What happens at the atomic level when a metal is subjected to pressure, such as a blow from a hammer

Komok [63]3 years ago

Answer: The metal gets distorted when it is subjected to pressure, such as a blow from a hammer.

Explanation:

A blow from the hammer on the metal is actually applying a high pressure that causes a strain into the metal.

Due to this strain, the atoms of metals get compressed resulting in the formation of a large force which will distort the metal. Therefore, the atoms of metal will move sides apart from each other.

How many moles are in 83.1g of CaBr2​
9966 [12]

Answer:

0.416 mol CaBr₂

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis

Explanation:

<u>Step 1: Define</u>

83.1 g CaBr₂

<u>Step 2: Identify Conversions</u>

Molar Mass of Ca - 40.08 g/mol

Molar mass of Br - 79.90 g/mol

Molar Mass of CaBr₂ - 40.08 + 2(79.90) = 199.88 g/mol

<u>Step 3: Convert</u>

<u />83.1 \ g \ CaBr_2(\frac{1 \ mol \ CaBr_2}{199.88 \ g \ CaBr_2} ) = 0.415749 mol CaBr₂

<u>Step 4: Check</u>

<em>We are given 3 sig figs. Follow sig fig rules and round.</em>

0.415749 mol CaBr₂ ≈ 0.416 mol CaBr₂

Construct a model to show the movement of matter and energy from plants into other organisms. Show how mass and energy are conse
ad-work [718]

Plants obtain energy from the sun during photosynthesis and pass it along the food chain.

<h3>What is a model?</h3>

A model is a representation of reality. We use models to understand what the real situation of things is like.

Let us recall that plants are the producers in the ecosystem. Energy flow from plants to animals. Plants obtain energy via the reaction 6CO2 + 6H2O --->C6H12O6 + ATP. This energy is passed along the food chain as organisms feed on each other.

Which half-reaction correctly represents oxidation?
Leokris [45]

Answer: Mg\rightarrow Mg^{2+}+2e^- represents oxidation.

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Example: Mg\rightarrow Mg^{2+}+2e^-

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Example: Mg^{2+}+2e^-\rightarrow Mg

Mg\rightarrow Mg^{2+}+2e^- represents oxidation.
