Well as far as I know to make one ton of sulfuric acid takes 1,000,000 grams, so the answer should be 98,000,000 grams

Determine the overall reaction and its standard cell potential (in V) at 25°C for the reaction involving the galvanic cell made

mel-nik [20]

Answer:

Standard cell potential is 0.56V

Explanation:

Standard reduction potential ( $E^{0}$ ) are given below-

$E_{Cu^{+}\mid Cu}^{0}=0.52V$

$E_{Fe^{3+}\mid Fe}^{0}=-0.04V$

As $E_{Cu^{+}\mid Cu}^{0}$ is greater than $E_{Fe^{3+}\mid Fe}^{0}$ therefore Fe will be oxidized to $Fe^{3+}$ and $Cu^{+}$ will be reduced to Cu

Oxidation: $Fe(s)-3e^{-}\rightarrow Fe^{3+}(aq.)$

Reduction: $Cu^{+}(aq.)+e^{-}\rightarrow Cu(s)$

------------------------------------------------------------------------------------------------------

Overall: $Fe(s)+3Cu^{+}(aq.)\rightarrow Fe^{3+}(aq.)+3Cu(s)$

Standard cell potential, $E_{cell}^{0}=E_{Cu^{+}\mid Cu}^{0}-E_{Fe^{3+}\mid Fe}^{0}=(0.52+0.04)V=0.56V$

Below is a list of terms used in characterizing solutions. Enter the correct term for each sentence. Note that not all of the te

AlladinOne [14]

Answer:

molality, mole fraction, solvent, solute, molarity.

Explanation:

The expression of concentration that provides the moles of solute per kilograms of solvent is molality.

$b=\frac{n_{solute}}{m_{solvent}(kg)}$

If you place 5 moles of sodium chloride and 4 moles of sucrose into 11 moles of water, the mole fraction of sodium chloride would be 0.25

$X(NaCl)=\frac{molesNaCl}{moles_{solution}} =\frac{5mol}{20mol} =0.25$

A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the solvent is water.

The solvent is the component in major proportion and the one that defines the state of the solution.

A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the solute is sodium chloride.

The solute is the component in minor proportion.

A way to express concentration that provides the moles of solute per liter of solution is molarity.

$M=\frac{n_{solute}}{V_{solution}(L)}$

select the equations that are correctly balanced. h2o 2o2? h2o2 fe2o3 3h2? 2fe 3h2o al 3br2? albr3 caco3? cao co2 can you clarif

natta225 [31]

The choices are as follows:
h2o + 2o2 = h2o2
fe2o3 + 3h2 = 2fe + 3h2o
al + 3br2 = albr3
caco3 = cao + co2

The correct answers would be the second and the last option. The equations that are correctly balanced are:

 fe2o3 + 3h2 = 2fe + 3h2o
caco3 = cao + co2

To balance, it should be that the number of atoms of each element in the reactant and the product side is equal.
