Answer: The limiting reactant is the reactant that gets consumed first in a chemical reaction and therefore limits how much product can be formed.

Explanation:

^

Answer:

The third choice

Explanation:

The law of conservation of mass tells us that the mass of the reactants and products in a chemical reaction will be equal to one another. Equations follow the law of conservation of mass when they are balanced, which means that they have the same number and type of atoms on each side.

When individual atoms are counted, the third choice has the same number and type of atoms on each side: 1 gallium, three cesium and three fluorine.

Answer:

It tells how quickly products will be made.

The reaction rate provides information about how quickly products will be made in a chemical reaction.

The reaction rate is a measure of how fast a chemical reaction proceeds over time. It provides information about the speed at which reactants are consumed and products are formed during a reaction. The reaction rate is typically expressed as the change in concentration of a reactant or product per unit of time.

The reaction rate is influenced by various factors such as the nature of the reactants, concentration of reactants, temperature, surface area, and the presence of catalysts. By measuring the reaction rate, scientists can gain insights into the kinetics of a reaction and understand the factors that affect its speed.

The reaction rate is particularly important because it allows us to predict and control the rate at which products are formed. It is useful in various applications, including industrial processes, pharmaceutical development, and environmental studies. By manipulating the reaction conditions, such as adjusting the concentration of reactants or introducing a catalyst, we can alter the reaction rate to achieve desired outcomes.

In summary, the reaction rate provides valuable information about the speed at which products are formed in a chemical reaction, allowing us to understand and control the kinetics of the process.

Explanation:

Answer:

True

Explanation:

A titration can be defined as the experiment where the volume of known con concentration is mixed into another solution whose concentration is not known.

Most of the titration are acid-base titration. When performing titration the indicator which is used is usually phenolphthalein. The end point of the titration is the point where the indicator changes its color.

In case of acid base reaction, the end point is achieved when the phenolpthalein turns faint pink in color from transparent.

Hence, the given statement is correct, the indicator changes its color close to the end point of titration.

Answer:

An aqueous solution is water that contains one or more dissolved substances. The dissolved substances in an aqueous solution may be solids, gases, or other liquids.

False. To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from 10.0 M stock solution, 4.0 mL of the stock solution and 16.0 mL of water would be needed.  

Recall the law of diffusion that:

C1V1 = C2V2, where C1 = initial concentration, V1 = initial volume, C2 = final concentration, and V2 = final volume.

In this case, if C1 =10.0 M, V1 = ?, C2 = 2.00 M and V2 = 20.0 mL

V1 = 2 x 20/10

         = 4.0 mL

Hence, 4.0 mL of the stock solution would be taken. Since the final volume is 20.0 mL, only 16.0 mL of water would need to be added and not 20.0 mL.

Answer:An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999.

Explanation:

The mass of the atom with 8 protons, 8 electrons, and 8 neutrons would be approximately 16 atomic mass units as the number of electrons has an almost negligible contribution to the mass of the atom.

It is the sum of the mass of all the protons as well as the neutrons that are present inside the nucleus.

Atomic mass = total number of protons present in the nucleus + total number of neutrons present in the nucleus of an atom,

As given in the problem we have to find the atomic mass of the atom with  eight protons, eight electrons, and eight neutrons,

This given specified atom clearly represents the oxygen atom as it has eight electrons protons and neutrons each.

Thus, the atomic mass of the given atom would be 16.

Answer:Douse the fire with baking soda: The chemical compound sodium bicarbonate, commonly called baking soda, is effective for extinguishing this type of fire. It takes a lot of baking soda to smother a grease fire, so pour it on while the flames are still small for the greatest effect

Explanation:

The grease fire has been put down by the addition of sodium bicarbonate as the extinguisher.

Grease fire has been defined as the fire that has been started with the over heating of the cooking oil at home. The fire has been started with the burning of the flammable liquids.

The fire in the cooking oil has been controlled with the addition of the sheet over the fire and turning off the flame.

The addition of water to grease fire results in the splashing of water over the fire and the spreading, resulting in the hazardous effects.
