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.

4. They feed on mulberry leaves.

container has 3 moles of gas with a volume of 60 liters and at a temperature of 250 K, Calculate the pressure inside the container in kPa

Answers

Answer:

103.98 kpa

Explanation:

Pv= nRT

Where

P= pressure of the system=

n= number of moles= 3 moles

T= temperature= 250 K

Volume of the container= 60 liters

R= 0.0821L.atm/K.mol

Substitute the values

Pv= nRT

P= nRT/ V

= (3×0.0821×250)/60

= 1.026 Atm

1atm= 101325 Pascal

1.026 atm= X

= 103984 pasca

Convert to kilopascal

= 103984 pasca /1000

= 103.98 kpascal

112 g of aluminum carbide react with 174 g water to produce methane and aluminum hydroxide in the reaction shown below.

2 Al4C3(s) + 12 H2O(l) → 3 CH4(g) + 4 Al(OH)3(s)

If aluminum carbide is the limiting reactant, how many moles of the excess reactant are left over
a
37.3 mol
b
4.68 mol
c
7.33 mol
d
131.94 mol

Answers

Answer: 4.999 moles of excess reactant will be left over.

Explanation:

Limiting reagent is defined as the reagent which is completely consumed in the reaction and limits the formation of the product.

Excess reagent is defined as the reagent which is left behind after the completion of the reaction.

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]       .....(1)

Given mass of aluminium carbide = 112 g

Molar mass of aluminium carbide = 143.96 g/mol

Putting values in equation 1:

[tex]\text{Moles of aluminium carbide}=\frac{112g}{143.96g/mol}=0.778mol[/tex]

For the given chemical reaction:

[tex]2Al_4C_3(s)+12H_2O(l)\rightarrow 3CH_4(g)+4Al(OH)_3(s)[/tex]

By the stoichiometry of the reaction:

2 moles of aluminium carbide reacts with 12 moles of water

So, 0.778 moles of aluminium carbide will react with = [tex]\frac{12}{2}\times 0.778=4.668 mol[/tex] of water

Given mass of water = 174 g

Molar mass of water = 18 g/mol

Putting values in equation 1:

[tex]\text{Moles of water}=\frac{174g}{18g/mol}=9.667mol[/tex]

Moles of excess reactant (water) left = 9.667 - 4.668 = 4.999 moles

Hence, 4.999 moles of excess reactant will be left over.
