Answer:
0.33 ml
Explanation:
Formula for density: p = m/V (where p is <em>density</em>, m is <em>mass</em> and V is <em>volume</em>)
So, by applying the above formula:
Since it's C2, then it must be two Carbon atoms. Think of it this way; there are two atoms of Hydrogen in a water molecule, so we now have H2O.
Answer:
1 mole of CO2 and 2 mole H2O will be produced in the reaction.
Explanation:
N:B: I guess it will be 6 moles of O2 not CO2.
Balanced Equation: CH4 + 2O2 --> CO2 + 2H2O
Given,
1 mole CH4
6 moles of O2
According to Stoichiometry,
In the reaction,
2 mole O2 reacts with 1 mole CH4
1 mole O2 reacts with 1/2 mole CH4
∴6 mole O2 reacts with (1/2)*6 mole CH4
= 3 moles of CH4
But, there is only 1 mole CH4 provided. So CH4 is the limiting reagent.
Now,
According to Stoichiometry,
In the reaction,
1 mole CH4 produces 2 moles of H2O
Again,
According to Stoichiometry,
In the reaction,
1 mole CH4 produces 1 mole CO2
So, 1 mole of CO2 and 2 mole H2O will be produced in the reaction.
N:B:[Doing calculation with limiting reagent in problems like these gives you the most accurate answer].
<span>Chemical reaction is:
Zn+PbS<span>O4</span>→ZnS<span>O4</span>+P<span>b
</span></span>From the balanced equation 2 moles of Zn make 2 moles of ZnSO4
<span>You have 0.534 moles of zinc so you make 0.534 moles of ZnSO4. </span>
Molar mass of ZnSO4 = 161 g/mol
mass = no of moles * molar mass
mass = 0.534 * 161
mass = 85.974 g
Well, the colder something is, the less the molecules move around, making it harder for the substance to move
think of it as this:
extremely hot water=steam/gas, moves quickly
room tempurature=liquid, moves slower than steam/gas
frozen=solid, moves very slowly, if even
the colder it is, the slower water moves
