compare solutions form from a metal oxide with a solution form from a nonmetal oxide
metal oxides: dissolve in water therefore form alkaline metals solution. nonmetal oxide: from acid solutions when dissolved in water
which of the following represents both the chemical composition and relative amount of each substance in a chemical change?
balance chemical equation uses chemical formulas to show reactants / products for each substance
which molecules always have the formula x2 in a balanced equation
hydrogen nitrogen oxygen fluoride chloride bromine
in a chemical equation 2h2 + 02 = 2h2o. what is the value of the coefficient for O2
it would be one because there's no number written in front of o2
what type of reaction is likely to occur between two elements
which of the following metals displace hydrogen from an acid but not to cold water
aluminum due to the protective oxide
what is one statement true about combustion reaction
carbon monoxide is produced in an incomplete combustion reaction but not in a complete combustion reaction
which substance could be a participate in a double displacement
H2O because h+, nh4 plus an alkali metals ion are soluble
what type of reaction do you expect to happen in the electrolysis
electorlysis is a reaction where external power is produced
what type of reaction might be able to reverse a decompression reaction
the decompression reaction can be reversed through synthesis involving combining hydrogen and oxygen from water
what is a fact about an incomplete flame
an incomplete flame is yellow due to the less heat and releases co in the air along with stood with CO2 and HO2 and not enough O2 is presented
what's a fact about a complete flame
the blue flame is complete because it is produced to the maximum heat and occurs sufficient O2 when presented
what is produced during a neutralization reaction
acid plus base equals water
which family of Meadows tend to form soluble ionic compounds
alkaline metals because one reacted with nonmetals they form ionic compounds
how does decomposition reaction result in the formation of gas in double displacement
decomposition reactions fall double displacement for carbon acids in the aluminum hydroxide
which metal is reactive
sodium because it's highly reactive
which metal does not react with hydrochloric acid
copper it doesn't produce hydrogen gas with it
what is the least reactive metal that can still displays hydrogen from cold water
sodium because alkaline metals produce hydroxide and hydrogen gas
synthesis reaction definition
two or more reactions create a single product and metals react with nonmetals
decomposition reaction definition
one reaction breaks into two or more products typically requires heat of electricity
single displacement reaction definition
one element that is replacing another compound
name three types of the single displacement reactions
a metal takes place of another metal and ionic compound 2. a metal to displace h2 from the water or acid 3. abnormal displaces another nonmetal to form a complete
what are the six reaction types
synthesis decomposition single displacement double displacement neutralization combustion
definition of combustion reaction
combustion reaction refers to the rapid reaction with oxygen to produce one or more oxide heat and light are also created
what happens in a complete flame
it creates CO2 and H2O produce blue flame at the maximum heat and occurs sufficient O2 that is presented
what happens in incomplete flame
create poisonous gas and stood with CO2 and H2O only occurs when not enough O2 is presented and produces a yellow flame there for Less heat
double displacement definition
the positive items of two ionic compounds exchange places
name three types of double displacement reactions
1. reaction producing a solid 2. reaction producing a gas 3m reaction producing water
what happens when reaction producing a solid in a double displacement
precipitates can be predicted using a soluble table
what happens when reaction producing a gas in a double displacement
decomposition reaction can follow double displacement in carbon acid and aluminum hydroxide
what happens when reactions producing water in a double displacement
it's called neutralization occurs when an acid and a base are combined
