An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons.
<h3>What is an Arrhenius acid?</h3>
An Arrhenius acid increases the number of
ions in the water.
According to the Arrhenius theory, a substance which has hydrogen atom and can easily give hydrogen ion or proton in its aqueous solution is called as Arrhenius acid.
For example, when hydrochloric acid is dissolved in water, it forms chloride ion (
) and hydronium ion (
).

Answer: The specific heat of the Al is
.
Explanation:
![Q_{absorbed}=Q_{released}](https://tex.z-dn.net/?f=Q_%7Babsorbed%7D%3DQ_%7Breleased%7D)
As we know that,
![Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})](https://tex.z-dn.net/?f=Q%3Dm%5Ctimes%20c%5Ctimes%20%5CDelta%20T%3Dm%5Ctimes%20c%5Ctimes%20%28T_%7Bfinal%7D-T_%7Binitial%7D%29)
where,
= mass of water = 87.4 g
= mass of Al metal = 6.7797 g
= final temperature = ![28.67^0C](https://tex.z-dn.net/?f=28.67%5E0C)
= temperature of water = ![25.37^oC](https://tex.z-dn.net/?f=25.37%5EoC)
= temperature of Al metal = ![205.24^oC](https://tex.z-dn.net/?f=205.24%5EoC)
= specific heat of water = ![4.184J/g^0C](https://tex.z-dn.net/?f=4.184J%2Fg%5E0C)
= specific heat of Al metal = ?
Now put all the given values in equation (1), we get
![m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]](https://tex.z-dn.net/?f=m_1%5Ctimes%20c_1%5Ctimes%20%28T_%7Bfinal%7D-T_1%29%3D-%5Bm_2%5Ctimes%20c_2%5Ctimes%20%28T_%7Bfinal%7D-T_2%29%5D)
![87.4\times 4.184\times (28.67-25.37)^0C=-[6.7797\times c_2\times (28.67-205.24)]](https://tex.z-dn.net/?f=87.4%5Ctimes%204.184%5Ctimes%20%2828.67-25.37%29%5E0C%3D-%5B6.7797%5Ctimes%20c_2%5Ctimes%20%2828.67-205.24%29%5D)
![c_2=1.008J/g^0C](https://tex.z-dn.net/?f=c_2%3D1.008J%2Fg%5E0C)
Therefore, the specific heat of the Al is
.
Answer:
Bohr thought that electrons orbited the nucleus in circular paths; whereas in the modern view atomic electron structure is more like 3D standing waves. Bohr built upon Rutherford's model of the atom. ... He believed that electrons moved around the nucleus in circular orbits with quantised potential and kinetic energies.
Explanation:
Neptium-236 has 143 neutrons and a half-life of 154,000 years. It can decay ny electron capture, beta emission and alpha emission. For beta emission, the decay product is Plotunium-236. Hope this answers the question. Have a nice day.
