For example, monosaccharides:
C₆H₁₂O₆
aldohexoses
ketohexoses
C₃H₆O₃
aldotrioses
ketotrioses
and many others
At STP, copper (Cu) would be the only substance here that will exist in the solid state.
Answer:
the answer is 4 because 3 just have d orbitals
Benzene reacts with O₂ to produce CO₂ and H₂O, i.e.
C₆H₆ + 7.5 O₂ → 6 CO₂ + 3 H₂O
According to equation,
78.11 g (1 mole) C₆H₆ reacts to produce = 264 g (6 moles) of CO₂
Hence,
7.80 g C₆H₆ when reacted will produce = X g of CO₂
Solving for X,
X = (7.80 g × 264 g) ÷ 78.11 g
X = 26.36 g of CO₂
Theoretical Yield:
26.36 g of CO₂ produced is theoretical yield which shows 100% reaction between benzene and oxygen.
Actual Yield:
According to statement the actual amount of CO₂ produced is 3.0 g of CO₂.
%age Yield:
%age Yield = (Actual Yield ÷ Theoretical Yield) × 100
Putting Values,
%age Yield = (3.00 g ÷ 26.36 g) × 100
%age Yield = 11.38 %
Answer:
P₂ = 647 torr
Explanation:
Given data:
Initial pressure = 565 torr
Initial temperature = 27°C
Final temperature = 71°C
Final pressure = ?
Solution:
Initial temperature = 27°C (27+273 = 300 K)
Final temperature = 71°C (71+273 = 344 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
565 torr / 300K = P₂/344 K
P₂ = 565 torr × 344 K / 300 K
P₂ = 194360 torr. K /293 K
P₂ = 647 torr
