Answer: The relationship is a difference in temperature of less than 2.5 °C between air temperature and dew point is noticed when there is fog.
Explanation:
Answer:
H2 is the limiting reactant.
Explanation:
From the diagram above:
H2 => White ball
O2 => Red ball
Before the reaction
H2 => White ball => 10
O2 => Red ball => 7
After the reaction
H2O => White and red ball => 10
O2 => 2
From the simple illustration above, we can see that all the H2 were used up in the reaction but there are left over of O2.
This simply means that H2 is the limiting reactant as all of it is used up in the reaction while O2 is the excess reactant as there are leftover.
Answer: 0.147 grams
Explanation:
To calculate the moles :
According to stoichiometry :
2 moles of 
require = 2 moles of ![NaOH/tex]Thus 0.049 moles of [tex]Al](https://tex.z-dn.net/?f=NaOH%2Ftex%5D%3C%2Fp%3E%3Cp%3EThus%200.049%20moles%20of%20%5Btex%5DAl)
will require=
of 
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 2 moles of give = 3 moles of 
Thus 0.049 moles of give =
of
Mass of 
Thus 0.147 g of will be produced from the given masses of both reactants.
Answer:
<h2>227.27 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question we have
We have the final answer as
<h3>227.27 mL</h3>
Hope this helps you
HClO, perchloric acid is a weak acid. Unlike strong acids like HCl or H2SO4 it not dissociate completely but partially such that an equilibrium exists between the dissociated ions and the undissociated acid. The equilibrium is as shown below:
HClO + H2O ↔ H3O⁺ + ClO⁻
Since HClO is a weak acid, the reverse reaction is favored over the forward reaction. Thus apart from water, HClO will be present in large amounts.
