how many moles of nickel are in atoms are there in 9.00 X 10^9 Ni atoms
Answer:
1.49 x 10⁻¹⁴ moles Ni
Explanation:
To find the amount of moles in the sample, you need to multiply the amount of atoms by Avogadro's Number. This conversion is a ratio that describes how many atoms there are per every 1 mole. It is important to arrange the ratio in a way that allows for the cancellation of units (atoms should be in the denominator). The final answer should have 3 sig figs like the given value.
Avogadro's Number:
6.022 x 10²³ atoms = 1 mole
9.00 x 10⁹ atoms Ni 1 mole
--------------------------------- x -------------------------------- = 1.49 x 10⁻¹⁴ moles Ni

What is the volume of the sapphire?
The volume of the sapphire, given the data from the question is 1.3 mL
Data obtained from the questionFrom the question given above the following data were obtained:
Volume of water = 4.9 mLVolume of water + sapphire = 6.2 mLVolume of sapphire =?How to determine the volume of the sapphireThe volume of the sapphire can be obtained by using the displacement method as follow:
Volume of sapphire = (Volume of water + sapphire) - (Volume of water)
Volume of sapphire = 6.2 - 4.9

A. H2
B. H2O
C.O2
D. H
Answer:
I believe H2.

It's H2 because there are two electrons on there being share by 2 atoms.
Since Hydrogen can only get a maximum of 2 electrons and no other atoms are present, that is why it's H2.
What orbitals would be present in principal energy level two?
There are 4 orbitals in the principal energy level two. These are: one 2s orbitals and three 2p orbitals (2px, 2py and 2pz).
Principal energy level indicates the energy shell outside the nucleus in which an electron is located. There are 4 principal energy levels. These are: s (sharp), p (principal), d (diffuse) and f (fundamental). The principal energy level can be denoted by the letter n.
Orbital is a function. It describes the behavior and the location of an electron in an atom. The orbitals for any energy level are calculated using the formula n² (where n is the number of orbitals). Hence for energy level 2, the number if orbitals = 2² = 4. Now s has only one orbitals and p has three, therefore a total of four orbitals.

If a sample of carbon dioxide is at − 60.0 ∘C and 0.50 atm and warm to 30.0 ∘C and 0.50 atm, then there will be no phase transition in the sample is a True statement.
Phase Transition:
The three main states of matter are Solid, Liquid, and gas. A phase transition occurs from one state of matter to another when energy is supplied or cut.When energy is supplied to the molecules, solid converts to liquid, and liquid converts to gas. Then, the energy increases the speed of the molecules, the density decreases and phase transition takes place.On the other hand, when the supply of energy is stopped from the molecules, the gas turns to liquid, and liquid converts to solid. Both the temperature and pressure are in the same phase.Therefore, there will be no phase transition in the sample. Hence, it is a true statement.

Ethyl alcohol, also known as ethanol, has a density of 0.79 g/mL. What is the volume, in quarts, of 1.95 kg of this alcohol?
Express your answer using two significant figures.
Taking into account the definition of density, the volume of 1.95 kg of alcohol is 2.6083 quarts.
Definition of densityDensity is a quantity that allows us to measure the amount of mass in a certain volume of a substance.
The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
density= mass÷ volume
It can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
Volume in this caseIn this case, you know that:
Density= 0.79 g/mLMass= 1.95 kg= 1950 gReplacing in the definition of density:
0.79 g/mL= 1950 g÷ volume
Solving:
0.79 g/mL ×volume= 1950 g
volume= 1950 g÷ 0.79 g/mL
volume= 2468.35 mL= 2.6083 quarts (being 1 mL= 0.00105669 quarts)
In summary, the volume of 1.95 kg of alcohol is 2.6083 quarts.

