NH4NO3->N2O+2H2O How many grams of NH4NO3 are required to produce 33.0 games of N2O
Answer:
the moles of N2O are 33/(14.2 + 16) = 0,75 (mol)
NH4NO3 -----------> N2O + 2H2O
0.75 <--- 0.75
=> The moles of NH4NO3 are 0,75 mol
=> m = 0,75(14.2 + 4 + 16.3) = 60 (g)
Explanation:
Answer:
60 grams of NH4NO3

What is an isotope and how are they formed?
Answer:
Long story short, isotopes are simply atoms with more neutrons — they were either formed that way, enriched with neutrons sometime during their life, or are originated from nuclear processes that alter atomic nuclei. So, they form like all other atoms.

Why can't krypton and xenon separate during the separation of gases in the air?
Answer:
The remaining gas is a mixture of argon, neon, krypton, and xenon. Because these elements are chemically very unreactive, chemical means cannot be used to separate them.
Explanation:
Answer:
They're in Group 0 as they have full outer shells meaning they are chemically unreactive as they already have full outer shells meaning they don't want to lose or gain any electrons. Thus, they can't separate during the separation of gases in the air.

Consider the reaction X + Z ?
Assume the following:
1) The product is an ionic compound.
2) Element X has three valence electrons
3) Element Z needs two valence electrons to have completed s & p subshells (full octet)
What would make the most sense for the formula of the product?
Answer:
X2Z3
Explanation:
Based on the clues, X is a metal and Z is a non-metal.
X could be aluminum and Z would need to be an element from the oxygen family.
How does the entropy of a geyser system change as energy is added to the system ??
Answer:
Entropy increases as temperature increases. An increase in temperature means that the particles of the substance have greater kinetic energy. The faster moving particles have more disorder than particles that are moving more slowly at a lower temperature.
Explanation:
The entropy of the system increase as the temperature increase because at higher temperature there will be more randomness in the molecules.
What is entropy?Entropy can be described as a measure of spontaneous changes that take place in a system. In simpler words, entropy is the tendency of the universe towards disorder.
Entropy measures of randomness or disorder of a thermodynamic system and is represented by ‘S’. The value of entropy is dependent upon the amount of substance so it is an extensive property.
The change in the value of entropy depends on changes in quantities such as temperature, pressure, volume, and the number of moles of substance present in the system.
When the temperature of the system increases the kinetic energy of the molecules increases and they start to move faster. Therefore, the entropy of the geyser system increase as energy is added to the system.

two oxides, X and Y are added seperately to dilute sulfuric acid and dilute sodium hydroxide. X reacts with dilute sulfuric acid but Y does not react. Y reacts with aqueous sodium hydroxide but X does not react. which type of oxide are X and Y ?
Answer:
c
Explanation:
x basic and metallic while y is acidic
The study of chemicals is called chemistry.
The correct answer is B.
The compound which has oxygen in it is called oxide. According to the question, the element is react with the acid and base.
The X only reacts with the acidic compound but not basic compound hence the element X is basic in nature. while Y only reacts with the basic compound, not X, hence the Y element is acidic in nature.
Therefore, the correct answer is B.

What is an ideal gas equation?
The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.
Using the ideal gas equation
PV =nRT
Where P is the pressure
V is the volume
n is the number of moles
R is the ideal gas constant (R = 0.08206 L atm mol⁻¹ K⁻¹)
T is the temperature.
From the given information
V =?
n = 7.59
and at STP
P = 1 atm
T = 273 K
Putting the parameters into the formula, we get
PV =nRT
1 atm x V = 7.59 mol x 0.08206 L atm mol⁻¹ K⁻¹ x 273 K
V = 170.034 L
Hence, 170.034 L is the volume of a container containing 7.59 moles of krypton gas at STP.
