Which scientist is credited with developing the first scientific atomic theory?

Answers

Answer:

John Dalton

Explanation:

John Dalton was the first scientist to give the atomic theory. According to Dalton:

  • All substance is made up of atoms and atoms are indivisible.  
  • All atoms of an element have the same mass.  
  • A compound is formed by the combination of different atoms from different elements.  
  • A chemical reaction is the rearrangement of atoms.  

Dalton was the first scientist to create an atomic theory but he wasn't given any credit. J.J Thompson was credited for his theory (apple pudding)

What is the relationship
between different forms of energy?​

Answers

Answer:

Energy exists in different forms, all of which can be classified as either potential energy or kinetic energy. Potential energy is energy stored in an object due to its position or arrangement. Kinetic energy is energy of an object due to its movement - its motion.

Explanation:

Answer:The law of the conservation of energy states that energy is neither created nor destroyed. Instead, it is simply transferred from one type of energy to another, or from one form of energy to another. The difference between mechanical energy and kinetic energy is that kinetic energy is a type of energy, while mechanical energy is a form of energy.

Rust on weathered rocks is caused by _____.saltation
oxidation
hydrolysis
abrasion

Answers

Rust on weathered rocks is caused by the process of oxidation. Oxidation is a process of chemical weathering that occurs when oxygen combines with minerals in rocks. rust occurs when oxygen combines with iron in rocks to form the reddish brown iron oxide.

Answer: The correct answer is oxidation.

Explanation:

Rust is a reddish-brown colored compound which is formed by the oxidation of Iron to form ferric oxide. The formula for this chemical compound is Fe-2O_3

Oxidation is defined as the reaction in which addition of oxygen takes place.

The reaction for the formation of rust is given by the equation, we get:

4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3(s)

By Stoichiometry,

4 moles of iron metal reacts with 3 moles of oxygen gas to form 2 moles of ferric oxide.

Hence, the correct answer is oxidation.
