which substance will evaporate first???????????????????

Answer:

Hh

Explanation:

if you have a dominant allele and a recessive allele they'd be different (heterozygous)

If H represents the dominant allele and h represents the recessive allele, Hh is the genotypes of the parents shown in the pedigree.

The type of variation present at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolize it. For illustration, BB, Bb, and bb might be employed to denote a certain gene variant.

The actual DNA sequence, such as CC, CT, or TT, can also serve as a representation of a genotype. In a single experiment, the genotypes spanning millions of sites in a genome can be determined using DNA sequencing as well as other techniques. If H represents the dominant allele and h represents the recessive allele, Hh is the  genotypes of the parents shown in the pedigree.

Therefore,  Hh is the  genotypes of the parents shown in the pedigree.

Explanation:

How many grams of KCl will dissolve in 1 liter of H2O at 50 °C? 5. 58.0 g of K2Cr2O7 is added to 100 g H2O at. 0 °C. With constant stirring, to what temp-.

The percentage yield of the reaction has been 46.74%.

Percentage yield can be given as the ratio of the actual yield to the theoretical yield.

For the theoretical yield, the balanced equation will be:

[tex]\rm 2\;ZnS\;+\;3\;O_2\;\rightarrow\;2\;ZnO\;+\;2\;SO_2[/tex]

Thus, 2 moles of ZnS will give 2 moles of ZnO.

The moles of 46.5 g ZnS:

Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]

ZnS = [tex]\rm \dfrac{46.5}{97.474}[/tex]

ZnS = 0.477 mol

The moles of 13.3 grams Oxygen:

Oxygen = [tex]\rm \dfrac{13.3}{32}[/tex]

Oxygen = 0.415 mol.

The moles of 18.14 grams ZnO:

ZnO = [tex]\rm \dfrac{18.14}{81.38}[/tex]

ZnO = 0.222 mol

According to the balanced chemical equation,

2 moles ZnO = 2 moles ZnS

0.222 mol ZnO = 0.222 mol ZnS

2 moles ZnO = 3 moles Oxygen

0.222 mol ZnO = 0.334 mol of Oxygen

Since, both the reactants are in enough concentration,

The theoretical yield can be calculated with any of the reactants. The theoretical yield of ZnO from 46.5 grams of ZnS can be given as:

1 mole ZnS = 1 mol ZnO

0.477 mol of ZnS = 0.477 mol of ZnO.

The mass of 0.477 mol of ZnO:

Mass = moles [tex]\times[/tex] molecular weight

Mass of ZnO = 0.477 [tex]\times[/tex] 81.38

Mass of ZnO = 38.818 grams.

The theoretical yield of ZnO = 38.818 g.

The actual yield of ZnO = 18.14 g.

Percentage yield = [tex]\rm \dfrac{18.14}{38.81}\;\times\;100[/tex]

Percentage yield = 46.74 %

The percentage yield of the reaction has been 46.74%.

Answer:

Zr(Cr2O7)2

Explanation:

Answer: 25.13 g of [tex]N_2O[/tex]  and 20.56 g of [tex]H_2O[/tex] will be produced from 45.70 g of [tex]NH_4NO_3[/tex]

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} NH_4NO_3=\frac{45.70g}{80.04g/mol}=0.571moles[/tex]

The balanced chemical equation is:

[tex]NH_4NO_3\rightarrow N_2O+2H_2O[/tex]  

According to stoichiometry :

1 mole of [tex]NH_4NO_3[/tex] produce = 1 mole of [tex]N_2O[/tex]

Thus 0.571 moles of [tex]NH_4NO_3[/tex] will require=[tex]\frac{1}{1}\times 0.571=0.571moles[/tex]  of [tex]N_2O[/tex]  

Mass of [tex]N_2O=moles\times {\text {Molar mass}}=0.571moles\times 44.01g/mol=25.13g[/tex]

1 mole of [tex]NH_4NO_3[/tex] produce = 2 moles of [tex]H_2O[/tex]

Thus 0.571 moles of [tex]NH_4NO_3[/tex] will require=[tex]\frac{2}{1}\times 0.571=1.142moles[/tex]  of [tex]H_2O[/tex]  

Mass of [tex]H_2O=moles\times {\text {Molar mass}}=1.142moles\times 18g/mol=20.56g[/tex]

Thus 25.13 g of [tex]N_2O[/tex]  and 20.56 g of [tex]H_2O[/tex] will be produced from 45.70 g of [tex]NH_4NO_3[/tex]

Answer:

The specific heat of water is more specific than the heat of sand, therefore, it will take more energy to raise the same amount of water with the same temperature.

Explanation:

The temp is 89 F so, 31.67° C

The specific heat of  the water is 4.184 J/g° C

The specific heat of the sand is 0.290 J/ g° C

The heat is the amount  of energy that is needed to raise the temp. of the substance

You will need a lot more energy to raise the temp of the water then of the same amount of sand, therefore, because of the specific lower heat of the sand it will raise it's temperature quicker compared to water.

Explanation:

nun

Answer:

Both the pebble and metal bead of the same mass will be equally accelerated  if they are at the same place, in this case, they are in the same place meaning they will be accelerated at the same speed towards the earth. Thus even if they are in the water they will sink at the same speed and finally will reach the bottom of the cup.

Answer:

The OH would be .7825 and the basic solution is a strong base.

Explanation:

What you would do is -log(0.165) in your calculator which would give you 0.7825160065 as an answer. Im not sure what the significant figure is so I will not be rounding to that, but that is your answer for the first part.

The second part: because your pOH is a .7825, this would be consiered a strong base in the pOH because it is closer to 1 which is your base.
