What are two ways in which the safe house of lean might influence a product owner?

Answer:

a) The wrong denominator for the equivalent fraction of kilograms to grams

b) The use of the scale factor of length rather than the scale factor of volume for the equivalent fraction of cubic centimeters to cubic meters

c) The arrival at the correct 1000 kg/m³ rather than 0.1 g/m³ based on the expression on the left of the equation

The density of water = 1 g/cm³

The given equation is presented as follows;

1 g/cm³ × 1 kg/(1000 kg) × 100 cm³/(1 m³) = 1000 kg/m³

The error in the conversion method are;

a) The conversion, 1 kg/(1,000 kg) has an error, the correct conversion is (1 kg)/1,000 g)

b) The volume conversion error, 100 cm³/(1 m³), the correct volume conversion is (100 cm)³/(1 m³) = 1,000,000 cm³/(1 m³)

c) The right of the equal to sign error; using the left side expression only, the (wrong) answer is 0.1 g/m³

The correct equation is presented as follows;

1 g/cm³ × 1 kg/(1000 g) × 1,000,000 cm³/(1 m³) = 1000 kg/m³

1.5 moles of [tex]O_{2}[/tex] gas

Reaction of Al with [tex]O_{2}[/tex] to form [tex]Al_{2} O_{3}[/tex] is given below...

2 Al + 1.5 [tex]O_{2}[/tex] → [tex]Al_{2} O_{3}[/tex]

Here, 2 moles of Aluminum reacts with 1.5 moles of [tex]O_{2}[/tex]

atomic weight of aluminum = 27 g / mole

so, 1 mole of aluminum contains 27 g

then how many moles are there if it has 54 g in it.

moles of aluminum in 54 g = 54/27 = 2 moles

As per the equation mentioned above,

2 moles of aluminum reacts with 1.5 moles of [tex]O_{2}[/tex].

∴1.5 moles of oxygen gas (02) are needed to completely react with 54.0 g of aluminum.

V₂ = 167 cm₃

Explanation:

Because you are only dealing with volume and temperature, you can use Charles' Law to find the missing value. This formula looks like this:

V₁ / T₁ = V₂ / T₂

In this formula, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature. You have been given values for all of the variables except for final volume. Therefore, by plugging these values into the formula, you can simplify to find your answer.

V₁ = 100 cm³             T₁ = 150 °C

V₂ = ?                        T₂ = 250 °C

V₁ / T₁ = V₂ / T₂                                          <---- Charles' Law formula

(100 cm³) / (150 °C) = V₂ / (250 °C)           <---- Insert values

(0.667) = V₂ / (250 °C)                               <---- Simplify left side

(0.667) x (250 °C) = V₂                              <---- Rearrange

167 = V₂                                                     <---- Simplify left side

The balanced equation will be [tex]CH_4 + 2O_2 --- > CO_2 + 2H_2O[/tex]

The balanced equation of the reaction would be as follows:

[tex]CH_4 + 2O_2 --- > CO_2 + 2H_2O[/tex]

The mole ratio of methane to carbon dioxide is 1:1.

10 grams of methane will give 10/16 = 0.625 moles

0.625 moles of carbon dioxide would give 0.625 x 44.01 = 27.506 grams.

Thus, 10 grams of methane will produce approximately 27 grams of carbon dioxide stoichiometrically.

The reaction obeys the law of conservation of mass because the atoms of all the elements before and after the reaction are balanced.

Answer:

D

Explanation:

The liquid loses energy while being cooled. It therefore changes to a solid when the liquid is cooled from a temperature above 80°C to 80°C

A substance has a melting point of 80 °C.  It will also change from a liquid to a solid at 80 °C while the liquid loses energy and the correct option is option D.

At the substance's melting point of 80 °C, it undergoes a phase transition from a liquid to a solid. During this transition, the substance loses energy to the surroundings as it releases heat to form a solid structure. The process is called solidification or freezing.

As the substance cools down from a higher temperature to 80 °C, its molecules lose kinetic energy, and they arrange themselves into a more ordered and stable lattice, resulting in the formation of a solid. This release of energy is why the liquid loses energy during the transition. Once the substance reaches 80 °C, it remains at this temperature until the entire amount has solidified.

