The electron group arrangement of CF₄ is penta-atomic. The molecular shape is tetrahedral, and the bond angle is 109.5°.
<h3>What is the electron group arrangement?</h3>
Electron group arrangement is the arrangement of the electron of a compound. This is the geometry of the structure of the compounds. The different types of arrangements are, trigonal planar, tetrahedral, trigonal bipyramidal, or octahedral.
The carbon tetrafluoride has a tetrahedral structure, with a bond angler of 109.5°.
Thus, the electron group arrangement of CF₄ is penta-atomic. The molecular shape is tetrahedral, and the bond angle is 109.5°.

Water vapor is moisture in the air or humidity, they results from the evaporation of water, it also traps heat, and condenses to make clouds. Water vapor is water in its gaseous state instead of liquid or solid . It is extremely important to the weather and climate.
6.667 moles
Molar mass H3PO4 is 98 g/mol
mass of H3PO4 = 98 x 6.667 = 653.4g
mass of Cu = 27 , moles of Cu = 27 / 63.5 = 0.425
moles of Cr produce this Cu = .425 x 2/3 = 0.283 moles
or 0.283 x 52 = 14.7g
Answer:
(a) False;
(b) False;
(c) False;
(d) True.
Explanation:
(a) When equilibrium is reached, the forward reaction rate becomes equal to the reverse reaction rate, that's why the molarity of each species remains constant, but reactions don't stop.
(b) According to the principle of Le Chatelier, an increase in molarity of either reactants or products would lead to a disturbance of equilibrium. This disturbance would lead to the shift of equilibrium towards the side which would minimize such a disturbance.
(c) Equilibrium constant is only temperature-dependent, it's independent of molarity, pressure, volume etc. of any species present in the reaction.
(d) The greater the initial molarity of reactants, the more products can be formed, e. g., since the ratio of products to reactants should be kept constant, the larger the amount of reactants, the greater the amount of products formed to keep a constant ratio.
