No the equation is not balanced.

No this equation is not balanced because although the value of S is one on both left and right side the value of oxygen is not.As, the value of oxygen is 3 on the right side the left side has 3 multiplied by 2 which is 6
Thus, this is not a balanced equation

(I m not sure if it is called value though)

A mechanism for the decomposition of ozone is (2 O3 â†’ 3 O2). O3 â‡Œ O2 + OO + O3 â†’ O2 + O2What is the molecularity for the f

Gnesinka [82]

Answer:

The correct answer is option c.

Explanation:

Molecularity is defined as number of atoms , ions or molecules that must collide with one another so as to result in a chemical reaction.It is simply the sum of molecules of different reactants as represented in balanced chemical equation.

Reaction taking place in one step are said to be elementary reaction.

Reaction taking place in more than one step are said to be complex reaction.

A mechanism for the decomposition of ozone is given as:

1) $O_3 \rightarrow O_2 + O$

Molecularity for the first elementary reaction is 1. This because single ozone molecule is present.

2) $O + O3\rightarrow O_2 + O_2$

Molecularity for the second elementary reaction is 2. This because single ozone molecule reacts with 1 oxygen atom.

The Ksp for BaCO3 is 5.1x10^-9. how many grams of BaCO3 will dissolve in 1000ml of water

Amanda [17]

Answer:

= 0.014 g of BaCO3

Explanation:

Let x = mol/L of BaCO3 that dissolve.

This will give;

x mol/L Ba2+ and x mol/L CO32-

But;

Ksp = 5.1x10^-9.

Therefore;

Ksp = 5.1 x 10^-9 = (x)(x)

Thus;

x = molar solubility

= √ (5.1 x 10^-9)

= 7.1 x 10^-5 M

Therefore;

Mass BaCO3 = 7.1 x 10^-5 M x 1 L x 197.34 g/mol

= 0.014 g

How many moles of oxygen in 3.5 Mols of CH2O

o-na [289]

M of CH2O= 12+2+16=30 g/mol
So 30g/mol = 3.5 mol
=> 16g/mol*3.5 divide by 30 = 1.86 mol
I think
