From the periodic table:
mass of Br = 79.9 grams
mass of Ar = 39.9 grams
Therefore,
molar mass of Ar = 39.9 grams
molar mass of Br2 = 2(79.9) = 159.8 grams

Now,
time for Ar / time for Br2 = sqrt(molar mass of Ar / molar mass of Br2)
time for Ar = 48 * sqrt(39.9 / 158.9)
time for Ar = 24.0528 minutes

when the following redoc reaction is balances (assume acidic solution), how many moles of water appear and on what side
PolarNik [594]

8 moles of water on the right side.

An oxidation-reduction or redox reaction is a reaction that involves the transfer of electrons between chemical items (the atoms, ions, or molecules involved in the reaction).

Redox reactions: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction.

Step 1:

MnO4- ----> Mn2+

2Cl- ------> Cl2

Step 2:

MnO4- --> Mn2+ + 4H2O

2Cl- -----> Cl2

Step 3:

8H+ + MnO4- ------> Mn2+ + 4H2O

2Cl- ----->Cl2

Step 4:

8H+ + MnO4- +5e- ------>Mn2+ + 4H2O

2Cl- ----> Cl2+ 2e-

Step 5:

16 H+ +2 MnO4- +10Cl- ----->2 Mn2+ + 8H2O+5Cl2

This is the balanced equation in an acidic medium.

That is 8, right side.

What is the hybridization of the C atoms in C2Cl4 ?
Dovator [93]

Answer:

sp2

Explanation:

Orbital hybridization is defined as the changes in the orbitals of atoms when they pair with electrons of other atoms to form chemical bonds.

C atoms in C2Cl4 or tetrachloroethene have a total of three bond pairs, two with each chlorine atom and one with other carbon atom and zero lone pairs. Thus, C atoms in C2Cl4 is  sp2 hybridized.

Hence, the correct answer is "sp2".
