Answer:

In a swimming pool chlorine ion are mix with water, a polar molecule. In this case the pool is a perfect environment for the conductive solution. The reason why, people can be electrocuted is that the hypochlorite is an ion and in the water, it form an ionic compound.

Answer:

0.305 mol

Explanation:

Ca(NO) is not a molecule. I think you meant to type Ca(NO3)2, which is calcium nitrate.

The moles of a compound is equal to is mass divided by its molar mass.

The molar mass of Ca(NO3)2 is 164.09 g/mol.

50.0 / 164.09 = 0.305

2S+3O2=2SO3. If 4moles of sulfur reacts with 9. 5 moles of oxygen, how many moles of oxygen would remain after the reaction?

natali 33 [55]

Answer: 3.5 moles

Explanation:

For every 2 moles of sulfur consumed, there are 3 moles of oxygen consumed.

This means that sulfur is the limiting reactant, meaning that 2(3)=6 moles of oxygen will be consumed.

Thus, 9.5-6=3.5 moles of oxygen will remain.

A volume of 25cm3 of a carbonate solution of concentration 0.2mol dm-3 was neutralized by 20 cm3 of acid of concentration 0.5 mo

Galina-37 [17]

Answer: 1 mol of carbonate to 2 mol of acid

Explanation:

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution in ml}}$

a) $\text{Moles of carbonate}=\frac{0.2moldm^{-3}\times 25cm^3}{1000}=0.005mol$

b) $\text{Moles of acid}=\frac{0.5moldm^{-3}\times 20cm^3}{1000}=0.01mol$

Thus the mole ratio of carbonate to acid is = $\frac{0.005}{0.01}=\frac{1}{2}$

It is difficult to press the football in water why?

Sati [7]

Answer:

The ball you want to submerge displaces the water occupied in the ball's volume. ... In water the concrete has a buoyancy pressure force equal to the displaced liquid's weight and weighs only 120 pounds until it reaches the surface.
