Answer:
pH = 14
Explanation:
pOH = -log[OH-] = -log1,0 = 0
pH + pOH = 14
pH = 14 - pOH = 14 - 0 = 14
Answer: the statement that is wrong about uncouplers is option A ( they allow ATP synthesis with no electron transport).
Explanation:
An uncoupler is a molecule that disrupts oxidative phosphorylation by dissociating the reactions of ATP synthesis from the electron transport chain. They allow electron transport without ATP synthesis. Their mechanism of action is basically to transport protons back into the matrix, preventing the required buildup of charge on the other side.
2,4-DNP is an example of an uncoupler.
Answer:
156 g of AlCl₃ will be produced from 3.5 moles of HCl.
Explanation:
Given data:
Number of moles of HCl = 3.5 mol
Grams of AlCl₃ produced = ?
Solution:
Balanced Chemical equation:
3HCl + Al(OH)₃ → AlCl₃ + 3H₂O
Now we will compare the moles of AlCl₃ with HCl from balanced chemical equation.
HCl : AlCl₃
3 : 1
3.5 : 1/3×3.5 = 1.17 mol
Mass of AlCl₃ produced:
Mass = number of moles ×molar mass
Mass = 1.17 mol × 133.341 g/mol
Mass = 156 g
Thus 156 g of AlCl₃ will be produced from 3.5 moles of HCl.
All organic molecules must have carbon and hydrogen so it would be choice A
<span>Ground water depletion is one of the major problems. The best solution is to conserve water that we are having currently and to recycle those wasted water. water conservation can be done in many ways such as reduce the level of pumping the ground water, avoiding the use of chemicals, use of natural fertilizers, rain water saving, pumping water to the tanks from stored rain water in the ground, way of handling the water consuming jobs.</span>
