Activation energy is defined as the least amount of energy that is needed to be available in a chemical system with potential reactants in order to result a chemical reaction. Therefore, the correct answer would be the first option: the heat released in a reaction.
Answer:
230hz
Explanation:
Hello,
To solve this question, we gave to use the relationship between velocity-frequency-wavelength to find the frequency in this question.
V = Fλ
V = velocity or speed of the wave
F = frequency of the wave
λ = wavelength of the wave
Data;
V = 414m/s
λ = 1.8m
f = ?
V = fλ
f = v/λ
f = 414/1.8
f = 230hz
The frequency of the wave is 230hz
Answer:
32, 30 and 41
Explanation:
The problem here is to find the number of:
Protons, neutrons and electrons in Ge²⁺
In this ion,
We must understand that for a net positive charge to remain on an atom, the number of protons must be greater than the number of electrons.
Ge is Germanium with atomic number of 32;
So the number of protons is 32
Since the atom has lost two electrons;
Number of electrons now is 32 - 2 = 30
Number of neutrons is 41 from the periodic table.
I believe it will be A. Density, temperature, and viscosity, can be found in water through tests. Hope this helps! Mark as brainly please!
Answer:
Boiling point for the solution is 100.237°C
Explanation:
We must apply colligative property of boiling point elevation
T° boiling solution - T° boiling pure solvent = Kb . m
m = molalilty (a given data)
Kb = Ebulloscopic constant (a given data)
We know that water boils at 100°C so let's replace the information in the formula.
T° boiling solution - 100°C = 0.512 °C/m . 0.464 m
T° boiliing solution = 0.512 °C/m . 0.464 m + 100°C → 100.237 °C
