2x = 350- x
3x = 350
x = 350/x
therefore,
x = 116.67cm.
so, (350 - x)cm³ = (350- 166.67)cm³ = 233.33cm³
Hence distance covered by gas A is 116.67cm that by B is 233.33cm
Answer: It is a basic solution with pH =8.51
Explanation:
We were given that hydroxide ion concentration [OH-] as 3.26 x 10-6 M
But We know thar
[OH-] [H+] = 1 × 10^-14
To get the Hydrogen ion [H+] concentration, we have that
[H+] = 1 × 10^-14 M/[OH-]
= 1 × 10^-14 M/3.26 x 10-6 M
= 3.067 x 10^-9 M
But, pH = - log [H+]
Therefore,
pH = - log (3.067 x 10^-9)
pH=8.51
when pH > 7, The solution is basic, therefore a solution with pH =8.51 is basic.
You cant use the same fertilizer for all soils bc differnt soils have different nutrients like lets say ur growing tomatoes with cabbage it wouldnt work bc they need different nutrients for them to grow. This is used with trees, veggies, plants and fruits. it is true somw can use the same fertilizer if they can be grown with it. if you give it the wrong nutrients it can die or not grow
mass Hydrogen=9.376 g
<h3>Further explanation
</h3>
Reaction
2H₂+O₂⇒2H₂O
mass H₂ = 10 g
mol H₂(MW=2 g/mol) :
10 : 2 = 5
mass O₂=5 g
mol O₂(MW=32 g/mol) :
5 : 32 = 0.156
O₂ limiting reactant
mol H₂: mol O₂ = 2: 1, so mol H₂ :
2 x 0.156 = 0.312
mol H₂ :
5 - 0.132 =4.688
mass of H₂ :
4.688 x 2 =9.376 g

<u>Answer:</u> The equilibrium constant expression for the given equation is written below.
<u>Explanation:</u>
Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of products to the partial pressures of reactants each raised to the power their stoichiometric ratios. It is expressed as 
For the general chemical equation:
The expression of 
follows:
For the given chemical equation:
The expression of for above equation follows:
Hence, the equilibrium constant expression for the given equation is written above.
