Answer:
The temperature at 581.2 mL volume was 242.8 K.
Explanation:
Using Charle's law
Given ,
V₁ = 581.2 mL
V₂ = 830.5 mL
T₁ = ?
T₂ = 347 K
Using above equation as:
<u>The temperature at 581.2 mL volume was 242.8 K.</u>
Answer:
The answer to your question is the second option
Explanation:
Reaction
Al₂(SO₄)₃ + KOH ⇒ Al(OH)₃ + K₂SO₄
Process
1.- Check if the reaction is already balanced
Reactants Elements Products
2 Aluminum 1
3 Sulfur 1
13 Oxygen 7
1 Potassium 2
1 Hydrogen 3
The reaction is unbalanced
2.- Balance the reaction
1Al₂(SO₄)₃ + 6KOH ⇒ 2Al(OH)₃ + 3K₂SO₄
Reactants Elements Products
2 Aluminum 2
3 Sulfur 3
18 Oxygen 18
6 Potassium 6
6 Hydrogen 6
Now the reaction is balanced. The coefficients are 1, 6, 2, 3.
In 1869, just five years after John Newlands put forward his law of octaves, a Russian chemist called Dmitri Mendeleev published a periodic table. Mendeleev also arranged the elements known at the time in order of relative atomic mass, but he did some other things that made his table much more successful.
i hope this helps in some way!
Answer:
when rutherford performed his experiment, only 1 in 20,000 alpha particles bounced straight back or were deflected greatly. the rest went straight through the gold foil. e) based on this evidence, what is in atom's center? positively charged particles.
