Suppose you have 2.50 L of a substance with a density of 8.00 g/mL and you want to determine the mass of the substance. The calculation can be broken down into three steps. First, convert the volume from liters to milliliters. Then, determine the mass of the sample in grams. Finally, convert the mass from grams to kilograms. Show the unit analysis by placing the correct components into the unit‑factor slots. The question marks (?) represent the answer to the previous step.

Answer:

Mud

Explanation:

Mud is a solid mass and water is a liquid mass.  The water takes some attributes of the solid and mixes the two forms of matter.  both masses create mud  it's basic alchemy

Answer:

The transfer was essential to understand the mutation and the possibility of new, more resistant strains in microorganisms.

Explanation:

the transfer of microorganisms is based on the transfer of genetic data through conductive pathways that penetrate the membranes, called pili or genetic bridges.

These mutated genes with higher resistance are transmitted and resistance is generated in entire populations and even species.

Answer:

They are resonance contributors

Explanation:

Resonance structures are structures that differ only in the distribution or placement of electrons.

Considering the two structures, we can easily see that the two species have the same total number of bonds and electrons differing only in the distribution of these electrons.

Hence, they are resonance contributors.

Answer: Rate = 0.14 kg/s

Explanation: The Haber reaction is demonstrated below in the balanced equation

[tex]N_{2}+3H_{2}[/tex] → [tex]2NH_{3}[/tex]

To determine the rate of ammonia production, we need to determine the amount of nitrogen gas is being consumed.

As it is a gas, we can find moles by using Ideal Gas Law, whose formula is

PV = nRT

P is pressure

V is volume

n is moles

R is universal gas constant

T is temperature in Kelvin (K)

For the nitrogen gas, temperature will be

T = 273 + 17.2

T = 290.2 K

Solving for moles:

[tex]n=\frac{PV}{RT}[/tex]

[tex]n=\frac{0.88(112)}{0.082(290.2)}[/tex]

n = 4.14 moles

In the Haber reaction, it is consumed 4.14 moles per second of nitrogen gas.

From the balanced equation, we know 1 mol of nitrogen gas produces 2 moles of ammonia, so

[tex]n_{NH_{3}}[/tex] = 2(4.14)

[tex]n_{NH_{3}}[/tex] = 8.48 moles

Number of moles (n) is mass in grams divided by molar mass of the compound:

[tex]n=\frac{m}{M}[/tex]

Molar mass of ammonia is M = 17.031 u, so mass produced is

m = n.M

m = 8.48(17.031)

m = 144.42 g

In kilograms, m = 0.14 kg

When consuming N₂ at a rate of 4.14 moles/s, it will be produced ammonia at a rate of 0.14 kg/s

Viewed simply, electrons are arranged in shells around an atom's nucleus. Electrons closest to the nucleus will have the lowest energy. Electrons further away from the nucleus will have higher energy. ... In a more realistic model, electrons move in atomic orbitals, or subshells.

By definition:

The Electronic Configuration of the elements is the arrangement of all electrons of an element in energy levels and sub-levels (orbitals).  

There are 7 energy levels, numbered from 1 to 7, and in which electrons are distributed, logically in order according to their energy level. Electrons with less energy will be spinning at level 1.

Each level is divided into sub-levels. These sub-levels into which each level is divided can be up to 4. These 4 sub-levels are called: s, p, d, f.

In the sub-level s there can only be a maximum of 2 electrons, in sub-level p there can be a maximum of 6 electrons, in the sub-level d 10 electrons and finally in the sub-level f there can be a maximum of 14 electrons.

Aufbau's principle is a principle of atomic physics, which explains how electrons are accommodated in their orbits around the nucleus of the atom. This principle states that the filling of these orbitals occurs in increasing order of energy, that is, from the orbitals of lower energy to those of higher energy.

The simplest of the sub-levels is 1s. If you fill the 1s you can start filling the 2s. After the 2s sub-level is satisfied, the 2p can begin to fill and so on. The order is:  

1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d¹⁰6p⁶7s²5f¹⁴6d¹⁰7p⁶

In this way, taking into account the atomic number Z of the element (which represents the number of protons of the element, and in a neutral atom it also indicates the number of electrons), the electrons that it has in the orbitals will be placed following the previously established.