Thus, the ideal selection is option D.

Answer:

C.) They have fewer electrons than protons

Explanation:

Charges on ions are determined by the ratio of electrons to protons. Neutral elements have the same number of protons and electrons. Remember: protons have a positive charge and electrons have a negative charge. However, based on the amount of electrons these elements have, some are more or less willing to give up their electrons to participate in ionic bonding. Potassium usually gives up 1 electron because this satisfies the octet rule. By removing this electron, the element has more protons than electrons, giving it an overall +1 charge.

Yes, an electron cause an electromagnetic wave to vibrate.

One of the waves is propagated by simultaneous periodic variations of electric and magnetic field intensity and that includes radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Electromagnetic waves are produced when something vibrates—an electric charge that moves back and forth.

When an electric charge vibrates, the electric field around it changes. Because the electric charge is in motion, it also has a magnetic field around it.

This magnetic field also changes as the charge vibrates.

Therefore, an electron causes an electromagnetic wave to vibrate.

The molarity of the HCl acid will be 0.001 M.

A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H⁺ ions and OH⁻ ions to generate water.

This is the neutralization of a strong acid (HCl) and a strong base (NaOH), which is ruled by this equation :

HCl (aq) + NaOH (aq) → NaCl (aq) + H₂O (l)

Mole Ratio : 1 mol HCl : 1 mol NaOH

Formula used ;

Molarity  = number of moles  / Volume  (in liters)

Solve for n ;

n = M × V

Substitute values and compute ;

n = 0.40 M × 0.025 liter = 0.01 moles NaOH.

As the molar ratio is NaOH : HCl

Therefore, there will be same number mole for the HCl

Now, Molarity of HCl Solution ;

Molarity = n / volume

Molarity = 0.01 / 10

             =  0.001 M HCl

Hence, The molarity of the HCl acid will be 0.001 M.

When conditions for a gas change under constant pressure (and the number of molecules doesn't change), it follows Charles' Law:

[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]  where the temperatures must be measured in Kelvin

To convert from Celsius to Kelvin, add 273, or use the equation:  [tex]T_C+273=T_K[/tex]

For this problem, one must also recall that standard temperature is 0°C (or 273K).

So, [tex]T_1 = 273[K][/tex], and [tex]T_2 = (49.4+273)[K]=322.4[K][/tex].

[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

24 molecules of H2O are needed by the plant to produce 4 molecules of sugar.

The process by which plants convert carbon dioxide, water, and sunlight into oxygen and sugar-based energy is known as photosynthesis.

                   6CO2 + 6H2O + Sunlight → C6H12O6 + 6O2

The following three significant activities are involved in photosynthesis:

1. Chlorophyll absorbs light energy.

2. Water molecules are divided into hydrogen and oxygen and light energy is converted to chemical energy.

3. Carbon dioxide is converted to sugars.

Therefore, a plant needs four molecules of H2O and four molecules of CO2 to make one molecule of glucose or sugar, hence a plant needs 24 molecules of H2O and 24 molecules of CO2 to make four molecules of sugar.

Answer:

+1

Explanation:

The oxidation state of Hg in Hg2Cl2 is +1. It has +1 state. 0=2Hg +2 (-1) Hg=+1. Mercury chloride (HgCl2) is considered as the dominant form of mercury in coal combustion flue gas. The oxidation state of an atom is the charge of this atom after ionic approximation of its heteronuclear bonds. The oxidation number is synonymous with the oxidation state. Determining oxidation numbers from the Lewis structure (Figure 1a) is even easier than deducing it from the molecular formula (Figure 1b). The oxidation number of each atom can be calculated by subtracting the sum of lone pairs and electrons it gains from bonds from the number of valence electrons. Bonds between atoms of the same element (homonuclear bonds) are always divided equally. When dealing with organic compounds and formulas with multiple atoms of the same element, it's easier to work with molecular formulas and average oxidation numbers (Figure 1d). Organic compounds can be written in such a way that anything that doesn't change before the first C-C bond is replaced with the abbreviation R (Figure 1c). Unlike radicals in organic molecules, R cannot be hydrogen. Since the electrons between two carbon atoms are evenly spread, the R group does not change the oxidation number of the carbon atom it's attached to.
