1. Group: Groups shows the number of valence electrons and are shown in columns on the periodic table.
2. Period: Periods show the number of energy levels each element has and are shown in rows on the periodic table (up and down).
3. Blocks are show the amount of orbitals each element has. There is an s block, d block, p block, and f block.
Answer:
The specific gravity of the gel is 1470.68
Explanation:
Given:
Volume 
Diameter of tank 
m
Pressure at surface 
atm
Height 
ft 
m
Pressure at bottom is given by,
Where 
, 
Here volume is 4.24
m
From pascal equation,
Find density of gel from above equation,
So specific gravity is given by,
ζ = 
ζ = 
ζ = 
Therefore, the specific gravity of the gel is 1470.68
Answer:
The new pressure of the gas is 395.5mmHg
Explanation:
The pressure of a gas is inversely proportional to its concentration (Boyle's law). The equation that explain this law is:
P₁V₁ = P₂V₂
<em>Where P is pressure</em>
<em>And V is volume of 1, initial state and 2, final state of the gas</em>
<em />
Initial state:
791mmHg; 0.500L.
Final state:
1.00L
Replacing:
791mmHg* 0.500L = P₂*1.00L
P₂ = 395.5mmHg
<h3>The new pressure of the gas is 395.5mmHg</h3>
