Answer:
Water and sanitation services contribute to greenhouse gas emissions. Choice of wastewater treatment technologies, improved pumping efficiency, use of renewable sources of energy, and within-system generation of energy offer potential for reducing emissions.
Explanation:
A for sure sparrows are like birds but sparrows build holes in trees and birds do nests in trees so for sure is a
Answer:
D) 2 NOCl(g) ⇄ 2 NO(g) + Cl₂(g); Kp = 1.7 × 10⁻²
Explanation:
In order to compare the degree of decomposition of these reactions, we have to compare the equilibrium constant Kp. Kp is equal to the partial pressure of the products raised to their stoichiometric coefficients divided by the partial pressure of the reactants raised to their stoichiometric coefficients. The higher the Kp, the more products and fewer reactants at equilibrium. Among these reactions, D is the one that has the highest Kp, therefore the one experiencing the largest degree of decomposition.
<u>Answer:</u>
For 1: The correct answer is Option D.
For 2: The correct answer is Option A.
<u>Explanation:</u>
Polar molecules are defined as the of molecules, in which two atoms that combine must be of different element and therefore can create a dipole. For a dipole, there must be a difference in electronegativity and that is achieved when two atoms of different electronegativity combine. The negative dipole or charge is created on the electronegative atom and positive dipole or charge is created on the electropositive atom.
Thus, the correct answer is option D.
Non-polar molecules are defined as the molecules which are formed when two atoms of same element combine, so that a dipole cannot be created. When there is no dipole, there will be no difference in electronegativity and this is achieved when two atoms of same electronegativities combine.
Thus, the correct answer is A.
Answer:
The answer to your question is below
13.- b
Explanation:
13. How many protons are present in total in a carbon atom?
(a) There are always twelve. No, atomic mass of Carbon is 12 but the number of protons is half the atomic mass (6).
(b) There are always six. The answer is correct. Carbon's atomic number is 6, that means that it has 6 protons.
(c) It depends on the isotope. It's wrong, depends on the isotope the number of neutrons but not the number of protons.
(d) There are always four. No, 4 is the number of protons of Beryllium.
14. Of the following, which molecule is most polar? (The electronegativities of the atoms are as follows: chlorine 3.0, boron 2.0, hydrogen 2.1, oxygen 3.5, carbon 2.5, and bromine 2.8.)
Oxygen, because of these elements is the one with the highest electronegativity.
