<u>Answer:</u> The number of moles of gas present is 0.276 moles
<u>Explanation:</u>
To calculate the number of moles of gas, we use the equation given by ideal gas:
PV = nRT
where,
P = Pressure of the gas = 725 mm Hg
V = Volume of the gas = 7.55 L
n = number of moles of gas = ?
R = Gas constant =
T = Temperature of the gas =
Putting values in above equation, we get:
Hence, the number of moles of gas present is 0.276 moles
Legumes are foods which are high in proteins and carbohydrates but low in fat. They include peas, beans soya beans among other. These foods are excellent sources of proteins and also provide other nutrients vitamins and minerals. The protein makes them a high-quality source of food for food-insecure populations whose diet is deficient of proteins.
Assuming you want a true or false answer, this is true.
Answer:
Element.
General Formulas and Concepts:
<u>Chemistry</u>
- Reading a Periodic Table
- Diatomic Elements
Explanation:
Diatomic Elements are elements that are bonded to themselves. Naturally, these elements are not found alone in nature.
Diatomic Elements:
Hydrogen
Nitrogen
Oxygen
Fluorine
Chlorine
Bromine
Iodine
Since Nitrogen is a diatomic element, we would find Nitrogen in nature as N₂.
The heat energy from the fire is transferred to the pot by
- <em>radiation</em> — the hot coals radiate heat to the pot.
- <em>convection</em> — the hot gases from the fire travel upward until they reach the pot
The pot absorbs the heat energy and <em>conducts</em> the heat to the water inside.
The hot water <em>conducts</em> heat to the peas in three steps:
- warming the frozen ice and peas to 0 °C.
- thawing the ice and peas at 0 °C.
- heating the peas to 100 °C and cooking them at that temperature.
<em>Note</em>: Heat always flows spontaneously from a hotter to a cooler object.
