Answer:

Due its storing and holding ability.

Explanation:

It matter that the material from which the vat is made is metal because this vat is used for storing and holding liquids. Vat is a large container or tank that is used for storing or holding liquids in industrial sector. This vat is made of metal which increases its strength and durability. If the vat is made of wood or plastic so it can't hold huge amount of liquid or chemical due to its weak material so that's why it matters that the substance from which the vat is made is metal or not.

Answer: A heat energy of 50160 joules are required to heat 15 grams of ice from [tex]-200^{o}C[/tex] to [tex]1400^{o}C[/tex].

Explanation:

Given : mass of ice = 15 g

Convert grams into kg as follows,

[tex]1 g = 0.001 kg\\15 g = 15 g \times \frac{0.001 kg}{1 g}\\= 0.015 kg[/tex]

Initial temperature = [tex]-200^{o}C[/tex]

Final temperature = [tex]1400^{o}C[/tex]

Formula used to calculate the amount of heat energy is as follows.

[tex]q = m \times C \times (T_{2} - T_{1})[/tex]

where,

q = heat energy

m = mass of substance

C = specific heat of substance (ice here has C = [tex]2090 J/kg ^{o}C[/tex])

[tex]T_{1}[/tex] = initial temperature

[tex]T_{2}[/tex] = final temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times (T_{2} - T_{1})\\= 0.015 kg \times 2090 J/kg^{o}C \times [1400 - (-200)]^{o}C\\= 50160 J[/tex]

Thus, we can conclude that 50160 joules are required to heat 15 grams of ice from [tex]-200^{o}C[/tex] to [tex]1400^{o}C[/tex].

Answer:

Because carbohydrates are energy

Explanation:

Carbohydrates is best best nutrient for energy, turning into energy as soon as they are eaten. A rickshaw puller most likely needs quite a bit of energy to pedal all day without getting tired, so that's why they eat a carbohydrate rich diet.

Answer:

carbon electrode: delocalised electrons

molten mixture....: aluminium oxide ions

metal wire: Metal atoms

The free moving charged particles in the following substances are as follows;

Graphite, an allotrope of carbon has Delocalized (free-moving) electrons and these electrons serve to enable conductivity.

Although, cryolite is a bad conductor of electricity, when Molten Aluminium oxide and cryolite is used, the free moving Aluminium ions enable conductivity.

In metal wires, conductivity is solely the responsibility of metal ions.

Pottasium reacts with water vigorously and the reation is exothermic. The heat released causes the hydrogen released to ignite

Explanation:

Answer:

Now, the molar solubility of lead(II) phosphate in water is said to be equal to 6.2⋅10−12mol L−1 . This means that in one liter of water, presumably at room temperature, you can only hope to dissolve 6.2⋅10−12 moles of lead(II) phosphate.

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

Answer: A

Explanation:

5.0 g / 56 g/mol is the numerical expression that gives the number of moles in 5.0 g of CaO.

HOW TO FIND NUMBER OF MOLES:

CaO = 40g/mol + 16g/mol = 56g/mol

Number of moles = 5.0g ÷ 56g/mol

Therefore, 5.0 g / 56 g/mol is the numerical expression that gives the number of moles in 5.0 g of CaO.

A possible solution for maximizing the percentage of hydrogen in discarded wood is to design a machine that can collect more effectively all the gases and separate hydrogen from other gases.

Discarded wood and other products can still produce important elements nitrogen, methane, and hydrogen. This is possible through combustion that releases these elements in a gas.

This is a new method and it is still not completely developed. Due to this, the equipment is not as efficient as one would like, for example, all gases are initially collected together but this is a problem if only one gas is needed.

Based on this, a potential solution would be to create a machine that is more efficient in collecting and separating the gases.
