Answer:
<h2>
D. sunlight, climate, soil, water, and air</h2>
Explanation:
Did you know? An ecosystem is defined as any community of living and non-living things that work together. Ecosystems do not have clear boundaries, and it may be difficult to see where one ecosystem ends and another begins. In order to understand what makes each ecosystem unique, we need to look at the biotic and abiotic factors within them. Biotic factors are all of the living organisms within an ecosystem. These may be plants, animals, fungi, and any other living things. Abiotic factors are all of the non-living things in an ecosystem.

Answer:
Green design
Explanation:
The word ‘Green’ represents designs which are eco friendly and less harmful to humans and other organisms. It helps in the protection of natural resources such as water, air etc.
Green Design are also referred to as techniques and materials that reduce the negative environmental impact of a structure.
The answer is (3) its aqueous solution conducts an electric current. The definition of electrolyte is a substance that will ionize when dissolved in suitable ionizing solvents such as water.
For this problem, we use the Hess' Law.
ΔHrxn = ∑(ν*Hf of products) - ∑(ν*Hf of reactants)
The ν represents the corresponding stoichiometric coefficients of the substances, while Hf is the heat of formation. For pure elements, Hf = 0.
Hf of Al₂O₃ = <span>−1676.4 kJ/mol
</span>Hf of Fe₂O₃ = <span>-826.0 kJ/mol
Thus,
</span>ΔHrxn = 1*−1676.4 kJ/mol + 1*-826.0 kJ/mol
<em>ΔHrxn = -2502.4 kJ/mol</em>
Answer:
a. Beryllium,
b. Nitrogen
Explanation:
Most similar to strontium is beryllium, they both are in the 2d group.
Least similar to strontium is nitrogen. Strontium is a metal in the 2d group, Nitrogen is non-metal in the 15th group
