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.

Define motion of particles in matter
Wittaler [7]

Answer:

Explanation:

The states that all of the particles that make up matter are constantly in motion. As a result, all particles in matter have kinetic energy. The kinetic theory of matter helps explain the different states of matter—solid, liquid, and gas. ... Particles do not always move at the same speed.

Consider the reaction.
N76 [4]

Answer: m = 50 g ZnSO4

Explanation: First is convert the moles of Zn to the moles of ZnSO4 by having their mole ratio which is 2:2 based from the balanced equation. Next is convert the moles of ZnSO4 to mass using its molar mass.

0.311 mole Zn x 2 moles ZnSO4 / 2 moles Zn

= 0.311 moles ZnSO4

0.311 moles ZnSO4 x 161 g ZnSO4 / 1 mole ZnSO4

= 50 ZnSO4

A newly discovered element, Z, has two naturally occurring isotopes. 90.3 percent of the sample is an isotope with a mass of 267
blsea [12.9K]
atomic mass=percentage of isotope a * mass of  isotope a + percentage of isotope b * mass of  isotope b+...+percentage of isotope n * mass of isotope n.

Data:
mass of isotope₁=267.8 u
percentage of isotope₁=90.3%

mass of isotope₂=270.9 u
percentage of isotope₂=9.7%

Therefore:

atomic mass=(0.903)(267.8 u)+(0.097)(270.9 u)=
=241.8234 u + 26.2773 u≈268.1 u

Answer: the mass atomic of this element would be 268.1 u

Cu + 2AgNO3 →
netineya [11]

Answer: 292.54g of Ag

Explanation:

Cu + 2AgNO3 →Cu(NO3)2 + 2 Ag

mass conc. Of Ag = n x molar Mass

Mass conc. Of Ag = 2 x 108 = 216g

From the equation,

63.5g of Cu produced 216g of Ag

Therefore, 86g of Cu will produce Xg of Ag. i.e

Xg of Ag = (86 x 216)/63.5 = 292.54g
