Rutherford theorized that atoms have their charge concentrated in a very small nucleus.

This was famous Rutherford's Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles (helium atom particles, consist of two protons and two neutrons).  

Rutherford observed the deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.

That is different from Plum Pudding model, because it shows that most of the atom is empty space.

According to Rutherford model of the atom:

1) Atoms have their charge concentrated in a very small nucleus.

2) Major space in an atom is empty.

3) Atoms nucleus is surrounded by negatively charged particles called electrons.  

4) An atom is electrically neutral.

Answer:

The Following are the matching to this question:

1 \to c\\2 \to  b\\3 \to   a\\4   \to  e \\5 \to  d    \\6 \to  f

Explanation:

  1. It includes creating assumptions, extracting predictions through logical outcomes, and experimentation observation based on those projections.  
  2. Every information gathered only with sense is also an observation. It expresses concern relating to scientific research. It also helps research scientists gather data.  
  3. Its independent variable inside an analysis is a controlled variable. It's also called "manipulated," because it can change its parameter, which is controlled one.  
  4. The suggested explanation for an occurrence is a hypothesis. It belongs to the scientific method. That's an experimental forecast, which is checked.  
  5. The experiment manipulates the important variables, calculates the dependent variable, controls any alien variables.
  6. It "reacts" to improvements inside an experiment that they make. It is the result or consequence of an experiment.

Question 4 (2 points)<br> CuO(s) + H2(g)<br> Cu(s) +<br> H2O(1)<br> Balance the equation
CaHeK987 [17]

Answer:

CuO(s) + H₂(g) --> Cu(s) + H₂O(l)

Explanation:

It is already balanced. You can see that the values of the elements of the reactants are equal to the values of the elements of the products.

Answer:

Ca(OH)₂ + H₂SO₄     →     CaSO₄ + H₂O

Explanation:

Chemical equation:

Ca(OH)₂ + H₂SO₄     →     CaSO₄ + H₂O

Balanced chemical equation:

Ca(OH)₂ + H₂SO₄     →     CaSO₄ + 2H₂O

The given reaction is double displacement reaction in which anion and cation of both reactant exchanged with each other. Calcium hydroxide react with sulfuric acid and form calcium sulfate and water.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AD +CB
