  • The difference between single displacement reaction and double displacement reaction are:

Explanation:

in the chemical reaction an atom in a molecule is replaced by another atom forming the end product .this type of chemical reaction involved only two reactants for example zinc + copper sulphate give us copper sulphate + copper.double displacement reaction is the reaction in which two compounds react together to form two other compounds by mutual exchange of other ions is called double displacement reaction.this type of reaction is involved two or more than two reactants.for example AG and O3 + NaCl give us agcl + nano3

The molar mass of h2o is 18.01 g/mom . The molar mass of o2 is 32.00 g/moo .what mass of h2o on grams must react to produce 50.0
Julli [10]
Oxygen can be obtained from water using electrolysis process as follows:
2 H2O .............> 2H2 + O2

It is given that: 
molar mass of water = 10.01 grams and molar mass of O2 = 32 grams

From the balanced chemical equation, we can conclude that:
2 moles of water produce 1 mole of oxygen
2 x 18.01 = 36.02 grams of water produce 32 grams of oxygen.

To calculate how many grams of water must react to produce 50 grams of oxygen, we can use cross multiplication as follows:
mass of required water = 56.28125 grams

What are the advantages of using digital signals over analog signals?
Studentka2010 [4]

in digital signals, codes are used while in analogue signals do not use signals.

<h3>What are signals?</h3>

Signals are defined as the instructions which are transferred to another source in other to deliver a message.

There are two types of signals which include the digital and analogue signals.

The digital signals uses codes which is a secret way of sending messages while analogue doesn't use codes.
