Answer:
In numerical order left to right, they are arranged by the number of protons in the nucleus of a single atom of each element
Answer:
First, the lining may consist of loose, smaller bits of the same materials that have been incorporated into the latticework of the nest. These finer materials are utilized to shed water, deter pests, conceal the eggs from predators, insulate, and cushion them. ... They also serve to insulate and cushion the eggs.
Explanation:
So first, you would take 10 and raise it up to the 14th power. Then take 10, and raise it up to 10th power. After doing all the work, your answer should be 2.336E29.
Answer:
C.
Milk boils at about 212°F (100°C).
Explanation:
The boiling point is a physical property of every matter. Physical properties tell us what a substance is when no change is occuring to its constituents. Such properties can be observed with our senses or instruments or pieces of apparatus.
Some examples of physical properties are colour, taste, odour, hardness, texture, solubility in water.
They all depict what typifies a matter when no change whatever is imparted on them.
Answer:
pt1
The half-life of the element is 1,600 years.
pt2
k = ln(2)/(t1/2) = 0.693/(t1/2).
Where, k is the rate constant of the reaction.
t1/2 is the half-life of the reaction.
∴ k =0.693/(t1/2) = 0.693/(1,600 years) = 4.33 x 10⁻⁴ year⁻¹.
kt = ln([A₀]/[A]),
where, k is the rate constant of the reaction (k = 4.33 x 10⁻⁴ year⁻¹).
t is the time of the reaction (t = ??? year).
[A₀] is the initial concentration of the sample ([A₀] = 312.0 g).
[A] is the remaining concentration of the sample ([A] = 9.75 g).
∴ t = (1/k) ln([A₀]/[A]) = (1/4.33 x 10⁻⁴ year⁻¹) ln(312.0 g/9.75 g) = [8,000 year].
