Answer: A resource which we get naturally from the enviornment such as, air water, soil etc. is known as natural resources. Natural resources can be categories on the basis of renewability and it is of two types; renewable and non-renewable.
A natural capital is the stock of natural resources; which includes soil, air and all the living organisms present on this planet
Answer:a biological community of interacting organisms and their physical environment.
Explanation:
This question is incomplete, the complete complete question is;
Coulomb's law for the energy of interaction between two charged ions;
E = Ke × q1q2/r
Coulomb's constant Ke = 2.31 × 10⁻²⁸ J.m.
Calculate the bond energy in the ionic compound NaCl if the bond length is 2.36 × 10⁻¹⁰m
Answer:
the bond energy is -9.788 × 10⁻¹⁹ J
Explanation:
Given the data in the question;
Ke = 2.31 × 10⁻²⁸ J.m which is the same as; Ke = 2.31 × 10⁻²⁸ Nm L/c²
ionic compound NaCl;
q1 = charge on Na in NaCl = Na⁺ = + 1C
q2 = charge on Cl in NaCl = Cl⁻ = - 1C
given that bond length r is 2.36 × 10⁻¹⁰m
E = Ke × q1q2/r
we substitute
E = 2.31 × 10⁻²⁸ × (+1 × -1) / 2.36 × 10⁻¹⁰
E = -2.31 × 10⁻²⁸ / 2.36 × 10⁻¹⁰
E = -9.788 × 10⁻¹⁹ J { The negative sign means Attraction in ions }
Therefore, the bond energy is -9.788 × 10⁻¹⁹ J
Desert plants work hard to make use of what's available. They use the sun's energy to convert carbon dioxide (CO2) and water (H2O) into sugar, a process called photosynthesis. During this process, stomata on a plant's leaves and stems open to absorb carbon dioxide from the air and in return release oxygen. :)
It's this the whole question, or is there more information?
