Answer: (see explanation part)

Explanation:

A piece of solid material of specific heat c unknown is weighed with a balance, m resulting in its mass. The piece is put in almost boiling water at temperature T.

M grams of water are put on the calorimeter, it is stirred and after a short time, its temperature T0 is measured.

The solid part is quickly deposited in the calorimeter. It is stirred, and after a certain time the equilibrium temperature Te is reached.

The data is recorded and c is cleared of the formula that's attached (please take a look).

My only guess is obtain a metal and heat it in a boiling water bath (of known temperature) this will be your initial temperature. Now obtain a calorimeter cup with water of known temperature as well. Place the metal into the calorimeter cup and record the temperature after 5 minutes. You now have delta T, mass of the metal, and Q. Solve for C.

Hope this helps xox :)

Kinetic energy is the energy possessed by an object due to its motion. If an object is moving, then it has kinetic energy. If an object has kinetic energy, then it is moving. Many students confuse kinetic energy with potential energy.

In the following reaction, how many moles of CO2 will form if 10 moles of C3H4 are reacted? How many moles of O2 will also be co

umka2103 [35]

Answer:

40 moles of O₂

30 moles of CO₂

Explanation:

Given parameters:

Number of moles of C₃H₄ = 10moles

Unknown:

Number of moles of CO₂ = ?

Solution:

The number of moles helps to understand and make quantitative measurements involving chemical reactions.

We start by solving this sort of problem by ensuring that the given equation is properly balanced;

C₃H₄ + 4O₂ → 3CO₂ + 2H₂O

We can clearly see that all the atoms are conserved.

Now, we work from the known to unknown. We know the number of moles of C₃H₄ to be 10moles;

1 mole of C₃H₄ reacted with 4 moles of O₂

10 moles of C₃H₄ will react with 10 x 4 = 40moles of O₂

1 mole of C₃H₄ will produce 3 moles of CO₂

10 moles of C₃H₄ will produce 10 x 3 = 30moles of CO₂
