Explanation:
Rock cycle(Attachment-1)
The rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes is the best answer.
What are rock cycle?The rock cycle is defined as the process through which the three main rock types i.e. igneous, metamorphic and sedimentary rock transfer from one type to another type.
The plate tectonics is defined as a theory that earth's outer shell is divided into large slabs of solid rocks known as "plates" that glide over earth mantle, the rocky inner layer above earth's core.
Thus, the rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes is the best answer.

Fermium-253 has a half-life of 0.334 seconds. How long will it take, in seconds, for a 96 atom sample to decay to 3 atoms?
Answers
The half life time period of decaying 96 atom sample to 3 atoms of Fermium-253 if it has a half-life of 0.334 seconds is 1.67 s.
What is half life time period?Half life time period is defined as the time interval which is required to decay the substance into half of its concentration. It is denoted by t(1/2).
As, atom decay in first half life time = 48 atoms.
Atom decay in second half life time = 24 atoms.
Atom decay in third half life time = 12 atoms.
Atom decay in fourth half life time = 6 atoms.
Atom decay in fifth half life time = 3 atoms.
So, we can see that in 5 half life time 96 atoms decay into 3 atoms.
So, time interval require to decay 96 atoms into 3 atoms is 5 × 0.334 = 1.67 s.
Thus, we concluded that the half life time period of decaying 96 atom sample to 3 atoms of Fermium-253 if it has a half-life of 0.334 seconds is 1.67 s.

TRUE OR FALSE:The basic atom has a neutral charge.
Answers
true because I already foresighted a whole lot of things that I was not able to
Answer:
True
Explanation:
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.

Element Q is a theoretical nonmetal with atomic number 57. Consider the isotope: Q-110. How
many electrons are in an atom of Q-110 if the atom has a charge of -2?
Answers
Answer:
This isotope has 59 electrons giving it a charge of -2.
Explanation:
To find this we have to understand isotope relates to the mass of the nucleus. This isotope has 59 electrons to counter the protons and give it a negative charge.
In an atom, the atomic number is equal to number of electrons , hence element Q has 57 electrons on addition 2 electrons that is -2 charge the number of electrons is 59 electrons.
What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Answers
The density of the rectangular block is 1.07 g/mL.
From the question, we have the mass of the rectangular block as 121g
The dimensions of the block are given as follows;9.1cm by 5.4cm by 2.3cm
So we have the volume of the block as; 9.1cm × 5.4cm × 2.3cm = 113 cm^3
Let us recall that; 1 cm^3 = 1 mL, so 113 cm^3 = 113 mL
Having said that, we must also remember that;
Density = Mass/volume
Density = 121g/113 mL
Density = 1.07 g/mL

You have a gas sample of carbon dioxide at 298 K. If the pressure is 0.827 atm what is the pressure in mmhg
Answers
Answer:
628.520 mmHg
Explanation:
1 atm = 760 mmHg
[tex](760 \div 1) \times 0.827[/tex]
The pressure of 0.827 atm in mmHg is 628.52 mmHg
Pressure has various units of measurement such as atmosphere (atm), pascal, mmHg, Newton per square metre (N/m²) etc. These units can be converted from one to the other.
Considering the question given above, we can convert 0.827 atm to mmHg as illustrated below:
1 atm = 760 mmHg
Therefore,
0.827 atm = 0.827 × 760
0.827 atm = 628.52 mmHg
Thus, 0.827 atm is equivalent to 628.52 mmHg

¿Qué son las fuerzas intramoleculares?
Answers
Respuesta:
Las fuerzas intermoleculares que actúan entre las moléculas se clasifican en : Dipolos permanentes. Dipolos inducidos. Dipolos dispersos.
Explicación:
Dentro de una molécula, los átomos están unidos mediante fuerzas intramoleculares (enlaces iónicos, metálicos o covalentes, principalmente). Estas son las fuerzas que se deben vencer para que se produzca un cambio químico. Son estas fuerzas, por tanto, las que determinan las propiedades químicas de las sustancias.
Sin embargo existen otras fuerzas intermoleculares que actúan sobre distintas moléculas o iones y que hacen que éstos se atraigan o se repelan. Estas fuerzas son las que determinan las propiedades físicas de las sustancias como, por ejemplo, el estado de agregación, el punto de fusión y de ebullición, la solubilidad, la tensión superficial, la densidad, etc.
