Answer:
Option C = 4.25 g
Explanation:
Ounce and grams are unit of mass. Ounce is larger unit while gram is smaller unit. The one ounce is consist of 28.35 g or we can say that one ounce is equal to 28.35 g. In order to convert the given ounce value into grams the value is multiply with 28.35 g.
Given data:
Mass = 0.15 ounce
Mass in gram = ?
Solution:
One ounce is equal to 28.35 g, so
0.15 × 28.35 = 4.25 g

Answer:
B
Explanation:
A chemical bond is formed when there is a transfer or sharing of electrons. When there is a transfer, what we have is that the electrons completely leave the outermost shell of an atom, usually metal to the outermost shell of another atom, usually a nonmetal. This particularly alters the electronic configuration of these atoms. This is ionic or electrovalent bonding
Now, electron sharing is also another way of chemical bond formation. Electrons might be shared between two atoms in a case principally known as covalent bonding. The electrons here are controlled by the 2 nuclei
Answer:
He conducted an experiment using gold foil and alpha particles.
Explanation:
Ernest Rutherford in 1911 performed the gold foil experiment which provided a better outlook to the structure of the atom. In his experiment, he bombarded a thin gold foil with alpha particles. Most of the alpha particles passed through the gold foil and just a few was deflected back.
This observation led Rutherford to propose the nuclear model of the atom in which an atom has a small positively charged centre and electrons moving round it.
Answer:

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>

<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>

<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
