Se ha añadido un evaporador para una alimentación de 11500 kg/dia de zumo de pomelo de forma que evapore 3000 kg/dia de agua por un lado y se obtenga una disolución concentrado de 50% por el otro ¿ con qué concentración porcentual inicial se deberá alimentar el zumo? (m1 = m2 + m3) (%m1 = %m2 + %m3)

Answers

Answer 1

Answer:

37 %.

Explanation:

¡Hola!

En este caso, para el problema descrito, conocemos la corriente de entrada y la de salida del agua, por lo que podemos obtener el flujo de la corriente que contiene el zumo a la salida una vez el agua fue evaporada:

[tex]F_{sol}=11500kg/dia-3000kg/dia=8500 kg/dia[/tex]

Luego, por medio de un balance de zumo de limón en el evaporador en el cual la cantidad que entra es igual a la que sale con sus respectivas concentraciones:

[tex]x_z^{entra}*11500kg/dia=x_z^{sale}*8500kg/dia[/tex]

Como la concentración del zumo a la salida es del 50 % (0.50), la de entrada es:

[tex]x_z^{entra}=\frac{x_z^{sale}*8500kg/dia}{11500kg/dia} =\frac{0.50*8500kg/dia}{11500 kg/dia}\\ \\x_z^{entra}=0.37[/tex]

Que es igual al 37%.

¡Saludos!

A piece of metal of mass 27 g at 93° C is placed
in a calorimeter containing 59.2 g of water at
21°C. The final temperature of the mixture is 34.9 ° C. What is the specific heat capacity of the metal? Assume that there is no energy lost to the surroundings.
Answer in units of J/g. ° C

Answers

Answer:

1.586 J/g°C

Explanation:

So, we have the formula [tex]q = mc\Delta t[/tex].

Since heat released by the metal is = to the heat absorbed by the water (because they eventually become the same temperature in solution), we can say

[tex]m_{water}C_{water}(T_{water}-T_f) = - m_{metal}C_{metal}(T_{metal} - T_f)[/tex]

Plugging in, we get:

[tex]59.2*4.184*(21- 34.9) = - 27*C_{metal}*(93 - 34.9)[/tex]

Solving, we get [tex]C_{metal} = 1.586[/tex] J/g°C.

sweeten soft drinks, is one of the causes of childhood obesity. In a recent study, at the

University of Cincinnati, researchers found that mice that drank water with added

fructose ate less solid food, gained more weight, and put on 90% more body fat than

mice that drank only water. Scientists concluded that fructose may affect metabolism in

a way that favors fat storage.

Answer:

Explanation:

The independent variable in an experiment is the type of variable which is changed at intervals in order to study if it has a direct effect on the dependent variable.

The dependent variable in the experiment is the amount of weight gained by the mice in each group and the control group is the mice who drank the water without the fructose added.

If I have 12 protons, how many neutrons and electrons would I need to make a stable atom?

Answers

Answer:

im pretty sure you need 15 in all but dont get mad it thats wrong, so you would i think need 3 neutrons

Explanation:

In an atom, there are 12 electrons and protons while the number of neutrons is 6.

What is an atom?

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

At 9°C a gas has a volume of 6.17 L. What is its volume when the gas is at standard temperature?

Answers

Answer:

V₂ = 5.97 L

Explanation:

Given data:

Initial temperature = 9°C (9+273 = 282 K)

Initial volume of gas  = 6.17 L

Final volume of gas = ?

Final temperature = standard = 273 K

Solution:

Formula:

The Charles Law will be apply to solve the given problem.

According to this law, 'the volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure'

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 6.17 L ×  273K /  282  k

V₂ = 1684.41 L.K / 282 K

V₂ = 5.97 L

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.  2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product  3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

For gas combustion reaction which is a reaction of hydrocarbons with oxygen produces CO₂ and H₂O (water vapor). can use steps:  

Balancing C atoms, H and the last O atoms

Reaction

Zn + HNO₃⇒ Zn(NO₃)₂ + NO + H₂O

1. gives a coefficient

aZn + bHNO₃⇒ Zn(NO₃)₂ + cNO + dH₂O

2. make an equation

Zn : left = a, right =1 ⇒a=1

H : left = b, right = 2d⇒ b=2d (eq 1)

N : left = b, right = 2+c⇒b=2+c (eq 2)

O : left = 3b, right = 6+c+d ⇒3b=6+c+d(eq 3)

From eq 1 and eq 3

3(2d)=6+c+d

6d=6+c+d

5d=6+c (eq 4)

From eq 2 and eq 3

3(2+c)=6+c+d

6+3c=6+c+d

2c=d (eq 5)

From eq 4 and eq 5

5(2c)=6+c

10c=6+c

9c=6

c = 2/3

input eq 5

d = 2 x 2/3

d = 4/3

input eq 1

b = 2 x 4/3

b = 8/3

The equation

aZn + bHNO₃⇒ Zn(NO₃)₂ + cNO + dH₂O to

Zn + 8/3HNO₃⇒ Zn(NO₃)₂ + 2/3NO + 4/3H₂O x 3

3Zn + 8HNO₃⇒ 3Zn(NO₃)₂ + 2NO + 4H₂O

Water molecules are polar because the
water molecule has a linear shape.
water molecule has a bent shape.

Answers

Answer: B (water molecule has a bent shape)

Explanation:

Water molecules are polar molecules because of their shape. Water molecules have one side that is positively charged due to hydrogen atom which is partially positive and the other side which is negatively charged, due to the oxygen atom.

When two molecules get close to each other the polar forces of attraction brings them close to each other. Oxygen bonds with several hydrogen atoms in the other water molecules resulting to hydrogen bonds.

How does the valence electron configuration (entire last energy level configuration) relate to the group number on the Periodic Table? Use the shorthand notation in your discussion.

Answers

Answer:

The valence electron configuration determines the group to which an element belongs to.

Explanation:

The valence electron configuration of an atom of an element refers to the number of electrons in that atoms outermost shell.

The valence electron configuration is related to the group number of an element in that the number of electrons in the valence shell of an atom of an element determines the group to which an element belongs to. For example, all elements having one valence electron belong to group IA of the periodic table. Similarly, all elements having seven valence electrons belong to group VIIA of the periodic table.

This is because, since the reactivity of an element is related to its ability to either gain or lose a certain number of electrons in its valence shell, elements having same number of valence electrons have similar chemical properties.

Explanation:

The density, which is the mass per unit volume of an object, can be calculated using the formula;

D= m/v

Where; D = density (g/mL)

M = mass of substance (g)

V = volume (mL)

In this question, the object's mass = 15g, volume of water= 2.5 mL, d =?

Therefore,

Density = 15/2.5

Density = 6 g/mL

The object's density is 6g/mL

You have a solution of water and pure ethanol. The boiling point of water is 100 degrees Celsius and the boiling point of pure ethanol is 78 degrees Celsius. A. What process would you would use to separate this solution? Describe, in detail, how this process works.

Answers

Answer:

Distillation

Explanation:

A solution of water and ethanol are miscible. Hence, they can only be separated by a process known as distillation. Distillation is the process in which two or more constituents in a mixture are separated based on there difference in boiling points. The mixture is subjected to high heat and the one with the least boiling point distills/evaporates out first followed by the next least boiling point.

From the explanation above, it can be deduced that ethanol (with boiling point of 78°) will be distilled out while water remains in the boiling tube or container.
