Should a homeowner expect more caco3 buildup in hot water pipes or cold water pipes

1 answer:

5 0

Answer:
CaCO₃ built up in hot water pipes

Explanation:

The hardness of water is classified as;

Permanent Hard Water:
In this the mineral content cannot be removed by boiling. This water contains mainly following,

Calcium Sulfate CaSO₄

Calcium Chloride CaCl₂

Magnesium Sulfate MgSO₄

Magnesium Chloride MgCl₂

These salts does not precipitate out on heating water.

Temporary Hard Water:
In this water the mineral content can be removed by boiling. This water contains mainly following,

Calcium Bicarbonate Ca(HCO₃)₂

Calcium Carbonate CaCO₃

Magnesium Bicarbonate Mg(HCO₃)₂

Magnesium Carbonate MgCO₃

These salts does not precipitate out on heating water. i.e.

Ca(HCO₃)₂ -------heat------> CaCO₃ + CO₂ + H₂O

The CaCO₃ are formed in the form of scales.

Result:
Hence, we can say that that CaCO₃ built up in hot water pipes.

What state of matter is at 35 Celsius

Otrada [13]

Different forms of matter have different melting/boiling points. For example, at 100 degrees Celsius, H2O (water) will turn from lliquid to gas. But NaOH (table salt) doesn't even go from solid to liquid until some 800 degrees Celsius. So, in order to figure out which state matter is at 35 Celsius, you'd have to be more specific about what kind of matter...

the average kinetic energy of the particles in a gas increases as the temperature of the gas increases. explain

sveticcg [70]

Answer:

Explanation: Volume versus Temperature: Raising the temperature of a gas increases the average kinetic energy and therefore the rms speed (and the average speed) of the gas molecules. Hence as the temperature increases, the molecules collide with the walls of their containers more frequently and with greater force.

Explain how you would decide which represents a greater mass: 3.25 x 1022 atoms of Ca or 2.45 grams of Mg?

elena55 [62]

Answer:

You need to convert the number of atoms of Ca into mass in grams, using Avogadro's number and the atomic mass of Ca.

Explanation:

The amount of matter is measured in grams. Thus, you need to convert the number of atoms of Ca (calcium) into mass to compare with 2.45 grams of Mg.

To convert the atoms of calcium into mass, you divide by Avogadro's number, to obtain the number of moles of atoms, and then divide by the atomic mass of calcium.

1. Number of moles, n

$n=\dfrac{\text{number of atoms}}{\text{Avogadro's number}}\\ \\ \\ n=\dfrac{3.25\times 10^{22}}{6.022\times 10^{23}}=0.053969mol$

2. Mass

mass = number of moles × atomic mass

mass = 0.053969mol × 40.078g/mol = 2.16g

Then, 2.45 g of Mg represent a greaer mass than the 3.25 × 10²² atoms of Ca.
