Answer:

950mL

Explanation:

The following were Data were obtained from the question:

Initial volume (V1) = 100mL

Initial pressure (P1) = stp = 760mmHg

Final pressure (P2) = 80mmHg

Final volume (V2) =..?

The final volume of the gas can be obtained by using the Boyle's law equation as follow:

P1V1 = P2V2

760 x 100 = 80 x V2

Divide both side by 80

V2 = (760 x 100) /80

V2 = 950mL

Therefore, the new volume of the gas is 950mL

The largest risks while designing a model to withstand a village include that the model does not mitigate the effects of the tsunami or only mitigates the effects partially, which would cause damages to the homes.

Designing a model to withstand the effect of any natural phenomenon such as an earthquake, fire or tsunami is not an easy task and will require the following cycle:

  • Designing the model.
  • Testing the model.
  • Making changes or designing a new model.

In the case of a model for tsunamis, it is likely the following problems occur:

  • The model does not protect the houses from tsunamis.
  • The model does not protect the houses completely.

This would lead to negative effects such as:

  • Damages in the houses.
  • Dead or injured people.
  • Destruction of infrastrcture.

Note: This question is incomplete because the context is missing; here is the missing part.

A cupcake recipe designed to produce 18 cupcakes calls for 260 grams of
Vedmedyk [2.9K]

Answer:

317.7778 g

Explanation:

Given data:

Flour required for 18 cup cakes = 260 g

Flour required for 22 cup cakes = ?

Solution:

We will calculate the flour required for 1 cup cake.

260 g /18   = 14.4444 g

Fluor required for 22 cupcakes,

22× 14.4444 g = 317.7778 g

In short,

22 cupcake/18 cup cake×260 g = 317.7778 g

Cu + 2 AgNO3 + Cu(NO3)2 + 2Ag
Allushta [10]

Answer:

7.28 moles Ag°

Explanation:

              Cu°          +    2 AgNO₃  => Cu(NO₃)₂ + 2Ag°

Given 7.28 moles     7.28 moles

To determine limiting reactant, divide the mole values by the respective coefficient of balanced equation. The resulting smallest value is the limiting reactant. Note: this is a short cut method for determining limiting reactant only. Once the limiting reactant is determined one must use the given mole values of the limiting reactant to solve problem. That is ...

Limiting reactant determination:

              Cu°          +    2 AgNO₃  => Cu(NO₃)₂ + 2Ag°

Cu: 7.28 / 1  = 7.28

AgNO₃ : 7.28 / 2 = 3.64 => Limiting Reactant is AgNO₃

Solving Problem depends on AgNO₃; Cu will be in excess.

Since coefficients of AgNO₃ & Ag° are equal, then the moles AgNO₃ used equals moles Ag° produced and is therefore 7.28 moles Ag°.
