What would happen if this cell were moved from pure water to a seawater solution?

<span>The cell would swell and burst, because the 20% salt solution is hypotonic with respect to the cell, causing a net movement of water into the cell. Example, water moves from the blood filtrate that will form urine. The same will do while pure water moved to seawater.</span>

For changing potential energy; When you drop a book, gravitational potential energy is transformed into kinetic energy. Your car transforms the chemical potential energy stored in gasoline into the kinetic energy of the car's motion.

For Kinetic Energy; kinetic energy can be converted into electrical energy by a generator or into thermal energy by the brakes on a car.

Gaseous ammonia chemically reacts with oxygen O2 gas to produce nitrogen monoxide gas and water vapor. Calculate the moles of ox
WINSTONCH [101]

Answer : The number of moles of oxygen needed are, 1.5 moles.

Explanation :

The balanced chemical reaction will be:

4NH_3+5O_2\rightarrow 4NO+6H_2O

Now we have to calculate the moles of oxygen.

From the balanced chemical reaction we conclude that,

As, 6 moles of water vapor produces from 5 moles of oxygen

So, 1.80 moles of water vapor produces from \frac{5}{6}\times 1.80=1.5 moles of oxygen

Therefore, the number of moles of oxygen needed are, 1.5 moles.

6. If 4 mole of the rocket fuel ammonium perchlorate, NH4C/04 (s) is
Bond [772]

Answer:

144g of H₂O

Explanation:

3NH₄ClO₄(s) + 3Al → Al₂O₃(s) + AlCl₃(s) + 3NO(g) + 6H₂O(g)

From the equation:

3 moles of NH₄ClO₄ produced 6 moles of H₂O

4 moles of NH₄ClO₄ produced ? moles of H₂O

(4 ₓ 6)/3 = \frac{24}{3} = 8 moles of H₂O

1 mole of H₂O = (1 × 2) + 16 = 18g (The Relative Molecular mass of H₂O)

8 moles of H₂O = ?

Therefore 8 × 18 = 144g

=144g of H₂O
