Answer:
24 mol Cu
General Formulas and Concepts:
<u>Chemistry</u>
Explanation:
<u>Step 1: Define</u>
RxN: 2Cu (s) + O₂ (g) → 2CuO (s)
Given: 12 moles O₂
<u>Step 2: Stoichiometry</u>
<u />
= 24 mol Cu
<u>Step 3: Check</u>
<em>We are given 2 sig figs.</em>
Our final answer is in 2 sig figs, so no need to round.
Answer:
Ionic compounds: They have high melting points and boiling points. That is, ionic compounds are non-volatile.
Covalent compounds: They have usually low melting points and boiling points. That is, covalent compounds are usually volatile.
Work can be totally transformed into heat (for example, by friction), whereas heat can only be partially converted into work.
<h3>What is a model?</h3>
A model is a depiction of something that is frequently too difficult to directly observe or display. Although experimental testing validates a model, it is only accurate in explaining specific characteristics of a physical system.
Work is defined as the transfer of energy to or from a system by any means other than heat.
A transfer of energy to or from a system by any means other than heat is called “work”. Work can be completely converted into heat (by friction, for example), but heat can only be partially converted to work. The Second Law of Thermodynamics, states that the complete conversion of heat into work is impossible.
Heat transmission in materials can be described using the kinetic particle model. Heat energy always travels from a high-temperature zone to a low-temperature region.
Thus, heat can do work by constructing a model.
