What does a model of the carbon cycle show?(1 point).
Answer:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to make Earth capable of sustaining life. It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks. Carbon sinks in the land and the ocean each currently take up about one-quarter of anthropogenic carbon emissions each year.

What general trend does electronegativity follow on the periodic table.
Answer:
As you go across the table and the periods get higher, the electronegativity increases. As you go down the periodic table by groups, the electronegativity decreases
Explanation:
Answer:
electronegativity decreases down a group and increases from left to right of the table
Explanation:
electronegativity shows how well an atom can attract electrons to itself in a covalent bond.
It is measured on the pauling scale, and the most electronegative element is fluorine.
electronegativity decreases down the group, because the increasing number of shells decreases the attraction between the nucleus and outermost electrons.
Electronegativity increases from left to right of a row, as across the row the number of protons in the nucleus increases. This allows a stronger attraction between outermost electrons and the nucleus.
So electronegativity increases up a group and across the row of the periodic table. Fluorine is the most electronegative element, measuring 4 on the pauling scale ( 4 is the highest number).

A 7. 5 kg block is attached to a horizontally-mounted spring with a spring constant of 750 j/m2. The block is released from rest with the spring extended by 15 cm from its normal length of 27 cm. The horizontal surface along which the block moves is frictionless. How long (in s) will it take this system to complete 2. 5 oscillations?.
It takes the system 1.58 s to complete 2.5 oscillations
Period of oscillationThe period of oscillation of the horizontally mounted spring is T = 2π√(m/k) where
m = mass of block = 7.5 kg and k = spring constant = 750 N/m²Substituting the values of the variables into the equation, we have
T = 2π√(m/k)
T = 2π√(7.5 kg/750 N/m²)
T = 2π√(0.01 kgN/m²)
T = 2π × 0.1 s
T = 0.2π s
T = 0.2 × 3.142
T = 0.6284 s
T ≅ 0.63 s
Time to complete 2.5 oscillationsSince one oscillation = period = 0.63 s, then 2.5 oscillations = 2.5 × 1 oscillation = 2.5 × 0.63 s
= 1.575 s

The value of the rate constant is : 0.63 * 10⁻²⁹ s⁻¹ and The unit of the rate constant is : sec⁻¹
The chemical reaction :
C₂H₅Cl ------> C₂H₄(g) + HCl(g)
Determine the value and unit of the rate constant ( K )let the rate of reaction be expressed as
R = k [ C₂H₅Cl ]ⁿ ---- ( 1 )
where : n = order
k = rate constant
From the table
2 = 2ⁿ
therefore n = 1
Hence we can rewrite equation ( 1 ) as
R = k [ C₂H₅Cl ] ¹ ( first order reaction ) ---- ( 2 )
Next step : substitute the value of C₂H₅Cl and initial rate into equation 2
0.630 * 10⁻³⁰ = k ( 0.1 ) ¹ M
Therefore : K = 0.630 * 10⁻²⁹ s⁻¹
Hence we can conclude that The value of the rate constant is : 0.63 * 10⁻²⁹ s⁻¹ and The unit of the rate constant is : sec⁻¹.
