Answer:

Oceanic lithosphere forms at midocean ridges, where hot magma upwells, and then cools to form plates as the material moves away from the spreading center. As the plate cools, heat flow decreases and the seafloor deepens

When a sample of rust was mixed with acid, the rust changed into two simpler substances: W and Z. The substances W and Z could n
julia-pushkina [17]

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.

3. Find the mass of 4.77 x 1022 atoms of scandium<br> (Sc).
iren2701 [21]

Answer:

Mass = 3.6 g

Explanation:

Given data:

Number of atoms of scandium = 4.77×10²² atoms

Mass of arsenic = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022× 10²³ is called Avogadro number.

one mole =  6.02×10²³ atoms

one mole × 4.77×10²² atoms / 6.02×10²³ atoms

0.08 mol

Mass of scandium

Mass = number of moles × molar mass

Mass = 0.08 mol ×  45 g/mol

Mass = 3.6 g

How can i prove that nascent oxygen more reactive than normal oxygen ?
laila [671]
Nascent oxygen has much higher reactivity than the oxygen bubbled through the reaction mixture. It doesn't stay nascent for long (you are right about it being converted quick to just O2), which is why it has to be generated in situ

What is the energy of light with a wavelength of 468 nm? (The speed of light
marshall27 [118]

The answer for the problem is explained below.

The option for the answer is "D".

<u><em>Therefore the energy of the light is  4.25 × 10^-19 J</em></u>

Explanation:

Given:

wavelength (λ) = 468 nm = 468×10^-9 m

speed of light (c) = 3.00 x 10^8m/s

Planck's constant is 6.626 x 10^-34J·s

To solve:

energy of light (E)

We know,

E =(h×c) ÷ λ

E = ( 6.626 x 10^-34 ×  3.00 x 10^8) ÷ 468×10^-9

E = 4.25 × 10^-19 J

<u><em>Therefore the energy of the light is  4.25 × 10^-19 J</em></u>
