Yes, Fe(s)+CuSO4→FeSO4(aq)+Cu(s) is a redox reaction. The reducing agent is Fe(s), while the oxidizing agent is CuSO4.

<h3>Oxidation-reduction reaction (redox)</h3>

Oxidation-reduction reaction is the type of reaction in which electrons are transferred from one element to another. A compound or an element either gains are looses an electron in redox reactions.

Fe(s)+CuSO4→FeSO4(aq)+Cu(s)

From the equation above, Fe(s) is the reducing agent because it gives away 2 electrons and undergoes oxidation reaction.

From the equation above, CuSO4 is an oxidizing agent because it gives oxygen to Fe(s) and undergoes a reduction reaction.

Therefore, the reducing agent is Fe(s), while the oxidizing agent is CuSO4.

How many moles are in 8.8 x 1024 atoms of magnesium?
Veseljchak [2.6K]

Answer:

15 mol Mg

Explanation:

Step 1: Find conversions

Avagadro's Number: 6.022 × 10²³

Step 2: Use Dimensional Analysis

8.8(10)^{24} \hspace{3} atoms \hspace{3} Mg(\frac{1 \hspace{3} mol \hspace{3} Mg}{6.022(10)^{23} \hspace{3} atoms \hspace{3} Mg} ) = 14.6179 mol Mg

Step 3: Simplify

We have 2 sig figs.

14.6179 mol Mg ≈ 15 mol Mg

HELP PLEASE I DONT KNOW WHAT THIS MEANS IM CONFUSED
Zielflug [23.3K]

Explanation:

In an alpha emission, an alpha particle is ejected from a large nucleus. An alpha particle is simply a helium nucleus (atomic number is 2 and mass number is 4) so that means that the atomic number of the emitting nucleus decreases by 2 and its mass number decreases by 4.

Data has been collected to show that at a given wavelength in a 1 cm pathlength cell, Beer's Law for the absorbance of Co2 is li
White raven [17]

Answer : The concentration of a solution with an absorbance of 0.420 is, 0.162 M

Explanation :

Using Beer-Lambert's law :

A=\epsilon \times C\times l

As per question, at constant path-length there is a direct relation between absorbance and concentration.

\frac{A_1}{A_2}=\frac{C_1}{C_2}

where,

A = absorbance of solution

C = concentration of solution

l = path length

A_1 = initial absorbance = 0.350

A_2 = final absorbance = 0.420

C_1 = initial concentration = 0.135 M

C_2 = final concentration = ?

Now put all the given value in the above relation, we get:

\frac{0.350}{0.420}=\frac{0.135}{C_2}

C_2=0.162M

Thus, the concentration of a solution with an absorbance of 0.420 is, 0.162 M
