How does energy play a role in different rock types forming? I had this question another time in my test and it's asking the same thing again.
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.

How many moles are there in 17.6g NaOH?
Answer:
The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide.
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.44moles are there in 17.6g NaOH.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. The stoichiometry represents the number of moles.
Mathematically,
number of moles of NaOH =given mass of NaOH÷ molar mass of NaOH
Molar mass of 1 mole of NaOH= 40 g/mol
mass of NaOH= 17.6g
Substituting all the given values in the above equation, we get
number of moles of NaOH = 17.6g ÷ 40 g/mol
number of moles of NaOH =0.44moles
Therefore, 0.44moles are there in 17.6g NaOH.

What force is necessary to accelerate a 1,200 kg car at a rate of 35 m/s2?
How much acceleration would the car have if a 30,600 N force was applied to
the car?
Explanation:
Given that,
Mass of a car, m = 1200 kg
Acceleration of the car, a = 35 m/s²
The force acting on the car is given by :
F = ma
F = 1200 kg × 35 m/s²
= 42000 N
If the force is 30,600 N, then acecleration is given by :
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{30600}{1200}\\\\a=25.5\ m/s^2[/tex]
Hence, this is the required solution.

How much carbon dioxide will be formed if 12.5 grams of oxygen reacts with 7.2 grams of propane?
Answer:66 grams of Carbon Dioxide.
Explanation:
The common currency of chemistry is moles. So it is necessary to change the mass of propane to moles. Then write a balance equation so the moles of propane to moles of Carbon Dioxide. Finally moles of Carbon Dioxide must be changed to grams.
C 3 H 8 + 5 O 2 = =3 C O 2 + 4 H 2 O
This is the balance equation for the burning of propane in Oxygen.
From the equation it can be seen that 1 mole of propane makes 3 moles of Carbon Dioxide a ratio of 1:3
Convert 22 grams of propane to moles by dividing by the molar mass of propane.
3 x 12 = 36 grams
1 x 8 = + 8 grams
total = 44 grams/ mole.
22
44
= .5 moles of propane.
Using the ratio of 1:3 .5 = 3( .5) = 1.5 moles of Carbon Dioxide.
Now multiply 1.5 moles of Carbon Dioxide by the molar mass of Carbon Dioxide
1 x 12 = 12 grams
2 x 16 = +32 grams
total = 44 grams /mole.
1.5 moles x 44 grams/mole = 66 grams.

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).
