Answer:

43.2 g of table salt occupies 20.0 cm2of space- Appropriate for calculating density

150 g of iron density of iron 79.0 g/cm3- Appropriate for calculating volume

21.0 mL of methanol density of methanol 0.79g/mL - Appropriate for calculating mass

3.00 g of white pine, density of white pine 0.40 g/cm3- Appropriate for calculating volume

5.00 cm,3 of table salt weighs 10.8g-Appropriate for calculating density

Explanation:

Density is defined as mass per unit volume. Hence in science;

Density= mass/volume

When mass and volume are both given, the information can be used to determine the density of a given substance.

When volume and density are both given, the information can be used to determine the mass of a given substance.

When the mass and density of a substance are both given, the information can be used to determine the volume of the substance.

Hence the answers given above.

lakkis [162]
<span>Conductance gives a more accurate method to determine the salt concentration of a solution.Conductivity would be used with conductors such as metals that include copper and silver.Conductivity is a measure of water's capability to pass electrical flow. This ability is directly related to the concentration of ions in the water. These conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds</span>

Sergeu [11.5K]

Answer:

Solution given:

e) The heating of sodium carbonate to produces sodium oxide and carbon dioxide

Solution given:

<u>Balanced</u><u> </u><u>chemical</u><u> </u><u>equation</u><u>:</u>

\boxed{\bold{\green{Na_{2}CO_{2} +heat \rightarrow Na_{2}O +CO_{2}}}}

<u>when sodium carbonate is heated it decomposed and form sodium oxide and carbon dioxide</u>

<u>f</u>) chromium (III) hydroxide plus sulfuric acid

<u>Balanced chemical equation:</u>

\boxed{\bold{\green{2Cr(OH)_{3}+ 3H_{2}SO_{4} → Cr_{2}(SO_{4})_{3} + 6H_{2}O}}}

<u>When chromium (III) hydroxide react with sulfuric acid double displacement takes place and forms produce chromium(III) sulfate and water.</u>

g) aluminum metal plus chlorine gas

HELP! THIS IS SCIENCE
Alexxx [7]
This is known as Rutherford's gold foil experiment. To align with J.J Thompson's Plum Pudding Model, he expects a beam of alpha particles to just pass through the gold foil undisturbed. However, some were deflected at certain angles. Alpha particles are positive, so it would just go straight through the nucleus, but will deflect if it hits the electrons. <em>Therefore, the answer is: </em><span><em>Particles that struck the nucleus went straight.</em></span>
