Answer:
B or C
Explanation:
I don't really know sorry.
Answer:
Hence , in a century<u> 0.342 liters</u> of the liquid will drip.
Explanation:
The rate of the flow of the liquid droplet is given by:


<u>Unit conversion:</u>
We need to change mL/hr into Liter/century
1 L = 1000 mL (given)
1 mL = 0.001 L......(1)
1 century = 100 year
1 year = 365 days
So, 1 century = 100 x 365 days = 36500 days
1 day = 24 hrs
So , 36500 days = 36500 x 24 hr = 876000 hr
Hence ,
1 century = 36500 days = 876000 hr
we are not asked to calculate the answer in days
1 century = 876000 hr
1 hr = 1/ 876000 century
.....(2)
From (1) and (2) put the value in the given formula:
This is for 1 mL/hr to 1 L/century
Now for 300 mL/hr . the rate will be more , multiply the answer by 300
Rate = 0.342 Liters / century
Hence , in a century 0.342 liters of the liquid will drip.
Balance Chemical equation is,
P₄ + 10 Cl₂ → 4 PCl₅
According to Balance Equation,
123.89 g (1 mole) of P₄ reacts to produce = 4 Moles of PCl₅
Then,
23 g of P₄ will react with excess Cl₂ to produce = X moles of PCl₅
Solving for X,
X = (4 mol × 23 g) ÷ 123.89 g
X = 0.742 g of PCl₅
Result:
When 23 g of P₄ is reacted with excess Cl₂, 0.742 g of PCl₅ is produced.
Answer:
The number of moles of benzaldehyde = 0.0253 moles
Explanation:
The molecular formula of benzaldehyde is C₇H₆O
Its molecular mass is calculated from the atomic masses of the constituent atoms.
C = 12.0 g: H = 1.0 g; O = 16.0 g
Molecular mass = ( 12 * 7) + (1 * 6) + (16 * 1) = 106.0 g/mol
Number of moles of substance = mass of substance/ molar mass of the substance
mass of benzaldehyde = 2.68; molar mass = 106.0 g/mol
Number of moles of benzaldehyde = 2.68 g/ 106 g/mol = 0.0253 moles
Therefore, the number of moles of benzaldehyde = 0.0253 moles
