Answer:
1)A period in the periodic table is a horizontal row. All elements in a row have the same number of electron shells. ... Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases both as you move down a group or across a period.
2)D)Na has one fewer valence electron than Ca.
Answer:
1072 torr
Explanation:
To answer this problem we can use <em>Gay-Lussac's law</em>, which states:
Now we convert the given temperatures into K:
- T₁ = 15°C ⇒ 15+273.16 = 288.16 K
- T₂ = 36°C ⇒ 36+273.16 = 309.16 K
We <u>input the data</u>:
- 1000 torr * 309.16 K = P₂ * 288.16 K
And <u>solve for P₂</u>:
Answer:
Comvection
Explanation:
The movement causes the density to rise and therefore transfer more heat
Answer:
D) 1/2
Explanation:
Using Ideal gas equation for same mole of gas as
Given,
P₂ = 4P₁
T₂ = 2T₁
Using above equation as:
<u>The volume change by half of the original.</u>