For example, for hydrogen, whose atomic number is Z = 1, its electronic configuration would be: 1s¹.

Remember that the number 1 that precedes the representative letter of the orbital indicates the level of energy where the electron is located, the letter s indicates the type of orbital where the electron is located, and the exponent 1 indicates the number of electrons that are located in said orbital.

Answer:

2.35

Explanation:

A 1.00-L flask was filled with 2.00 moles of gaseous SO₂ and 2.00 moles of gaseous NO₂ and heated. After equilibrium was reached, it was found that 1.21 moles of gaseous NO was present. Assume that the reaction

SO₂ + NO₂ ⇌ SO₃ + NO

occurs under these conditions. Calculate the value of the equilibrium constant, K, for this reaction.

Step 1: Calculate the molar concentrations

Since the reaction takes place in a 1.00 L flask, the molar concentrations are:

[SO₂]i = 2.00 M

[NO₂]i = 2.00 M

[NO]eq = 1.21 M

Step 2: Make an ICE chart

        SO₂ + NO₂ ⇌ SO₃ + NO

I       2.00   2.00       0        0

C        -x       -x         +x       +x

E    2.00-x  2.00-x    x         x

Step 3: Calculate the concentrations at equilibrium

The concentration of NO at equilibrium is 1.21 M. Then, x = 1.21.

[SO₂]eq = 2.00-1.21 = 0.79 M

[NO₂]eq = 2.00-1.21 = 0.79 M

[SO₃]eq = x = 1.21 M

[NO]eq = x = 1.21 M

Step 4: Calculate the value of the equilibrium constant, K, for this reaction

K = [SO₃] × [NO]/[SO₂] × [NO₂]

K = 1.21²/0.79² = 2.35

J. the growth of trees

Explanation:

The growth of trees would be greatly impaired if the energy from the sun were stopped.

Plants generally use the energy from the sun to obtain their nourishment. This same process makes food available in the ecosystem.

Answer:

C) 2, 4.

Explanation:

Hello!

In this case, since the sulfur atom has six electrons at its outer shell, it suggests it needs to gain two electrons in order to attain a complete octet, that is why it has 2 paired electrons.

Moreover, since two electrons are paired, then 4 electrons will remain unpaired; therefore the answer would be C) 2, 4.

Answer:

antimony

Explanation:

The representation of the electrons in the shell is called electronic configuration.

The correct answer is antimony

The shell is as follows:-

These are the shells in which electrons are filled.

The total number of electrons is 2+2+6+2+6+2+10+6+2+7= 45

After calculating the electrons, the total number of electrons is 45 which is the atomic number of antimony.

Hence, antimony is the correct option.

Explanation:

Thermal energy is the energy transfer of heat which is created while doing physical activity.

Answer:

189.71 secs

Explanation:

We know that decomposition is a first order reaction;

So;

ln[A] = ln[A]o - kt

But;

[A]o = 1.00 M

[A] = 0.250 M

t =135 s

Hence;

ln[A] -  ln[A]o = kt

k = ln[A] -  ln[A]o/t

k = ln(1) - ln(0.250)/135

k =0 - (-1.386)/135

k = 1.386/135

k= 0.01

So time taken now will be;

ln[A] -  ln[A]o = kt

t = ln[A] -  ln[A]o/k

t = ln (3) - ln(0.450)/0.01

t = 1.0986 - (-0.7985)/0.01

t = 1.0986 + 0.7985/0.01

t = 189.71 secs

yes; and because of how roughly they are played.

Explanation:

Answer:

A is 1000, B is 1 and C is 5,400.

Explanation:

Hello!

In this case, since we are dealing with an unit conversion from liters to milliliters, we need to keep in mind that the proper conversion factor is:

[tex]\frac{1000mL}{1L}[/tex]

Thus, the set up turns out:

[tex]5.4L*\frac{1000mL}{1L} =5,400mL[/tex]

Thus, A is 1000, B is 1 and C is 5,400.
