What are the parts of the atomic theory
Anvisha [2.4K]

Answer:

Explanation:

Dalton’s Atomic Theory  

All elements are composed of tiny indivisible particles called atoms.

All atoms of the same element are identical.

Atoms of different elements are different(they have different sizes, masses, chemical properties, etc.).

Atoms of different elements can combine with each other in simple whole number ratios to form compounds. (Law of Definite Proportions).

Chemical reactions occur when atoms are separated, joined, or rearranged. However, atoms of one element are NOT changed into atoms of another element by a chemical reaction. (Law of Conservation of Mass).

What ultimately determines what type of solution you have? Why can’t we just use this property? Explain in terms of the tyndall
nirvana33 [79]

Answer:

The solutions are classified according to their ability to scatter light rays.

We can't just use this property because some true solutions also contain undissolved solute.

Explanation:

Tyndall effect refers to the ability of a solution to scatter light rays. True solutions do not scatter light rays while false solutions scatter light rays.

Colloid particles are not large enough to be seen with naked eyes unlike suspensions. We should not confuse a colloid with a suspension because in a suspension, the dispersed solutes are seen with naked eye.

What mass of metallic silver can form from 1.147 g of copper metal according to equation b?
Arisa [49]

Answer:

        \large\boxed{\large\boxed{3.894g}}

Explanation:

From similar question, equation (b) is

Molecular Equation:

  • Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)

Net Ionic Equation:

  • Cu(s) + 2Ag⁺(aq) → Cu²⁺(aq) + 2Ag(s)

<u>1. Mole ratio:</u>

       \dfrac{2molAg(s)}{1molCu(s)}

<u>2. Convert 1.147 g of Cu(s) to moles:</u>

  • Atomic mass of Cu: 63.546g/mol

  • Number of moles = mass in grams / atomic mass

  • Number of moles = 1.147 g / 63.546 g/mol = 0.01805 mol Cu(s)

<u />

<u>3. Calculate the moles of Ag(s):</u>

    0.01805molCu(s)\times \dfrac{2molAg(s)}{1molCu(s)}=0.03610molAg(s)

<u />

<u>4. Convert 0.03610 mol Ag(s) to grams:</u>

  • Atomic mass of Ag(s) = 107.868g/mol

  • Mass = 0.03610mol × 107.868g/mol = 3.894g
