Answer/Explanation:

A theory has lots of scientific evidence to back it up. We know this to be true based on lots of different diseases and studies of their spread.

A hypothesis is more of a starting point - an educated guess based on limited evidence. It requires further testing before becoming a theory.

A law is something that can be generalized to lots of contexts, and is universal. Such as the law of thermodynamics.

Answer:

involves the splitting of an atom into two or more fragments

Explanation:

The characteristic of nuclear fission is that it involves the splitting of an atom into two or more fragments. Details about nuclear fission can be found below.

Nuclear fission in radioactivity is a process by which the nucleus of a large atom splits into two or more smaller atoms.

Nuclear fission is usually accompanied by the release of a radioactive particle.

This suggests that the characteristic of nuclear fission is that it involves the splitting of an atom into two or more fragments.

Answer:

Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth ’s density is 5.51 grams per cubic centimetre. Density can also be expressed as kilograms per cubic metre (in MKS or SI units). For example, the density of air is 1.2 kilograms per cubic metre.

Answer:

Explanation:

To find the speed given the kinetic energy and mass we use the formula

[tex]v = \sqrt{ \frac{2KE}{m} } \\ [/tex]

where

m is the mass

v is the speed

From the question

KE = 15 J

m = 2.3 kg

We have

[tex]v = \sqrt{ \frac{2 \times 15}{2.3} } = \sqrt{ \frac{30}{2.3} } \\ = 3.61157559...[/tex]

Answer: B

Explanation:

To solve this we must be knowing each and every concept related to CaCO[tex]_3[/tex]. Therefore,  the correct option is option B among all the given options.

Carbonate of calcium One of the best-known compounds is CaCO[tex]_3[/tex]. Calcium carbonate is indeed a non-toxic, odorless substance. CaCO[tex]_3[/tex] is a white mineral found naturally in chalks, limestones, and marbles. It is a common material found in rocks as calcite and aragonite.

CaCO[tex]_3[/tex] is most commonly found in limestone. It is a sedimentary rock composed primarily of calcite and is the primary component of eggshells, snail shells, seashells, and pearls. Calcium carbonate is also used in medicine as a source of calcium or as an antacid. Although excessive calcium carbonate ingestion is dangerous and causes poor digestion.

Therefore,  the correct option is option B.

Answer: the 1st answer is neutrons and i think the 2nd is nucleus

Explanation:

The mass of an atom is found by adding its protons and neutrons. The electric charge of an atom is found by adding the charges of its protons and electrons.

The atomic mass of an element is the total number of protons and the number of neutrons carried by one atom of that element. The atomic mass of an element is usually expressed in grams or a.m.u.

The atomic mass of an element = No. of protons + No. of neutrons

or

The atomic mass of an element = No. of electrons + No. of neutrons

The atomic number gives us information about how many protons are inside the nucleus of the atom. Elements are recognized by the number of protons in the nucleus. Neutrons are uncharged elementary or subatomic particles that are stable when bound in an atomic nucleus.

As the electrons and protons are charged particles in an atom, therefore, the sum of the charge carried by them is equal to the electrical charge of the atom.

For a neutral atom, the number of protons present in an atom is always equal to the number of electrons.

Answer:

2.38 mol of Al

Explanation:

To find the number of moles in a substance, you simply divide by the atomic mass. In this case, the conversion table would look as follows:

[tex]\frac{64.1 g}{1}[/tex] * [tex]\frac{1 mol}{26.98 g}[/tex]

The gram units cancel, and you are left with the answer of about 2.38 moles of Aluminum.
