The house wiring should be done parallel because, in parallel connection there will be more advantages than a series connection.

Let a house is wired in series and it contains a fan, tube light, TV, refrigerator. All the devices are connected in series. Now, due to some disturbance the fan speed working or it burned. Then since the connection was a series, due to one appliance failure causes the whole circuit to fail. If it is burned that means it making an open circiut. Then there will be no current flow in the circuit.

Now if it was a parallel connection as we know already, the parallel connection is nothing but individual appliances connected to the same line by tappings. That means there's no dependency of one appliance on another. So if an appliance fail or burns it doesn't effects the remaining appliances. And there will be uninterrupted supply to the healthy appliances can be achieved.

That’s why we use parallel for house wiring

vekshin1

Answer:

<em>The three gases, in the three identical containers, will all have the same number of molecules</em>

Explanation:

If these three gases (Helium He, Neon Ne, and Oxygen O_{2}) are all contained in separate identical containers with the same volume. And they are all stored at the same temperature, and pressure. Then, they'll all contain the same number of molecules. This is in line with Avogadro's law which states that "Equal volume of all gases, at the same temperature and pressure, have the same number of molecules."

Dmitry_Shevchenko [17]

The <u>Mole</u> is the SI unit that expresses the amount of substance.

Mole is defined as - The mole is the amount of substance containing the same number of entities as there are in the 12 grams of Carbon - 12.

Mole is denoted by using symbol mol.

      Mole = 6.022 x 10²³ elementary entities.

These number of elementary entities in 1 mole is equal to or called as an Avogadro's number.  Mole is equal to 6.022 x 10²³ because this number of entity is same as in exactly 12 g of carbon-12.

It is a very important SI unit of measured which is used by the chemists. Moles are used in measuring in small or tiny things such as atoms, molecules and the other tiny particles.

How many moles of tungsten carbide will be produced if plenty of tungsten is reacted with 1.25 moles of carbon?
Tanya [424]

Answer:

1.25 moles of tungsten carbide

Explanation:

Tungsten carbide, WC, is a substance that is produced prom carbon and tungsten as follows:

W + C → WC

Based on the reaction, 1 mole of Carbon produce 1 mole of tungsten carbide. That means if 1.25 moles of carbon are added in excess of tungsten, the moles of tungsten carbide produced are:

Harry stores toxic chemical waste in a large steel tank that has only 15% of its volume underground. Jena lives in the wildernes
Anvisha [2.4K]

Answer:

Only Harry and Jena

Explanation:

Under federal regulations, an UST is any one or a combination of tanks such that the volume of an accumulation of regulated substances is 10% or more beneath the surface of the ground.

Any UST system holding a mixture of hazardous waste and other regulated substances are also are not covered by federal regulations regarding USTs.

Farm or residential tank of capacity more than 11 gallons used for storing motor fuel is covered by federal regulations regarding USTs.

According to the given question,

Only Harry and Jena are covered by federal regulations regarding USTs.

The pH of a cup of black coffee is 5 while the pH of glass of tomato juice is 4. Comparing the pH of the two liquids, the tomato
GREYUIT [131]
PH is the concentration of Hydrogen ions (shown as [H+]) in a solution. The scale for pH is 0-14, with 0 being very high acidity and 14 being low acidity (basic). The scale is a logarithmic scale, so this means that each number is 10 times stronger than the number that precedes it.

The pH of the tomato juice is 4, which is more acidic than the black coffee with a pH of 5. Since there is a difference of one number between the two (scale of 1), then this tells us that the concentration of Hydrogen ions in the tomato juice is ten times GREATER than the [H+] of the black coffee.
