Answer:
Aluminum
Explanation:
Given
<em>See attachment for chart</em>
Required
Identify the unknown substance
To do this, we simply calculate the specific heat capacity from the given parameters using:
This gives:
So, we have:
From the attached chart, we have:
--- The specific heat capacity of Aluminum
<em>Hence, the unknown substance is Aluminum</em>
Answer:
8.68 L is the new volume
Explanation:
You use Boyle's law for this.
= first pressure
= second pressure
= first volume
= second volume
Convert pressure from atm to mmHg (use same units):
5.97 x 760 = 4537.2 -> 4.54 x 10³
...maintain 3 significant figures in calculation, and round as needed...
(4.54 x 10³ mmHg)(2.79 L) = (1460 mmHg)()
(4.54 x 10³ mmHg)(2.79 L) / (1460 mmHg) = = 8.68 L
Hope this helps :)
This equation C5H + O2 ---> CO2 + H2O has a mistake.
C5H is wrong. You missed the subscript of H.
I will do it for you assuming some subscript to show you the procedure, but you have to use the right equation to get the right balanced equation.
Assuming the tha combustion equation is C5H12 + O2 ---> CO2 + H2O
First you need to balance C, so you put a 5 before CO2 and get
C5H12 + O2 ---> 5CO2 + H2O
Now you count the hydrogens: 12 on the left and 2 on the right. So put a 6 before H2O and get:
C5H12 + O2 ---> 5CO2 + 6H2O
Now count the oxygens: 2 on the left and 16 on the right, so put an 8 on before O2:
=> C5H12 + 8O2 ---> 5CO2 + 6H2O.
You can verify that the equation is balanced
Two hydrogen and two oxygen multiply for two
Answer:
The rule is especially applicable to carbon, nitrogen, oxygen, and the halogens, but also to metals such as sodium or magnesium. ... All four of these electrons are counted in both the carbon octet and the oxygen octet, so that both atoms are considered to obey the octet rule.
