Answer:
Philosophy may be called the "science of sciences" probably in the sense that it is, in effect, the self-awareness of the sciences and the source from which all the sciences draw their world-view and methodological principles, which in the course of centuries have been honed down into concise forms.
Explanation:
Answer:
a partial negative charge
Explanation:
The oxygen on water molecules carries a partial negative charge on it. Water is made up of oxygen and hydrogen bonded via polar covalent bonds.
This bond involves the attraction between two atoms that shares their valence electrons in covalent bonding. The oxygen atom is more electronegative with more affinity for the shared electron. This suggests that it will pull the shared electrons more closer than the hydrogen atom.
This pull due to electronegativity difference leaves a partial negative charge on oxygen and a partial positive charge on hydrogen.
Answer:
V₂ = 453.125 mL
Explanation:
Given data:
Initial volume = 25.0 mL
Initial molarity = 1.45 M
Final molarity = 0.0800 M
Final volume = ?
Solution:
Formula:
M₁V₁ = M₂V₂
Now we will put the values in formula.
1.45 M × 25.0 mL = 0.0800 M × V₂
V₂ = 1.45 M × 25.0 mL / 0.0800 M
V₂ = 36.25 M.mL / 0.0800 M
V₂ = 453.125 mL
The freezing point is the temperature at which things freeze.
