Answer:
2Na=Ca(OH)000.1 AgBr=2KF 2KBr=LiNO
Since I don't have the diagram I'm going off my best estimate and the flow of the positive and negative charged protons and neutrons create a flow of energy when collided through a circuit or in this case the wire
Word equation - calcium + oxygen -> calcium oxide
Chemical equation - Ca + O2 -> CaO2
Hope this helps!
Answer:
This question lacks options; the options are:
A) They moved more freely
B) They moved closer together.
C) The average speed increased.
D) The average kinetic energy increased
The answer is B
Explanation:
The water in the beaker is described to be in a liquid state of matter. Its temperature decreases from 50°C to 10°C when placed in a freezer by Kiley. This means that heat is gradually being lost as the liquid water undergoes freezing into a solid state.
When water in a liquid state is freezed, it's molecules, which were moving more freely begin to move closer together because the speed at which the particles in the liquid state moved has been reduced.
Volume of CO₂ obtained : 13 L
<h3>Further explanation</h3>
Reaction
C₂H₅OH + 3 O₂ ⇒ 2 CO₂ + 3 H₂0 + 8842 Joules
moles of ethanol=0.28
From equation, mol ratio ethanol : CO₂ = 1 : 2, so mol CO₂ :
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
Then volume of CO₂ :
