Answer:
D
Explanation:
We must study the reaction pictured in the question closely before we begin to attempt to answer the question.
Now, the reaction is a free radical reaction. This implies that only one electron is transferred. The transfer of one electron is shown using a half arrow rather than a full arrow. The both species are radicals (odd electron species) and contribute one electron each.
Hence we must show electron movements in both species using a half arrow.
Answer:
Explanation:
Which is more reactive hydrogen or oxygen?
Hydrogen is not particularly reactive. For example, just mixing hydrogen and oxygen gas will not cause a reaction at room temperature, but many metal elements oxidize at least on the surface in air. ... It is combustible because oxygen wants electrons and takes them from hydrogen to form water.
Answer:
A = 0.023 m
Explanation:
The relation between the frequency of a radiation and its wavelength is given by the following expression.
where,
c is the speed of light (it has a constant value of 3.00 x 108 m/s)
A is the wavelength of the radiation v is the frequency of the radiation
In this case, the frequency is 13 GHz = 13 x
10° Hz = 13 x 1o° s-
The wavelength associated with this frequency is:
A = c/v = (3.00 x 10° m/s)/(13 x 10° s-") = 0.023
Answer:
b. A mole of chlorine gas contains 2 (6.02 * 10^23 ) atoms.
c. A mole of carbon dioxide contains two moles of oxygen molecules (CO2)
e. A mole consists of the number of particles in exactly 12g of naturally occurring carbon.
Explanation:
A mole of oxygen gas (O2) contains 2 (6.02 * 10^23) atoms
A mole of Ammonia gas (NH3) has a mass of 17.031g/mol
A mole is defined as the unit used in measurement of the amount of substances in the International System of Units.
A mole was initially defined as the number of particles in exactly 12g of naturally occurring carbon.
Therefore, options b, c and e are correct
