Apart from their habits , bacteria and archea differ in cell wall structure and membrane lipid composition . A ll bacteria have peptidoglycans in the cells wall where as the archea do not . both also are different in the RNA polymerases and thus in their protein synthesis .I hope that can help you !!:))

Suppose a current of is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for s

WARRIOR [948]

The given question is incomplete. The complete question is:

Suppose a current of 0.920 A is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 47.0 seconds. Calculate the mass of pure silver deposited on a metal object made into the cathode of the cell.

Answer: 0.0484 g

Explanation:

$Q=I\times t$

where Q= quantity of electricity in coloumbs

I = current in amperes = 0.920 A

t= time in seconds = 47.0 sec

$Q=0.920A\times 47.0s=43.24C$

$AgNO_3\rightarrow Ag^++NO_3^-$

$Ag^++e^-\rightarrow Ag$

96500 Coloumb of electricity electrolyzes 1 mole of Ag

43.24 C of electricity deposits = $\frac{1}{96500}\times 43.24=0.00045moles$ of Ag

$\text{ mass of Ag}={\text{no of moles}\times {\text{Molar mass}}=0.00045mol\times 108g=0.0484g$

Thus the mass of pure silver deposited on a metal object made into the cathode of the cell is 0.0484 g

What is the limiting reactant when 19.9 g CuO react with 2.02 g H2?

Harlamova29_29 [7]

Answer:

Explanation:

use the equation

moles = mass/mr

=19.9/79.5

=0.250moles of CuO

then do the same for

H = 2.02/1

=2.02

so CuO is the limiting reagent because there is less amount of it.

Hope this helps :)
