Answer:increasing the concentration of reactants

Explanation:

Collision is the phenomenon in which the reactant molecules come to nearest closness,as a result the reactants are converted into products.

Now the number of effective collision is directly proportional to the number of reactants added..

1. How would the world be like if the element named Boron did not exist? 2. How would our lives be if the element Boron did not
Flauer [41]
1. The world without boron would be like a "turtle hiding inside it's shell" Almost everything that we need biologically would not be supplied. There would be plant disorder because of lack of boron that is needed for plants growth. And it would be widespread around the world and causes large of scarcity of food production resulting to chain of reaction to other factors that is part of our daily lives. We are not that high-tech as now and the transition of technology would not be as what we would be expecting in the years to come. We may obtain some of it naturally but it would not be enough later on as the population keeps on growing.

2. Life is still life because we still have other resources we need but it would be quite different as Boron plays a vital role since the earth's formation. As it has many uses in the beginning of civilization as we relies on borates for almost everything. Probably, widespread of plant disorder, poor production of food, rampant of sickness may happen, increasing of pestilence that some of the key ingredient of household products relies on it.

An atom of sodium-23 (Na-23) has a net charge of +1. Identify the number of protons, neutrons, and electrons in the atom.
Mashcka [7]

Answer:

Explanation: Sodium has an atomic number of 11, so it has 11 protons. The atomic mass is 23, so there are 23 − 11 = 12 neutrons. The charge is +1, so there is 1 more proton than electrons, so there are 10 electrons

Identify the solvent and the solute in vinegar a dilute aqueous solution of acetic acid
Amanda [17]
In this case, we can say, The solvent is the water.
A solute is an acetic acid.
The solvent is the dissolving medium in a solution while solute has dissolved particles in a solution.
Example, sugar water. Sugar dissolves in water, so sugar is the solute whereby water is the solvent.
We can say vinegar is acetic acid in water.

Maru [420]

Answer:

B

Explanation:

Neutralization reaction is where you add equal moles or quantity of acid and base so that they both neutralize each other or "cancel" each other making the pH to be neutral which is 7. Group B is likely wrong as their pH is 5 which means they added too much acid, if they had equal acid and base their pH would be 7 however since they added more acid, there was still some acid left after the initial neutralization and this acid decreased the pH to 5.

What is inorganic compounds?

A material without both carbon and hydrogen is said to be an inorganic compound. Many inorganic substances, like water (H2O) and the hydrochloric acid (HCl) secreted by your stomach, do contain hydrogen atoms. In contrast, carbon atoms are only present in a small number of inorganic molecules.

A class of chemicals known as inorganic substances are devoid of carbon. Ammonia, hydrogen sulfide, all metals, and the majority of elements are examples (such as calcium).
