Answer:

GRAPHENE is a single layer of graphite

Explanation:

each carbon atom bonded to 3 other carbon atoms forming a hexagonal lattice

Answer:

731.5j.

Explanation:

Basic Formula : Q = mcT.

Q - Heat gained or lost.

m - mass of the given substance.

c - specific heat capacity.

T - Change in temperature ( it often has a delta(triangle) before it.

so now we are directly asked to find the heat.

Q = mcT

m= 5g

c = 4.18

but T = 35k which means 35 kelvin.

why? because you will need to convert the two given initial and final temperatures inorder to cancel the unit kelvin out from the formula above. the target is simply to make the unit J - joule be left alone.

now We convert celsius temperature to kelvin by adding a constant of 273.15 approximately 273.

therefore - Tk = Tc + 273

which will be equivalent to 295k for the initial temperature and 330k for the final.

now granted...keep in mind to use the CHANGE in temperature which is the difference of the 2 kelvin temperatures we just converted

so T = 330k - 295k = 35k

then just substitute everything in the very 1st formula i stated above.

Q = mcT = 5 x 4.18 x 35 = 731.5 J

peace to you.

If a solid object is taken from Earth far into space, which of the following measurements of the object will change the most?

A. density

B. mass

C. volume

D. weight

option D. weight

Because the gravity of the planet/object changes, the weight of the object changes when you move it away from the earth or place it on another planet.

However, the mass of the object remains the same regardless of whether it is on Earth or outer space.

Answer:

1.22gram of hydrogen is needed to react

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore,  0.40 g mass of hydrogen is needed to react with 32 g of copper oxide.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically,

CuO + H[tex]_2[/tex]→ Cu + H[tex]_2[/tex]O

mole of copper oxide=  32 /79.54

                                    =0.40 mole

The mole ratio between copper oxide and hydrogen is 1:1

mole of hydrogen= 0.40 mole

mass of hydrogen = 0.40 mole×1g/mol

                              = 0.40 g

Therefore, 0.40 g mass of hydrogen is needed to react with 32 g of copper oxide.

The unusual chemical properties of water is due to its polar covalent bond.

When atoms with differing electronegativities are shared between two atoms in such a covalent link, the result would be a polar covalent bond.

Water is a kind of mixture of hydrogen and oxygen . Its chemical formula will be [tex]H_{2}O[/tex].

Along with its polar covalent connections, water displays a variety of interesting features. Because oxygen has a higher electronegativity than hydrogen, electron pairs were drawn closer to the oxygen atom, causing it to be partially negatively charged. As a result, both hydrogen atoms acquire a slightly positive charge.

Therefore, polar covalent bond will be responsible for unusual chemical properties of water.

The energy of a single photon of this frequency is 1.638 × 10⁻¹⁸ J

Using Planck's equation, the energy of the photon E = hf where h = Planck's constant = 6.63 × 10⁻³⁴ Js and f = frequency of ultraviolet light = 2.47 × 10⁻¹⁵ Hz.

Substituting the values of the variables into the equation, we have

E = hf

E = 6.63 × 10⁻³⁴ Js × 2.47 × 10¹⁵ Hz.

E = 16.3761 × 10⁻¹⁹ J

E = 1.63761 × 10⁻¹⁸ J

E ≅ 1.638 × 10⁻¹⁸ J

So, the energy of a single photon of this frequency is 1.638 × 10⁻¹⁸ J

Melted ionic compounds

Explanation:

This is because the ions have dissociated and for electricity to pass through a substance it is important that the substance must have ions present in it.

Answer:

92.4%

Explanation:

Assume 100g of the cathode material. The LiCoO2 cathode has 7.09 g of Li.  If half of Li migrates during charging, 3.55g Li migrates. 100g of the LiMn2O4 cathode contain 3.84g of Li. The fraction of lithium in LiMn2O4 that would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode:

(3.55g/ 3.84g ) * 100% = 92.4%

From electrolysis, 92.4% would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode.

Electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potential.

Answer:humans have put ridiculous amounts of carbon dioxide into the atmosphereThese events are linked to the mass burning of fossil fuels to meet an increase in human demand

So the answer is True

Explanation:

Burning fossil fuels, such as coal and oil, has increased the quantity of greenhouse gases in our atmosphere since the Industrial Revolution began around 1750.

Atmosphere is defined as a layer of gas that surrounds a planet and is kept there by the gravitational pull of the planetary body. The atmosphere of Earth includes five primary layers and a number of minor ones.

Industrial revolution is defined as the transition of an economy based on agriculture and handicrafts to one driven by industry and machine production. The causes of industrial revolution are the advent of capitalism, European imperialism, efforts to mine coal, and the effects of the Agricultural Revolution are some of the factors that historians have recognized as contributing to the Industrial Revolution.

Thus, burning fossil fuels, such as coal and oil, has increased the quantity of greenhouse gases in our atmosphere since the Industrial Revolution began around 1750.

this is because the combining capacity, ie valency, of Pb is 2 of which NO3 is 1. So, when they will combine by cross method, the compound become Pb(NO3)2 (lead II nitrate).

After beginning the experiment with a saturated solution, then increasing the heat, we will be left with an unsaturated solution.

To obtain the saturated solution, we must dissolve sugar in the water. We can say that the solution has become saturated when the solution is no longer able to dissolve more sugar. It has reached its capacity for the solute that it can dissolve in these conditions.

However, the temperature of a solution has an effect on the dissolving limit of the solution. That is, when a solution is heated it becomes able to dissolve more solute. Therefore, if we were to heat a saturated solution, it will be able to dissolve more solute and therefore will no longer be at its limit, meaning it is no longer a saturated solution. It has become unsaturated.
