Which state of matter has a definite volume but can change its shape?A.) Solid
B.)gas
C.)liquid
Which state of matter has a definite volume but can - 1

Answers

Answer 1
Answer:

Answer:

solid

Explanation:

because solid has a definite shape and volume
Answer 2
Answer:

Answer:

Liquid

Explanation:

This is because the intermolecular forces of attraction are strong enough to hold the molecules together but not so strong as to fix them into definite positions (as in solids). Instead, they possess fluidity and hence no definite shape.

Describe the capillary action in acetone compared to water

Answers

Capillary action is defined as the ability of a liquid to go up a narrow space without the help or opposition of external forces. One of the most important factors affecting capillary action is the intermolecular forces within a substance. The higher the IMF, the greater the capillary action. The H-bonding in water gives it greater IMF than acetone, so water has greater capillary action.

Describe the chemical process of fermentation.

Answers

Fermentation is a metabolic process. The molecules like glucose are breaks down anaerobically.

What is Fermentation ?

Fermentation is a metabolic process which converts sugars to alcohol, acids or gases. Fermentation is observed in bacteria,yeast cell and also in the muscle of animals.  An Example is lactate fermentation which produces lactic acid.

What is Chemical process of fermentation ?

Fermentation is a chemical process in which molecules like glucose are breaks down anaerobically. Fermentation is chemical change. In chemical changea new substance is formed.

Thus, from above conclusion we can say that Fermentation is a metabolic process. The molecules like glucose are breaks down anaerobically.

Answer:

Fermentation is a chemical process in which complex organic molecules are broken down into simpler compounds like ethanol. This process is catalyzed by certain enzymes. Enzymes are complex chemical catalysts produced by living cells. The sugars used for fermentation are often formed by enzymatic decomposition of starches from corn, potatoes, rice, or grain.

Calculate the energy required to melt 12.4 g of ice at 0 oC. The molar heat of fusion for ice is 6.02 kJ/mol.

Answers

Answer:

Energy required is 4.147 kj.

Explanation:

Given data:

Mass of ice = 12.4 g

Temperature = 0°C

Molar heat fusion for ice = 6.02 kj/mol

Energy required to melt = ?

Solution:

Formula:

q = n ×ΔH

q = heat

n = number of moles

ΔH = enthalpy

First of all we will calculate the number of moles.

Number of moles = mass/ molar mass

Number of moles = 12.4 g/ 18 g/mol

Number of moles = 0.69 mol

Now we will put the values in formula.

q = n × ΔH

q = 0.69 mol × 6.02 kj/mol

q = 4.147 kj

What property of an atom determines its general reactivity?

Answers

The Chemical reactivity of metals varies with your eletropositividade, so the more eletropositivo is the most reactive element is metal. The most reactive metals are those that have great tendency to lose electrons and  therefore form positive ions with more ease.

An unknown substance turns blue litmus paper to red. Which additional test could be used to confirm the substance’s identity? It should turn phenolphthalein from colorless to pink because it is a base. It should turn phenolphthalein from pink to colorless because it is a base. It should turn methyl orange to orange because it is an acid. It should turn methyl orange to red because it is an acid.

Answers

The substance that turns blue litmus red should turn methyl orange to red because it is an acid.

What is an acid?

An acid is a substance that produces hydrogen ions as the only positive ions when dissolved in water.

Properties of acid include :

  • acids turn blue litmus red
  • are corrosive
  • are sour in taste

Therefore, the substance that turns blue litmus red is an acid:

It should turn methyl orange to red because it is an acid.
