If 9.65 mole of methane reacts with oxygen to produce carbon dioxide and water, what mass of water is produced?

Answers

Answer:

347.4 (19.3 mole)

Explanation:

CH4 + 2O2 = CO2 + 2H2O

1(mole) - 9.65(mole)

2(mole) - x ⇒x = 9.65*2=19.3

m=n*M ⇒ m= 19.3*(1*2+16)= 19.3*18=347.4(g)

What is the difference between speed and acceleration?
Please help :)

Answers

Answer:

Speed is how fast you are going at the moment but acceleration is how fast you are building up speed to get to a set point

Explanation:

En una planta de energía, se produce CO2 gracias a la reacción de combustión del material orgánico con oxígeno para producir CO2, SO2, SO3, NO, NO2 y H2O que son los causantes del efecto invernadero, el SO2 reacciona con H2O para formar H2SO3, causante de la lluvia ácida. En condiciones de gas ideal el SO2 se encuentra a una temperatura de 100°C y 0,5 atm de presión, el volumen ocupado generalmente es de 25 L. 5. La ecuación para hallar el número de moles debe ser: a. Gases ideales: relación entre todas las variables que influyen sobre los gases b. Boyle: relación entre volumen y presión c. Charles: relación entre el volumen y la temperatura d. Gay Lussac: relación entre la presión y la temperatura

Answers

Answer:

a. Gases ideales: relación entre todas las variables que influyen sobre los gases

Explanation:

La ecuación del gas ideal da la relación entre las variables; presión, volumen, temperatura y número de moles.

Según la ecuación del gas ideal; PV = nRT

P = presión del gas

V = volumen del gas

n = Número de moles del gas

R = constante de gas

T = temperatura del gas

El número de moles de SO2 se obtiene de;

n = PV / RT

n = 0,5 * 25 / 0,082 * 373

n = 12,5 / 30,586

n = 0,41 moles

How many moles of AgNO3 must react to form 0.854 mol Ag?
mol AgNO3

Answers

Answer:

0.854

Explanation:

The equation of its dissolution in water is: AgNO3 → Ag + (aq)  +  NO3- (aq)

and     AgNO3 →   Ag + (aq)  +  NO3- (aq)

         1 mol          1mol                1mol

            ?  --------   0.854mo

so for finding the value, it is sufficients to complute 1 x 0.854 mol =0.854 mol

so,  0.854 mol is required for the reaction to form 0.854 mol of Ag

Rhodium-122
Indium-110
Palladium-109

Answers

Answer:

Rhodium-122 < Palladium-109 < Silver-109  <  Cadmium-106 < Indium-110

Explanation:

Atomic number - Number of protons.

The number displayed at the end of the element in this question represents the mass number (Number of protons + Number of neutrons).

The atomic number of the isotopes are given below;

Silver-109  --> 47

Cadmium-106  --> 48

Rhodium-122   --> 45

Indium-110   --> 49

Palladium-109  --> 46

Arranging in order of increasing atomic number from lowest to highest;

Rhodium-122 < Palladium-109 < Silver-109  <  Cadmium-106 < Indium-110

Air is made up mostly of O2, N2, and CO2. If the total pressure of air is 765mmHg and P(N2) = 0.79 atm and P(CO2) = 0.05 atm, then what is the partial pressure of the O2?

Answers

Answer:

the partial pressure of the O2 is 0.167 atm

Explanation:

The computation of the partial pressure of the O2 is shown below:

As we know that

P = P_N2 + P_O2 + P_CO2

P_O2 = P - P_N2 -  P_CO2

= (1.007 - 0.79 - 0.05)

= 0.167 atm

Hence, the partial pressure of the O2 is 0.167 atm

we simply applied the above formula

Explain how low atomspheric oxygen levels affected alligators growth in terms of celluar respiration

Answers

Answer:

Answer: Hyperoxic alligators show significantly lower breathing rates than their siblings in normoxic and hypoxic groups. Conversely, each breath supports greater oxygen consumption in hyperoxic animals than in other groups. Statistical significance between groups was calculated by ANOVA with post hoc Tukey-Kramer

The explanation regarding the less atmospheric oxygen levels impacted the alligators growth should be because of Hyperbolic alligators.

What is Hyperbolic alligators?

There should be less breathing rate and the consumption of the oxygen should be high per breath.

The compensatory cardiopulmonary remodeling, the growth of the hypnotic alligators should be constrained by the less temperature with respect to the supply of the oxygen that should limited the food utilization capacity.
