0.446 g of hydrogen gas fills a 5.0 L bag determine the density of hydrogen
Oduvanchick [21]

The density of hydrogen : ρ = 0.0892 g/L

<h3>Further explanation</h3>

Given

mass of Hydrogen : 0.446 g

Volume = 5 L

Required

The density

Solution

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

The unit of density can be expressed in g/cm³, kg/m³, or g/L

Density formula:  

\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}

Input the value :

ρ = m : V

ρ = 0.446 g : 5 L

ρ = 0.0892 g/L

Write a word equation for 2ZnS(s)+3O2(g) -&gt; 2ZnS(s) + 2SO3(g)
hjlf

2ZnS(s)+3O2(g) -> 2Zns(s) + 2SO3(g)

the above given equation is unbalanced as it contains 4 moles of sulphur in the output but in the input there are only two aoms of sulphur so to balance the equation we will write the equation as given under

balanced equation is

2ZnS(s)+3O2(g) -> 2Zn(s) + 2SO3(g)


In words:

When 2 moles of solid zinc sulfide reacts with 3 moles of oxygen gas gives 2 moles of solid zinc  and 2 moles of sulphur trioxide gas.

If you are operating a power driven vessel that is underway in conditions of restricted visibility, what should you do
swat32
If you are operating a power driven vessel that is underway in condition of restricted visibility, you are expected to do the following: sound prolonged blasts every two minutes. If the vessel is underway but is not moving, it is expected to sound two prolonged blast every two minutes. When one hears any of the signal above, one is expected to reduce speed to the minimum that is needed to keep on course.

The pOH of a solution is 6.0. Which statement is correct?
I am Lyosha [343]

Answer : Option D) The pH of the solution is 8.0.

Explanation : pOH of a solution is a measure of hydroxide ion (OH^{-}) concentration in a particular solution. It gives the measure of alkalinity of a solution. Normally, aqueous solutions at 25°C have pOH which is less than 7 are usually alkaline, when pOH is found to be greater than 7 then they are acidic and when pOH will be equal to 7 then it is neutral.

pH + pOH = 14, this relationship is used to find pH of any unknown solution with given pOH value,

Here, we known pOH is 6.0, so we get,

pH = 14 - 6 = 8.0;

Hence, the pH will be 8.0.
