Answer:
NOCl structure has geometry of trigonal planar and N has sp2 hybridisation. N is the central atom because it is less electronegative than O atom and Cl cannot be the central atom because it only forms a single bond. So, the central atom of NOCl is N and its hybridisation
Answer:
In the first part of Lesson 1, it was mentioned that sound is a mechanical wave that is created by a vibrating object. The vibrations of the object set particles in the surrounding medium in vibrational motion, thus transporting energy through the medium.
Answer:
Total gas pressure is 1.60 atm
Explanation:
To solve this question we can use the Ideal Gases Law. We need to determine how many moles of each gas will be finally present at the flask of 7 L.
Let's asume the gas, are at Asbsolute T°, 273K
P. V = n . R . T
3.5 atm . 2L = n . 0.082 . 273K
(3.5 atm . 2L) / (0.082 . 273K) = 0.313 moles
(2.8 atm . 1.5L) / (0.082 . 273K) = 0.188 moles
Total moles = 0.313 mol + 0.188 mol = 0.501 mol
Let's calcualte the hole pressure
P . 7L = 0.501 moles . 0.082 . 273K
P = (0.501 moles . 0.082 . 273K) / 7L → 1.60 atm
The energy released when a chemical compound reacts to produce new compounds is called Bonding Energy.
Answer:
After 1.95x10⁴ s, total pressure is 0.34 atm
Explanation:
t(s) 0 1000 3000 7000
PTotal (atm) 0.15 0.16 0.18 0.20
These are the data of the experiment, so let's make a linear regression
X | Y
0 | 0.15
1x10³ | 0.16
3x10³ | 0.18
7x10³ | 0.20
You can do this by the calculator, but let's do it manually.
Y = mx + b
m = (Y₂ - Y₁) / (X₂ - X₁)
m = 0.18 - 0.16 / 3x10³ - 1x10³
m = 0.02 / 2x10³ = 1x10⁻⁵
b = 0.15 (y-intercept, where x is 09
Y = 1x10⁻⁵ X + 0.15
Notice that in the statement, after 7000 s, pressure is 0.22 atm
1x10⁻⁵ . 1.95x10⁴ + 0.15 = 0.34atm
