Answer:
An allele is dominant, it will express in a person the characteristic to which it is related. When an allele is recessive, it is less likely to express the function to which it is related. Recessive traits only occur when in a person both alleles are recessive.

6.12 moles of Na3PO4 experimentally produced 1001g of sodium chloride according to the equation below. What is the percent yield?
2Na3PO4 + 3 CaCl2 --> Ca3(PO4)2 + 6NaCl
Answer:
155.5%
Explanation:
from the equation
2mol of Na3PO4 reacts to give 6mol of Nacl
therefore 6.12mol of Na3PO4 will give 18.36mol of Nacl
2mol Na3PO4............ 6mol of nacl
6.12mol NaPO4.......... 6×6.12mol/2mol = 18.36mol of Nacl
mass of Nacl = mol × molar mass
where molar mass of Nacl= 23+12=35g/mol
mass of Nacl= 18.36 × 35= 642.6g of Nacl
percentage yield = actual yield/ theoretical yield ×100%
percentage yield= 1001g (given)/642.6g(used) ×100 = 155.5%
Answer:
107%
Explanation
6.12 mol Na3Po4 | 6 mol NaCl | 58.44 g NaCl
______________________________________ = 1072g NaCl
| 2 mol Na3Po4 | 1 mol NaCl
1072g/1001g x 100= 107%
How many moles are there in 1.27 x 10^24 atoms of potassium
Answer:
Explanation:
We know that, 1 mole of any substance contain 6.022 X 10^23 atoms/molecules.
Thus, 6.022 X 10^23 atoms = 1 mole
Therefore, 1.29x10^24 =
= 2.14
Thus, 2.14 moles are present in 1.29x10^24 hydrogen atoms in HF.
Calculate the molar concentration of a solution containing 433 grams of C6H12O6 in 82 milliliters of water. The molar mass of C6H12O6 is 180.156 g/mol
Answer:
29.27M
Explanation:
Molar concentration can be calculated using the formula;
Molar concentration (molarity) = number of moles ÷ volume
Mole = mass ÷ molar mass
Where;
Molar Mass of glucose (C6H12O6) = 180.156g/mol
Mass = 433g
Mole = 433/180.156
Mole = 2.40moles
Volume = 82mL
Since 1L = 1000mL
82mL = 82/1000
= 0.082L
Molar conc. = 2.40mol/0.082L
Molar conc. = 29.27M
which pair will for an ionic compound
Answer: A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
The chart below shows monatomic ions formed when an atom loses or gains one or more electrons, and the ionic compounds they form. You can check your periodic table to see that the cations are monatomic ions formed from metals, and the anions are monatomic ions formed from nonmetals.

How does ice make room temperature water so cold so fast? Does the water from the ice melting off when the room temp water hits the ice cube make it cold?
Answer:
ice absorbs heat from water.
Explanation:
Heat is a measure of molecular activity: the faster a thing's molecules move, the more heat that substance contains. And because everything is made of molecules, and molecules are in constant motion, everything contains at least some heat.
Because ice molecules move slowly and cluster tightly together, they produce a relatively low amount of heat. When ice is placed in a glass of water whose molecules are moving at a greater rate, the ice begins to absorb energy, because heat always travels from regions of relative warmth to colder areas in order to equalize temperatures. In other words, ice absorbs heat from the water.
As the water molecules lose energy, they begin to slow down, and consequently cool. So, it's kind of the opposite of what you might think: when we put ice in water, the ice doesn't give its cold to the water, it takes heat from the water.

3. Charles Law: What is the volume of the air in a Helium balloon that has 135 mL at 67.6 degrees
Fahrenheit if the temperature is raised to 100. degrees Fahrenheit?
Answer:
199.7mL
Explanation:
Using Charles law equation as follows:
V1/T1 = V2/T2
Where;
V1 = initial volume (mL)
T1 = initial temperature (°F)
V2 = final volume (mL)
T2 = final temperature (°F)
According to the information provided in this question, V1 = 135mL, V2 = ?, T1 = 67.6°F, T2 = 100°F
Using V1/T1 = V2/T2
135/67.6 = V2/100
Cross multiply
135 × 100 = 67.6 × V2
13500 = 67.6V2
V2 = 13500/67.6
V2 = 199.704
The new volume in the air in the helium ballon is 199.7mL.

Blackboard chalk contains a certain percentage of calcium carbonate. If a 1.51 g piece of chalk produces 0.665 g of carbon dioxide, what percentage of calcium carbonate is chalk?
The percentage of Calcium carbonate in chalk = 100%
Further explanationGiven
1.51 g piece of chalk produces 0.665 g of carbon dioxide
Required
percentage of calcium carbonate
Solution
Reaction
CaCO3 (s) + 2 HCl (aq) → CaCl2 (aq) + H2O (l) + CO2 (g)
mol CO2 :
= 0.665 g : 44 g/mol
= 0.015
From the equation, mol CaCO3 = mol CO2 = 0.015
mass CaCO3 :
= mol x MW
= 0.015 x 100
= 1.5 g

CAN SOMEONE HELP ME PLEASE Evaluate, using the measurements and observations in Figure 8, whether ethanol or butanol is the
better fuel for heating the water.
Include calculations in your answer.
Answer:
ethanol
Explanation:
The better fuel for heating the water is ethanol as it burned with a clean blue flame.
What are the different colors of flame?The color of a flame can be red, orange, blue, yellow, or white. When extra chemicals are added to the fuel burning, it affects the frequencies of visible light radiation emitted.
The temperature of a flame is shown by its color and bright blue and has a temperature of about 1670 K. The temperature will drop as the color changes from yellow to orange. The cooler flame is often red and also forms smoke. The color of the flame also depends upon the supply of oxygen gas that is required to burn.
As mentioned in the observations of the ethanol and butanol. The ethanol burns the clean blue flame while butanol burns with a yellow sooty flame.
Therefore, ethanol is a better fuel for heating water than butanol.
