Answer:
4.55 LExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we're finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{195000 \times 3.5}{150000} = \frac{682500}{150000} \\ = 4.55[/tex]
We have the final answer as
4.55 LHope this helps you

Answer:
hydrogen and cloride + hydrogen
butanoic acid + 1-pentanol
catalyst
→ water +X
Given the equation:
To which class of organic compounds does product X belong?
1. alcohol
2. Ester
3. Ether
4. 4. alkane
Answer: X is an Esther
Explanation: alcohol and carboxylate acid forms esters
When a carboxylic acid and alcohol react then-new substance is produced from esterification and hence is called an ester. Thus, option 2 is correct.
What is esterification?Esterification is the process to make esters from carboxylic acids and alcohol in the presence of an acid catalyst (dry sulphuric acid). The -COOH group of the carboxylic acids contributes to the formation of the esters.
The esterification reactions are reversible reactions and occur at a slower pace. The reaction between an acid and alcohol is shown as:
Butanoic acid + 1-pentanol (catalyst) → water + ester
Therefore, option 2. ester is produced.

Pedro adds 3.23 moles of helium to a balloon that already contained 4.51 moles of helium creating a balloon with a volume of 9.87 liters. What was the volume of the balloon before the addition of the extra gas?
Answer:
7.The answer is 2.13 because if u add 3.23 and 4.51 and the answer is 7.74 and u add 2.13 to get 9.87. 3.23 + 4.51 + 2.13 is 9.87

Electron configuration is the representation of the distribution or arrangement of electrons in orbital shells and subshells of a particular atom. IN this question the given electron configuration is -
1s^22s^22p^63s^23p^64s^1
By the configuration, it is clear that it belongs to
- the s group as the last electron is n s orbital and
- only 1 electron which means it belongs to group 1 in the periodic table
- last orbital is 4 so it is from the 4th period
- total electron = 19
Thus, the correct answer is - Potassium or K.

Why do plants need sunlight for photosynthesis?
Explanation: Plants using photosynthesis will take in carbon dioxide from the air, bring up water from the roots, and use sunlight as the energetic source to create sugar from water and carbon dioxide. Plants contain a molecule called chlorophyll, and the chlorophyll is what absorbs the sunlight
Describe how crude oil is separated into fractions by fractional distillation.
Answer:
Crude oil is separated by fractional distillation. Crude oil is heated to vaporize the different hydrocarbons in a tank which is cool at the top and hot at the bottom. The vapours then rise and the different hydrocarbons condense at their specific boiling points, allowing them to be separated.

How many joules are required to heat 15 grams of ice from -200⁰ to 1400⁰ C?
Answer: A heat energy of 50160 joules are required to heat 15 grams of ice from [tex]-200^{o}C[/tex] to [tex]1400^{o}C[/tex].
Explanation:
Given : mass of ice = 15 g
Convert grams into kg as follows,
[tex]1 g = 0.001 kg\\15 g = 15 g \times \frac{0.001 kg}{1 g}\\= 0.015 kg[/tex]
Initial temperature = [tex]-200^{o}C[/tex]
Final temperature = [tex]1400^{o}C[/tex]
Formula used to calculate the amount of heat energy is as follows.
[tex]q = m \times C \times (T_{2} - T_{1})[/tex]
where,
q = heat energy
m = mass of substance
C = specific heat of substance (ice here has C = [tex]2090 J/kg ^{o}C[/tex])
[tex]T_{1}[/tex] = initial temperature
[tex]T_{2}[/tex] = final temperature
Substitute the values into above formula as follows.
[tex]q = m \times C \times (T_{2} - T_{1})\\= 0.015 kg \times 2090 J/kg^{o}C \times [1400 - (-200)]^{o}C\\= 50160 J[/tex]
Thus, we can conclude that 50160 joules are required to heat 15 grams of ice from [tex]-200^{o}C[/tex] to [tex]1400^{o}C[/tex].
How does the kinetic theory of gases explain the weather changes happening in the troposphere? You can also research on the internet using keywords such as troposphere, atmosphere layers, and weather changes.
Answer: According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often.

Shoals are raised landforms made of sand and gravel that are commonly found in Florida. They are often called sandbars and are located in and around bodies of water such as oceans, rivers, and lakes. Which factor most commonly causes shoals to form or change shape?
Heavy rain fall most commonly causes shoals to form or change shape making depressions and bars in the sand.
What causes a shoal ?Wave shoaling occurs when surface waves slow down, their wave height rises, and the space between waves narrows as they approach shallow water, like a beach. The waves are said to shoal because of this action, which is known as shoaling.
The shoal, a buildup of silt that might be hazardous to ships in a river channel or on a continental shelf.
Conventionally, it is assumed that the continental shelf is less than 10 metres below sea level at low tide. Shoals are created mostly by the same processes that result in offshore bars.
Thus, Heavy rain fall causes shoals to produce and change shape creating depressions and bars in the sand.

Cuántos mililitros de agua hay en 3 litros de una botella de naranjas y las solucion tiene una concentracion de 20% v/v
Respuesta:
2400 mL
Explicación:
Paso 1: Información dada
Volumen de solución: 3 L (3000 mL)Concentración de naranja: 20 % v/vPaso 2: Calcular el volumen de naranja
La concentración de naranja es de 20 % v/v, es decir, cada 100 mL de solución hay 20 mL de naranja.
3000 mL Sol × 20 mL Naranja/100 mL Solución = 600 mL Naranja
Paso 3: Calcular el volumn de agua
El volumen de soluciónes igual a la suma de los volúmenes de naranja y agua.
VSolución = VNaranja + VAgua
VAgua = VSolución - VNaranja
VAgua = 3000 mL - 600 mL = 2400 mL
