Answer:
a because a container is supposed to be disposed every once in a while
The question describes a type of container, likely a plastic bag or similar packaging material, which is disposable, flexible, allows for easy storage, but is also easily punctured.
The question seems to be asking about a type of
container
that is disposable, flexible, allows for easier storage, but is easily punctured. This could likely refer to something like a plastic bag or a flexible packaging material. These types of containers are often used in various industries due to their convenience and cost-effectiveness. For example, in the food industry, a plastic bag as a container is
disposable
after use,
flexible
to fit various shapes and sizes of products, allows for
easier storage
because they can be folded when not in use, but they are also
easily punctured
which can result in product damage if not handled with care.

B. Molecule
C. Matter
D. Compound
Molecule is a chemical substance that cannot be broken down into another chemical substance.
Answer:
The correct answer is A. An element.
Explanation:
An element is a chemical substance that cannot be broken down into another chemical substance.
Answer : Option D) the electrons in some metals pair up to create a magnetic field.
Explanation : Most of the metalsare magnetic in nature including some exceptions. When the unpaired electrons get aligned with the magnetic field they posses magnetism. Also there are some paired electrons in metals which align themselves according to the magnetic field and create magnetism in them.
The correct answer is C; Metals can become magnetic if they have many spinning electrons that create magnetic fields.
Further Explanation;
As long as there are many spinning electrons anything metal will become magnetic. Ferromagnetic is when there are only some certain types of metals that are attracted to magnetic. If you were to make an electromagnet, you would only need to take an insulated wire and wrap it around the metal that has ferromagnetic properties.

Answer: Since most of the dissolved CO2remains as CO2 molecules, Ka1(apparent) has a much larger denominator and a much smaller value than the true Ka1. The bicarbonate ion is an amphoteric species that can act as an acid or as a base, depending on pH of the solution. At high pH, it dissociates significantly into the carbonate ion (CO2−3):
Explanation: In organisms carbonic acid production is catalysed by the enzyme, carbonic anhydrase. CO2 is a potent electrophile having an electrophilic reactivity that is comparable to benzaldehyde or string α,β-unsaturated carbonyl compounds. However, unlike electrophiles of similar reactivity, the reactions of nucleophiles with CO2 are thermodynamically less favored and are often found to be highly reversible. Only very strong nucleophiles, like the carbanions provided by Grignard reagents and organolithium compounds react with CO2 to give carboxylates. In metal carbon dioxide complexes, CO2 serves as a ligand, which can facilitate the conversion of CO2 to other chemicals. The reduction of CO2 to CO is ordinarily a difficult and slow reaction:
