<h3>Further explanation</h3>
The basic oxide is an oxide-forming a base solution.
These oxides are mainly from group 1 alkaline and group 2-alkaline earth
If this oxide is dissolved in water it will form an alkaline solution
LO + H₂O --> L(OH)₂ ---> alkaline earth
L₂O + H₂O --> LOH --> alkaline
So the basic oxides : Na₂O and MgO
Na₂O + H₂O --> NaOH (sodium hydroxide, strong base)
MgO + H₂O --> Mg(OH)₂ (magnesium hydroxide, strong base)
The aqueous solution of CO₂ , obtained by dissolving CO₂ in water
CO₂ + H₂O --> H₂CO₃ (carbonic acid)
In general, basic oxide is obtained from metal oxide, while acid oxide is obtained from non-metal oxide
Well a compound is 2 or more different molecules together. So if you see a periodic table you will see the elements to see if they are the same or not.
Everything on Earth can be easily described in terms of one of four forms of matter: solid, liquid, gas, and plasma. Students are familiar with the three common forms of matter: solids, liquids, and gases. A solid is an object that has a form.

Answer:
±0.005 g
Explanation:
The uncertainty depends on whether the measurement was obtained manually or digitally.
1. Manual
The minimum uncertainty is ±0.01 g.
It may be greater, depending on random or personal errors
2. Digital
Most measurements of mass are now made on digital scales.
A digital device must always round off the measurement it displays.
For example, if the display reads 20.00, the measurement must be between 20.005 and 19.995 (±0.005).
If the measured value were 20.006, the display would round up to 20.01.
If the measured value were 19.994, the display would round down to 19.99.
The uncertainty is ±0.005 g.
The scale shown below would display a mass of 20.00 g
Explanation:
Standardization is the process of creating protocols to guide the creation of a good or service based on the consensus of all the relevant parties in the industry. ... Standardization also helps in ensuring the safety, interoperability, and compatibility of goods produced.
