Answer:2NaCl + 2H2O = 2NaOH + Cl2 + H2 this would be the correct balanced equation which the answer would be no
Explanation:When a current is passed through a solution of salt water, sodium chloride decomposes according to the following reaction: 2NaCl + 2H2O → 2NaOH + Cl2 + H2. What is the chemical symbol for the starting substance? A NaCl.Apr 14, 2018
<span>The extracellular fluid is high in NaCl so the cell would be dehydrated further and the two solutions would equilibrate. Ultimately water would leave the cell and passes to </span>extracellular fluid and equilibrium is reached.
Answer:
A) 2.27 grams of tungsten trioxide must be needed to prepare 1.80 g of tungsten.
B)To prepare 1.80 g of tungsten we will need 0.0587 grams of hydrogen gas.
Explanation:
A) Mass of tungsten prepared = 1.80 g
Moles of tungsten =
According to reaction, 1 mol of tungsten is obtained from 1 mole of tungsten trioxide.
Then 0.009783 moles of tungsten will be obtained from:
of tungsten trioxide
Mass of 0.009783 moles of tungsten trioxide :
0.009783 mol × 231.8 g/mol = 2.27 g
2.27 grams of tungsten trioxide must be needed to prepare 1.80 g of tungsten.
B) According to reaction,1 mol of tungsten is produced by 3 moles of hydrogen gas
Then 0.009783 moles of tungsten are produced by :
Mass of 0.02935 moles of hydrogen gas:
0.02935 mol × 2 g/mol =0.0587 g
To prepare 1.80 g of tungsten we will need 0.0587 grams of hydrogen gas.
Answer:
you an see the answer at the pic
Wat is considered a compound of hydrogen and oxygen and not a mixture because hydrogen and oxygen have gone through a chemical process to form the compound h2O. A mixture can generally be easily separated whereas a compound must undergo another chemical process to separate its elements. Therefore to separate oxygen and hydrogen from water a chemical process is necessary.
