1 mole of water = 18 grams (you can find this by finding mass of two hydrogen and one oxygen which is (1*2) + 16 = 18)
1.8 grams = 0.1 moles
1 H2O molecule has 10 electrons so 0.1 moles can be computed as:
(6.023*10^23)*(0.1)*10 = 6.023*10^23 electrons
Answer:
The mass of cryolite will be produced = 71247 g or, 71.247 kg
Explanation:
The balanced chemical equation for the synthesis of cryolite
Al₂O₃(s) + 6 NaOH(l) + 12 HF(g) → 2 Na₃AlF₆ + 9 H₂O(g)
Answer:
It reflects light from one mirror to the second mirror so the second mirror reflects both the light and the image to the users eye.
Explanation:
Answer:
Dissociation
Explanation:
The molecule of water is polar. This means that the hydrogen has a partial positive charge while the oxygen has a partial negative charge.
Ionic compounds have equal number of positive and negative charges.
When these compounds are placed in water, the partial positive hydrogen starts to attract the negative ion of the ionic compound while the partial negative oxygen starts to attract the positive ion of the ionic compound.
This process is called dissociation and leads to the breaking of ionic compound into cations and anions in water.
Hope this helps :)
