How many moles of o2 are produced from 6.2 moles of water?
How many moles of o2 are produced from 6.2 moles of water?
3.1 moles
When 12 moles of o2 reacts with 1.1 mole of c10h8 What is the limiting reactant?
Explanation: it is so bcz 1 mole of C10H8O must requires 12 moles of o2 so 6 moles must require 6*12 which is 72 moles. so o2 is limiting reagant.
How many grams of aluminum sulfate would be formed if 250g h2so4 completely reacted with aluminum?
290.8 grams
What is the first thing you must do to solve a stoichiometry problem?
Almost all stoichiometric problems can be solved in just four simple steps: Balance the equation. Convert units of a given substance to moles. Using the mole ratio, calculate the moles of substance yielded by the reaction.
How many moles of hydrogen are needed to completely react with 2 moles nitrogen?
Your question specified 2 moles of nitrogen. I would be quite justified in assuming that the questioner meant 2 moles of dinitrogen gas, i.e. the equivalent of 4 moles of NITROGEN atoms. Thus, if 2 moles of dinitrogen gas are specified, 6 moles of dihydrogen gas are required.
What is the mole ratio of oxygen to pentane?
8 : 1
What is the mole ratio of pcl3 to pcl5?
1 : 1
What is Mole used for?
Mole, also spelled mol, in chemistry, a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
Is a mole equal to a gram?
The mass of 1 mole of a substance is equal to its relative atomic or molecular mass in grams.
How can you apply the concept of mole in real life?
In chemistry, the mole is a unit used to talk about atoms. It is similar to other units we use everyday. For example, you might walk into the local doughnut shop and order a dozen doughnuts. In doing so, you know that you will get 12 of these snacks and the clerk knows to give you 12.
What is a mole equal to?
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant.
What is Mole on human body?
Moles are a common type of skin growth. They often appear as small, dark brown spots and are caused by clusters of pigmented cells. Moles generally appear during childhood and adolescence. Most people have 10 to 40 moles, some of which may change in appearance or fade away over time.
What does 1 gram mole mean?
A mass of a substance in grams numerically equal to its molecular weight. Example: A gram-mole of salt (NaCl) is 58.44 grams.
What does Avogadro’s law mean?
Avogadro’s law, a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules.
Why is Avogadro’s law important?
1 Answer. Avogadro’s law investigates the relationship between the amount of gas (n) and volume (v). It’s a direct relationship, meaning the volume of a gas is directly propotional to the number of moles the gas sample present. The law is important because helps us save time and money in the long-run.
How do you prove Avogadro’s law?
At constant pressure and temperature, Avogadro’s law can be expressed via the following formula:
- V ∝ n.
- V/n = k.
- V1/n1 = V2/n2 ( = k, as per Avogadro’s law).
- PV = nRT.
- V/n = (RT)/P.
- V/n = k.
- k = (RT)/P.
- One mole of helium gas fills up an empty balloon to a volume of 1.5 litres.
What does Boyles law mean?
This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant. …
What is an example of Boyle’s Law in real life?
You can observe a real-life application of Boyle’s Law when you fill your bike tires with air. When you pump air into a tire, the gas molecules inside the tire get compressed and packed closer together. This increases the pressure of the gas, and it starts to push against the walls of the tire.
What is Charles Law in simple terms?
Charles’s law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant. It is a special case of the general gas law and can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas.
What type of relationship is Charles Law?
Charles’ Law is the formal description of this relationship between temperature and volume at a fixed pressure. This relationship allows changes in the volume of a fixed mass * of gas to be calculated given a change in temperature.
What is Charles law state?
The physical principle known as Charles’ law states that the volume of a gas equals a constant value multiplied by its temperature as measured on the Kelvin scale (zero Kelvin corresponds to -273.15 degrees Celsius).
Why is Charles law a direct relationship?
The law states that if a quantity of gas is held at a constant pressure, there is a direct relationship between its volume and the temperature, as measured in degrees Kelvin. Think of it this way. As the temperature increases, the molecules within any given gas begin to move around more quickly.
How does Charles law affect the human body?
Due to Charles’s law, as air is warmed in the conducting division of the respiratory system, it will increase in volume. Intra-alveolar pressure is the pressure of the air within the alveoli, which changes during the different phases of breathing (Figure 2).
What is a good example of Charles Law?
One easy example of Charles’ Law is a helium balloon. If you fill a helium balloon in a warm or hot room, and then take it into a cold room, it shrinks up and looks like it has lost some of the air inside.
Who invented Charles Law?
Joseph Louis Gay-Lussac
What is a real life example of Avogadro’s law?
A flat tire takes up less space than an inflated tire, because it contains less air. Lungs expand as they fill with air. Exhaling decreases the volume of the lungs. A balloon filled with helium weighs much less than an identical balloon filled with air.
