Answer:
0.314 s⁻¹
Step-by-step explanation:
Use the <em>Arrhenius equation.</em>
Data:
k₁ = 0.0275 s⁻¹; k₂ = ?
Eₐ = 75.5 kJ·mol⁻¹
T₁ = 20 °C = 293.15 K; T₂ = 45°C = 318.15 K
<em>Calculation:
</em>
k₂ = 0.0275 × 11.41
k₂ = 0.314 s⁻¹
When you need heat to make reaction happen it is endothermic.
If heat was on the right side then type of reaction would be exothermic.
Answer:
Inorganic Phosphorus,phosphate
The atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.
Carbon is known as a tetravalent compound.
It has four electrons in its outermost shell. It forms a covalent bond with other compounds.
The number of neutrons. = 6
Number of electrons = 6
Number of protons = 6
So the atomic number of the compound is,
The atomic number of an element = Number of protons present in its nucleus
The number of protons given in the compound is 6.
So the atomic number of the compound is also 6.
Carbon has six atomic numbers.
Therefore, the atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.

To the eye – taken by itself – Alpha Centauri A appears as the fourth-brightest star seen from Earth, just slightly outshone by Arcturus. However, the combined light of Alpha Centauri A and B is slightly greater than Arcturus, so in that sense it appears as the third-brightest star visible in Earth's sky.
