4. When a turbine spins, it generates electrical energy and that is where it gets its name from.

1 answer:

8 0

If it’s hydraulic turbine then it’s potential and kinetic energy and if it’s a thermal process then heat energy from the fuel burnt runs the turbine

The empirical formula for trichloroisocyanuric acid, the active ingredient in many household bleaches is OCNCI. The molar mass o

TEA [102]

Answer:

These two are equivalent and valid:

$C_3Cl_3N_3O_3$

$Cl_3(CN)_3O_3$

Explanation:

The molecular superscripts for each atom in the molecular formula are determined by the number of times that the mass of the empirical formula is contained in the molar mass.

1. Determine the mass of the empirical formula:

$OCNCl$ :

Atomic masses:

O: 15.999g/mol
C: 12.011g/mol
N: 14.007g/mol
Cl: 35.453g/mol

Total mass:

15.999g/mol + 12.011g/mol + 14.007g/mol + 35.453g/mol = 77.470g/mol

2. Divide the molar mass by the mass of the empirical formula:

232.41g/mol / 77.470g/mol = 3

3. Multiply each superscript of the empirical formula by the previous quotient: 3

$O_3C_3N__3Cl_3$

Or:

$C_3Cl_3N_3O_3$

You might also write CN as a group:

$Cl_3(CN)_3O_3$

The complete balanced equation for the reaction between barium hydroxide and acetic acid is

TiliK225 [7]

Answer:

2 CH3COOH + Ba(OH)2 --> Ba(C2H3O2)2 + 2H2O

To make it less clustered, you can use Ac for C2H3O2.

2 HAc + Ba(OH)2 --> Ba(Ac)2 + 2H2O

The acetic acid reacts with the base barium hydroxide to form the salt barium acetate and water.

Let's check Electronic configuration of N in ground state

$\\ \sf\longmapsto 1s^22s^22p^3$

In exited state

$\\ \sf\longmapsto 1s^22s^22px^12py^12pz^2$

3 p orbitals

In hydrogen case

$\\ \sf\longmapsto 1s^1$

1 s orbital

Hence Hybridization

$\\ \sf\longmapsto s-p-p-p$

$\\ \sf\longmapsto sp^3$

Structure is tetrahedral .

Spare way:-

Bond pairs==3=>Bonding electrons=6
Lone pair=1=>Anti bonding electrons=2

Hybridization

$\\ \sf\longmapsto \dfrac{1}{2}[\sigma+\sigma *]$

$\\ \sf\longmapsto \dfrac{1}{2}[6+2]$

$\\ \sf\longmapsto \dfrac{1}{2}[8]$

$\\ \sf\longmapsto 4$

sp3 Hybridization
Shape-Tetrahedral .
