Explanation: Synthesis Reaction is when you get same thing on the other side even if its not in the same order after you add the components.

Two molecules having different sizes but the same functional groups will take part in chemical reactions. Functional groups are used in the field of organic chemistry. Here the given molecule has ketone functional group. The correct option is D.

The substituent atoms or groups of atoms which are attached to specific molecules are defined as the functional groups. These moieties are responsible for the chemical reactions. The same functional group will experience comparable reactions regardless of the chemical in which it is present.

A ketone is a functional group which consists of a carbonyl carbon bound to an oxygen atom by a double bond and two alkyl or aryl groups. Ketones are usually represented as RCOR, where two R's can be any alkyl or aryl group. Their general formula is CₙH₂ₙO.

Lower ketones are soluble in water because they consist of the polar carbonyl group.

Thus the correct option is D.

Answer: Clouds need two things to form: cool air and particles on which water vapor can condense. Clouds form as air cools. Cold air cannot hold as much water vapor, so the water vapor condenses. Water vapor condenses on small particles in the atmosphere, such as smoke, salt, and dust. As a result, clouds form.

Explanation:

Manganese metal is produced from the manganese(III) oxide, Mn2O3, which is found in manganite, a manganese ore. The manganese is reduced from its +3 oxidation state in Mn2O3 to the zero oxidation state of the uncharged metal by reacting the Mn2O3 with a reducing agent such as aluminum or carbon. How many pounds of manganese are in 1.261 tons of Mn2O3? (1 ton = 2000 pounds)

About 40 different substances called organophosphorus compounds are registered in the United States as insecticides. They are considered less damaging to the environment than some other insecticides because they breakdown relatively rapidly in the environment. The first of these organophosphorus insecticides to be produced was tetraethyl pyrophosphate, TEPP, which is 33.11% carbon, 6.95% hydrogen, 38.59% oxygen, and 21.35% phosphorus. It has a molecular mass of 290.190.

A quantity can be converted from one unit of measurement to another while maintaining its value. There are 2522 pounds of manganese in 1.261 tons of [tex]\rm Mn_2O_3[/tex].

It is a fundamental idea that is applied in many different disciplines such as science, engineering, math and daily life. To complete a conversion, it is necessary to know the conversion factor – the numerical relationship between the two units of measurement. With the help of this factor, you are able to convert units while keeping the value constant.

To convert tons to pounds we need to know that 1 ton is equal to 2000 pounds.

Given that you have 1.261 tons of [tex]\rm Mn_2O_3[/tex], we can calculate the number of pounds as follows:

Number of pounds = 1.261 tons * 2000 pounds/ton

Number of pounds = 2522 pounds

Therefore, there are 2522 pounds of manganese in 1.261 tons of [tex]\rm Mn_2O_3[/tex].

The Gibbs Free Energy at 298 K, AH = 46 kJ/mol and sº = 0.097 kJ/(K-mol) is 28.906 kJ/mol

It serves as the single master variable that determines whether a given chemical change is thermodynamically possible.

Thus if the free energy of the reactants is greater than that of the products, the entropy of the world will increase when the reaction takes place as written, and so the reaction will tend to take place spontaneously.

Conversely, if the free energy of the products exceeds that of the reactants, then the reaction will not take place in the direction written, but it will tend to proceed in the reverse direction.

At 298 K,

AH = 46 kJ/mol

and sº = 0.097 kJ/(K-mol).

ΔG=ΔH−T⋅ΔS

ΔG = 46 - 298 * 0.097

ΔG = 46 - 28.906

ΔG = 28.906 kJ/mol

The Gibbs Free Energy at 298 K, AH = 46 kJ/mol and sº = 0.097 kJ/(K-mol) is 28.906 kJ/mol

Answer:

34.5J

Explanation:

Amount of Heat(Q) = mc∆T

where m (mass of aluminum) = 5.50g

c (specific heat capacity of aluminum) = 0.897J/g°C and ∆T = 95.0°C - 25.0°C = 70.0°C

Q = 5.50x 0.897x 70.0

= 34.5354J = 34.5J

The amount of heat absorbed when 5.50 g of aluminum is heated from 25.0°C to 95.0°C is 34.5 J.

Heat is defined as a form of the energy transmitted from one body to another as a result of a temperature difference.

It can also be defined as the potential energy stored in the bonds that hold the object's particles together.

Heat absorption is defined as absorption of heat without increasing the temperature at the certain point.

Amount of heat = mcΔT

Where m = 5.50g

           c = 0.897 J/g °C

           ΔT =  95.0°C - 25.0°C

                 = 70.0°C

So, amount of heat = 5.50 x 0.897 x 70.0

                                = 34.5354 J = 34.5 J

Thus, the amount of heat absorbed when 5.50 g of aluminum is heated from 25.0°C to 95.0°C is 34.5 J.
