Taking into account the definition of density, the volume of 1.95 kg of alcohol is 2.6083 quarts.

Density 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.

In this case, you know that:

Replacing 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.

The mass of H₂s present in 2.00 L of natural gas at 298 K is 0.002156 g.

The volume hydrogen sulfide in 2.00 L of natural gas at 298 K is calculated as follows:

Volume of hydrogen sulfide = percent composition * volume of natural gas

Volume of hydrogen sulfide = 0.07/100 * 2.00 L

Volume of hydrogen sulfide = 0.014 L

The given temperature is standard temperature.

Density of H₂s at STP is equal to 1.54 g/L.

mass of H₂s = density * volume

The de Broglie wavelength of the bullet traveling at 1649 miles per hour is  1.3 x 10^34 m.

The  wavelength that is associated with an object in relation to its quantum and mass is known as de Broglie wavelength.

The particles de Broglie wavelength is inversely proportional to its force.

de Broglie wavelength is expressed as : ^ = h/mv

Where ^ is wavelength, h is plank constant, m is mass and v is velocity.

1 miles = 1.60934 km

So  1649 miles = 2653.8 km

Then 2653.8 x 1000/ 60x60 = 737.2 ms -1.

The momentum  of bullet is p = mv = 0.00693kg x 737.2 ms-1

                                                          = 5.109 kg/ms

Now, de Broglie wavelength = h/p = 6.63 x 10^-34 / 5.109 kg/ms

                                                           =  1.3 x 10^34 m

Thus, de Broglie wavelength of the bullet traveling at 1649 miles per hour is  1.3 x 10^34 m.

A. Geranium plant is sun loving plant because it showed maximum growth in full sun condition. The growth gradually decreases with the availability of sunlight. In full shade Geranium showed only 10% growth.

B. Impatiens plant showed its maximum growth in partial shade condition. The growth of only 40% occurs in dappled sun condition. In partial sun and full shade conditions it shows only 30% growth.  Full sun is harmful for impatiens as it showed only 10% growth.

C. Fuchsia  also show maximum growth in partial shade condition. It showed gradual decrease in growth in dappled sun, full shade, partial sun, and full sun respectively.

D. Trillium is shade loving plant because it shows maximum growth in full shade. It shows the lowest growth in full sun which gradually increases in partial sun, partial shade, dappled sun and full shade respectively.

Igneous rocks are broken down into sediments which are then compressed by forces of water, wind to form sedimentary rocks.

They are the types of rocks which are formed as a result of accumulation of minerals or organic particles at the surface of the earth.Sedimentation is the name given to a collective process which cause the particles to settle.

The study of sedimentary rocks is useful in civil engineering and as important sources of coal, fossil fuels and ores.The color of sedimentary rock is often determined by iron content and sometimes due to the presence of organic matter.

They are classified based on origin in to 4 types which are clastic, biochemical ,chemical and other sedimentary rocks.While based on composition they are classified as siliciclastic,carbonate ,evaporite,organic rich,siliceous ,iron-rich and phosphatic sedimentary rocks.

Answer: 0.66 g/mL

Explanation: The formula for density is d= m/v where m=mass and v=volume.

The mass was given in the problem, m= 1.32kg

The volume was also given in the problem, v= 2.0L

d= m/v ---> d= 1.32kg/2.0L ---> d=0.66kg/L

The problem calls for the answer to be written in g/mL, so we must convert the units. 1 kg contains 1000g and 1 L contains 1000 mL.

1000g/1000mL = 1 so the units change but the 0.66 does not. Therefore, your answer is 0.66g/mL (Two significant figures because 2.0 only has 2 significant figures).

[tex]5.4198[/tex] × [tex]10^{24}[/tex] atoms of hydrogen

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.

The oxide contains 22.24% O by mass, so the identity of the metal as a chemical symbol is lead (Pb).

A substance with high electrical conductivity, luster, and malleability, which readily loses electrons to form positive ions (cations) are called metals.

Mass percentage of oxygen in the oxide, i.e.,

ω(O) divided by 100 ω(O)

=22.24% ÷ 100%.

Mass percentage of oxygen in the oxide, i.e .ω(O) = 0.2224

Now the mass percentage of oxygen in the oxide multiplied by 100 ten we get the mass of oxygen in the oxide. If we take 100 grams of compound:

1) m(O) = ω(O) * 100 g.

Mass of oxygen in the oxide, i.e. m(O) = 0.2224 * 100 g.

Mass of oxygen in the oxide. i.e., m(O) =22.24g

Amount of oxygen, i.e.,

n(O) = mass of oxygen in the oxide ÷ molar mass of oxygen.

n(O) = m(O) ÷ M(O) amount of oxygen

n(O) = 22.24g ÷ 16 g/mol,

amount of oxygen i.e. n(O) = 1.39 mol

Mass of metal in the oxide, i.e., m(M) = 100 g - 22.24 g.

Mass of metal in the oxide i.e., m(M) = 77.76g

Now we to find the molar mass of metal oxide,

Molar mass of the metal :

= mass of metal in the oxide ÷ amount of oxygen(M)

= m(M) ÷ n(M). M(M)

= 77.76 g ÷ 1.39 mol.

Molar mass of the metal will be 5.94 g/mol.

Therefore, The identity of the metal is lead (Pb).

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.
