5. Using the terms: metal and nonmetal, describe what types of atoms make up each type of<br> bond.
Elis [28]

Answer:

See the answer below, please.

Explanation:

The bonds formed between metals and nonmetals are called ionics. These occur between atoms with electronegativity difference. Example: NaCl (Sodium Chloride)

Instead, covalent bonds are formed between two nonmetals (one or more electron pairs are shared). Example: H202 (hydrogen peroxide).

In the case of metal formed bonds, they are called metallic.

What is the mass in 6.34x10^23 molecules of calcium chloride
Liono4ka [1.6K]

Answer : The mass of calcium chloride is, 116.84 grams

Solution : Given,

Molar mass of calcium chloride, CaCl_2 = 110.98 g/mole

Number of molecules of calcium chloride = 6.34\times 10^{23}

As we know that,

1 mole of calcium chloride contains 6.022\times 10^{23} molecules of calcium chloride

or,

1 mole of calcium chloride contains 110.98 grams of calcium chloride

Or, we can say that

As, 6.022\times 10^{23} molecules of calcium chloride present in 110.98 grams of calcium chloride

So, 6.34\times 10^{23} molecules of calcium chloride present in \frac{6.34\times 10^{23}}{6.022\times 10^{23}}\times 110.98=116.84grams of calcium chloride

Therefore, the mass of calcium chloride is, 116.84 grams

One molecule of sucrose is burned with oxygen to make carbon dioxide and water.

Disaccharide sugar sucrose is composed of glucose and fructose. It is produced naturally by plants and is the main component of white sugar. C₁₂H₂₂O₁₁ is the chemical formula for it.

Extraction and refining sucrose for human use can be done from either sugarcane or sugar beet. Raw sugar is created from crushing the cane, which is consistently delivered to other sectors to be refined into pure sucrose. Sugar mills generally are located in the tropical regions near the sugarcane plantations.

<em>                    C₁₂H₂₂O₁₁ + 12O₂  →  12CO₂ + 11H₂O</em>

When one molecule of sucrose is burnt, we get 12 carbon dioxide molecules.

To learn more about sucrose,
