Answer:

d. atmosphere, biosphere, and geosphere

Explanation:

Carbon is one of the most common elements on the planet, with large reservoirs in the biosphere, atmosphere, geosphere and hydrosphere in the form of carbohydrates, proteins, nucleic acids, carbon dioxide and calcium carbonate. Events such as plant cultivation, wood burning and decomposition of living matter prove that carbon is in the above mentioned environments simultaneously as these events are the result of adding to the carbon removal from these environments.

With its strong influence on the interaction between molecules, the carbon cycle is a fundamental process for maintaining life on earth. Responsible for photosynthesis and keeping the planet warm through the greenhouse effect, without it we would not be here.

Using de Broglie's equation, λ = h/mv which would have a larger wavelength, a slow-moving proton or a fast-moving golf ball? Exp
tatuchka [14]

Answer: Proton will have larger wavelength

Explanation:

\lambda =\frac{h}{mv}  (de-Broglie's equation)

\lambda =\text{wavelenght of the particle}

h= Planck constant

m= mass of the particle

v= velocity of the particle

As we can see from the de-Broglie's equation , that wavelength is inversely proportional to the product of mass into velocity of the object.

The wavelength of proton will be higher than that fast moving golf ball because mass of proton (1.67 \times 10^{-24}g) is very small than that of the golf ball (45.93 g). Proton is moving  at slow velocity and the golf ball is moving with fast velocity by which value of product of mass into velocity of proton will be lower than the value of product of mass into velocity of the golf ball which will result in larger value of wavelength of the proton.

What is the standard heat of reaction for the following reaction?
8090 [49]

Answer:

The correct answer to the question is

The standard heat of reaction for the reaction is

a. 216.8 kJ released per mole

Explanation:

The heat of reaction is given by [Heat of formation of products] - [Heat of formation of reactants]

In the question we have, heat of formation of the products Zn+2 (aq) = -152.4 kJ/mole and the heat of formation of the reactants = 64.4 kJ/mole

Therefore, the heat of formation of the reaction = (-152-64.4) kJ/mole or

-216.8 kJ/mole released
