Answer:

2. they eat plants that get their energy from the sun

Explanation:

Based on the way energy flows through an ecosystem, animals could not survive if they did not have the source of plants. So, the sun's renewable energy is important to animals because the sun helps them grow their food.

I hope this helps and makes sense!

Which of the following is an example of a decomposition reaction? 1) H2 + O2 ----------→ H2O 2) MgO2 -------------→ Mg + O2 3) M
podryga [215]

Answer:

2) MgO ---→ Mg + O2

Explanation:

Chemical decomposition is defined as the breakdown or breaking of a single molecule or entity into two or more smaller fragments.

Chemical decomposition is usually regarded as the exact opposite of chemical synthesis. In most cases, the chemical reaction in which two or more products are formed from a single reactant is called a decomposition reaction.

Consider these ground-state ionization energies of oneelectron species:
SVETLANKA909090 [29]

Answer:

Explanation:

general expression for the ionization energy of any one-electron species.

=  z² x ground level energy / n²

z is atomic no , n is energy level .

ground level energy of

 H = 1.31 x 10³ kJ/mol

He⁺ = 2² x  1.31 x 10³ kJ/mol  =  5.24 x 10³ kJ/mol

Li²⁺ = 3² x  1.31 x 10³ kJ/mol   = 1.18 x 10⁴ kJ/mol

b ) the ionization energy of B⁴⁺.

= 5² x 1.31 x 10³ kJ/mol  = 32.75 x 10³ kJ/mol  

c )  minimum energy required to remove the electron from the n = 3 level of He⁺ per mole

= 5.24 x 10³ / 9  kJ/mol

= 5.82 x 10² kJ/mol

= 5.82 x 10² x 10³ / 6.02 x 10²³ J

.9667 X 10⁻¹⁸ J

= .9667 X 10⁻¹⁸ / 1.6 X 10⁻¹⁹ eV

= 6.042 eV

= 1237.5 / 6.042

= 204.82 nm
