Answer:
23.60 mL NaOH
Explanation:
The reaction is CH3COOH + OH- --> CH3COO+ + H2O
Since the reaction is one-to-one, we can use M1V1 = M2V2.
M1 = 0.1894 M CH3COOH
V1 = 25.00 mL CH3COOH
M2 = 0.2006 M NaOH
V2 = ?
Solve for V2 --> V2 = M1V1/M2
V2 = (0.1894 M)(25.00 mL) / (0.2006 M) = 23.60 mL NaOH
Well knowing that a representative particle is the smallest unit that would mean an iron atom would be the answer
Answer:
When a body moves in a circle with constant speed , it is said to be in uniform circular motion .
Explanation:
- When an object moves in a circular path , its direction changes at each point .
- This change in direction result in change of velocity (velocity is vector quantity which changes if direction of the object change) .However speed do not change (it is scalar quantity , not affected by Direction)
- The Change in velocity produce acceleration ( a = v - u)
- Hence The object always produce acceleration in uniform circular motion .So, Some force (centripetal force) is needed to keep the object in circular motion.
Metals are located on the left of the periodic table, and nonmetals are located on the upper right.
Explanation: Metals: Lustrous (shiny)
Good conductors of heat and electricity.
High melting point.
High density (heavy for their size)
Malleable (can be hammered)
Ductile (can be drawn into wires)
Usually solid at room temperature (an exception is mercury)
Opaque as a thin sheet (can't see through metals)
Nonmetals: High ionization energies.
High electronegativities.
Poor thermal conductors.
Poor electrical conductors.
Brittle solids—not malleable or ductile.
Little or no metallic luster.
Gain electrons easily.
Dull, not metallic-shiny, although they may be colorful
