Answer:
Substance at the beginning of a reaction- reactant
Substance at the end of a reaction- product
Number placed before a compound in a chemical equation- stoichiometric coefficient
Explanation:
In a reaction equation, the species written on the left hand side of the equation are called the reactants.
The reactants combine to form the species on the right hand side of the reaction equation called products.
The stoichiometric coefficient is a number written before the formula of a compound in the reaction equation.
Answer:
110L
Explanation:
Boyle's Law states that P1×V1=P2×V2
Volume is indirectly proportional to Pressure so P×V is constant
P1=55atm
V1=6L
P2=3atm
V2 is to be found
P1×V1=P2×V2
6×55=3×V2
330=3×V2
Answer: V2=110L
Condensation occurs through the release of energy
1. How is the modern periodic table organized? Increasing atomic number
2. What information about an atom's properties can you read from the periodic table? Metal or not metal. Does it want to gain or lose electrons
3. How are the relationships of elements in a group different from the relationships of elements in a period? a group will have similar properties A period will have different properties
4. Would you expect Strontium (Sr) to be more like potassium (K) or bromine (Br)?
potassium
5. Barium (Ba) is in Group 2. Recall that atoms in Group 1 lose one electron to form ions with a 1+ charge. What type of ion does barium form? Ba+2
