Answer:
Each giant planet has a core of “ice” and “rock” of about 10 Earth masses. Jupiter, Saturn, and Neptune have major internal heat sources, obtaining as much (or more) energy from their interiors as by radiation from the Sun.
Explanation:
Answer:
There are three types of intermolecular forces: London dispersion forces (LDF), dipole- dipole interactions, and hydrogen bonding. Molecules can have any mix of these three kinds of intermolecular forces, but all substances at least have LDF.
Answer:
Explanation:
Since this problem is incomplete, let us give a simple explanation to solve it.
In any reaction, we always have reactants that are in short supply and those that are in excess.
A reactant in short supply in a reaction is called the limiting reagent. This reactant will usually determine the extent of the reaction. When it is used up, the reaction will stop and will not proceed further.
To solve for the limiting reagent, convert the given mass to number of moles. Always work with number of moles.
Then write the balanced reaction equation.
Compare the moles from the balanced equation to that obtained. The reacting specie that is lesser in proportion is the limiting reagent
To solve the second part;
Compare the number of moles of the limiting reactant to that of the product i.e H₂O;
Use this number of moles to find mass;
Mass of H₂O = number of moles x molar mass
the balanced equation for the formation of water is as follows
2H₂ + O₂ ---> 2H₂O
molar ratio of oxygen to water is 1:2
mass of water produced is - 46 g
therefore the number of moles of water produced - 46 g / 18 g/mol = 2.56 mol
1 mol of oxygen reacts to give 2 mol of water assuming oxygen is the limiting reactant
for 2 mol of water to be produced 1 mol of oxygen has to react
therefore for 2.56 mol of water to be produced - 1/2 x 2.56 mol = 1.28 mol of oxygen should react
mass of oxygen reacted is - 1.28 mol x 32 g/mol = 41.0 g
mass of oxygen that should react is 41 g
