Answer:

See the answer below

Explanation:

<em>The slide could have broken due to the ramming of the objective (especially the high power objectives) into the slide on the stage of the microscope while trying to bring the object on the slide into focus.</em>

It is recommended to <u>start with the lowest objective while trying to focus a slide</u>. Thereafter, the next higher objective can be switched to and the image brought into focus once again. This can be repeated until the desired magnification of the image is reached.

However, <u>at higher objective powers, the coarse adjustment knob should be avoided </u>to avoid the objectives touching/breaking the slide. Instead, the fine adjustment knob should be used.

Hence, the breaking of the slide in the illustration could have been due to the use of the coarse adjustment knob at higher objective powers and the ramming of the objective into the slide.

Why do we have to balance chemical equations
Lunna [17]

Answer:

  • <em>Chemical equations are balanced </em><u>to comply with the law of conservation of mass.</u>

Explanation:

Law of conservation of mass states that matter cannot be either created or destroyed.

A skeleton chemical equation shows the reactants and products of a chemical reaction without taking into account the real proportion in which the reactants combine and the products are obtained.

An example of a skeleton reaction is the combustion of methane:

  •    CH₄ + O₂ → CO₂ + H₂O

Such as that equation is shown, there are four atoms of hydrogen in the reactants but only 2 atoms of hydrogen in the products. Also, there are 2 atoms of oxygen in the reactants but three atoms of oxygen in the products. This seems to show that some atoms of hydrogen have been destroyed and some atoms of oxygen have been created. This is impossible as it is against the law of conservation of matter.

Then, to show a real situation, the chemical equation of combustion must be balanced, adjusting the coefficients. This is the balanced chemical equation:

  •    CH₄ + 2O₂ → CO₂ + 2H₂O

Now you see that the number of atoms of each matter is conserved: the number of carbon atoms in each side is 1, the number of atoms of hydrogen in each side is 4, and the number of atoms of oxygen in each side is 4. Thus, by balancing the chemical equation, the law of conservation of mass is not violated.

r-ruslan [8.4K]

Answers and Explanations:

Physical properties are characteristics of substances that can be seen without a change in its chemical composition.

Here, physical properties are:

- density

- color

- luster

- taste

- abundance

- source

I'm not completely sure what you mean by "source", but I'm going to assume you mean the substance's origin found in nature.

FILL IN THE BLANK. HELPPPP!
Sedbober [7]

Answer :The corrected answer is given below;


Weak bases react with <u>water</u> to form the hydroxide ion and the conjugate <u>acid</u> of the base. Concentration in solution does not affect whether an acid or a base is <u>strong </u>or weak.

The strength of an acid or a base is determined by the <u>dissociation constant</u> of the substance in solution.

The acid dissociation constant, <u>Ka</u>, is a quantitative measure of acid strength. A strong acid has a much <u>higher</u> Ka than a weak acid. The Ka of an acid is determined from measured <u>titration</u> values.


Hydrochloric acid and sulfuric acid are <u>completely</u> ionized in solution and are <u>strong</u> acids. Ethanoic acid, which is only about 1 percent ionized, is a <u>weak</u> acid. Magnesium hydroxide and calcium hydroxide are strong <u>base</u>.
