Answer:
Royal jelly is a honey bee secretion that is used in the nutrition of larvae and adult queens.
Nuptial flight: a flight of sexually mature social insects (as bees) in which mating takes place and which is usually a prelude to the forming of a new colony; especially : the mass flight and mating of winged sexual forms of ants after leaving the parent nest.
Cocoon: a silky case spun by the larvae of many insects for protection in the pupal stage.
Group B:
Not sure) a- Keep in cold places because when there are changes in weather, it could help the silkworm come out faster.
b-They live together in a large, well organized group and bees engage in complex activities that required works from other community members in the bee society.
c- i dont know this part sorry =(
d-The larvae of a silk moth secrete the silk thread which is used to make clothes. Honey bees produce and store honey which is nutritious food. Silkworm is a creamy white colored insect which is about 2-3 cm long and shining in nature Bee larvae have been shown to be an excellent food source for rearing insects
Explanation:
Answer:
For group A
Explanation:
1. A royal jelly is a substance that is secreted by the worker honeybee's. This is fed to a potential queen bee to help them grow.
2. The nupital flight is part of reproduction for ants, termites, and most bee species.
3. A cocoon is used for the resting pupal stage in the life cycle of animals like butterflies and moths. It is a protective covering and is silky.

The saturation point for a solution is 250 grams of solute per 500 grams of solvent. If you pour 500 grams of
solute into 800. grams of solvent, how many grams of solute are in solution? 3-digit answer only
Answers
Answer: 400 g of solute is present in the solution
Explanation:
A solution consists of solute and solvent. A solute is defined as the component that is present in a smaller proportion and solvent is defined as the component that is present in a larger proportion.
Saturation point of a solution is defined as the point after which the solution becomes saturated. This simply means no more solute can be added to the solution.
Mass of solvent = 800 g
At saturation point, 500 g of solvent can dissolve 250 g of solute
Applying unitary method:
800 g of solvent will dissolve = [tex]\frac{250g}{500g}\times 800g=400g[/tex] of solute
Hence, 400 g of solute is present in the solution.

Answers
Answer:
a. True
b. True
c. True
d. False
Explanation:
At equilibrium condition, the amount of products must be equal to the amount of reactants means 50% of reactant is converted into product and 50% of product is converted into reactant. During equilibrium, the concentration of the products as well as reactant does not change. Yes, a collision between reactants is needed to initiate and complete the reaction. If the concentrations of the reactants are too large, the rate of the forward reaction will be faster than the reverse reaction, and some of the reactants will be converted into products until equilibrium is achieved.

If you have 3 moles of gas at a pressure of 2.5 atmospheres and a volume of 8 liters, what is the temperature? Pay attention to the unit of pressure used.
Answers
Answer:
-191.7°C
Explanation:
P . V = n . R . T
That's the Ideal Gases Law. It can be useful to solve the question.
We replace data:
2.5 atm . 8 L = 3 mol . 0.082 L.atm/mol.K . T°
(2.5 atm . 8 L) / (3 mol . 0.082 L.atm/mol.K) = T°
T° = 81.3 K
We convert T° from K to C°
81.3K - 273 = -191.7°C
Answer:
The temperature is 81.3 K.
Explanation:
An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:
P*V = n*R*T
where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas. The universal constant of ideal gases R has the same value for all gaseous substances.
In this case:
P= 2.5 atmV= 8 Ln=3 molesR= 0.082 [tex]\frac{atm*L}{mol*K}[/tex]T= ?Replacing:
2.5 atm* 8 L= 3 moles* 0.082 [tex]\frac{atm*L}{mol*K}[/tex] *T
Solving:
[tex]T=\frac{2.5 atm* 8 L}{3 moles* 0.082\frac{atm*L}{mol*K}}[/tex]
T= 81.3 K
The temperature is 81.3 K.

An ideal gas is contained in a cylinder with a volume of 5.0x102 mL at a temperature of 30°C and a pressure of 710. Torr. The gas is then compressed to a volume of 25 mL, and the temperature is raised to 820° C. What is the new pressure of the gas?
Answers
Answer:
51207 torr is the new pressure of the gas
Explanation:
We can solve this question using combined gas law that states:
P1V1T2 = P2V2T1
Where P is pressure, V volume and T absolute temperature of 1, initial state and 2, final state of the gas
Computing the values of the problem:
P1 = 710torr
V1 = 5.0x10²mL
T1 = 273.15 + 30°C = 303.15K
P2 = ?
V2 = 25mL
T2 = 273.15 + 820°C = 1093.15K
Replacing:
710torr*5.0x10²mL*1093.15K = P2*25mL*303.15K
3.881x10⁸torr*mL*K = P2 * 7.579x10³mL*K
P2 = 51207 torr is the new pressure of the gas

Organize the following list of elements from highest to lowest Ionization Energy:
Phosphorus, Bismuth, Arsenic, Antimony, Nitrogen
Answers
Answer: The list of elements from highest to lowest Ionization Energy is Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth.
Explanation:
The amount of energy required to remove the most loosely bound electron from an isolated gaseous atom or ion is called ionization energy.
Element with a half-filled orbital requires much more energy to remove an electron. This is because element with a half-filled electronic configuration is the most stable in nature.
More stable or tightly electrons are bound to the nucleus of an atom more will be its ionization energy. This also means that smaller is the atom higher will be its ionization energy.
When we move from top to bottom in a group the size of atom increases and the attraction between nucleus of atom and its valence electrons decreases. Hence, less will be the ionization energy.
Therefore, ionization energy decreases on moving down a group.
So, the given elements Phosphorus, Bismuth, Arsenic, Antimony, Nitrogen are all group 15 elements. Hence, decreasing order of their ionization energy is as follows.
Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth
Thus, we can conclude that the list of elements from highest to lowest Ionization Energy is Nitrogen > Phosphorus > Arsenic > Antimony > Bismuth.

Answers
Answer:

Explanation:
Using ideal gas law equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information given in the question;
n = 3 moles
V = ?
P = 105.2 KPa = 105.2/101 = 1.04atm
T = 24.0°C = 24 + 273 = 297K
Using PV = nRT
1.04 × V = 3 × 0.0821 × 297
1.04V = 73.15
V = 73.15 ÷ 1.04
V = 70.34 litres.
Explain in terms of structure and bonding why carbon dioxide has a low boiling point and calcium carbide has a high boiling point
Answers
Answer:
See explanation
Explanation:
Let us consider the two compounds carefully. Carbon dioxide is purely a non-polar molecular compound while the bond between the C2^2- ion and Ca^2+ is ionic thereby making CaC2 an ionic compound.
Recall that ionic compounds have high melting and boiling points due to strong ionic interactions in the structure of the compound.
On the other hand, CO2 is a non-polar substance whose molecules are held together only by weak dispersion forces.
As a result of the reasons outlined above, carbon dioxide has a low boiling point and calcium carbide has a high boiling point.

Answers
Answer:
15.06 L
Explanation:
Using the ideal gas law equation:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question,
P = 3.50 atm
n = 1.9 moles
V = ?
T = 65°C = 65 + 273 = 338K
Using PV = nRT
V = nRT/P
V = (1.9 × 0.0821 × 338) ÷ (3.5)
V = 52.725 ÷ 3.5
V = 15.06 L
