N2 H4 (1) + O2

Chemistry
1 answer:
Kruka [31]3 years ago

Answer:

d. 46.5 g

Explanation:

First, you need to start with a properly balanced equation:

N₂H₄(l) + 3O₂(g) -> 2NO₂(g) + 2H₂O(l)

Then, find the moles of water produced:

2H = 2.01568 amu

O = 15.999 amu

________________

18.01468 amu

52.4 g ÷ 18.01468 amu = 2.9087 moles

The mole ratio in our balanced formula between N₂H₄ : H₂O is 1 : 2, so divide moles of H₂O by 2 to get moles of N₂H₄

2.9087 moles ÷ 2 = 1.45435 moles of N₂H₄

Then, calculate the atomic mass of N₂H₄:

2N = 28.0134 amu

4H = 4.03136 amu

________________

32.04476 amu

Finally, calculate the mass in grams of N₂H₄:

1.45435 moles • 32.04476 amu = 46.604 g

the compound nacI is an example of a /an.. (A)covalent bond (B)Ionic bond (C) Metallic bond (D) none of the above
Misha Larkins [42]

The answer should be B, ionic bond.


Ionic bond is the bonding between a metal and a non-metal. While covalent bond is the bond between non-metals, and metallic bond is the bond between metals.


Since Na, sodium, is a metal, and Cl, chlorine, is a non-metal, the bond formed between them is an ionic bond. Sodium gives up an electron to chlorine inside this bonding.

Answer:

NH3 —> base

We will see ammonia attach itself to silver and not the other way around, silver therefore accepts electrons. So, silver is a Lewis acid and ammonia is a Lewis base, so this reaction is complex as ammonia reacts with the silver cation .

Any group that contains an empty orbital in its valence shell can be considered a Lewis acid, but the bases do not differ in the Brønsted system from those in the Lewis system. Thus, acids are divided into types, including:

Simple Cations

Theoretically, they can be considered as acids and therefore we can also expect their acidic strength to increase for the following reasons:

1. By increasing the positive charge on the cation.

2. Increasing the charge of the nucleus from one atom to another in any period in the periodic table.

3. By decreasing the radius of the cation.

4. Decrease in the number of electron shells in the cation.

Therefore, the acidity of cations of any chain of transition elements increases with increasing atomic number when their positive charge is equal. There are some examples that show the reaction of cations as Lewis acids:

A) the reaction of the silver ion with ammonia

b) aluminum ion hydration

c) Adding alcohol to the lithium ion

D) formation of a ferric cyanide ion

If you currently have 1 kg of Uranium^238, in how many years will you have 1/2 kg of Lead^206? PLEASE HELP!!!!!!!
Bogdan [553]
From literature, we would find that the half life of Uranium-238 is equal to 4.5x10^9 years. This is the same number of years to obtain 1/2 kg of Lead-206. Hope this answers the question. Have a nice day.
