Answer:
because the partieals are cold are pushed away
Explanation:
Answer:
Scientific Law
Explanation: Earth will ALWAYS attract objects to the center of itself because of gravity. This will never be disproven.
Answer:
Empirical Formula = NH₄NO₃ (Ammonium Nitrate)
Solution:
Step 1: Calculate Moles of each Element;
Moles of N = %N ÷ At.Mass of N
Moles of N = 35.0 ÷ 14
Moles of N = 2.5 mol
Moles of O = %O ÷ At.Mass of O
Moles of O = 59.96 ÷ 16
Moles of O = 3.7475 mol
Moles of H = [100% - (%N + %O)] ÷ At.Mass of H
Moles of H = [100% - (35.0 + 59.96)] ÷ 1.008
Moles of H = [100% - 94.96] ÷ 1.008
Moles of H = 5.04 ÷ 1.008
Moles of H = 5 mol
Step 2: Find out mole ratio and simplify it;
N H O
2.5 5 3.7475
2.5/2.5 5/2.5 3.7475/2.5
1 2 1.5
Multiply Mole Ratio by 2,
2 4 3
Result:
Empirical Formula = N₂H₄O₃
Or,
Empirical Formula = NH₄NO₃
This empirical formula is also a Molecular Formula for Ammonium Nitrate a well known Fertilizer and often misused in the formation of Explosives.
Answer:
250L
Explanation:
Data;
V1 = 200L
P1 = 10atm
T1 = 400K
T2 = 100K
P2 = 2atm
V2 = ?
To solve this question, we'll have to use the combined gas equation which is a combination of Boyle's law, Charles law and pressure law.
From combined gas equation,
(P1 × V1) / T1 = (P2 × V2) / T2
P1 × V1 × T2 = P2 × V2 × T1
Solve for V2,
V2 = (P1 × V1 × T2) / P2 × T1
V2 = (10 × 200 × 100) / (2 × 400)
V2 = 200,000 / 800
V2 = 250L
The final volume of the gas is 250L
