Explanation:
took test :D
Answer:
The answer will result in one significant digit.
Explanation:
1. Subtract:
12.1 - 12.004 = 0.096
2. ROund to the correct number of significant digits:
For addition and subtraction we round the sum or the difference to the least number of digits after the decimal point there are in the problem.
For example, SInce 12.1 has one number after the decimal point and 12.004 has three numbers after the decimal point, we round the answer to one number after the decimal point because 12.1 is the number in the problem which has the least amount of digits after the decimal point.
We round 0.096 to 0.1.
0.1 has one significant digit.
Answer: Mass of the condensed vapor is 21.35 grams.
Explanation: As a gas, the Ideal Gas Law can be used to determine how many mols there are in the flask on the conditions described in question.
Temperature in K: 273 + 99.3 = 372.4K
Pressure in mmHg: P = 760.5 mmHg
Volume in L: V = 496.3.
= 0.5 L
Universal Constant of Gases in mmHg: R = 62.36 L.mmHg.K⁻¹.mol⁻¹
PV = nRT
n = 
n = 
n = 0.1625
To determine the mass in grams:
n = 
m = nM
m = 0.1625.131.4
m = 21.35
On the conditions cited above, there are <u>21.35 grams</u> of the unknown condensed vapor
Just times the amount of electrons in one copper atom by 4
The amount of the product in grams, formed from the limiting reactant is the theoretical yield
<u>Explanation:</u>
In a chemical reaction when the limiting agent is completely reacted and the product obtained is termed as Theoretical yield. The amount of product yield that is attained through a complete reaction of the limiting agent is the theoretical yield. Grams or moles is used for expressing theoretical yield.
This is calculated form the limiting agent in a complete chemical reaction which is balanced. If a chemical reaction is unbalanced, it should be first balanced to find the theoretical yield. Then, the limiting agent must be found. When the limiting agent is small in quantity, the reaction cannot be completed once the limiting agent is fully used and exhausted.
