Answer: The percent yield is, 42%

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of carbon disulphide}=\frac{1.55g}{76g/mol}=0.020moles

\text{Moles of oxygen}=\frac{2.83g}{32g/mol}=0.088moles

The balanced chemical reaction is:

CS_2+3O_2(g)\rightarrow CO_2+2SO_2

According to stoichiometry :

1 moles of CS_2 require = 3 moles of O_2

Thus 0.020 moles of CS_2 will require=\frac{3}{1}\times 0.020=0.060moles  of O_2

Thus CS_2 is the limiting reagent as it limits the formation of product and O_2 is the excess reagent.

As 1 mole of CS_2 give = 2 moles of SO_2

Thus 0.020 moles of CS_2 give =\frac{2}{1}\times 0.020=0.040moles  of SO_2

Theoretical mass of SO_2=moles\times {\text {Molar mass}}=0.040moles\times 64g/mol=2.56g

Actual mass of SO_2 = 1.1 g

Now we have to calculate the percent yield

\%\text{ yield}=\frac{\text{Actual yield }}{\text{Theoretical yield}}\times 100=\frac{1.1g}{2.56g}\times 100=42\%

Therefore, the percent yield is, 42%

Stage of photosynthesis​
borishaifa [10]

Answer:

Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2.

Lorazepam is commonly given along with a neuroleptic agent. what is the purpose of administering the drugs together?
Nonamiya [84]

Neuroleptics are molecules that act on the nervous system by modulating both agitation and neuronal activity. These drugs have an effect countering the transmission of a neuromediator.

These side effects are numerous, among them there is tardive dyskinesia, including akathisia (a state of agitation, distress, and restlessness). This can be corrected by the administration of benzodiazepines such as lorazepam.
