A sample of lead with a mass of 54.3 g is heated to a temperature of 384.4 K and placed in a container of water at 291.2 K. The

final temperature of the lead and water is 297.6 K. Assuming no heat loss, what mass of water was in the container?

The mass of the water in the container given the data from the question is 22.5 g

<h3>Data obtained from the question</h3>
  • Mass of cold lead (M) = 54.3 g
  • Temperature of lead (T) = 384.4 K
  • Temperature of water (Tᵥᵥ) = 291.2 K
  • Equilibrium temperature (Tₑ) = 297.6 K
  • Specific heat capacity of the water (Cᵥᵥ) = 4.184 J/gK
  • Specific heat capacity of lead (C) = 0.128 J/gK
  • Mass of water (Mᵥᵥ) = ?

<h3>How to determine the mass of water </h3>

Heat loss = Heat gain

MC(T – Tₑ) = MᵥᵥCᵥᵥ(Tₑ – Tᵥᵥ)

54.3 × 0.128 (384.4 – 297.6) = Mᵥᵥ × 4.184(297.6 – 291.2)

6.9504 × 86.8 = Mᵥᵥ × 4.184 × 6.4

Divide both side by 4.184 × 6.4

Mᵥᵥ = (6.9504 × 86.8) / (4.184 × 6.4)

Mᵥᵥ = 22.5 g

Balance the combustion eqation; __C5H + __O2 ---&gt; __CO2+__H2O
stira [4]
This equation C5H + O2 ---> CO2 + H2O has a mistake.

C5H is wrong. You missed the subscript of H.

I will do it for you assuming some subscript to show you the procedure, but you have to use the right equation to get the right balanced equation.

Assuming the tha combustion equation is C5H12 + O2 ---> CO2 + H2O

First you need to  balance C, so you put a 5 before CO2 and get

C5H12 + O2 ---> 5CO2 + H2O

Now you count the hydrogens: 12 on the left and 2 on the right. So put a 6 before H2O and get:

C5H12 + O2 ---> 5CO2 + 6H2O

Now count the oxygens: 2 on the left and 16 on the right, so put an 8 on before O2:

=> C5H12 + 8O2 ---> 5CO2 + 6H2O.

You can verify that the equation is balanced

Using two different instruments I measured the length of my foot to be 27 centimeters and 27.00 centimeters. Explain the differe
Sophie [7]

Answer:

As you used two diferent instruments, one is more sensitive than the other.

Explanation:

The sensitivity of an instrument is the minimum amount of magnitude that can be  differentiate a measurement system.

In method A, you got 27 cm, so if in method B, you got 27.00, method B is more sensitive. It's like saying that one system measures more than the other
