Answer:

Releases a lot of energy. When hydrogen a highly reactive element reacts with oxygen, it does so using immense force, when the bonds break high amounts of emery is released.

What is the equilibrium constant for the following reaction at 25°C?
N76 [4]

Answer:

2.45×10^54

Explanation:

Mg(s) + Zn2+(aq) = Mg2+(aq) + Zn(s)

From the equation;

n= 2 moles of electrons

E°anode= -2.37 V

E°cathode= -0.76 V

From E°Cell= E°cathode - E°anode

E°Cell= -0.76-(-2.37) = 1.61 V

Recall that E°cell= 0.0592/n log K

1.61= 0.0592/2 log K

log K = 1.61/0.0296

K= Antilog (54.39)

K= 2.45×10^54

In the essay box, compose a scientific report which includes your observations, data, and conclusions. The following questions s
timama [110]

Answer:

1. It depends what type of method you are using. if it is Height x Width x Length then it will not work for an irregular shape because it has extra pieces that would not be included.

2. The second method would work for both regular and irregular shapes because you would have to know or find out the volume of the regular shape to get the volume for the irregular shape.

3. It also depends on what you are doing, if you are doing a regular shape then use the first method, if it's an irregular shape then use the second method, if you do the maths correctly both should give you an accurate answer for what you want to achieve.

4. No, because the sugar would dissolve.

5. No, on this case the displacement method would not work because of the weight difference

How many grams are there in a 14.5 moles lithium permanganate
frutty [35]

There are 1825.6 g in a 14.5 moles Lithium permanganate

<h3> Further explanation</h3>

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass :

\tt mol=\dfrac{mass}{MW}

moles of Lithium permanganate = 14.5

Lithium permanganate (LiMnO4) MW=125.9 g/mol, so mass :

\tt mass=mol\times MW\\\\mass=14.5\times 125.9~g/mol\\\\mass=1825.6~g
