here can be a number of chemical processes by which a compounds can be broken down into simpler substances. The most common and wide-spread of such processes is Catabolism. Along with anabolism, catabolism make up the metabolism process for living organisms. In catabolism, complex chemical molecules (such as proteins, polysaccharides, etc.) are broken down into simpler molecules (such as amino acids, monosaccharides, etc.). This is often accompanied by release of energy in the form of ATP (adenosine triphosphate) molecules and intermediate metabolites (which can be used by the organism in the anabolic processes). The energy thus generated is used for operation and maintenance of cells (and consequently, the body).

Other processes that break down chemical substances into simpler substances, include depolymerization, decomposition, etc.

Hope this helps.

Which of the following statements is true about what happens during a chemical reaction?

tiny-mole [99]

Answer: The correct option is A.

Explanation: In a chemical reaction, reactants react to form a number of products.

For the formation of products, the bonds of the individual reactants must be broken and the bonds of the products must be formed.

For example: Formation of water from hydrogen gas and oxygen gas. Reaction follows:

$2H_2(g)+O_2(g)\rightarrow 2H_2O(l)$

The Bonds of hydrogen and oxygen molecule are broken and new bonds between hydrogen and oxygen atoms are formed to give water molecule.

What is the wavelength in nm of a light whose first order bright band forms a

miskamm [114]

Answer:

714 nm

Explanation:

Using the equation: nλ=d<em>sin</em>θ

where

n= order of maximum

λ= wavelength

d= distance between lines on diffraction grating

θ= angle

n is 1 because the problem states the light forms 1st order bright band

λ is unknown

d= $\frac{1}{700,000}$ or 0.0000014 (meters)

sin(30)= 0.5

(1)λ=(0.0000014)(0.5)

=0.000000714m or 714 nm
