Explanation:
First:
we can start off by turning the fractions into decimals
so 2/3=0.66
and 3/5=0.60
and we add the whole number
3.66
- 2.60
which leaves you with 1.06
all that's left is turning it into a fraction

How many particles are in 3.4 moles of HCl?
Answer:
The volume is 77 L.
Explanation:
where P is pressure, V is volume, n is moles, R is the gas constant, and T is temperature in Kelvins.
The current STP temperature is 0∘C or 273.15 K (used for gas laws), and the pressure is 105Pa, which most people write as 100 kPa (both pressures are equal).

what is the most important part of an Atom? Why?
Answer:
I would say proton and electron are the two most important subatomic particles in an atom
Explanation:
The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.

Geothermal power plants drill deep wells underneath
Earth's surface to pump water that is heated by magma. The steam from this hot water spins a turbine
that is hooked up to a generator that produces electricity. The cold water is then pumped back into
Earth to be reheated.
Do you think geothermal energy is a renewable resource? Why or why not? What are the benefits of
using this energy to power homes and businesses? Can you think of any consequences to communities
or the surrounding environment?
I
Answer:
Geothermal provides a reliable source of energy as compared to other renewable resources such as wind and solar power. This is because the resource is always available to be tapped into, unlike with wind or solar energy.
Explanation:
Because its source is the almost unlimited amount of heat generated by the Earth's core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source.
Answer:
A geothermal power plant gets energy from the heat deep below the surface of the earth. Shafts are drilled down, often as deep as several kilometres, one to pump water down to the hot rocks, and another nearby which will allow the heated water (or steam) to rise up. This steam is then used to spin electricity turbines to generate electricity.

How many moles of Mg3(PO4)2 are in 350.00 grams of Mg3(PO4)2?
Answer:
1.3 moles/ 1.33150727 moles
Explanation:
350g x 1 mol/262.86g = 1.3 moles
The molar mass of Mg3(PO4)2 is 262.855 g/mol
Atomic weight of the parts:
Mg 24.3050 x 3 = 72.92
P 30.973762 x2 = 61.95
O 15.9994 x8 = 127.995
There are 262.855 grams in one mole, so
350.00 g x (262.855g/1 mole) = 1.33 moles Mg3(PO4)2
Okay so don't take this the wrong way when I ask this cause its for science.

How do you determine the charges on the ions in an ionic compound?
Answer:
To find the ionic charge of an element you'll need to consult your Periodic Table. On the Periodic Table metals (found on the left of the table) will be positive. Non-metals (found on the right) will be negative.
Explanation:
Jessica places 100. g of water at 20.0℃ in an insulated cup. The specific heat capacity of water is 4.18 J/(g℃). What is the final temperature of the water if 5000. J of energy is added to the water in the insulated cup?
Answer:
31.96°C
Explanation:
Given that,
Mass of water, m = 100 g
Initial temperature, [tex]T_i=20^{\circ} C[/tex]
The specific heat capacity of water is 4.18 J/(g℃)
We need to find the final temperature of the water if 5000. J of energy is added to the water in the insulated cup.
The heat added to the water is given by :
[tex]Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\\dfrac{Q}{mc}+T_i=T_f\\\\T_f=\dfrac{5000}{100\times 4.18}+20\\\\T_f=31.96^{\circ} C[/tex]
So, the final temperature is 31.96°C.

good luck on ur test i wish i could help u more but im only in 7th grade :/ and i dont know that yet, so sorry again! :(
Explanation:
please help me with this
Ok buddy- so if you grab your periodic table there should be numbers on the side... (REFER TOO IMAGE ONE) So then we find them on the periodic table... (REFER TO IMAGE TWO) and if we look at the number the higher it gets the more radioactive it gets, and thats why it stops because the atomic gets so high that the level can't even be able to be mad because it will just explode and when it does that its dangerous because of how radioactive it is... so if we look the more "gas" concentrated elements are seen at the top (i.e. the helium) So the order would be He, C, O, Ne, Ca, I
Then just do that for the rest of them and the numbers on the side are the positive (+) or negative (-) amount of atoms that the atom is missing or ha to be stabilized or over stabilized, but you will learn that later on when you go into periodic equations.
Hopefully this helped, have a wonderful day! :)

Answer:
i do not know
Explanation:
If you wanted to predict which elements are explosive how would you organize the periodic table?
Explanation:
on a table then all will put them in a box and try every one or yoy could put ir out side and try it on the table
Lower explosive elements should be placed on the left side and high explosive elements on the right side of the periodic table.
If we wanted to predict which elements are explosive we will organize the periodic table starting from least explosive to high explosive just like the arrangement is done in the modern periodic table in which elements having lower atomic number are present at the left side of periodic table.
Whereas the elements having higher atomic number are placed on the right side of the periodic table so we can conclude that we have to place less explosive elements on the left and more explosive elements on the right side of the periodic table.
