Answer:

1.32m es la concentración de NaCl en el agua de mar

Explanation:

La disminución de presión de vapor sigue la ecuación:

P = XP⁰

Donde P es la presión de la solución = 23.99mmHg

X es la fracción molar del solvente

P⁰ la presión del agua pura = 24.56mmhg

23.99mmHg = X*24.56mmhg

0.97679 = X

La fracción molar del solvente se define como:

Moles Solvente / (Moles soluto + Moles solvente)

Asumiendo que las moles de soluto = NaCl = 1:

0.97679 = Moles solvente / (1 + Moles solvente)

0.97679 + 0.97679 Moles solvente = Moles solvente

0.97679 = 0.02321 moles solvente

42 moles solvente = 42 moles de agua.

masa de agua:

42 moles * (18.01g / mol) =758g de agua = 0.758kg

Molalidad, m, son las moles de soluto (1mol NaCl) por kg de solvente (0.758kg):

1mol / 0.758kg =

Answer: potassium and rubidium

Explanation:

1) The group 1 of the periodic table contain six elements namely Lithium(Li), Sodium(Na),Potassium(K),Rubidium(Rb),Cesium(Cs) and Francium(Fr). These metals are called alkali metals because they form alkalies( i.e. strong bases capable of neutralizing acids) when they react with water.

2) The heavier alkali metals (K, Rb, and Cs) react so vigorously that they invariably explode.

3) This trend, which is not consistent with the relative magnitudes of the reduction potentials of the elements, serves as another example of the complex interplay of different forces and phenomena—in this case, kinetics and thermodynamics.

Answer:

you're going to start by balancing the carbon first. To do this, you want to times the carbon on the right by 4 so we put a 4 in front of the CO2.C4H8 + O2 --> 4CO2 + H2OWe're now going to try and balance the hydrogen by putting a 4 in front of the H2O.C4H8 + O2 --> 4CO2 +4H2OThen we're going to count the oxygens on both side and balance them by putting a 6 in front of the O2.C4H8 + 6O2 --> 4CO2 + 4H2O

Answer:

hope this helps :) please correct me if I'm wrong.

C4H8 + 6O2 --> 4CO2 + 4H2O.

Explanation:

C4H8 + O2 --> CO2 + H2O

C=4 C=1

H=8 H=1

O=2 ---> O=3

C4H8 + 6O2 --> 4CO2 + 4H2O

C=4 C=4

H=8 H=8

O=12 ---> O=12

Answer: The volume of the balloon up there is 6.192 L.

Explanation:

Given: [tex]V_{1}[/tex] = 1.80 L,    [tex]P_{1}[/tex] = 785 mm Hg (mm Hg = 0.00131579) = 1.032 atm

[tex]P_{2}[/tex] = 0.300 atm,       [tex]V_{2}[/tex] = ?

Formula used to calculate volume is as follows.

[tex]P_{1}V_{1} = P_{2}V_{2}[/tex]

Substitute the value into above formula as follows.

[tex]P_{1}V_{1} = P_{2}V_{2}\\1.032 atm \times 1.80 L = 0.300 atm \times V_{2}\\V_{2} = 6.192 L[/tex]

Thus, we can conclude that the volume of the balloon up there is 6.192 L.

Answer:

[tex]v_2=6,48*10^{-4}L[/tex]

Explanation:

From the question we are told that:

Volume of hydrogen  [tex]V_1=30mL=>30*10^{-3}[/tex]

Temperature [tex]T_1=24C=>24+273=>297k[/tex]

Pressure of water [tex]P_1=22.4torr=>\frac{22.4}{760}=0.0295atm[/tex]

Let

STP(Standard Temperature and pressure)

 [tex]T_2=273K[/tex]

 [tex]P_2=1atm[/tex]

Generally the equation for ideal gas is mathematically given by

 [tex]\frac{p_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]

Therefore

 [tex]v_2=\frac{P_1v_1T_2}{T_1P_2}[/tex]

 [tex]v_2=\frac{0.0295*30*10^{-3}*273}{297*1}[/tex]

 [tex]v_2=6.48*10^{-4}L[/tex] (at STP(Standard Temperature and pressure))

Answer: Moles are found in a 350.mL solution of 13.5M [tex]HNO_{3}[/tex] are 4.725 mol.

Explanation:

Given: Volume = 350 mL (1 mL = 0.001 L) = 0.350 L

Molarity = 13.5 M

Molarity is the number of moles of a substance present in a liter of solution.

Therefore, moles of [tex]HNO_{3}[/tex] present in the given solution are calculated as follows.

[tex]Molarity = \frac{moles}{Volume (in L)}\\13.5 M = \frac{moles}{0.350 L}\\moles = 4.725 mol[/tex]

Thus, we can conclude that moles found in a 350.mL solution of 13.5M [tex]HNO_{3}[/tex] are 4.725 mol.

Answer:

Q = 2.60 • [tex]10^{3}[/tex] J

Explanation:

Our specific heat capacity equation is:

Q = mC∆T

Q is the energy in joules.

m is the mass of the substance.

∆T is the temperature chance.

Let's plug in what we know.

Q = 76.0(2.22)(15.4)

Multiply.

Q = 2598.288

We want three significant figures.

Q = 2.60 • [tex]10^{3}[/tex]

or

Q = 2590 J

Hope this helps!

Answer:6,985.008

Explanation:

so the hear formula is mass times specific heat times change in temperature (kelvin) so what i did was got the change in temperature (41.4 K) and multiplied that times 2.22 J/(g•K)and multiplied that by 76 grams of Octane to get the Answer (not in scientific notation)

Answer:

Sn --> Sn2+ + 2e-

Explanation:

At anode oxidation reaction occur. In this reaction Sn is getting oxidized to state +2 while Ag is reduced from +1 to 0.

Hence, reaction at anode will be  

Sn (s) --> Sn2+ (aq) + 2e-

At cathode the following reaction occur

2 Ag⁺ + 2e- ---> 2Ag (s)
