Answer:

A. Solar, wind, hydro, nuclear, tidal, and biomass are renewable resources

B. Oil, coal, and natural gasses are the fossil fuels that are nonrenewable resources

C. It is important to move from nonrenewable to renewable because nonrenewable resources will run out and they also create greenhouse gases that hurt the enviroment and cause global warming. Renewable resources are cleaner and either don't run out, or replenish fast enough to not run out

Which statement accurately describes the reactants of a reaction?
krek1111 [17]

Answer:

C. substances that are used up in a reaction

Explanation:

Substances are combined in a chemical reaction to give rise to other substances. The substances that come together are called REACTANTS while the substances that are produced are called PRODUCTS.

Reactants are used up in the reaction to give rise to new products at the end of the reaction. For example, in the reaction as follows:

6CO2 + 6H2O --> C6H12O6 + 6O2

CO2 (carbon dioxide) and water (H2O) are the REACTANTS of the reaction, which are used up to form glucose and oxygen (products)

The Pfund series of lines in the emission spectrum of hydrogen corresponds to transitions from higher excited states to the n =
lys-0071 [83]

Answer:

\large \boxed{\text{4650 nm}}

Explanation:

The second line in the Pfund series corresponds to a transition from n = 7 to n = 5.

To calculate the wavelength of the transition, we can use the Rydberg equation:

\dfrac{1}{\lambda} = R_{H}\left ( \dfrac{1 }{n_{1}^{2}} - \dfrac{1 }{n_{2}^{2}} \right )

where

R_{H} = 1.097 \times 10^{7} \text{ m}^{-1}

If n₁ = 5 and n₂ = 7

\begin{array}{rcl}\dfrac{1}{\lambda} & = & 1.097 \times 10^{7} \text{ m}^{-1}\left ( \dfrac{1 }{5^{2}} - \dfrac{1 }{7^{2}} \right )\\\\ & = & 1.097 \times 10^{7} \text{ m}^{-1}\left ( \dfrac{1 }{25} - \dfrac{1 }{49} \right )\\\\ & = & 1.097 \times 10^{7} \text{ m}^{-1}\left ( \dfrac{49 - 25 }{49 \times25}\right )\\\\& = & 1.097 \times 10^{7} \text{ m}^{-1}\left ( \dfrac{24 }{1225}\right )\\\\ & = & 2.149 \times 10^{7}\text{ m}^{-1}\\\end{array}\\

\begin{array}{rcl}\lambda & = & \dfrac{1}{2.149 \times 10^{7}\text{ m}^{-1}}\\\\ & = & 4.65 \times 10^{-6} \text{ m}\\ & = & \mathbf{4650} \textbf{ nm}\\\end{array}\\\text{The wavelength of the line is $\large \boxed{\textbf{4650 nm}}$, which is in the $\textbf{infrared region}$}.
