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?
Answers
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.
particles of liquids have enough energy to separate from other liquid particles true or false
Answers
Answer:
False
Explanation:
I particles have enough kinetic energy to partly overcome the force of attraction between them, matter exists as a liquid. The particles can slide past one another but not pull apart completely. This explains why liquids can change shape but have a fived volume.

How many moles of potassium are needed to react completely with 7.50 mol of chromium (III) oxide? Show work.
Answers
Answer:
45 mol
Explanation:
First you need to balance the equation:
6K + Cr2O3 = 3K2O + 2Cr
the proportion of the coeficients of potassium and chromium oxide is 6 to 1 so we need to multiply 7.5 by 6 to get 45.

Answers
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.

How does the entropy of a geyser system change as energy is added to the system ??
Answers
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.

Why does lithium have a higher ionization energy compared to sodium?
Answers
Answer:
There are 11 protons in a sodium atom but only 3 in a lithium atom, so the nuclear charge is much greater. ... The only factor left is the extra distance between the outer electron and the nucleus in sodium's case. That lowers the ionization energy.

Why can't krypton and xenon separate during the separation of gases in the air?
Answers
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.
