How many Carbon Atoms are there on the PRODUCT SIDE
Answer: There are 6 carbon atoms on the product side.
Explanation:
The given reaction equation is as follows.
[tex]6CO_{2} + 6H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2}[/tex]
Species present on the left side of an arrow in a chemical equation depicts the reactants.
Species present on the right side of an arrow in a chemical equation depicts the products.
Hence, products in the given reaction equation are [tex]C_{6}H_{12}O_{6}[/tex] and [tex]6O_{2}[/tex].
Therefore, there are 6 carbon atoms present on the product side.
Thus, we can conclude that there are 6 carbon atoms on the product side.

De la siguiente reacción química Fe2O3 + 3 H2O → __Fe(OH)3 para que se cumpla el balanceo en ella, en el espacio qué coeficiente estequiométrico se debe asignar
Answer:
Para que se cumpla el balanceo en la reacción química, en el espacio se debe asignar 2 como coeficiente estequiométrico.
Explanation:
La ley de conservación de la materia establece que, dado que no se puede crear ni destruir ningún átomo en una reacción química, el número de átomos que están presentes en los reactivos debe ser igual al número de átomos presentes en los productos.
Luego, debes equilibrar la ecuación química. Para eso, primero debe mirar los subíndices al lado de cada átomo para encontrar el número de átomos en la ecuación. Si el mismo átomo aparece en más de una molécula, debes sumar sus cantidades.
Los coeficientes ubicados frente a cada molécula indican la cantidad de cada molécula para la reacción. Este coeficiente puede modificarse para equilibrar la ecuación, del mismo modo que nunca debe alterar los subíndices.
Al multiplicar el coeficiente mencionado por el subíndice, obtienes la cantidad de cada elemento presente en la reacción.
En este caso la reacción química es:
Fe₂O₃ + 3 H₂O ⇒ ____ Fe(OH)₃
Entonces, teniendo en cuenta todo lo anterior, se puede determinar la cantidad de elementos en cada lado de la ecuación:
Lado izquierdo: 2 hierro Fe, 6 oxígeno O y 6 hidrógenos H Lado derecho: 1 hierro Fe, 3 oxígeno O y 3 hidrógenos HSe puede observar que la reacción química no esta balanceada porque se tiene diferentes cantidades de cada elemento a cada lado de la reacción. Para equilibrarla, se comienza balanceando el hierro. Para eso, el coeficiente estequiométrico debe ser dos:
Fe₂O₃ + 3 H₂O ⇒ 2 Fe(OH)₃
Entonces:
Lado izquierdo: 2 hierro Fe, 6 oxígeno O y 6 hidrógenos H Lado derecho: 2 hierro Fe, 6 oxígeno O y 6 hidrógenos HAhora, a cada lado de la reacción se tiene la misma cantidad de cada elemento, por lo que la reacción esta balanceada.
Para que se cumpla el balanceo en la reacción química, en el espacio se debe asignar 2 como coeficiente estequiométrico.

17. A sample of oxygen gas has volume 150.0 mL, at 0.947 atm, what will be the volume of the gas at 750.12 mm of Hg if temperature remain constant.
Answer:
143.9 mL is the new volume for the gas.
Explanation:
Let's apply one of the gases law to solve this problem:
Boyle's law states that the product of pressure and volume remains constant when the T° is not modified.
P₁ . V₁ = P₂ . V₂
Be careful because we have T° in mmHg. We need to convert to atm:
750.12 mmHg . 1 atm / 760 mmHg = 0.987 atm
We replace data:
150 mL . 0.947 atm = 0.987 atm . V₂
V₂ = (150 mL . 0.947 atm) / 0.987 atm
V₂ = 143.9 mL
This term P . V comes from the Ideal Gases Law
P . V = n . R . T
What is the pressure of a gas at STP?
A. O atm
B. 2 atm

