Answer:

carbon monoxide is a pure substance because it cannot be separated by any physical method.

Explanation:

A pure substance is also known as chemical substance, it is a form of matter having constant chemical composition and characteristic properties.

Also a pure substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds.

A mixture of milk and water (tea) can be separated by filtration (physical method).

A mixture of of sugar and water can be separated by distillation (physical method).

Also a casserole, pomegranate juice are separated using physical methods.

However, carbon monoxide constant chemical composition and characteristic properties, and it cannot be separated by physical method.

Therefore, carbon monoxide is a pure substance.

How many moles are in 8.30x10^23 molecules of H2o
LUCKY_DIMON [66]
You multiply avogadro's number to what you were given.
8.30x10^23 * 6. 0221409x10^23
=1.357*10^25

That should be the right answer but I'm not sure. It has been awhile since I have done this.

The product of the nuclear reaction in which 31p is subjected to neutron capture followed by alpha emission is ________.
faltersainse [42]
The product of the nuclear reaction in which 31p is subjected to neutron capture followed by alpha emission is ²⁸Al.
Nuclear reaction: ³¹P + n° → ²⁸Al + α (alpha particle).<span>
Alpha decay is radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and transforms into an atom with an atomic number that is reduced by two and mass number that is reduced by four.</span>

Elena held a rock weighing 1 N in her hand. The rock has no velocity. <br> KE________?
nignag [31]

KE = 0

<h3>Further explanation  </h3>

Energy is the ability to do work  

Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:  

\large{\boxed{\bold{KE=\frac{1}{2}mv^2}}}

So for two objects that have the same speed, the greater the mass of the object, the greater the kinetic energy  

The stone in hand is in a motionless state (at rest) so that its velocity (v) = 0, so it has no kinetic energy

But this stone can have <em>potential energy that is gained due to its height</em>
