The answer for dry sample of carbon dioxide is upwards into a gas jar
Answer:
ICE Table Figure
a. 67.37 g 
b. 35.62 g 
c. 58.61 g
Explanation:
For the <u>ICE table </u>we have to keep in mind that we have 4 moles of and 1 mol of 
and the reactives are consumed, so for we will have -4X and for we will have -X. Follow the same logic we will have -4X for .
a. <u>Mass of the product</u>
Molar mass of = 256.52 g/mol
Molar mass of =70.9 g/mol
Molar mass of =135.03 g/mol
We have to find the limiting reagent in the reaction:
Divide by the coefficients in the balanced reaction:
The limiting reagent would be
Now is posible to calculate the amount of produced:
b. <u>Mass in excess</u>
C. <u>87%Yield</u>
When equal volumes of ethanol and water are mixed to form a solution, the entropy of the resulting solution increases. This is because ethanol and water are both polar substances, making them miscible. The solubility of both substances is high because they have similar attractions due to the presence of hydrogen bonding. This means that molecules of water and ethanol freely move with each other, therefore increasing the dispersal, randomness, and disorder (entropy) of the system.
The element X is titanium.
According to the question, the percentage by mass of Cl in XCl4 is 75.0%.
The percentage by mass is obtained from;
Mass of element in the compound/molar mass of compound * 100
Hence;
Let the mass of the unknown element be X
75 = 142/X + 142 * 100
75 (X + 142) = 142 * 100
75X + 10650 = 14200
75X = 14200 - 10650
X = 14200 - 10650/75
X = 47
Hence, X is titanium.
