<span><span />It is water’s Ionization Property. Water Ionization also known as self-ionization or auto ionization of water creates a positive and Negative ion which is essential for chemical reactions. It is a reaction of pure water in where a water molecule and H2O combined to make a hydroxide ion. It usually occurs due to the electric field fluctuation between 2 neighbouring molecules. It is a property of pure water that mixed or dissociates to from a new substance which is a hydrogen ion (positive ion) and hydroxide ions (negative ion)</span>

The reaction for the formation of phosgene from carbon monoxide and chlorineCO + Cl2 --&gt; COCl2 is first order in CO and secon
Ilya [14]

Answer:

r = k . [CO] .[Cl_{2}]

Explanation:

Let´s consider the following reaction:

CO + Cl₂ ⇒ COCl₂

The general rate law is:

r = k . [CO]^{m}. [Cl_{2}]^{n}

where,

r is the rate of the reaction

k is the rate constant

[CO] and [Cl₂] are the molar concentrations of each reactant

m and n are the reaction orders for each reactant

Since the reaction is first order in CO, m = 1. The overall order is the sum of all the individual orders. In this case, the overall order m + n = 2. Then,

m + n = 2

n = 2 - m = 2 - 1 = 1

The reaction is first order in Cl₂.

The rate law is:

r = k . [CO]. [Cl_{2}]

If the atomic number of an element is 8 and the mass number is 16, the number of neutrons in an atom of that element is what? (s
Serjik [45]

Answer:

8.

Explanation:

Atomic number tells us the number of protons in an element. Mass number is the total amount of mass in an atom, and it comes from the sum of the mass of protons and neutrons, which are both considered to have a mass of 1 amu.

If the total mass is 16amu and 8amu comes from the 8 protons, the remaining mass comes from neutrons.

16 - 8 = 8

Which solution has a molality of 0.25m nacl?
Radda [10]
A 0.25m solution of NaCl is defined as a solution consisting of 0.25mol NaCl dissolved in 1kg water:
Which choice fits this definition: None does. I suggest that you recheck the data you have submitted - you have a mixture of moles, mass, etc and it is easy to make a mistake.
d) looks promising if it was: 1.0 mol NaCl dissolved in 4kg water.
I have overlooked C) as possible 0.25mol NaCl in 1kg water as being a little too obvious.

Newton’s second law can be written using two formulas, what are they?
wariber [46]

Answer:

In equation form, Newton's second law of motion is a=Fnetm a = F net m . This is often written in the more familiar form: Fnet = ma. The weight w of an object is defined as the force of gravity acting on an object of mass m. ... Friction is a force that opposes the motion past each other of objects that are touching.
