Loud speaker A vibrates 200 times each second. Loud speaker B vibrates 400 times each second.a)What is the frequency of the sound produced by Loud speaker A ? Give the value and unit.
b)Which loudspeaker produces higher frequency of vibrations?
(Show calculations)
Answer:
For a: The frequency produced by loudspeaker A is 200 Hz
For b: Loudspeaker B produces a higher frequency of vibrations.
Explanation:
To calculate the frequency of a loudspeaker, we use the formula:
[tex]\nu=\frac{\text{Number of vibrations}}{\text{Time period}}[/tex] ......(1)
where,
[tex]\nu[/tex] = frequency
For loudspeaker A:Number of vibrations = 200
Time period = 1 second
Putting values in equation 1:
[tex]\nu_A=\frac{200}{1s}=200Hz[/tex]
For loudspeaker B:Number of vibrations = 400
Time period = 1 second
Putting values in equation 1:
[tex]\nu_B=\frac{400}{1s}=400Hz[/tex]
Hence, the frequency produced by loudspeaker A is 200 Hz and loudspeaker B produces a higher frequency of vibrations.

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]

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.

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:

Answer:
308.2 g of NH₃.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
3H₂ + N₂ —> 2NH₃
Next, we shall determine the mass of N₂ that reacted and the mass of NH₃ produced from the balanced equation. This can be obtained as follow:
Molar mass of N₂ = 2 × 14 = 28 g/mol
Mass of N₂ from the balanced equation = 1 × 28 = 28 g
Molar mass of NH₃ = 14 + (3×1)
= 14 + 3 = 17 g/mol
Mass of NH₃ from the balanced equation = 2 × 17 = 34 g
Summary:
From the balanced equation above,
28 g of N₂ reacted to produce 34 g of NH₃.
Finally, we shall determine the mass of NH₃ produced by the reaction of 253.8 g of N₂. This can be obtained as illustrated below:
From the balanced equation above,
28 g of N₂ reacted to produce 34 g of NH₃.
Therefore, 253.8 g of N₂ will react to produce = (253.8 × 34)/28 = 308.2 g of NH₃.
Thus, 308.2 g of NH₃ were obtained from the reaction.

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
Urgent: Suppose that 14.9 mL of HNO3 is neutralized by 53.1 mL of a 0.0048 M solution of KOH in a titration. Calculate the concentration of the HNO3 solution.
Answer:
0.017 M
Explanation:
The reaction that takes place is:
HNO₃ + KOH → KNO₃ + H₂OFirst we calculate how many KOH moles reacted, using the given volume and concentration:
53.1 mL * 0.0048 M = 0.255 mmolAs 1 mmol of KOH reacts completely with 1 mmol of HNO₃, in 14.9 mL of the HNO₃ solution there were 0.255 HNO₃ mmoles.
With that in mind we can calculate the concentration of the HNO₃ solution using the calculated number of moles and given volume:
0.255 mmol / 14.9 mL = 0.017 MNa + Cl --> NaCl
