Every force has a strength and a direction. This is because force is a vector quantity
Answer:
Explanation:
First we need to find how many moles of ammonium weigh 62 grams.
Molar mass of NH4 = (14.0)+(4*1.0) grams
or 18.0 grams/mole
62 (g)/18(g/mole) = 3.444... moles of NH4
If it is dissolved in 5 litres of water, the concentration will be 3.444moles/5L
or 0.6888 M.
Answer:
Anaphase
Explanation:
<em>The centromere splits during the anaphase of the cell division. Thus, allowing the two linked chromatids to separate.</em>
A typical chromosome is made up of two sister chromatids joined together by a structure known as the centromere. During cell division - at the metaphase stage - the chromosomes align at the equator of the cell, forming the metaphase plate. The spindle from the opposing ends of the cell engages each chromosome at the kinetochore of the centromere.
<u>At the anaphase stage</u><u>, the centromere splits, leading to the separation of the sister chromatids of each chromosome. The sister chromatids of the same then start migrating in the opposite direction as a result of the shortening of the spindle fiber.</u>
Explanation:
Half life = 129s
Initial Concentration = 0.527M
Rate constant = ?
Order of reaction = ?
The half-life equation of a first-order reaction does not include a reactant concentration term. A half-life is independent of concentration and remains constant throughout the duration of the reaction.
Order of reaction = First Order
t1/2 = 0.693 / k; where k = rate constant
129 = 0.693 / k
k = 0.693 / 129 = 0.00537s-1
