Most continuous spectra are examples of what we also call thermal radiation spectra. Why do we call them "thermal" spectra?

Chemistry

Answer:

They are emitted from heated objects

Explanation:

When objects are heated, they emit light at all wavelengths thereby forming a continuous spectrum. Electromagnetic radiation of all wavelengths and colours are usually represented in such spectrum. A thermal spectrum is quite a simple spectrum since it depends on temperature.

Help! I need help on how to do these problems.
svetlana [45]

Answer:

a. 3; b. 5; c. 10; d. 12

Explanation:

pH is defined as the negative log of the hydronium concentration:

pH = -log[H₃O⁺] (hydronium concentration)

For problems a. and b., HCl and HNO₃ are strong acids. This means that all of the HCl and HNO₃ would ionize, producing hydronium (H₃O⁺) and the conjugate bases Cl⁻ and NO₃⁻ respectively. Further, since all of the strong acid ionizes, 1 x 10⁻³ M H₃O⁺ would be produced for a., and 1.0 x 10⁻⁵ M H₃O⁺ for b. Plugging in your calculator -log[1 x 10⁻³] and -log[1.0 x 10⁻⁵] would equal 3 and 5, respectively.

For problems c. and d. we are given a strong base rather than acid. In this case, we can calculate the pOH:

pOH = -log[OH⁻] (hydroxide concentration)

Strong bases similarly ionize to completion, producing [OH⁻] in the process; 1 x 10⁻⁴ M OH⁻ will be produced for c., and 1.0 x 10⁻² M OH⁻ produced for d. Taking the negative log of the hydroxide concentrations would yield a pOH of 4 for c. and a pOH of 2 for d.

Finally, to find the pH of c. and d., we can take the pOH and subtract it from 14, giving us 10 for c. and 12 for d.

(Subtracting from 14 is assuming we are at 25°C; 14, the sum of pH and pOH, changes at different temperatures.)

"One has more oxygen atoms than the other" best distinguishes carbon dioxide from carbon monoxide

<u>Explanation</u>:

In both carbon monoxide and carbon dioxide, there is the presence of carbon and oxygen. However,they vary depending on the number of oxygen atoms.In carbon monoxide, there is the presence of one only  carbon and oxygen atom. Thus carbon monoxide is chemically represented as CO. Only about 0.2%ppm of carbon monoxide present in air.  carbon monoxide is toxic and causes death in human when not consumed is correct proportion.

Whereas in carbon dioxide, only one carbon atom,and two oxygen atom and hence chemically represented as co2.
