A Non Contact Force is a force which acts on an object without coming physically in contact with it.[1] The most familiar example of a non-contact force is gravity, which confers weight.[1] In contrast a contact force is a force applied to a body by another body that is in contact with it.[1]
A chemical bond is the best classification.
Let's write the balanced chemical reaction for this:
K₂CrO₄ + Pb(CH₃COO)₂ --> PbCrO₄ + 2 CH₃COOK
The products are lead(ii) chromate and potassium acetate. As you can notice, there is an exchange of ions involved for both reactants. This type ofreaction is called the <em>double-replacement reaction or also called metathesis</em>.
Answer:
0.77 M
Explanation:
Molarity is the concentration of a solution per liter
C= concentration
n= number of moles
V= volume of solution
The formula we will use is C= n/V
C= n/V
C= (1.93 mol NaCl)/(2.5 L of solution)
C= 0.772 mol/L
Since this concentration is given in moles per liters of a solution, this concentration is also the molarity.
C= 0.772 mol/L
*Include two significant digits in final answer*
M= 0.77 M
Answer:
anaphase
Explanation:
because the chromosomes are moving towards different poles
