A substance is called malleable

Chemistry
2 answers:
NeTakaya3 years ago

Answer: Malleability is a substance's ability to deform under pressure (compressive stress). If malleable, a material may be flattened into thin sheets by hammering or rolling. Malleable materials can be flattened into metal leaf. Examples of malleable metals are gold, iron, aluminum, copper, silver, and lead.

Explanation: This what you needed?

Answer:

Malleability is a substance's ability to deform under pressure (compressive stress). Examples of malleable metals are gold, iron, aluminum, copper, silver, and lead. Gold and silver are highly malleable. When a piece of hot iron is hammered it takes the shape of a sheet.

State two conditions necessary for an esterification reaction to take place​
nadya68 [22]

Explanation:

Esterification occurs when a carboxylic acid reacts with an alcohol. This reaction can only occur in the presence of an acid catalyst and heat. It takes a lot of energy to remove the -OH from the carboxylic acid, so a catalyst and heat are needed to produce the necessary energy.

Once magnesium (Mg) gives up electron(s) to become an ion, it will become (Hint - it gives up electrons. What would happen to an
MaRussiya [10]

Answer:

B.) a cation that is smaller than the original atom

Explanation:

When the atoms of an element gains or loses electrons, it becomes charged. This charged atom is called an ION. An ion can either be a CATION or ANION depending on whether the atom loses electrons to become positively charged (cation) or gains electrons to become negatively charged (anion).

In this case, magnesium (Mg) atom gives up or loses electron(s) to become an ion, it will become positively charged and hence called a CATION. However, since it loses electrons in its atom, it becomes SMALLER than the original magnesium atom. This is because the electrons left in the atom becomes more attracted to the nucleus and decreases the ionic radius.

Can someone help me with this?
Rudik [331]
Yeah so you have to start of with converting your first two values into moles (forget the third one)

97.5 g NO * 1 mol/30.01 g NO = 3.25 moles NO

88.0 g O2 * 1 mol/16.00 g O2 = 5.5 moles O2

now we can find the limiting reactant by checking for the amount of product each reactant should give us by using molar ratios

3.25 mol NO * 2 mol NO2/2 mol NO = 3.25 mol NO2

5.5 mol O2 * 2 mol NO2/ 1 mol O2 = 11

so NO is the limiting reactant since it produces less product/gets used up quicker

3.25 mol NO * 2 mol NO2/2molNO = 3.25 mol NO2

so this is our theoretical yield and the question provides us with the actual yield (2.68 moles). since the actual yield is given in moles, we don't have to convert to grams. our percent yield formula goes like: actual yield/theoretical yield * 100

2.68 mol/3.25 mol * 100 = 82.46%

A 20 ounce bottle of soda provides a total of 300. calories. how many kilojoules are in the soda
Yuri [45]

The ratio which denotes the relation between the two different units is said to conversion factors.

According to conversion factors, the relation between calorie and kilojoule is given as, one Calorie is equal to 4.184 kJ.

1 Cal = 4.184 kJ

Now, according to above relation, convert 300 calories into kilojoules.

300 calories =300 Cal\times \frac{4.184 kJ}{1 Cal}

= 1255.2 kJ

\simeq 1255 kJ

Thus, kilojoules present in soda is equal to 1255 kJ

satela [25.4K]
This is likely the phase change from solid to gas, or sublimation. Gas molecules have more random motion and higher kinetic energies than liquid molecules, so the change is sublimation.
