Answer;
-The charges of the positive and negative copper ions cancel each other out.
Explanation;
-A normal atom has a neutral charge with equal numbers of positive and negative particles.That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number.
-Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion. If it gains one or more electrons, it now carries a net negative charge, and is thus anionic.
Answer:Complex carbohydrates are formed from monosaccharides, nucleic acids are formed from mononucleotides, and proteins are formed from amino acids. There is great diversity in the manner by which monomers can combine to form polymers. For example, glucose monomers are the constituents of starch, glycogen, and cellulos

Explanation:
Electronic configuration of uranium is given below -
1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p⁶4f¹⁴5d¹⁰6s²6p⁶5f³6d¹7s2²
Effective nuclear charge (Z eff) = Atomic number (Z) - Shielding constant (S)
<u>
Value of Shielding constant (S) can be calculated by using slater's rule :
</u>
S = 1 (0.35) + 9 (0.85) + 81 (1.00)
S = 0.35 + 7.65 + 81.00
S = 89
So,
Zeff = Z - S
Zeff = 92 - 89
<u>
Zeff = 3
</u>
Hence, Effective nuclear charge (Zeff) of uranium = <u>3
</u>

Answer:
The false statement is: (C) The average kinetic energy of the molecules is not related to the absolute temperature
Explanation:
According to the Kinetic Theory of Gases, gases are composed of <u>small fast moving particles that are in constant random motion</u>. These gaseous particles are known as molecules.
It is assumed that the mass of all the gaseous molecules is the same and the <u><em>intermolecular interactions (attractive or repulsive) are negligible</em></u>.
Also, the <em><u>total volume of all the gaseous molecules is considered to be negligible as compared to the volume of the container.</u></em>
According to this theory, <em><u>average kinetic energy (K) of the gaseous particles is directly proportional to the absolute temperature (T) of the gas, </u></em>by the equation:
<em>Here, </em><em> is the Boltzmann constant</em>
<u>Therefore, the false statement about the kinetic molecular theory is (C)</u>