1. If a chemical reaction occurs and a solid reacts with a gas to form a new solid,
(2 Points)
the mass of the new solid substance increases because a substance in the gas state has mass and contributes
to the new substance's mass.
the mass of the new solid substance does not change because a substance in the gas state does not have
mass and therefore, will not contribute any new mass of the new substance.
it is difficult to determine if the new substance will increase in mass because it depends on the type of gas.
According to the law of conservation of mass, if a chemical reaction occurs and a solid reacts with a gas to form a new solid: (a) the mass of the new solid substance increases because a substance in the gas state has mass and contributes to the new substance's mass.
Law of conservation of mass states that, the mass can neither be created nor be destroyed in a chemical reaction, it can only be transferred rom one form to another or from the reactants to the products of a chemical reaction.

A carpet sells for $24.99 per square yard. What is the price of the carpet per square meter? How much will it cost to carpet an area of 1365 ft2?
The carpet sells for $24.99 per square yard, so the cost of the carpet per square meter area is $40,799.85.
What is the carpet area?The carpet area is that space in your home, which can be used for laying a carpet. It includes the thickness of the internal wall, but excludes the balcony or terrace.
Given that the price of the carpet is $24.99 per square yard, in the first step to convert the square yard to a square meter. 1 square yard = 0.836 square meters now in the second step, calculate the cost per square meter based on the relation in the above step we can write,0.836 square meters of carpet costs $24.99.
Therefore, the cost of 1 square meter of the carpet would cost of the carpet multiplied by one square meter and then divided by the unit in one square yard. From this, the price of the carpet per square meter is known. Price of the carpet per square meter = $24.99 * 1 sq meter/0.836 sq meter price of the carpet per square meter= $29.89. Now we have to find the Cost of the carpet area.
Cost of carpet area = $24.99* 1365 = $40,799.85.
Thus, the Cost of carpet area is $40,799.85.

Explanation:
Firstly, we need to know how many atoms of [tex]NH_{3}[/tex] are there in 3 moles of [tex]NH_{3}[/tex].
We know that there is [tex]6.022[/tex] × [tex]10^{23}[/tex] atoms in a mole of any substance.
[tex]6.022[/tex] × [tex]10^{23}[/tex] is Avogadro's Constant
[tex]6.022[/tex] × [tex]10^{23}[/tex] × 3 = [tex]1.8066[/tex] × [tex]10^{24}[/tex]
Therefore in 3 moles of ammonia, there are [tex]1.8066[/tex] × [tex]10^{24}[/tex] atoms.
Next, you should determine how many molecules of an element is present in ammonia.
There is 1 Nitrogen molecule and 3 Hydrogen molecules for every mole of ammonia.
Finally, since we know 3 moles of ammonia contains [tex]1.8066[/tex] × [tex]10^{24}[/tex] atoms, we just have to multiply accordingly to get the individual amount of atoms of an element a compound has.
For Nitrogen :
1 × [tex]1.8066[/tex] × [tex]10^{24}[/tex] = [tex]1.8066[/tex] × [tex]10^{24}[/tex] atoms of nitrogen
For Hydrogen :
3 × [tex]1.8066[/tex] × [tex]10^{24}[/tex] = [tex]5.4198[/tex] × [tex]10^{24}[/tex] atoms of hydrogen
Therefore, there is [tex]5.4198[/tex] × [tex]10^{24}[/tex] hydrogen atoms in 3 moles of ammonia.

A light wave which has a frequency of 5 x 1014 Hz and a speed of 3 × 10 m/s has wavelength is 0.6 × 10^-6.
Wavelength is defined as the separation between two identical points (adjacent crests) in adjacent cycles as the signal travels through space or along a wire.The number of cycles or vibrations that a body in periodic motion experiences during one unit of time, as well as the number of waves that pass a fixed point in a unit of time is called Frequency. Frequency is expressed in Hertz (Hz).Speed of light, the rate at which light waves move through various substances. Specifically, the speed of light in a vacuum is presently calculated to be 3 × 10⁸ m/s.Frequency of light wave = ν = 5 × 10¹⁴ Hz
Speed of light c = 3 × 10⁸ m/s
