Answer: scientific explanation
Explanation:
A really good scientific explanation should do two main things: It should explain all the observations and data we have. It should allow us to make testable predictions that we can check using future experiments.
There are 13 atoms in the product
<h3>Further explanation</h3>
Given
Reaction
H2SO4 + 2KOH --> K2SO4 + 2H2O
Required
The number of atoms
Solution
In a chemical equation, there are reactants on the left and products on the right
Reactants : H2SO4 + 2KOH
Products : K2SO4 + 2H2O
The number of atoms is determined by their reaction coefficient and the subscript of the atoms in the compound
K2SO4 (coefficient = 1) :
K = 2 atoms
S = 1 atom
O = 4 atoms
Total atoms = 7 atoms
2H2O(coefficient = 2) :
H = 2 x 2 = 4 atoms
O = 2 x 1 = 2 atoms
Total atoms = 6 atoms
Total = 13 atoms
The electron geometry of a water molecule is tetrahedral even though the molecular geometry is bent.
As water molecule hybridisation is sp³ that provides it a electron geometry tetrahedral but due to presence of 2 lone pairs and 2 bond pairs its molecular geometry is bent.
The hybridisation sp³ makes electron geometry of a water molecule tetrahedral but the presence of 2 lone pairs makes its molecular geometry bent
Answer:
Nervous system directs your body to swear to release heat.
Explanation:
Sweat maintains homeostasis when overheating.
Answer:
The answer to the question is
The wave speed is 53.57 cm/s
Explanation:
The speed of a wave is the distance covered by the wave per unit time.
Wave speed is given by
v = f×λ
where v = The velocity of the wave
f = The wave frequency
λ = The wavelength of the wave
the speed v of the wave can also be expressed interms of the period as
v = λ/T
The freuency of the given wave is f = 5/(0.112 s) = 44.64 Hz and the wavelength is λ = 1.20 cm
Therefore the speed of the wave = 44.64 Hz × 1.20 cm = 53.57 cm/s
