How many molecules are contained in 1.55 moles of methane, CH 4 ?

Chemistry
1 answer:
Korolek [52]2 years ago
5 0

Avogadro's law states that in one mole of a substance, there are 6.022 \times 10^{23} molecules.

This means that in 1.55 moles, there are 1.55(6.022 \times 10^{23})=\boxed{9.33 \times 10^{23} \text{( to 3 sf)}}

Answer: theres alot let me explain...

Explanation:

Protein denaturation is what makes eggs solidify, collagen break down and convert to gelatin in slow-cooked meat, fish and chicken become more opaque, and all meats firm up and change color. This is primarily achieved by applying heat, but can also occur in the presence of acidic and basic ingredients.

The Maillard reaction is the primary effect taking place in “browning”, and produces more flavor compounds, resulting in more complex flavors in food that we generally find enjoyable. It involves reaction between amino acids (proteins) and a certain class of sugars called reducing sugars — mostly the monosaccharides, such as glucose and fructose.

Caramelization is a secondary browning effect that occurs in foods with sugar content, even though all browning is often referred to as “caramelizing”. It mostly takes place at higher temperatures than Maillard reaction (with the notable exception of fructose).

Pyrolysis, or thermal decomposition (chemical breakdown) begins at higher temperatures. While caramelization is technically in this category, the main effect of this reaction is carbonization. This is what we generally mean when we talk about “burning” food, even though no combustion has taken place. It’s also what happens when we cause oil to smoke and darken. In small, controlled amounts, this can still provide desirable flavors, such as char on the outside of meat and contributing to “wok hei” in stir frying — the latter of which does involve some combustion.

Acid-base reactions produce carbon dioxide, which creates the rise in quick breads such as biscuits. These often occur at room temperature, but some also don’t occur until higher temperatures — which is how “double-acting” baking powder works.

Gluten formation occurs when you mix flour and water, resulting in stretchy doughs and fluffy baked goods. This occurs easily at room temperature.

Paha777 [63]

Answer:

ionize

Explanation:

Acids are chemical substances that lose/donate their hydrogen ion (H+) when they react with water. This property of acids is termed IONIZATION. In a chemical reaction involving acids and bases, acids release their proton or hydrogen ion (H+) in the presence of water solutions to form a conjugate base, which is usually an anion.

For example, in the chemical reaction;

HX + H20 -------> X- + H30+

HX is the acid because it loses its electron to water and forms the anion, X-, which is the conjugate base. Hence, it can be said that acid HX ionizes in water.

A ________ reaction occurs when one compound reacts and is broken down into different elements or simpler compounds?
faust18 [17]

Answer: decomposition

Explanation:

1 . Combustion is a type of chemical reaction in which a hydrocarbon reacts with oxygen to form carbon dioxide ans water along with liberation of large amount of energy.

2. Decomposition is a type of chemical reaction in which a single reactant gives two or more than two products.

CaCO_3\rightarrow CaO+CO_2

3. Single replacement is a type of chemical reaction in which a more reactive element displaces the less reactive element from its slat solution.

4. Synthesis is a type of chemical reaction in which two or more than two reactants combine together to give a single product.
