Answer:
High temperature and low pressure
Explanation:
According to the kinetic molecular theory, gases are composed of small particles called molecules which are in constant motion.
At high temperature and low pressure, gas molecules possess high kinetic energy and move at high velocities hence intermolecular interaction is almost none existent and real gases approach the behavior of ideal gases.
Answer:
D. Silicon
Explanation:
A anion is a negatively charge ion resulting from the imbalance of protons and neutrons where there are more electrons than protons. Silicon has 4 valence electrons and is more likely to form an ionic bond with another atom(s) that will give it the 4 electrons it needs to become stable.
Answer:
Mass of 1 litre of this gas at 273 degree Celsius and 1140 mm Hg pressure is
3 grams. So, (T1) = (273 + 273) degree Absolute = 546 degree Absolute and
(P1) = (760 + 1140) mm Hg = 1900 mm Hg and (V1) = 1 Litre
First, we have to find out how much volume does it occupy at NTP; (T2) = 273 degree Absolute and (P2) = 760 mm Hg.
So, (V2) = (1900*1 / 546)*(273 / 760) = 1.25 litre.
So, the mass of 1.25 litre volume of this gas = 3 grams
Therefore, the mass of 22.4 litre volume of this gas = (3*22.4 / 1.25) grams
= 53.76 grams.
So, the gram molecular mass of the gas is 53.76.

Answer:
1.Where is blue made?
ans-Types. Blue pigments were originally made from minerals such as lapis lazuli, cobalt and azurite, and blue dyes were made from plants; usually woad in Europe, and Indigofera tinctoria, or true indigo, in Asia and Africa. Today most blue pigments and dyes are made by a chemical process.
2.what does bile do?
ans-Bile is a fluid that is made and released by the liver and stored in the gallbladder. Bile helps with digestion. It breaks down fats into fatty acids, which can be taken into the body by the digestive tract.
3. What is duodenum
The duodenum is the first part of the small intestine. It is located between the stomach and the middle part of the small intestine, or jejunum. After foods mix with stomach acid, they move into the duodenum, where they mix with bile from the gallbladder and digestive juices from the pancreas
