132 g of C , 22 g of H , 176 g of O
132 + 22 + 176 => 330 g <span>of the substance
</span>Now convert the masses in <span>moles :
</span>
C = 12.0 u H = 1.0 u O = 16.0 u
C = 132 / 12.0 => 11 moles
H = 22 / 1.0 => 22 moles
O = 176 / 16.0 => 11 moles
Using the values obtained the lowest proportion in mols of elements present, simply divide the values found for the least of them<span>:
</span>
C = 11 / 11 => 1
H = 22 / 11 => 2
O = 11 / 11 => 1
formula empirically <span>is : CH</span>₂O
hope this helps!
Answer:
0.7atm
Explanation:
Given parameters:
Initial temperature = 25.2°C in Kelvin; 25.2 + 273 = 298.2K
Initial pressure = 0.6atm
Final temperature = 72.4°C in kelvin = 72.4 + 273 = 345.4K
Unknown:
Final pressure = ?
Solution:
Since we are dealing with pressure temperature relationships under a fixed volume, we use a simplification of the combined gas law to solve this problem.
At fixed volume;
where P and T are temperature values
1 and 2 are the initial and final states
Input the parameters and solve for P₂
P₂ = 0.7atm
The original change is chemical, affecting the main colorant because of temperature. Paint, is a surface change, not changing anything about the leaf itself, but showing a different color to your eye.
Iconic compound consists of equal number of positive and negative ions so the charge of icon compound is zero.
