D- The crust is extrememly thin when compared to the core of mantle

Answer:

The answer Is the polar solvent molecule surrounds the positive sodium ions and the negative chloride ions.

The highly polar molecule covers the positive ions of sodium as well as the negatives chloride ions whenever salt dissolves in water.

The ability of a material, the solute, to combine with that other substance, the solvent, is known as solubility in chemistry. Insolubility, or the solute's inability to create such a solution, is the opposite attribute. The concentration of both the solute inside a saturated solution—a solution whereby no more solute could be dissolved—is typically used to gauge the degree of a substance's solubility in a particular solvent.

For some solutes as well as solvents, there might not be any such limit, in whose case these two substances are referred to as "miscible in any quantities". The highly polar molecule covers the positive ions of sodium as well as the negatives chloride ions whenever salt dissolves in water.

Therefore, the highly polar molecule covers the positive ions of sodium as well as the negatives chloride ions whenever salt dissolves in water.

Answer: pizza crust, Vegetables, Dairy, Meat, and Dairy

Explanation:

The pizza crust is important, not only to deliver those mouthwatering toppings to your anxiously waiting taste buds, but to provide vital nutrients from grains. Vegetables are a common and delicious topping for pizza. These toppings provide an array of nutrients and including multiple servings of vegetables in your diet every day is a necessary part of a healthy lifestyle. If you get meat on your pizza, it is an excellent source of protein. All meat is high in protein and iron, which are necessary to build muscle. Cheese is a good source of the calcium we all need for strong bones and teeth. Cheese is also a good source of protein.

A bread crust contains carbohydrate, vegetables contains vitamins, cheese contain calcium and protein, meat contain protein.

Nutrients are the substance that makes a body healthy.

Food material contain different nutrients that help in growth of the body.

In pizza, we get all type of nutrients

A bread crust contains carbohydrate which provide energy.

Vegetable contains vitamins to keep the body parts healthy.

Cheese contain calcium and protein which maintain the growth and repairing of the body.

Meat contain protein, good for muscles.

Thus, A bread crust contains carbohydrate, vegetables contains vitamins, cheese contain calcium and protein, meat contain protein.

See Explanation

Explanation:

                     8Fe        +        S₈                =>        8FeS

Given:            10g                  10g

moles      10g/56g/mol     10g/256g/mol

                = 0.179mol Fe   = 0.039mol S₈

Reduce => divide mole values by respective coefficients; smaller value is Limiting Reactant.

                 0.179/8 = 0.022      0.039/1 = 0.039  

       => Fe is limiting reactant

                       8Fe        +               S₈                   =>         8FeS    

Given:     10g/56g/mol          10g/256g/mol

               = 0.179mol              = 0.039 mol                  0.179mol FeS produced

                                          1/8(0.179)mol S₈ used        (coefficients are equal,

                                          = 0.022 mol S₈ used       => moles Fe = moles FeS)

                                         = (0.039 - 0.022)mol S₈     = 0.179mol FeS

                                         remains in excess              =(0.179mol)(88g/mol)

                                         = 0.0166 mol S₈ (excess)  = 15.8 g FeS  

                                         = (0.0166mol)(256g/mol)           (Theoretical Yield)

                                         = 4.26g S₈ in excess

Answer:

See Explanations

Explanation:

The Empirical Gas Laws include ...

Boyles Law => P₁V₁ = P₂V₂

Charles Law => T₁/V₁ = T₂/V₂

Gay-Lussac's Law => P₁/T₁= P₂/T₂

Avogadro's Law => V₁/n₁ = V₂/n₂

Combined Gas Law => P₁V₁/T₁ = P₂V₂/T₂

Ideal Gas Law => PV = nRT; R = 0.08206 L·Atm/mol·K

One only needs to learn the 'Combined Gas Law' in that it embodies all of the gas law problems.

Start with a simple table for P, V & T and enter given data. If a variable is not given, assume it is constant. Set up P₁V₁/n₁T₁ = P₂V₂/n₂T₂ and substitute given data. Solve for unknown.

Your Problems:

1. P₁ = 1 Atm        P₂ = 3 Atm

  V₁ = 300ml      V₂ = ?

  T₁ = Constant  T₂ = T₁

   n₁ = Constant  n₂ = n₁

P₁V₁/n₁T₁ = P₂V₂/n₂T₂  

=> (1Atm)(300ml)/(Constant)(Constant) = (3Atm)(V₂)/(Constant)(Constant)

=> (1Atm)(300ml) = (3Atm)V₂

=> V₂ = (1Atm)(300ml)/(3Atm) = 100ml

2. P₁ = 1 Atm        P₂ = ?

   V₁ = Constant  V₂ = V₁

   T₁ = 273K         T₂ = 82K

   n₁ = Constant  n₂ = n₁

P₁V₁/n₁T₁ = P₂V₂/n₂T₂

=> (1Atm)(Constant)/(273K)(Constant) = (P₂)(Constant)/(82K)(Constant)

=> (1Atm)/(273K) = (P₂)/(82K)

=> P₂ = (1Atm)(82K)/(273K)

=> P₂ = 0.3 Atm (1 sig-fig)

3. P₁ = 101.25kPa     P₂ = 506kPa

   V₁ = 5 Liters         V₂ = ?

   T₁ = Constant       T₂ = T₁

   n₁ = Constant  n₂ = n₁

P₁V₁/n₁T₁ = P₂V₂/n₂T₂

=> (101.25kPa)(5L)/(Constant)(Constant) = (506kPa)(V₂)/(Constant)(Constant)

=> (101.25kPa)(5L) =  (506kPa)(V₂)

=> V₂ = (101.25kPa)(5L)/(506kPa)

=> V₂ = 1.00 Liter

4. P₁ = Constant       P₂ = P₁

   V₁ = 3.2 Liters      V₂ = ?

   T₁ = 273°C + 273 = 546K       T₂ = 400°C + 273 =673K*

   n₁ = Constant  n₂ = n₁

*Note => be sure to convert all temps to Kelvin when working empirical gas law problems. K = °C + 273

P₁V₁/n₁T₁ = P₂V₂/n₂T₂

=> (Constant)(3.2L)/(Constant)(546K) = (Constant)(V₂)/(Constant)(673K)

=> (3.2L)/(546K) = (V₂)/(673K)

=> V₂ = (3.2L)(673K)/(546K)

=> V₂ = 3.944 Liters ≅ 3.9 Liters (2 sig-figs)

Answer:

62.15 m (squared)

Explanation:

We know that the Area of the square is 5.5 x 4= 22

so 90 degree to 30 degree is divide by 3

so u divide 22 by 3 and get 7.3 wich is the semi circle thing

now 7.3 x 5.5 = 40.15

22 + 40.15 = 62.15 m (squared)
