Answer:

We will use an acid-base indicator to see changes in colour depending on the pH  

Explanation:

The pH changes during a titration, so you could use an acid-base indicator to follow the changes in pH.

A is wrong. An acid-base titration does not usually form a solid, and it would be impractical to isolate a solid with a funnel.

B is wrong. There are no changes in mass.

C is wrong. Any changes in temperature would be too small to measure precisely with an ordinary thermometer.

How many grams are in 0.5 moles of C10H16?<br><br>Please show your work for marked brainliest!​
vagabundo [1.1K]

Answer:

68 g

Explanation:

Molar mass (C10H16) = 10*12.0 g/mol + 16*1.0 g/mol = (120+16)g/mol =

= 136 g/mol

m (C10H16) = n(C10H16)*M(C10H16) = 0.5 mol*136 g/mol = 68 g

n(C10H16) - number of moles of C10H16

M(C10H16) - molar mass of C10H16

Make the following conversions. Show your calculations.
Natalija [7]

Answer:

1. 500 cm = 5 m

2. 1000 g = 1 kg

3. 455 L = 45, 500 cL

4. 0.865 m = 0.00865 m or 8.65 * 10^-3 n

5. 33.5 cm = 335 mm

6. 0.0198 m = 19800 micrometers

7. 57.65 cg = 5.765 * 10^8 nanograms

8. 1000 L = 1 kl

9. 99 degrees F = 37.222 degrees C

Explanation:

1.  One meter = 100 centimeters

500 centimeters/ 100 centimeters = 5 meters

2. One kilogram = 1000 grams.

1000 grams/1000 grams = 1 kilogram

3. One Liter = 100 centiliters

455 liters * 100 centiliters = 45, 500 centiliters

4. One meter = 100 centimeters

0.865 centimeters/100 centimeters = 0.00865 meters

5. One centimeter = 10 millimeters

33.5 centimeters * 10 millimeters = 335 millimeters

6. One meter = 1.0 * 10^6 micrometers

0.0198 meters * 1 * 10^6 micrometers = 19800 micrometers.

7. One centigram = 1.0 * 10^7 nanograms

57.65 centigrams * 1 * 10^7 nanograms = 5.765 * 10^8 nanograms.

8. One kiloliter = 1000 L

1000 L/ 1000 L = 1 kiloliter

9. The formula for finding Celsius is 5/9(f - 32)

So 5/9(99 - 32) = x

5/9(67) = x

x = 335/9 or 37.222 degrees Celsius.

A continuous fractionating column is designed to separate a mixture of benzene
densk [106]

Answer:

in the fraction distillation method, two liquids such as benzene and toluene are produced from the mixture of benzene  and toluene.

Explanation:

Fractional distillation is a technique used in the industries for the separation of two or more liquids from one another. In this process liquid is heated, those liquid has lower boiling point will change into vapor form and collect in the upper chamber of fractional distillation while the liquid having higher boiling point also evaporates after sometime and keep it in another chamber. In the mixture of benzene  and toluene, the boiling point of benzene is lower so it evaporates earlier than toluene.

The table shows several useful salts formed from reactions between different acids and bases.
ollegr [7]

The two chemical formulas which will correctly complete the table for lithium fluoride are: A. HF, LiOH.

<h3>What is a chemical reaction?</h3>

A chemical reaction can be defined as a chemical process that involves the continuous transformation (rearrangement) of the ionic, atomic or molecular structure of a chemical element by breaking down and forming chemical bonds, in order to produce a new chemical compound while new bonds are formed.

This ultimately implies that, chemical bonds between atoms of a chemical element are broken and then new bonds are formed in all chemical reactions.

<h3>What is a neutralization reaction?</h3>

A neutralization reaction can be defined as a type of chemical reaction between an acid and a base, which typically leads to the formation of an ionic compound (salt) and water as end products as shown below:

LiOH(aq) + HF(aq) → LiF(s) + H₂O(l)

In this context, we can infer and logically deduce that the two chemical formulas which will correctly complete the table for lithium fluoride are HF and LiOH.
