Answer: A. Cytoplasm

Explanation: Cytoplasm is a jelly, like material that fills up the remaining space in the cell. It is also responsible in making the shape of the cell. Without it, other parts of the cells or the organelles cannot make its function because it serves as the hallway of the transportation of the nutrients needed by each cell.

1.Chlorobenzene, C6H5Cl, is used in the production of chemicals such as aspirin and dyes. One way that chlorobenzene is prepared
miv72 [106K]

Answer:

m_{C_6H_5Cl}=65.7gC_6H_5Cl

Explanation:

Hello!

In this case, according to the given balanced chemical reaction:

C_6H_6 (l) + Cl_2 (g) \rightarrow C_6H_5Cl (s) + HCl (g)

We can see there is 1:1 between benzene and chlorobenzene as the relavant product; thus, since the molar mass of benzene is 78.11 g/mol and that of chlorobenzene is 112.55 g/mol, the theoretical yield for this reaction turns out:

m_{C_6H_5Cl}=45.6gC_6H_6*\frac{1molC_6H_6}{78.11gC_6H_6 }*\frac{1molC_6H_5Cl}{1molC_6H_6}*\frac{112.55gC_6H_5Cl}{1molC_6H_5Cl}   \\\\m_{C_6H_5Cl}=65.7gC_6H_5Cl

Best regards!

The activation energy for the reaction NO2(g)+CO(g)⟶NO(g)+CO2(g) is Ea = 75 kJ/mol and the change in enthalpy for the reaction i
lapo4ka [179]

Answer:

= 100kJ

Explanation:

The reverse reaction's activation energy of a reaction is the activation energy of the forward reaction plus ΔH of the reaction:

Ea of forward reaction =75kJ

∆H = -175 kJ/mol

Ea of reverse reaction = 75 +(-175)

= 100kJ

Note that a reverse reaction is one which can proceed in both direction depending on the conditions.
