Before conducting any kind of calculation with a chemical reaction, you first need to make sure the reaction is this.
What is balanced?
Covalent bonds usually form between two atoms of this type of element
What are non-metals?
What is the law of conservation of mass?
Increasing this property causes molecules to move faster, increasing both the number of collisions and how many collisions have enough energy for a reaction to occur.
What is temperature?
There are this many liters in a decaliter
What is 10?
This type of organization tool makes balancing chemical equations a breeze!
What is a T-chart?
Perform this math operation with the molar mass to convert from grams into moles
What is division?
This ratio, between two coefficients in a balanced chemical reaction, is critical to stoichiometry calculations
What is a mole ratio?
This many liters of water are needed to produce a solution of 0.2 M with 3.24 mol of solute.
What is 16.2 L?
The number of this subatomic particle is the same in every atom and ion of a given element.
What are protons?
Draw a Lewis structure for NF3. Include dots for any non-bonding electrons
In covalent bonds, the atoms do this with the electrons in order to reach a full octet around each atom.
What is share?
The common mistake that was made by the person who balanced this reaction
4 C + 2 O2 --> 4 CO
What is not using the smallest possible coefficients?
Of the five ways to speed up reactions, the only one that is to decrease something is to decrease the size of this.
What is the container?
While Physics is the study of energy, Chemistry is the study of this
What is matter?
In unstable isotopes, the ratio of these two subatomic particles is not balanced.
What are protons and neutrons?
These two elements are exceptions to the octet rule.
What are hydrogen and boron?
How many Joules of energy does it take to heat up 43 grams of water (specific heat capacity=4.18 J/g*C) by 14 C?
2516 J
This is the concentration of a solution if it is prepared by diluting 143 mL of a 5.3 M solution to a final volume of 409 mL
What is 1.85 M?
This element has the electron configuration 1s2 2s2 2p6 3s2 3p4
What is sulfur?
The presence of these around the central atom is what makes the difference in determining if a molecule is linear or bent.
What are non-bonding/lone pairs of electrons?
Ammonia (NH3) has this molecular geometry
What is trigonal pyramidal?
When hydrogen reacts with oxygen to produce water, 4.2 mol of oxygen is expected to produce this many mol of water
What is 8.4 mol?
This is the equilibrium constant for the synthesis of ammonia when [H2]=0.5 M, [N2]=0.8 M, and [NH3]=2.4 M
N2 + 3 H2 <--> 2 NH3
What is 57.6?
Atoms of this element have the smallest atomic radius
What is helium?
