Answer:
B. Acid + base = salt + water
Explanation:
In accordance to the proposal of a scientist called Svante Arrhenius, an acid is a substance that increases the H+ concentration of a solution by dissociating into it while the base increases the OH- concentration of a solution by dissociating into it. Furthermore, Arrhenius stated that this two ions combine in an aqueous solution to give water.
Hence, Arrhenius acid-base reaction is the combination of an acid and base to produce salt and water as products. That is; Acid + base = salt + water.
Answer:
The Bohr model suggested that electrons orbited the nucleus in circular paths where as the modern model views the atom to consist of positively charged nucleus surrounded by electrons.
Explanation:
In the modern model, the nucleus contains two sub-atomic particles, the protons which are positively charged and the neutrons which are not charged.According to Bohr's model,the electron in a hydrogen atom travel around the nucleus in a circular orbit. In the modern model, electrons do not move around nucleus around circular obits.
