Answer:cohesion is the action or fact of forming a united whole.
Water is very cohesive in that it "sticks" to itself. Cohesion is what allows a water droplet to form, for example. When water molecules surround one another, they settle toward a low energy state. ... Adhesion and cohesion are water properties that affect living and non-living things on earth through water molecules.
Explanation:
An ionic bindis a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. The electrical and thermal conductivity of metals originate form the fact that their outer electrons are delocalized. I hope this helps
Answer:
The answer to your question is the third choice.
Explanation:
CaCO₃ ⇒ CaO + CO₂
Check if the reaction is balanced or unbalanced
Reactants Elements Products
1 Calcium 1
1 Carbon 1
3 Oxygen 3
As the number of atoms in the reactant is the same that the number of atoms in the products we conclude that the reaction is balanced.
So the correct answer is balanced because the total number of oxygen atoms is 3.
Answer:
4.44 g Ne
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
0.220 mol Ne
<u>Step 2: Identify Conversions</u>
Molar Mass of Ne - 20.18 g/mol
<u>Step 3: Convert</u>
<u />
= 4.4396 g Ne
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
4.4396 g Ne ≈ 4.44 g Ne
