Answer:

19.7 g of CaCl₂ are produced

Explanation:

This is the reaction:

CaCO₃ + 2HCl →  CaCl₂  +  CO₂  +  H₂O

As we have the mass of reactants, we should determine the moles we used, of each

29g . 1mol / 10.08 g = 0.289 moles

13 g . 1mol / 36.45 g = 0.356 moles

Ratio is 1:2, so If I have 1 mol of carbonate I need the doulbe of hydrochloric. Certainly the limiting reactant is the HCl.

I have 0.289 moles of salt and I need 0.578 (x2) moles of acid. - I only have 0.356 moles.

As we found out the limiting reactant we can work with the reaction. Ratio with CaCl₂ is 2:1 so,

2 moles of HCl produce 1 mol of CaCl₂

Then, 0.356 moles of HCl would produce (0.356 . 1) / 2 = 0.178 moles.

To convert the moles to mass we do: 0.178 mol . 110.98 g / 1mol = 19.7 g

State 2 postulates of kinetic theory of gases of 45 of 450
Ber [7]

Explanation:

The kinetic theory of gases is basically used to explain the behavior of gases.

Some of the assumptions of the theory is as follow:

  • A gas is composed of large number of identical molecules at different speeds.
  • The space occupied by the gas molecules themselves are negligible compared to the volume of the space they occupy.
  • The molecules are independent of each other and the force of attraction and repulsion between them are negligible.
  • The molecules collide elastically with one another and with the walls of the container.
  • The temperature of gas is a measure of their average kinetic energy.

As you have seen in this lab, the density of water is near 1 g/cm3. Anything with a density lower than this will float in water,
hammer [34]
The third answer is the one you want. You have to have an adjustable density. All other things being equal, if the tanks you use for holding just water when filled with water will let the sub sink, because the sub is made of a dense metal like iron or steel.

If on the other hand you fill these tanks with air, the net density will be below one and the sub will rise.
