What phases are most common at high temperatures

Chemistry
1 answer:
Nikitich [7]3 years ago
5 0

Answer:

Liquids and gases.

For most substances, when heated to a high enough temperature, the molecules begin moving faster which results in its liquid or gas state.

Conduction is a method of energy transfer within Earth’s systems. Describe an example of conduction, including where the energy
Varvara68 [4.7K]

Answer:

Conduction is the transfer of thermal energy from one molecule to another within an object. Conduction also happens between two objects in direct contact if they have different temperatures. The hotter molecule vibrates because of the added heat. This vibration and movement transfer the energy to the surrounding molecules. The transfer of energy continues until all the molecules have the same temperature.

Conduction takes place in solids, liquids, and gases. However, it happens fastest in solids because the molecules in solids are closely packed.

What are the major organic products are formed when the following compounds react with methylmagnesium bromide (CH3MgBr), follow
Sliva [168]

Answer:

Major organic products are- (a) propan-1-ol and (b) 2-methylpropan-2-ol

Explanation:

methyl magnesium bromide gives nucleophilic addition reaction with carbonyl group. Because methyl magnesium bromide is a strong nucleophile and carbonyl group is a strong electrophilic center.

Propanal contains an aldehyde group and propanone contains a ketone group. hence they both give nucleophilic addition with methyl magnesium bromide.

Dilute acid is added to protonate the alkoxide produced during nucleophilic addition.

Reactions are shown below.

How many atoms of gold are in 112 grams of gold?
ikadub [295]
Atomic <span>mass gold  = 196.96 u.m.a

196.96 g ------------------ 6.02x10</span>²³ atoms
112 g ---------------------- ( atoms)

atoms = 112 x ( 6.02x10²³) / 196.96

atoms = 6.74x10²⁵ / 196.96

= 3.42x10²³ atoms

hope this helps!

If a 0.4856 gram sample of khp is dissolved in sufficient water to prepare 250 ml of solution, and 25 ml of the solution require
dangina [55]

Mass of potassium hydrogen pthalate KHP is 0.4856 g, its molar mass is 204.22 g/mol, number of moles of KHP can be calculated as follows:

n=\frac{m}{M}

Here, m is mass and M is molar mass, putting the values,

n=\frac{0.4856 g}{204.22 g/mol}=0.00237 mol

This will be number of moles of NaOH at equivalent point.

Detailed calculations:

Molarity is defined as number of moles in 1 L of solution, for 250 mL of solution, molarity will be:

M=\frac{0.00237 mol}{250 \times 10^{-3}L}=0.009511 M

For 25 mL, apply dilution law as follows:

M_{1}V_{1}=M_{2}V_{2}

Putting the values,

0.009511\times 250=M_{2}\times 25 mL

On rearranging,

M_{2}=\frac{0.009511\times 250}{25}=0.09511 M

Convert molarity into number of moles,

n=M\times V=0.09511 mol/L\times 25\times 10^{-3}L=0.00237 mol

At equivalent point, number of moles of KHP will be equal to NaOH, thus, number of moles of NaOH will be 0.00237 mol.

Calculation for molarity:

Volume of NaOH is 18.75 mL, thus, molarity can be calculated as follows:

M=\frac{n}{V}

Putting the values,

M=\frac{0.00237 mol}{18.75\times 10^{-3}L}=0.1264 M

Therefore, molarity of NaOH is 0.1264 M
