Answer:
yeyeye
Explanation:
hi and bye no problem you will come and die
Alkali are soluble bases, however not all bases are soluble in water, therefore not all bases are Alkali.
<span>1. the pressure of a gas over a solvent is increase
</span> Gas solubility decreases"<span>
2. the partial pressure of an anesthetic gas is increased
</span> " gas solubility does not change"<span>
3. air in blood a diver descends 10 M and pressure increases by 1 atm
</span> Gas solubility decreases"<span>
4. the temp is increase
</span>"gas solubility increases"<span>
5. O2 the temp of a body of water rises.
</span>"gas solubility increases"
Answer:
0.508 mole
Explanation:
NOTE: Since no hydrogen is attached to the compound given in question above, it means the compound is CCl₄.
The number of mole present in 78.2 g of CCl₄ can be obtained as follow:
Mass of CCl₄ = 78.2 g
Molar mass of CCl₄ = 12 + (35.5×4)
= 12 + 142
= 154 g/mol
Mole of CCl₄ =?
Mole = mass / molar mass
Mole of CCl₄ = 78.2 / 154
Mole of CCl₄ = 0.508 mole
Therefore, 0.508 mole is present in 78.2 g of CCl₄
