Answer:
The correct answer is A Energy leaves the iron bar and enters the wood until the temperature are equal.
Explanation:
According to the law of conservation of energy or the first law thermodynamics energy neither be created nor destroyed, energy is transferred from one form to another form.
Here iron bar is placed in wood block energy is transferred from iron bar to wood until the temperatures are equal.
Answer:
120 mol Mg
General Formulas and Concepts:
<u>Chemistry - Stoichiometry</u>
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
120 moles H₂
<u>Step 2: Identify Conversions</u>
RxN: 3 mol H₂ = 3 mol Mg
<u>Step 3: Stoichiometry</u>
<u />
= 120 mol Mg
Answer:
B.
the process by which rocks are broken down into sediment
The ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.
<u>Explanation</u>:
- This task seeks to examine the knowledge of the kinetic phase and characteristics of matters.
- Here we see the chef described that the ingredient's molecules are moving in place – solid.
- On the advent of causing the ingredient to change phase by transferring energy into it – the ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.
He limiting reagent<span> (or </span>limiting reactant<span>) in a chemical reaction is the substance that is totally consumed when the chemical reaction is complete. We determine by doing as follows:
11 L Cs2 ( 1 mol / 22.4 L ) = 0.49 mol Cs2
18 L O2 ( 1 mol / 22.4 L ) = 0.80 mol O2
Therefore, the limiting reactant would be oxygen since it only needs about 0.27 mol of Cs2 to be consumed completely.
