation:

Sexual reproduction results from the fusion of gametes produced by male and female. Sexual reproduction causes more viable variations because:

→ There might be an error in the copying of DNA, though the event is rare.

→ Segregation of chromosome of maternal and paternal origin at the time of gamete formation is random.

→ There is an exchange of genetic material between homologous chromosomes during formation of gametes.

In case of asexual reproduction, variation is significantly less since only a single parent is involved. Very small changes occur due to inaccuracies during DNA copying that pass on to the progeny. Thus, offsprings of asexual reproduction are more or less genetically similar to their parents. So, it can be concluded that evolution in sexually reproducing organisms proceeds at a faster pace than in asexually reproducing organisms.

The structure and function of chromosomes convey a particular sequence, so any variation in biological reproducing organisms produce a different sequence from chromosomes.

In our body 23 pairs of chromosomes are present and 23rd pair is known as the biological chromosome as it is responsible for the gender of new offspring.

Chromosomes are present in the DNA structure and helps in the transfer of genetic material. As we know that in biological reproduction, male and female both are involved and minor change in the sequence of process creates variation in biological reproducing organisms. Like during the meiosis some changes in the cross over process, dynamic union of gametes from male organism, independent assortment during fertilization and many more explains the variation in biological reproducing organisms.

Hence, as chromosomes carry particular sequence so any variation is determined by its structure.
