Volgvan3 years ago
3 0

Answer:

Increase the particle size of a reactant

Explanation:

Let me rewrite this question. I am assuming that it should be as follows,

If you  _____ the particle size of a reactant then the reaction rate will increase because of the reactant's surface area is exposed allowing more particles to make contact with each other.

And, here we are being asked to fill this dash line _____

It could only be that the particle size increases or decreases. Increasing the size of the reactant will increase the chance of collisions if the container with which the reactants are kept are constant. This would increase the reaction rate - thus _____ = increases.

An atom with an atomic number of 10 and a mass number of 24 would have ________.
Anastaziya [24]

An atom with an atomic number of 10 and a mass number of 24 would have 14 neutrons.

<h3>What is atomic number and mass number?</h3>

The term atomic number, conventionally denoted by the symbol Z.

Atomic number indicates the number of protons present in the nucleus of an atom, which is also equal to the number of electrons in an uncharged atom.

The mass number of a given atom is defined by the number of protons and neutrons present in the nucleus. In simple,

Protons + Neutrons = Mass Number

If you burn 10 kilograms of wood in a fire (combustion) what is the weight of the products after the fire has finished burning t
sleet_krkn [62]

The answer is: the weight of products is is equal the weight of the wood plus the weight of oxygen that was used to burn that wood, so weigh of the product is greater than 10 kilograms.

Conservation of mass (mass is never lost or gained in chemical reactions), during chemical reaction no particles are created or destroyed, the atoms are rearranged from the reactants to the products.

In this example wood (mostly carbon) and oxygen are reactants and carbon dioxide (mostly) is product of reaction.

What results when equal but opposite charges are present in two regions of a polar molecule? A. dipole B. ionic bond C. Electron
Masteriza [31]

Answer: A. dipole

Explanation:

Dipole can be defined as the separation of the equal and opposite charges present in the molecule via ionic bonding. The water molecule comprising of two molecules of hydrogen being positively charged and one molecule of oxygen being negatively charged are connected via ionic bonding thus water molecule is an example of dipole molecule. There is unequal distribution of the electrical density throughout the molecule.

Given: h2o(aq) + h2o(l) h3o+(aq) + oh–(aq) δh°rxn &gt; 0 when the temperature of a sample of pure water is raised above 25°c,
sesenic [268]
When Δ H > 0 that means this is an endothermic reaction, and we can assume heat as one of the reactants. SO when the temperature increases so the reaction will move rightward to decrease the reactants and increase the products and as the products increase it will make the Kw increase also as
 Kw = [Products] /[reactants].

So our answer will be: the value of Kw will increase.
