Answer:
Molarity of HCl solution = 0.25 M
Explanation:
Given data:
Volume of NaOH= V₁ = 25.0 mL (25/1000 = 0.025 L)
Molarity of NaOH solution=M₁ = 0.185 M
Volume of HCl solution = V₂ = 0.0200 L
Molarity of HCl solution = M₂= ?
Solution:
M₁V₁ = M₂V₂
0.185 M ×0.025 L = M₂ × 0.0200 L
M₂ = 0.185 M ×0.025 L / 0.0200 L
M₂ = 0.005M.L /0.0200 L
M₂ = 0.25 M
melting point because the melting point is the heat required to make an object melt anything less than this poitn will not make the substence melt.
Answer:Referring to the fact that a neuron either fires completely or does not fire at all.
Explanation:
Answer:
55.75g
Explanation:
From
m/M = CV
Where
m= required mass of solute
M= molar mass of solute
C= concentration of solution
V= volume of solution=675ml
Molar mass of solute= 3(23) + 31 + 4(16)= 69+31+64=164gmol-1
Number of moles of sodium ions present= 1.5× 675/1000= 1.01 moles
Since 1 mole of Na3PO4 contains 3 moles of Na+
It implies that 1.01/3 moles of Na3PO4 are present in solution= 0.34moles
mass of Na3PO4= number of moles × molar mass= 0.34 × 164 =55.75g
Answer:
<u>C. The answers depend on people's opinions, not on observations.</u>
Explanation:
Morals are what people <em>think</em> is the right or wrong behavior and the <em>goodness</em> or <em>badness</em> of a character.
Ethics are <em><u>morals</u></em> that <em><u>govern</u></em> a person.
So the answer is C because these answers cannot be seen from the outside.
For example: A PERSONALITY TRAIT is something you can't really see. A PHYSICAL TRAIT is something you <em>can</em> see.
Ethics and morals are like personality traits.
