Answer:

protons and neutrons

Explanation:

An atom is said to be the simple units of matter and basic of describing elements structure. An atom of an element have protons , neutrons and electrons.

The protons and neutrons of an atom are usually located in the nucleus of an atom. The sum of the proton and neutron of an atom determines the atomic mass of an element. This means the proton and neutron plays a major role in determining the mass of an atom. The proton is usually positively charge and tends to repel each other in the nucleus of an atom. The neutron has no charge but usually possess more weight than the proton.

The electron is located at the outer parts of the atom. it usually revolve round the atom . The electron determines how the atoms of an elements bond with other atoms. For an electronic neutral charge of any atom the proton number is equal to the electron number.  

The picture above illustrate how the proton, neutron and electron reside in the atom.

What are the reasons global warming is caused my humans and animals. Plz help 100 points
pantera1 [17]
Global Warming has been increased by living organisms like animals and humans by many ways:

1) We burn fossil fuels, which is very bad for our Environment's health
2) Animals like cows & buffalo produces a lot of methane which causes Global Warming.
3) Animals cut a lot of trees for their products, so increase the amount of Carbon dioxide in the atmosphere, thus increases Global Warming.
4) We don't minimize our dependence on Non-renewable source of energy which 'causes a lot of pollution in the environment

Can a chemical reaction happen with only one substance? For example, if you select water as the first substance but you don't ad
KATRIN_1 [288]

Explanation:

Yes, a chemical reaction can happen with only one substance.

A typical example of such reaction is the radioactive decay.

Radioactive decay is the loss of elementary particles from an unstable nucleus, ultimately changing the unstable element into another more stable element. .

When radioactive elements are let alone, they decompose to form  stable harmless elements.

An example of radioactive decay is attached in the image below;

What is the freezing point (in degrees Celcius) of 4.14 kg of water if it contains 235.1 g of butanol, C 4 H 9 O H
Karolina [17]

Answer:

Explanation:

Molal freezing point depression constant of butanol Kf = 8.37⁰C /m

ΔTf = Kf x m , m is no of moles of solute per kg of solvent .

mol weight of butanol = 70 g

235.1 g of butanol = 235.1 / 70 = 3.3585 moles

3.3585 moles of butanol dissolved in 4.14 kg of water .

ΔTf = 8.37 x 3.3585 / 4.14

= 6.79⁰C

Depression in freezing point = 6.79

freezing point of solution = - 6.79⁰C .
