Explanation:

Sonoluminescence is a phenomenon in which small gas bubbles burst to produce light when intense sound wave is introduced. Thus, it can be said that sound energy is converted to light energy here. This is similar to the process of how fire crackers work except that sonoluminescence occurs in a liquid medium while firecrackers work in solid media. In firecrackers, when the tip is lit with fire, the initial explosion is caused by the expansion of some nitrogen and carbon present in some constituent compounds, this explosion produces heat which causes some other constituent chemicals in the firecracker to quickly react and produce light. Thus, this can also be said to convert sound energy to light energy and are thus similar to what occurs in sonoluminescence.

Explanation:

There are the two elements that make water

Answer:

It is an ionic bond.

Explanation:

Ionic bonds occur when a metal and a nonmetal combine, while covalent bonds occur between two nonmetals. Lithium is a metal and sulfur is a nonmetal.

Answer:

Aluminum iodide (AlI₃)

Explanation:

The synthesis reaction of aluminum (Al) and iodine (I) can be illustrated as shown below:

Aluminium exhibit trivalent positive ion (Al³⁺)

Iodine exhibit univalent negative ion (I¯)

During reaction, there will be an exchange of ion as shown below:

Al³⁺ + I¯ —> AlI₃

Thus, we can write the balanced equation for the reaction as follow:

Al + I₂ —› AlI₃

There are 2 atoms of I on the left side and 3 atoms on the right side. It can be balance by putting 2 in front of AlI₃ and 3 in front of I₂ as shown below:

Al + 3I₂ —› 2AlI₃

There are 2 atoms of Al on the right side and 1 atom on the left side. It can be balance by putting 2 in front of Al as shown below:

2Al + 3I₂ —› 2AlI₃

Thus the equation is balanced.

The product on the reaction is aluminum iodide (AlI₃)

The correct answer is B. Metalloids

Explanation:

In this periodic table, the green boxes include elements such as Boron (B), Arsenic (As), and Antimony (Sb). All these elements are known in chemistry as semimetals or metalloids. This classification is because these elements cannot be completely classified into metals or non-metals. Moreover, they all display similar properties including some level of conductivity, malleability, and solid-state. According to this, the correct answer is B.

The compound V₂O₅ has a Seebeck coefficient at a temperature of 50 °C of -990 μV/K.

Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.

Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:

1)Molecular compounds where in atoms are joined by covalent bonds.

2) ionic compounds where atoms are joined by ionic bond.

3)Inter-metallic compounds where atoms are held by metallic bonds

4) co-ordination complexes where atoms are held by co-ordinate bonds.

They have a unique chemical structure held together by chemical bonds .Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

Explanation:

From this equation, 2 grams are produced.

The mass of H₂O produced from the reaction is 2.25 g

We'll begin by calculating the mass of N₂H₄ that reacted and the mass of H₂O produced from the balanced equation.

N₂H₄ + 3O₂ —> 2NO₂ + 2H₂O

Molar mass of N₂H₄ = (2×14) +(4×1) = 32 g/mol

Mass of N₂H₄ from the balanced equation = 1 × 32 = 32 g

Molar mass of H₂O = (2×1) + 16 = 18 g/mol

Mass of H₂O from the balanced equation = 2 × 18 = 36 g

SUMMARY

From the balanced equation above,

32 g of N₂H₄ reacted to produce 36 g of H₂O.

From the balanced equation above,

, 32 g of N₂H₄ reacted to produce 36 g of H₂O.

Therefore,

2 g of N₂H₄ will react to produce = (2 × 36) / 32 = 2.25 g of H₂O

Thus, the mass of H₂O produced from the reaction is 2.25 g

Answer: well i guess we can say that  is a scale used to specify the acidity or basicity of an aqueous solution and it is important to keep ph of hot tub water between 7 and 7.6 because if it is not balanced the water  can negatively affect your tub.

Explanation:

pH is an extremely important chemical level to maintain in your spa's water chemistry. A high pH or a low pH will spell trouble for you and your spa. On the pH scale, a reading of 7.4-7.6 indicates perfectly balanced pH. Any number lower than 7.4 means that your water is now considered “acidic”.

Answer:

pH is a scale to measure the acidity or basicity of a substance such as water, it would be important to keep the pH of hot-tub water between 7 and 7.6 because if the acidity is too high, the walls of the hot-tub may be damaged, and if the pH is too low, the heating thing may get damaged.
