Answer:
carbon dioxide concentration goes down, temperature goes down. Carbon dioxide goes up temp goes up, carbon dioxide is directly related to temperature by insulating it in the earths atmosphere and if there's less of it then the temp would go down.
Explanation:
Answer:
Tangible
Explanation:
Tangible alone means it is "perceptible by touch," meaning you physically observe the object with your sense of touch.
Having tangible motivation is like working for money or a trophy.
ANSWER:
A proton has a "positive charge" and is found in the nucleus.
goodluck!!
support me by marking as brainliest!! :)
The correct answer is option 2. A 0.8 M aqueous solution of NaCl has a higher boiling point and a lower freezing point than a 0.1 M aqueous solution of NaCl. This is explained by the colligative properties of solutions. For the two properties mentioned, the equation for the calculation of the depression and the elevation is expressed as: ΔT = -Km and <span>ΔT = Km, respectively. As we can see, concentration and the change in the property has a direct relationship.</span>

Answer:
The concentration of that should used originally is
Explanation:
From the question we are told that
The necessary elementary step is
The time taken for sixth of 0.5 M of reactant to react
The time available is
The desired concentration to remain
Let Z be the reactant , Y be the first product and X the second product
Generally the elementary rate law is mathematically as
Where k is the rate constant , is the concentration of Z
From the elementary rate law we see that the reaction is second order (This because the concentration of the reactant is raised to power 2 )
For second order reaction
Where is the initial concentration of Z which a value of
From the question we are told that it take 9 hours for the concentration of the reactant to become
So
=>
For
