Answer:

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. Often, it is impossible to determine which two alleles of a gene are present within an organism's chromosomes based solely on the outward appearance of that organism. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.

Glucose is polar and carbon tetrachloride is non polar so  it is the incorrect pair.

Water (H₂O) is the most appropriate solvent to dissolve sodium chloride (ionic). This is because sodium chloride is an ionic compound and water is a polar solvent, which means it can dissolve ionic compounds.

Acetone, methanol, ethanol, hexane, diethyl ether, toluene, and carbon tetrachloride are all non-polar solvents and are not suitable for dissolving ionic compounds like sodium chloride.

In fact, some of these solvents, like hexane and toluene, are not even soluble in water. So, to dissolve sodium chloride, it is recommended to use water as a solvent.

However, it's important to note that the solubility of sodium chloride in water decreases as the temperature decreases. At room temperature, approximately 36 grams of sodium chloride can be dissolved in 100 mL of water.

Answer:

0.241 M

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

HBr + NaOH —> NaBr + H₂O

From the balanced equation above,

The mole ratio of acid, HBr (nₐ) = 1

The mole ratio of base, NaOH (n₆) = 1

Finally, we shall determine the concentration of the NaOH solution. This can be obtained as follow:

Volume of base, NaOH (V₆) = 20 mL

Volume of acid, HBr (Vₐ) = 24.1 mL

Concentration of acid, HBr (Cₐ) = 0.2 M

Concentration of base, NaOH (C₆) =?

CₐVₐ / C₆V₆ = nₐ/n₆

0.2 × 24.1 / C₆ × 20 = 1/1

4.82 / C₆ × 20 = 1

Cross multiply

C₆ × 20 = 4.82

Divide both side by 20

C₆ = 4.82 / 20

C₆ = 0.241 M

Therefore, the concentration of the NaOH solution is 0.241 M

First, we need to determine the number of moles of hydroiodic acid in 100mL of 8.5M solution. Therefore, 1.98 g of calcium iodide forms in the reaction.

8.5 moles/L x 0.100 L = 0.85 moles of hydroiodic acid

Next, we need to determine the number of moles of calcium hydroxide used in the reaction.

0.500 g Ca(OH)2 x (1 mol Ca(OH)2/74.09 g) = 0.00674 moles Ca(OH)2

Since the stoichiometry of the reaction is 1:2 between Ca(OH)2 and HI, we need twice as many moles of hydroiodic acid to completely react with all the Ca(OH)2.

0.00674 moles Ca(OH)2 x 2 = 0.0135 moles HI needed

Since we have 0.85 moles of HI, which is more than enough to react with 0.0135 moles of Ca(OH)2, the reaction is complete.

To determine how much salt (calcium iodide) forms, we need to use the stoichiometry of the reaction, which is:

Ca(OH)2 + 2HI ⇒ CaI2 + 2H2O

Since two moles of hydroiodic acid react with one mole of calcium hydroxide to form one mole of calcium iodide, the amount of salt formed is:

0.00674 moles Ca(OH)2 x (1 mol CaI2/1 mol Ca(OH)2) = 0.00674 moles CaI2

Finally, we can calculate the mass of calcium iodide formed using its molar mass:

0.00674 moles CaI2 x 293.88 g/mol = 1.98 g CaI2

The right response is d. Both enzymes will have the same ΔG for catalysis.

The reaction rate and equilibrium constant have an impact on the Gibbs free energy (ΔG). No matter the source of the enzyme, such as E. coli or a thermophilic microbe, the ΔG for a reaction is the same. As a result, both enzymes will have the same ΔG for sucrose hydrolysis.

The ΔG may be written mathematically as:

ΔG = -RT ln (K)

T is the temperature, K is the equilibrium constant, and R is the gas constant..

As both enzymes have the same reaction rate (K) and temperature (T), the reaction's ΔG  value will likewise be the same.

Answer: Aluminum Carbonate

Explanation:

Answer:

Aluminum carbonate.

Explanation:

It is an aluminum salt form of carbonic acid.

Answer:

It depends.

Explanation:

Hot water will evaporate all on its own.  In fact, cold water will also evaporate.  It depends on how much water is already in the gas above (i.e., the humidity).  If the humidity is 100%, then liquid water is in equilibrium with the gas above it.  Water molecules will evaporate at the same rate they condense.  Even at cooler temperatures, there is still enough energy in water for one of the molecules to occasionally get bounced out of the container into the air.

I wonder if you may be asking about the boiling point of water.  At 100 degrees C, water boils (212 degrees F).  These numbers assume 1 atmosphere pressure and on the Earth's surface.  As the elevation increases, the boiling point of water decreases.  The slight reduction in gravitational pull allows more molecules to escape in the the air.

If you are asking what temperature does water have to be to form steam, that also depends on the temperature and humidity of the airspace.

Percentage of hydrogen = 20.0 %

Percentage of carbon = 80.0 %

Molar mass = 30.0 g  

Empirical formula = ?

Solution:

Number of gram atoms of H = 20 / 1.01 = 19.8  

Number of gram atoms of C = 80 /12 = 6.7

Atomic ratio:

            C              :           H            

         6.7/6.7        :        19.8/6.7  

            1               :           3        

C : H = 1 : 3

Empirical formula is CH₃.

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula = CH₃ = 12×1 +3×1.01 = 15.03 g/mol

n = 30 g/mol / 15.03 g/mol

n = 2

Molecular formula = n (empirical formula)

Molecular formula = 2 (CH₃)

Answer:

Energy from different sources leads to different types of rocks.

Explanation: Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into different types of rock.

Rocks are formed in earth by the deposition of minerals and decomposition of massive tectonic plates by the hot magma which is melted by the heat energy radiated from sun.

There are broadly three different types of rocks, namely sedimentary rocks, igneous rocks and metamorphic rocks . They are classified based on their formation and composition.

The magma that the molten mineral fluid inside the earth crest melts under heat radiated from sun and this hotter fluid flows results in movement of tectonic plates and decomposition at some places.

Therefore, the heat energy and resultant convection current leads the tectonic plate boundaries and formation of different kinds of rocks which are stimulated by the action of air and water.

Explanation:

Wood being burned up to the point it turns into ashes is a chemical change of when wood is in the presence heat. No, the ashes will not be as heavy as they used to.

The concentration of the NaOH solution is 10.00 g/dm³.

To calculate the concentration in g/dm³ of a solution of NaOH containing 0.25 moles in 1 dm³, we need to know the molar mass of NaOH.

The molar mass of NaOH is calculated as follows:

Na (Sodium) = 22.99 g/mol

O (Oxygen) = 16.00 g/mol

H (Hydrogen) = 1.01 g/mol

Molar mass of NaOH = 22.99 g/mol + 16.00 g/mol + 1.01 g/mol = 40.00 g/mol

Now, we can calculate the concentration (C) using the formula:

C = (moles of solute) / (volume of solution in dm³)

C = 0.25 moles / 1 dm³

C = 0.25 mol/dm³

To convert moles to grams, we can multiply the molar mass by the number of moles:

Concentration in g/dm³ = (0.25 mol/dm³) * (40.00 g/mol)

Concentration in g/dm³ = 10.00 g/dm³
