Explanation:

Answer:

No, it's a physical reaction.

Explanation:

A chemical change produces new chemical compounds, but combining water and powder is just mixing the powder with the water. It's not a new compound.

I don't know how to really explain, sorry :)

Answer:

Element- Aluminum

Element - Mercury

Compound - Ferrous Sulfate

Compound - Sucrose

Element - Carbon​

Explanation:

Element: an element is a pure substance which is composed of only one type of atoms and that cannot be split or broken down into any simpler pure substance.

Examples of elements include:

Aluminum - it is composed of only atoms of aluminium. Each atom has 13 protons

Mercury - it is composed of only atoms of mercury. Each atom has 80 protons

Carbon - it is composed of only atoms of carbon. Each atom has 6 protons

Compound: a compound is a pure substance that is composed of two or more types of atoms (elements) in a fixed and definite proportion and that cannot be split into component elements by simple physical methods but only by chemical methods. Examples of compound include:

Ferrous sulphate: It is composed of atoms of Iron, Sulfur and Oxygen

Sucrose: It is composed of atoms of Carbon, Hydrogen and Oxygen.

Answer:

As a result, to prepare 250 ml of 0.20M NaCl, take 50 ml of 1.0M NaCl solution and add 200 ml of water.

Explanation:

The number of atomic orbitals is the same for all elements in a period. Every element in the top row (the first period), for example, has only one orbital for its electrons. The electrons of all the elements in the second row (second period) have two orbitals. Every row adds an orbital as you progress down the table.

Decomposition reaction

Explanation:

2Ag₂O => 4Ag + O₂

As silver oxide is split into silver metal and oxygen gas, it can be classified as decomposition reaction.

Answer:

[tex]\huge\boxed{\sf 186.59\ L}[/tex]

Explanation:

Given that:

No. of moles = 8.33 mol

At STP, 1 mol. of all gases has a molar value of 22.4 dm³/mol

So,

Volume of 8.33 mol of N₂ gas:

= no. of moles x molar value

= 8.33 x 22.4

= 186.59 dm³

Since 1 dm³ = 1 L

So,

Volume = 186.59 L

Answer:

When coal is used to produce electricity , the heat energy is transformed into mechanical energy .

Explanation:

   Coal is one of the United States' most affordable and largest domestically produced energy sources. It is used to generate a significant quantity of our electricity, about 37%. Historically, producing power from coal has been correlated with a wide range of environmental impacts.

Water is converted into steam at a coal-fired steam plant, much like a nuclear plant, which in turn powers turbine generators to generate electricity. Here is how it operates in the process.

Without any pollution, the cooling water is returned to its source and the steam water is returned to the boiler to repeat the cycle.

Hence, the heat energy is transformed to the mechanical energy ,when coal is used to produce electricity.

The mass of nitrogen, N₂ required to react with 5.04 grams of oxygen O₂ is 1.76 grams

2N₂ + 5O₂ —> 2N₂O₅

Molar mass of N₂ = 2 × 14 = 28 g/mol

Mass of N₂ from the balanced equation = 2 × 28 = 56 g

Molar mass of O₂ = 2 × 16 = 32 g/mol

Mass of O₂ from the balanced equation = 5 × 32 = 160 g

SUMMARY

From the balanced equation above,

160 g of O₂ reacted with 56 g of N₂

From the balanced equation above,

160 g of O₂ reacted with 56 g of N₂

Therefore,

5.04 g of O₂ will react with = (5.04 × 56) / 160 = 1.76 g of N₂

Thus, 1.76 g of N₂ is needed for the reaction
