Answer:
P= 36.76atm
Explanation:
According to the adeal gas equation P = nRT/ V
n= 3.6 mol, T = 485K, V = 3.90L R = 0.0821Latm/molK
P= 3.6× 0.0821× 485 / 3.9
= 36.76atm
Answer:
Any situation that has a path that stops at the same position that it started from has a displacement of zero.
Explanation:
Fossils provide a window in Earth's history by showing us how they existed in the past. They can be dated through several ways and can show us how animals and plants have evolved over millions of years. Also, fossils can help us better understand ancient disasters by the inclusion of elements (such as <span>volcanic ash or dust from major space object impacts) and how they affected the life on earth)</span>
The amount of carbon combined with oxygen in order to form Carbon Dioxide(CO₂) is 12 grams
The Law of Multiple proportions is one of the basic laws in chemistry along with the Law of Definite proportion. This law was proposed by John Dalton in 1803. The law states that if two elements react to form one or more compounds then the ratio of masses of both the elements is in the ratio of small whole numbers.
It is known that Carbon can form two different compounds while reacting with Oxygen that is: Carbon Monoxide, Carbon Dioxide. For Carbon Monoxide, 12g of Carbon needs to react with 16g of Oxygen. Whereas, In Carbon Dioxide, 12g of Carbon needs to react with 32g of Oxygen. So the mass of Carbon is equal in both cases is 12g.
C(12g) + O(16g) ⇒ CO (Carbon Monoxide)
C(12g) + 2O(32g) ⇒ CO₂ (Carbon Dioxide)
