An object's weight would affect the amount of friction it causes. (true)
Answer:
The explanation to your question is below.
Explanation:
In thermochemistry, reactions are classify in two groups.
- Endothermic reactions: are reactions that need energy (heat) from the surroundings to happen. If they are not heated, the products will not form.
Example:
2 H₂O + energy ⇒ 2H₂ + O₂
-Exothermic reactions: are reactions that release energy to the surroundings. They happen spontaneously.
Example:
CH₄ + 2O₂ ⇒ CO₂ + 2H₂O + energy (heat)
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
Answer:
0.013 moles Cl
Explanation:
Grams --> Moles Divide by Molar Mass
Molar Mass of Chlorine (Cl) is 35.5. This can be found on the Periodic Table.
Set Up: (0.456 g Cl) (1 Cl / 35.5 g)
0.456 g * 1 = 0.456
0.456 / 35.5 = 0.01284507
Round to 0.013
