Answer:
I think it's light production, color change (new/different), gas production (bubbles/fizzing - not boiling), precipitate, and temperature change
Answer:
To ensure provide and reliable data
Explanation:
Calibration ensures precise repeatable performance while preventing pipetting errors. Just the way measurement standards are established to distinguish valid and invalid processes, pipette calibration standards are designed to ensure the best pipette accuracy.
Answer:
The bulk of nuclear waste is in the form of <u>solid ceramic pellets</u>.
Explanation:
Nuclear fuel loaded into commercial reactors is generally in the form of solid ceramic pellets that are stacked into metal tubes and bundled together in fuel assemblies. After the atoms in the pellet split to release their energy, the pellets in tubes emerge as nuclear waste.

Propene has three electron groups surrounding the core carbon atom, as seen in the Lewis dot structure of the compound.
<h3>What is Lewis dot structure?</h3>
A Lewis Structure is a greatly condensed illustration of a molecule's valence shell electrons. It is used to display how the electrons are positioned around particular molecules' atoms. When two atoms are bonded together, electrons are depicted as "dots" or as a line.
Lewis structures, often referred to as Lewis dot formulas, electron dot structures, or Lewis electron dot structures, are diagrams that depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.

Answer:
70.0°C
Explanation:
We are given;
- Amount of heat generated by propane as 104.6 kJ or 104600 Joules
- Mass of water is 500 g
- Initial temperature as 20.0 ° C
We are required to determine the final temperature of water;
Taking the initial temperature is x°C
We know that the specific heat of water is 4.18 J/g°C
Quantity of heat = Mass × specific heat × change in temperature
In this case;
Change in temp =(x-20)° C
Therefore;
104600 J = 500 g × 4.18 J/g°C × (x-20)
104600 J = 2090x -41800
146400 = 2090 x
x = 70.0479
=70.0 °C
Thus, the final temperature of water is 70.0°C
