<u>Answer:</u> The molecular formula of compound is
<u>Explanation:</u>
We are given:
Empirical formula of compound = CHO
For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.
The equation used to calculate the valency is :
We are given:
Mass of molecular formula = 180 g/mol
Mass of empirical formula = 29 g/mol
Putting values in above equation, we get:
Multiplying this valency by the subscript of every element of empirical formula, we get:
Hence, the molecular formula of compound is
First we need to find the limiting reactant. This is the reactant that is theoretically consumed completely first. Theoretical yield is how much product is produced given the limiting reactant is consumed and the percent yield is the fraction of the actual products produced and the theoretical products produced.
The limiting reactant is <span>Pb(<span>C2</span><span>H3</span><span>O2</span><span>)2.
The theoretical yield is </span></span>1.2373008g and you should get the Percent yield which is Actual yield/theoretical yield. <span />
A covalent bond is formed.
Phytoplankton, a specific type of microscopic producer, supplies up to 50% of Earth's oxygen.
Initial Conditions:
Volume=v1= 3.5 L
Temperature= T1 =298K
Final Conditions:
Temperature= T2= 285K
Volume= v2= ?
Use the general gas equation;
P1*v1/T1 = P2*v2/T2
Note:
Pressure is constant
so the equation become,
v1/T1 = v2/T2
3.5/298 = v2/285
v2 = 3.347 L
