The brackets are indicating a(n) __Hydrogen___ bond.
1. Hydrogen
Solids and liquids have volumes thatdo not change easily. A gas, on the other hand, has a vol- ume thatchanges to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. The amount of space between the molecules in a gas can change easily.
Au³⁺ metal ion is reduced in the Au/Cr cell and Co²⁺ metal ion is reduced in the Co/Zr cell
<h3>What is a voltaic cell?</h3>
A voltaic cell is a cell that generates electricity by a spontaneous redox reaction.
It is an electrochemical cell, also known as a galvanic cell and
Electrical energy is created by converting chemical energy.
Examples of voltaic cells include the dry cell, nickel-cadmium cell, lead storage cell, and fuel cells.
The half-cell reactions for each cell are given by
; E° = 1.50 V
; E° = –0.74 V
; E° = –0.28 V
E° = –0.76 V
Thus, Au³⁺ is reduced in the Au/Cr cell and Co²⁺ is reduced in the Co/Zr cell

Answer:
0.80 Moles of Hydrochloric Acid would be required to produce 0.40 Moles of hydrogen gas due to the equation ratios
Explanation:
How many moles of hydrochloric acid are required to produce .40 moles of hydrogen gas?
Hydrochloric acid = HCl
Hydrogen gas = H2
H = 1+
Cl = 1-
HCL = H2 + Cl2
2HCl = H2 + Cl2
2:1:1
0.80 = 0.40 + 0.40
Answer:
CH₃(CH₂)₁₀COONa
Explanation:
The compounds given are
NaCl
CH₃COOH
CH₃COONH₄
CH₃(CH₂)₁₀COONa
CH₃(CH₂)₁₀CH₃
CH₃(CH₂)₁₀COONa will form micelle . Micelle are formed by soap solution which helps in the removal of oily dirt from our clothes . They are spherical shaped tiny droplet of oil which contains the tail of long chain organic compound like salt of long chain fatty acids . The surface of the droplet is lined with the tip of the chain which consists of negative charge of the tail end . On the average , each micelle contains a specific amount of charge . Due to it , they make colloidal solution in the water and gets washed off my water . The oily dirt is thus removed .
CH₃(CH₂)₁₀COONa ⇄ CH₃(CH₂)₁₀COO⁻ + Na⁺
CH₃(CH₂)₁₀COO⁻ part which is long chain of fatty acid gets adsorbed by oily droplet formed by oily dirt and forming micelle .
