Explanation:
2.00 L of a gas is collected at 25.0°C and 745.0 mmHg. What is the volume at 760.0 mmHg
and 273K. someone help i only have 2 mins left
Answer:
1.79 L
Explanation:
Step 1: Given data
Initial volume of the gas (V₁): 2.00 LInitial temperature of the gas (T₁): 25.0 °CInitial pressure of the gas (P₁): 745.0 mmHgFinal volume of the gas (V₂): ?Final temperature of the gas (T₂): 273 KFinal pressure of the gas (P₂): 760.0 mmHgStep 2: Convert T₁ to Kelvin
We will use the following expression.
K = °C + 273.15
K = 25.0 °C + 273.15 = 298.2 K
Step 3: Calculate the final volume of the gas
We will use the combined gas law.
P₁ × V₁ / T₁ = P₂ × V₂ / T₂
V₂ = P₁ × V₁ × T₂ / T₁ × P₂
V₂ = 745.0 mmHg × 2.00 L × 273 K / 298.2 K × 760.0 mmHg = 1.79 L

Which of the following best describes an Arrhenius acid-base reaction?
O A. Acid + base = H+ + OH-
B. Acid + base = salt + water
C. Acid + base = conjugate base + conjugate acid
D. Acid + base =
H20
Answer:
B. Acid + base = salt + water
Explanation:
In accordance to the proposal of a scientist called Svante Arrhenius, an acid is a substance that increases the H+ concentration of a solution by dissociating into it while the base increases the OH- concentration of a solution by dissociating into it. Furthermore, Arrhenius stated that this two ions combine in an aqueous solution to give water.
Hence, Arrhenius acid-base reaction is the combination of an acid and base to produce salt and water as products. That is; Acid + base = salt + water.

One mole of aluminum contains 6.022 × 10²³ atoms. This number is called Avogadro number. Therefore, 0.55 moles of aluminum contains 3.31 × 10²³ atoms.
What is Avogadro number ?One mole of any substance contains 6.022 × 10²³ atoms. This number is called Avogadro number. One mole of every elements contains Avogadro number of atoms.
Aluminum is 13th element in periodic table. It shows metallic properties as well as some non-metallic properties. The symbol of aluminum is Al. It forms compounds mostly through covalent bonding.
One mole of aluminum contains 6.022 × 10²³ atoms.
Thus, number of atoms in 0.55 moles = 0.55 × 6.022 × 10²³ = 3.31 × 10²³ atoms.
Therefore, the number of Al atoms in 0.55 moles is 3.31 × 10²³ .
