Consolidating the european aerospace industry was a strategic decision to compete against boeing because boeing had a ________ advantage.

Answer:

increase the rate of reaction

Answer:

yes the answer is c

Explanation:

The oxidation state of transition metal in the product Potassium hexacyanomanganate(II) reacts with K metal to form K₆[Mn(CN)₆] is +2.

K4 [ Mn(CN)6 ] is a coordination compound. The potassium ion is the cation and the complex ion is the anion. As there are 4 K+ binding with a complex ion, the charge on the complex ion must be - 4. As each ligand carries –1 charge, the oxidation number of Mn must be +2.

oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.

Taking into account the definition of calorimetry, the temperature change of A will be one sixth of the temperature change of B.

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

So, the equation that allows to calculate heat exchanges is:

Q = c× m× ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case, for object A:

QA = cA× mA× (ΔT)A

and for object B:

QB = cB× mB× (ΔT)B

You know:

Object A has double the specific heat of object B. ⇒ cA= 2× cB

Object A has triple the mass of object B. ⇒ mA= 3× mB

If the same amount of heat is applied to both objects ⇒ QA= QB

Then:

cA× mA× (ΔT)A= QB = cB× mB× (ΔT)B

2× cB × 3× mB× (ΔT)A=  cB× mB× (ΔT)B

Solving:

6× cB × mB× (ΔT)A= cB× mB× (ΔT)B

(ΔT)A= (cB× mB× (ΔT)B) ÷ (6× cB × mB)

(ΔT)A=\(\frac{1}{6}\) (ΔT)B

Finally, the temperature change of A will be one sixth of the temperature change of B.

The percentage error of a result is the ratio of the difference between true value and observed value to the true value multiplied by 100. The percentage error in surface tension here is 0.95%.

Every experimental value may be associated with some errors. The error represents the deviation of the calculated value from the expected or true value.

The percent error is 100 multiplied with the relative error.

percent error = true value - observed value/ true value × 100

Given that the true value of surface tension of water = 71.97 dyn/cm

Experimental / observed value = 71.28 dyn/cm

then percent error = 71.97 - 71.28 / 71.97  × 100 = 0.95 %.

Therefore, the percent error of tensiometer is 0.95%.

To produce one molecule of glucose, 6 molecules of carbon dioxide (\(CO_{2}\)), 18 molecules of adenosine triphosphate (ATP), and 12 molecules of nicotinamide adenine dinucleotide phosphate (NADPH) are required.

Glucose, a six-carbon sugar, is synthesized through the process of photosynthesis in plants. It involves the Calvin cycle, which incorporates carbon dioxide, ATP, and NADPH to produce glucose. For each molecule of glucose formed, 6 molecules of carbon dioxide are required.

The energy needed for glucose synthesis is provided by ATP, which is an energy-rich molecule. In the Calvin cycle, the synthesis of one glucose molecule requires 18 molecules of ATP.

NADPH, a coenzyme involved in energy transfer reactions, is required for the reduction of carbon dioxide during the Calvin cycle. In the process, 12 molecules of NADPH are utilized to produce one molecule of glucose. These components play crucial roles in capturing and storing energy, as well as providing carbon atoms for the formation of glucose, which serves as a vital energy source for organisms.

Pentane is a nonpolar molecule composed of only carbon and hydrogen atoms. It lacks any polar functional groups or charged regions that can effectively interact with ions. Li+ ions are positively charged and tend to interact more strongly with molecules that have polar functional groups or lone pairs of electrons. In contrast, pentane's nonpolar nature and symmetrical structure minimize its ability to form significant interactions with ions. It lacks any specific sites or charges that can attract or interact with the Li+ ion, resulting in the least interaction.

Explanation:

You dip a strip of damp pH paper into the test tube and get no reaction. Hence, option B is correct.

Electrolysis is a technique that uses a direct electric current to drive an otherwise non-spontaneous chemical reaction.

The true facts about electrolysis are as explained;

Electrolysis is described by two half-reactions. These half-reactions are the oxidation half-reaction and reduction half-reaction.

Electrolysis results in commercially valuable products. This is evident in electroplating when valuable metals are used to plate one's of less value.

Electrolysis involves the transfer of electrons. Each half reaction is characterized by the loss or gain of electrons.

Oxidation results in the loss of electrons.

The false statements are;

Electrolysis requires an acid to be present. This is false because the presence of an acid is not mandatory during electrolysis.

Electrolysis is not an industrial process. The statement above is false because industrial purification of many metals requires electrolysis.

Bond order is the number of electron bonding pairs that exist between two atoms. A quadruple bond is a form of chemical relationship that involves eight electrons between two atoms. This bond is a variation on the more common double and triple bonds.

The number of bonds that an atom may make is frequently predicted by the number of electrons required to achieve an octet (eight valence electrons); this is notably true .

The property that cannot be used to determine whether the two powders are the same substance is (d) dissolves in water.

The reason is that the ability to dissolve in water is not a unique property that can be used to identify a specific substance. Many different substances can dissolve in water, and the fact that both powders can dissolve in water does not necessarily mean they are the same substance.

On the other hand, properties such as mass, density, and the ability to burn in air can provide more specific information about the nature of the substance. Mass is a fundamental property that can be measured accurately, and if the two powders have the same mass, it suggests they may be the same substance. Density is a derived property that can also be measured and compared, providing information about the compactness of the material. The ability to burn in air indicates a chemical reactivity that can be used to distinguish between different substances.

Therefore, while properties like mass, density, and burning in air can provide valuable information for identifying substances, the property of dissolving in water alone is not sufficient to determine whether the two powders are the same substance.
