They collect all the evidence for cases
Solution,
Mass of Mg - 21gm
molar mass of Mg - 24gm
moles = Given mass/ Molar mass
moles = 21/24 = 0.875
1 mole of Mg produce 1 mole of H2 gas
so 0.875 mole of Mg will produce 0.875 moles of H2 gas
One mole of H2 gas = 22.4 litre
0.875 mole of H2 gas = 0.875×22.4
0.875 mole of H2 gas = 19.60 litre
So the nearest ANSWER is Option four 19.37 litre.
The tire pressure is the sum of gauge pressure and the standard pressure of atmospheric pressure
We know that the standard air pressure of surrounding = 101.325 kPa
The given gauge pressure = 413 kPascal
So the tire pressure = 101.325 kPa + 413 = 514.325 K Pa
We can also convert the given pascals to atmosphere or Torr or mmHg or bar
Answer:
mixture
Explanation:
A mixture is something that can be separated, while a compound is something that can be separated (unless by chemicals).
An example of a mixture would be trail mix. You can separate the components without using chemicals.

Answer:
For carbon the most important forms of hybridization are the sp2- and sp3- hybridization. Besides these structures there are more possiblities to mix dif- ferent molecular orbitals to a hybrid orbital. An important one is the sp- hybridization, where one s- and one p-orbital are mixed together.
