Answer: 
Explanation: According to law of conservation of mass, mass can neither be created nor be destroyed.
Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
This is an example of combustion reaction in which hydrocarbon reacts with oxygen to form carbon dioxide and water. This is an exothermic reaction in which a large amount of heat is liberated, thus water also exists as vapors.
Free energy is the answer i hope this helped
Answer:
As trees grow, they help stop climate change by removing carbon dioxide from the air, storing carbon in the trees and soil, and releasing oxygen into the atmosphere. Trees provide many benefits to us, every day.
Answer:
Explanation:
Applying the Heisenberg uncertainty principle,
Δx X mΔv = h/4π
where Δx = uncertainty in measurement of position
Δv = uncertainty in measurement of velocity
m = mass of object
h = planck's constant
Here:
Δv = 0.4 A° = 4.0 x 10^-11 m
mass, m = 9.11 x 10^-31 Kg
Plugging the values,
4.0 x 10^-11 x Δ v = (6.626 x 10^-34) / (4 x 3.14 x 9.11E-31)
4.0 x 10^-11 x Δ v = 5.791 x 10^-5
Δv = 1.448 x 10^6 m/s, the uncertainty in its velocity
Answer = 1.45 x 10^6 m/s
Hybridization of atomic orbitals produces orbital shapes and spatial orientations that correlate to those predicted in VSEPR theory.
<h3>What is VSEPR theory ?</h3>
The number of electron pairs surrounding an individual molecule's core atoms can be used to forecast a molecule's shape using the chemical model known as the valence shell electron pair repulsion hypothesis. The two principal creators of the theory, Ronald Gillespie and Ronald Nyholm, gave it the additional moniker Gillespie-Nyholm theory.
- Hybrid orbital theory explains how these forms are created, while VSEPR theory predicts the shapes of molecules. VSEPR theory's central tenet is that electron pairs—both those in bonds and those that are alone repel one another. "Groups" refers to the electron pairs, both in bonds and lone pairs.
