Add x on all of them I just took what ur taking rn !!!!!
Answer:
C₃H₄O₄
Explanation:
In order to get the empirical formula of a compound, we have to follow a series of steps.
Step 1: Divide the percent by mass of each element by its atomic mass.
C: 34.6/12.01 = 2.88
H: 3.9/1.01 = 3.86
O: 61.5/16.00 = 3.84
Step 2: Divide all the numbers by the smallest one, i.e., 2.88
C: 2.88/2.88 = 1
H: 3.86/2.88 ≈ 1.34
O: 3.84/2.88 ≈ 1.33
Step 3: Multiply all the numbers by a number that makes all of them integer
C: 1 × 3 = 3
H: 1.34 × 3 = 4
O: 1.33 × 3 = 4
The empirical formula is C₃H₄O₄.
Because area of the container has increased , there will be fewer of collisions per unit area and the pressure will decrease . Volume is inversely proportional to pressure , if the number of particles and temperature is constant
( V = 1/P) and number of particle is proportional to pressure if average Kinetic energy of the particle remain same , the average force particle will remain same too so at some places and there will be more collision and there is greater pressure
Answer:
1. Sp^3; Sp.
2. Isomers.
3. Weaker.
4. Atomic; hybrid.
5. Pi.
6. Electronegativity.
7. Resonance structures.
8. Sigma.
Explanation:
1. A tetrahedral carbon is Sp^3 hybridized while a linear carbon is Sp hybridized. A tetrahedral carbon typically comprises of four bonds that are 109. 5° apart while a linear carbon atom comprises of two (2) bonds that are 180° apart.
2. Two different compounds that have the same molecular formula are known as isomer. For example Butane and Isobutane, Methoxyethane and Propanol have the same molecular formula (numbers of hydrogen and carbon atoms) but different structural formula.
3. Pi (π) bonds are generally weaker than sigma (σ) bonds. This is because the orbital paths of Pi bonds are parallel thereby causing an overlap.
4. Hybridization is the combination of two or more atomic orbitals to form the same number of hybrid orbitals, each having the same shape and energy.
5. A Pi bond is formed by side-by-side overlap of two p orbitals.
6. The electronegativity is a measure of an atom’s attraction for electrons in a bond and indicates how much a particular atom "wants" electrons.
7. Two Lewis structures that have the same atomic placement and σ structure but a different arrangement of π electrons are called resonance structures.
8. All single bonds are Sigma bonds.
