Answer& explanation:
The mechanism of action of chloramphenicol can be explained as follows:
Chloramphenicol binds to the 50S subunit of the ribosome, inhibiting the protein synthesis of the bacteria, thus having bacteriostatic action (inhibiting the growth of bacteria, preventing their proliferation).
In addition, chloramphenicol can be bactericidal (destroys bacteria) when in high concentrations, or when used against highly sensitive microorganisms, such as <em>Haemophilus influenzae</em> and <em>Streptococcus pneumoniae</em>. The mechanism of action for these bacteria, however, is not yet elucidated.
Answer:
0.062 moles of hydrogen gas
Explanation:
We must first out down the reaction equation before we can attempt to solve the problem.
Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)
Next we obtain the number of moles in 1.5 g of magnesium metal from;
Molar mass of magnesium = 24.3 gmol-1
Number of moles of magnesium= mass/molar mass = 1.5g/24.3gmol-1 = 0.062 moles
From the reaction equation;
1 mole of magnesium metal yields 1 mole of hydrogen gas
0.062 moles of magnesium metal will yield 0.062 moles of hydrogen gas
Therefore, reaction of 1.5g of magnesium metal with excess hydrochloric acid will yield 0.062 moles of hydrogen gas.

girl.... I don't even know what to say
Riparian zones can reduce the impact of water pollution is true.
The statement is true.
<h3 /><h3>What are Riparian zones?</h3>
The areas along the banks of rivers and other sources of surface water are known as riparian zones.
The floodplain and riparian buffers bordering the floodplain are included.
Riparian zones benefit streams, groundwater, and downstream land areas in numerous ways, both environmentally and recreationally.
Thus, the given statement is true.
