Answer:
Yes
Explanation:
Yes, there are many energy forces that directly affect the formation of rocks and other substances. The Sun itself provides both energies in the form of heat/radiation and magnetic energy. Heat can get so intense when combined with pressure from being so far underground that it causes rocks to melt and become magma, which combines with other minerals and forms new types of rocks when they cool in the future. Magnetic energy helps push and pull the waves and wind on Earth which ultimately break down rocks into sand over the years.
2. Stronger intermolecular forces =______ boiling point
Stronger intermolecular forces = higher boiling point
The stronger the intermolecular forces, the harder the molecules are to pull/break apart, which means a higher boiling point.

what form of matter has a definite shape and takes up space?
Answer:
If something is in a solid state of matter, it has a definite shape and volume. The volume of an object is the amount of space it occupies. A block of wood placed on a table retains its shape and volume, therefore, it is an example of a solid. If a liquid is poured on that same table, there are very different results

How well do you think scientists can predict where a volcano will erupt? How well do you think scientists can predict when a volcano will erupt? Explain.
Answer:
Volcanologists can predict eruptions if they have a thorough understanding of a volcano's eruptive history, if they can install the proper instrumentation on a volcano well in advance of an eruption, and if they can continuously monitor and adequately interpret data coming from that equipment.

What volume, in liters, does 128 grams of O2 occupy at STP?
89.6 L
22.4 L
67.2 L
44.8 L
Answer: 89.7 L
Explanation:
89.6 volume, in liters, does 128 grams of O2 occupy at STP. Therefore, option A is correct.
What do you mean by volume ?A volume is simply the amount of space taken up by any three-dimensional solid. A cube, a cuboid, a cone, a cylinder, or a sphere are examples of solids. Volumes differ depending on the shape.
Every three-dimensional object requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an object within the boundaries of three-dimensional space. It is also known as the object's capacity.
1 mole Oxygen has mass 32 grams
Mole of Oxygen in 128 g mass = 128 g / 32 g/mol
= 4.0 mol O2
At Standard temperature and pressure this has volume
= 4.0 mol × 22.4 L/mol
= 89.6 L
Thus, 89.6 volume, in liters, does 128 grams of O2 occupy at STP, option A is correct.

(c) Magnesium has atomic number 12.
Magnesium exists as magnesium-24, magnesium-25 and magnesium-26 atoms.
Explain, in terms of protons and neutrons, why these atoms are isotopes
of magnesium
(2)
PLEASE HELP URGENT
Answer: The magnesium 24, 25, and 26 atoms are isotopes because they all have the same number of protons but they have different mass numbers
Explanation: isotopes of an element have the same number of protons but different mass number. So for magnesium 24, the number of protons is 12 and the number of neutrons is 12.
For magnesium 25, the number of protons would still be 12 but the neutrons would be 13.
Magnesium 26, the number of protons would be 12 and neutrons number is 14

How many moles is 118 grams of Argon
Answer:
[tex]\boxed {\boxed {\sf About \ 2.96 \ moles \ of \ Argon}}[/tex]
Explanation:
To convert from grams to moles we must use the molar mass, which is found on the Periodic Table.
Argon: 39.9 g/molUse the molar mass as a ratio.
[tex]\frac{39.9 \ g \ Ar}{1 \ mol \ Ar}[/tex]
Multiply by the given number of grams: 118
[tex]118 \ g \ Ar *\frac{39.9 \ g \ Ar}{1 \ mol \ Ar}[/tex]
Flip the fraction so the grams of argon will cancel each other out.
[tex]118 \ g\ Ar * \frac{1 \ mol \ Ar}{39.9 \ g \ Ar}[/tex]
[tex]118 * \frac{ 1 \ mol \ Ar}{39.9 \ g \ Ar}[/tex]
[tex]\frac {118 \ mol \ Ar }{ 39.9 }[/tex]
[tex]2.95739348 \ mol \ Ar[/tex]
The original measurement of grams had 3 significant figures, so our answer must have 3 sig figs.
For the number we calculated, that is the hundredth place. The 7 in the thousandth place tells us to round the 5 to a 6.
[tex]2.96 \ mol \ Ar[/tex]
There are about 2.96 moles of Argon in 118 grams.

What is the chemical formula for nickel (III) oxide, I know the answer but can someone explain how you would get it?
Answer:
the answer is d.
1. Write the symbols for each element.
2. Find the charge for each element using the Periodic Table. Write it above each element. (because there is a (III) after nickel, the charge of nickel is +3. oxygen is in group 16, which means it has a -2 charge.)
3. See if the charges are balanced (if they are you're done!)
- when you criss cross (getting Ni2O3, the charges are canceled out, so the equation is balanced.

During spontaneous fission, a nucleus of 25498Cf can produce 11846Pd, four neutrons, and what other nuclide?
Answer: 52Te - Tellurium
Explanation: Radioactivity occurs when an unstable nucleus of an element decompose into a stable element by emitting particles or forms of eletromagnetic energy. There are types of radioactivity and Spontaneous Fission is one of them.
In Spontaneous Fission, the unstable, also called parent, nucleus splits into two smaller nuclei and emitts one or more neutrons.
The reaction spontaneous fission of Cf is represented below.
25498Cf ⇒ 11846Pd + 4n + X
The characteristics of each element of the equation are:
1) The element Cf has atomic mass 254 and atomic number 98.
2) Element Pd has atomic mass 118 and atomic number 46.
3) Neutron is represented as n, has no atomic number and atomic mass 1.
Given these properties, to determine the other nuclide, we have to find out the nuclide's atomic number, as each element in the periodic table has its own atomic number.
At the left side of the equation, atomic number is 98. At the right side, element X's atomic number is
98 - 46 + 0 = 52
In the periodic table, the element with atomic number 52 is Tellurium, whose symbol is Te.
The other nuclide for the spontaneous fission is Tellurium (Te).
