What information is presented inside each square of the periodic table?

Use an Internet search engine to find a development in any area of science during the past 10 years, and then answer the followi

erica [24]

Answer:

The development I found was "the creation of a 100% artificial cell"

Explanation:

In 2010 scientists led by the American Craig Venter were able to develop a 100% artificial cell. This was a great scientific advance that can improve many things in our future and guarantee a better quality of life, once it is perfected.

The experiment that allowed this development used a synthetic genome created by a computer equal to the genome of the bacteria Mycoplasma mycoides implanted in a cell of another bacteria (2) that had its entire genome removed, but that until then, had not been genetically modified. Upon receiving the genome of the bacteria Mycoplasma mycoides, bacteria 2 was reinitialized and continued its life cycle in a normal way, managing to replicate and give rise to other bacteria containing the synthetic genome.

The advantage of developing this discovery is that in the future, synthetic genomes can be used to create beneficial microorganisms that can be used in the creation of drugs, vaccines, fuels, biological molecules, among others.

The following properties are either physical or chemical. Which one is different from the rest based on those two categories?

inysia [295]

Mass

Explanation:

Mass is different from the rest based on those two categories.

Physical properties are the properties of matter that are usually determined with our senses like taste, feel, color, odor e.t.c

Chemical properties are the properties that relates to a substance when changes are occurring to it.

These properties are boiling point, magnetism and thermal conductivity among others.

Mass is not a physical nor chemical property. It is classified as an extensive property of substances which varies according to the amount of matter it contains.

Compute the molar enthalpy of combustion of glucose (C6 H12O6 ): C6 H12O6 (s) + 6 O2 (g) → 6 CO2 (g) + 6 H2 O (g) Given that com

lana66690 [7]

Answer:

The molar enthalpy of combustion of glucose is -2819.3 kJ/mol

Explanation:

Step 1: Data given

Mass of glucose = 0.305 grams

Combustion of 0.305 grams causes a raise of 6.30 °C

Calorimeter has a heat capacity of 755 J/°C

Molar mass of glucose = 180.2 g/mol

Step 2: The balanced equation

C6H12O6 (s) + 6O2 (g) → 6CO2 (g) + 6H2O (g)

Step 3:

ΔH = (m * C * ΔT + c(calorimeter) * ΔT)

with m = mass of the solutin = 0.305 grams

with C = heat capacity of water = 4.184 J/g°C

with ΔT = the change in temperature = 6.30 °C

with c(calorimeter) = 755 J/°C

ΔH = 0.305 * 4.184 *6.30 + 755 * 6.30 = 4764.5 J ( negative because it's exothermic)

Step 4: Calculate moles of glucose

Moles glucose = mass glucose / Molar mass glucose

Moles glucose = 0.305 grams / 180.2 g/mol

Moles glucose = 0.00169 moles

Step 5: Calculate molar enthalpy

Molar enthalpy = -4764.5 J / 0.00169 moles

Molar enthalpy = - 2819254.2 J/moles = -2819.3 kJ/moles

The molar enthalpy of combustion of glucose is -2819.3 kJ/mol

Each year, due to growing population and energy demands, the United States faces increasing dependency on conventional fossil fu

laiz [17]

Answer:

A) (i) 4*10^12 Ibs , (ii) 600 * 10^9 Ibs

(iii)

Wind energy is a clean energy : this is because there is no consumption of fossil fuels when using wind energy to generate electricity
Wind energy is a renewable energy : wind is reusable and it is always available for use

B) The use of bricks or stone that can absorb the solar heat easily when the sun rays heat them up and this solar heat absorbed . is a typical example of a passive solar heating system.

C) Advantage : It is mostly cost free

disadvantage : there is no storage mechanism

Explanation:

A) Given that U.S uses roughly 4 million Gigawatt-hours per year in electricity and 50% of the electricity comes from coal

<u>i) Determine how much carbon dioxide is released from burning coal each year </u>

since 50% of electricity comes from coal

The Total energy produced by coal =2*10^12 Kw-h. also

1.0 kilowatt-hour of coal burned releases 2 lbs.

hence the Total amount of Carbon dioxide released from burning coal each year = 2 * 2 * 10^12 = 4 * 10^12 Ibs

<u>ii) Determine the reduction of carbon dioxide entering the atmosphere each year if coal usage could be reduced by 15% by utilizing solar energy</u>

= 15% 0f 4*10^12

reduction of coal usage by 15% = 600 * 10^9 Ibs hence the amount of coal entering the atmosphere is reduced by 600 * 10^9 Ibs

iii) Advantages of using wind energy to generate electricity

Wind energy is a clean energy : this is because there is no consumption of fossil fuels when using wind energy to generate electricity
Wind energy is a renewable energy : wind is reusable and it is always available for use

B) Passive solar heating system

The use of bricks or stone that can absorb the solar heat easily when the sun rays heat them up and this solar heat absorbed . is a typical example of a passive solar heating system.

C) advantage and disadvantage of solar heating system

Advantage : It is mostly cost free

disadvantage : there is no storage mechanism
