Copper and gold is the answer I believe
False should be your answer
Answer:
a = 4
b = 3
Explanation:
<u>SOLUTION :-</u>
Balance it by using 'hit & trial' method , and you'll get the answer :-
2Fe₂O + 3C → <u>4</u>Fe + <u>3</u>CO₂
⇒ a = 4 ; b = 3
<u></u>
<u>VERIFICATION :-</u>
<em>In reactant side of equation :-</em>
- Number of atoms in Fe = 2×2 = 4
- Number of atoms in O = 2×3 = 6
- Number of atoms in C = 3×1 = 3
<em>In product side of equation :-</em>
- Number of atoms in Fe = 4×1 = 4
- Number of atoms in C = 3×1 = 3
- Number of atoms in O = 3×2 = 6
Number of atoms of each element is equal in both reactant & product side of equation. Hence , the equation is balanced.
H₃As is stronger acid than H₂Se.
The H-A bond strength typically determines the size of the "As" atom in an acid; the smaller the "As" atom, the stronger the H-A bond. In the Periodic Table, the atoms get bigger and the bonds get weaker as you advance down a row, strengthening the acids.
<h3>What is acid?</h3>
Any molecule or ion that may donate a proton—a Brnsted-Lowry acid—or establish a covalent bond with a pair of electrons—a Lewis acid—is regarded as an acid. The first class of acids are the Brnsted-Lowry acids, often known as proton donors.
The compound is referred to chemically as lysergic acid diethylamide, or LSD as it is more commonly known. Using it may lead you to have a distorted perception of reality and objects because it has a potent hallucinogenic effect. LSD has an effect known as tripping.
Aqueous solutions of acids with a pH lower than 8 are frequently referred to as "acids," even though the term "acid" technically only refers to the solute.

We are given initially with 1.2 x 1024 molecules of water, added further with <span>5.0 moles of water. we are asked to determine the total number of molecules of water after the addition. We just </span> convert the number of moles to number of molecules. 5 moles of water is equal to 3.011x 10^24 molecules. The total number is that we add the initial and the additional, equivalent to 4.211 x10^24 molecules.
