Reaction or NO Reaction
Does the reaction happen if there is ONE ppt and ONE aq?
Yes
What type of reaction is 2H2 + O2 → H2O:
Combustion
What is the general equation of synthesis?
A + B = C
Balance this! Na + Cl2 → NaCl
2Na + Cl2 = 2NaCl
What is the charge of silver in all chemical equations?
1+
Is this a reaction or a no reaction?
K[s] + Cr2O3[aq]-----> 3K2O + 2Cr
What is the law of conservation of mass?
Where the mass of reactants and products are =
What is the general equation for decomposition?
FeO + C → Fe + CO2
2FeO + C → 2Fe + CO2
What is the charge of Zinc in all chemical equations
2+
Will the equation: Al + CuCl2 be a reaction or not? Explain.
Reaction because Aluminum is more reactive than Copper.
What are the five signs of a chemical change?
Color, temperature, odor changes, and formation of solid/gas
What is the general equation for single replacement?
AB + C = AC + B
FeCl3 + NaOH → Fe(OH)3 + NaCl
FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl
NH3 + CuO → Cu + N2 + H2O
2NH3 + 3CuO → 3Cu + N2 + 3H2O
Find the products and determine if it is a reaction or not: CuSO4 + CaBr2.Explain.
No Reaction because both are aq.
Find the mistake: Xe + F → XeF6(NOT BALANCING):
Xe + F2 → XeF6
What is the general equation for double replacement?
AB + CD = AC + CB
SiO2 + C → ????(balance it)
SiO2 + 3C → SiC + 2CO
Label what represents the coefficient, and subscript. 2H2 + O2 → H2O
2H2 + O2 → H2O
The first number is the coefficient
The numbers that look like that they've been put on the next line or in a small font are subscripts. (Couldn't get the image to load.)
Write the complete, balanced equation, and if it is a reaction or not given the reactants:
Iron and Copper(II) Sulfate
2Fe + 3CuSO4—-> Fe2(SO4)3 + 3Cu
Reaction
Iron (II) Chloride combines with Silver Nitrate to form Silver Chloride and Iron (II) Nitrate
FeCl2 + AgNO3—> AgCl + Fe(NO3)2
What is the general equation for combustion?
There is no equation. The elements included in this type of reaction are hydrogen, carbon, and oxygen.
Al + H2SO4 → Al2(SO4)3 + H2(Balance it)
2Al + 3H2SO4 → Al2(SO4)3 + 3H2
What is the word equation for the following equation? FeCl2 + AgNO3 → AgCl + Fe(NO3)2.
Iron(||) chloride combines with silver nitrate to produce silver chloride and Iron(||) Nitrate.