Una masa de aire ocupa un volumen de5litro a una temperatura de 120c Cual será el nuevo volumen si la temperatura se reduce ala mitad. Un gas ideal ocupa un volumen de 4000ml a una presión absoluta de 1500 kilo pascal Cual será la presión si el gas es comprimido lentamente hasta 750 kilo pascal a temperatura constante? Un gas ocupa un volumen de 200 litros a 95c y 782mmHg Cual será el volumen ocupado por dicho gas a 65cyn815mmHg
Answer:
1. [tex]V_2=2.5L[/tex]
2. [tex]V_2=8000mL[/tex]
3. [tex]V_2=176.3L[/tex]
Explanation:
¡Hola!
En este caso, dada la información para estos problemas, procedemos de la siguiente manera, basado en las leyes de los gases ideales:
1. Una masa de aire ocupa un volumen de 5 litros a una temperatura de 120 °C Cual será el nuevo volumen si la temperatura se reduce a la mitad:
Aqui, utilizamos la ley de Charles, asegurándonos que la temperatura está en Kelvin:
[tex]\frac{T_2}{V_2} =\frac{T_1}{V_1} \\\\V_2 =\frac{V_1T_2}{T_1} \\\\V_2 =\frac{5L*196.5K}{393K} \\\\V_2=2.5L[/tex]
2. Un gas ideal ocupa un volumen de 4000 ml a una presión absoluta de 1500 kilo pascal Cual será la presión si el gas es comprimido lentamente hasta 750 kilo pascal a temperatura constante?
Aquí, utilizamos la ley de Boyle, dado que la temperatura se mantiene constante, calculando el volumen, ya que lo que se da es la presión final:
[tex]\neq P_2V_2=P_1V_1\\\\V_2=\frac{P_1V_1}{P_2}\\\\ V_2=\frac{4000mL*1500kPa}{750kPa}\\\\V_2=8000mL[/tex]
3. Un gas ocupa un volumen de 200 litros a 95°C y 782 mmHg Cual será el volumen ocupado por dicho gas a 65°C y 815 mmHg:
Aquí, utilizamos la ley combinada de los gases ideales, asegurándonos que las temperaturas están en Kelvin:
[tex]\frac{T_2}{P_2V_2} =\frac{T_1}{P_1V_1} \\\\V_2 =\frac{P_1V_1T_2}{P_2T_1} \\\\V_2 =\frac{782mmHg*200L*338K}{815mmHg*368K}\\\\V_2=176.3L[/tex]

PLEASE ANSWER QUICKLY!! 25. Which gas sample contains a total of 3.0 x 1023 molecules?
A) 71 g of Cl2
B) 2.0 g of H2
C) 14 g of N2
D) 38 g of F2
Answer:
14 g of N2
Explanation:
If we look at the options, we will notice that the correct answer needs to be a gas that has about half of the molecular mass of the gas.
If we consider nitrogen gas whose molecular mass is 28g/mol, half of the molecular mass is 14 g.
So;
28g of N2 contains 6.02 × 10^23 molecules of N2
14g of N2 contains 14 × 6.02 × 10^23 /28
= 3.0 x 10^23
3. What are the planets called that are mostly made of gas?
Explanation:
The gas planets are Jupiter, Saturn, Uranus and Neptune.
Answer:
A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. These four large planets, also called jovian planets after Jupiter, reside in the outer part of the solar system past the orbits of Mars and the asteroid belt. Jupiter and Saturn are substantially larger than Uranus and Neptune, and each pair of planets has a somewhat different composition.Although there are only four large planets in our solar system, astronomers have discovered thousands outside of it, particularly using NASA's Kepler Space Telescope. These exoplanets (as they are called) are being examined to learnmore about how our solar system came to be.Explanation:
hopeit helps...In a chemical reaction, the number of moles of the reactants
A.

B.
depends on the amount of product that is formed.
C.
should never be equal to the number of moles of the products.
D.
may or may not be equal to the number of moles of the products.
Answer:
may or may not be equal to the number of moles of the products.
Explanation:
A chemical reaction involves the interaction between reactants to yield products. The number of moles of reactants and products in the system depends on the stoichiometry of the reaction.
The balanced reaction equation shows us the number of moles of reactants and products involved in the reaction.
Hence, in the balanced chemical reaction equation; the number of moles of reactants may or may not be equal to the number of moles of the products.

2 NABr + Ca(OH)2 = CaBr2 + 2 NaOH How many moles of CaB 2 are produced, if 14.72 moles of NaBr and excess Ca(OH) 2 react?
Answer: 7.36 moles of [tex]CaBr_2[/tex] will be produced.
Explanation:
We are given:
Moles of NaBr = 14.72 moles
The given chemical equation follows:
[tex]2NaBr+Ca(OH)_2\rightarrow CaBr_2+2NaOH[/tex]
By the stoichiometry of the reaction:
2 moles of NaBr produces 1 mole of calcium bromide
So, 14.72 moles of NaBr will produce = [tex]\frac{1}{2}\times 14.72=7.36mol[/tex] of calcium bromide
Hence, 7.36 moles of [tex]CaBr_2[/tex] will be produced.
