Is a liquid soluble?

Answer:

Speed and velocity

Explanation:

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

Answer: anything that is a liquid

Answer:

Potassium permanganate has a molar mass of 158.04 g/mol. This figure is obtained by adding the individual molar masses of four oxygen atoms, one manganese atom and one potassium atom

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.

Answer:

as a verb it means make a serious or urgent request, typically to the public.

"police are appealing for information about the incident"

as a noun it means a serious or urgent request, typically one made to the public.

"his mother made an appeal for the return of the ring"

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! :)

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:

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).

Answer:

A stalagmite is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter and amberat.

and a stalactite means mineral formation that hangs from the ceiling of caves, hot springs, or man-made structures such as bridges and mines. Any material that is soluble and that can be deposited as a colloid, or is in suspension, or is capable of being melted, may form a stalactite.

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.

Cell

Explanation:

Cell is the smallest and basic unit of life

Answer:

The result of the procedure with the nail ended up going through reduction while the copper strip went through oxidation. The copper strip is the anode and the nail is the cathode. The anode is the + and the cathode is the - . Both the copper strip and the anode are placed in a tank filled with electrolyte solution. The direction of the flow goes from the positive to the negative (anode to the cathode).

Explanation:

I was doing the assignment too, hope this helps :)

The result of the procedure with respect to the coin and nail should be explained below.

Here the nail should be ended up through the decrease while on the other hand, the copper strip should be went through oxidation.

Here the copper strip should be considered as anode and nail should be considered as the cathode. Here the  anode should be + while the cathode should be -.

Both should be placed in the tank that should be filled with the electrolyte solution.

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.

Explanation:

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
