Answer:
2Na=Ca(OH)000.1 AgBr=2KF 2KBr=LiNO
Answer:
1.18 × 10²⁴ particles Mg
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
- Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
Explanation:
<u>Step 1: Define</u>
47.7 g Mg
<u>Step 2: Identify Conversions</u>
Avogadro's Number
Molar Mass of Mg - 24.31 g/mol
<u>Step 3: Convert</u>
<u />
= 1.18161 × 10²⁴ particles Mg
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
1.18161 × 10²⁴ particles Mg ≈ 1.18 × 10²⁴ particles Mg
Answer:
The correct answer is "They can be separated by physical processes"
Explanation:
The definition of Mixtures is <em>the blending of two or more dissimilar substances</em>.
Mixtures can be divided into those that are homogeneous or heterogeneous meaning that they can be distributed evenly or can't be distributed evenly.
<span>Since you did not show any
picture, I will be describing Dalton’s atomic theory. The scientist thought
that the atom was the smallest particle in the universe is John Dalton. He
established five theories relating atoms. One, elements are made of extremely
small particles called atoms. Two, atoms of different element have different
sizes, mass and physico – chemical properties. Three, atoms cannot be divided
further, destroyed or created. It also follows the law of conservation of
energy. Fourth, atoms can combine to form compounds. And lastly, in chemical
reaction, atoms can be combined, separated or rearranged. </span>
