Answer:
The stack would be 5.002 × 10⁷ inches high.
Explanation:
1 mole of ice cubes contains 6.022 × 10²³ cubes,
1 ice cube has a volume of 1 in³
This translates to a total volume of 6.022 × 10²³ in³
If we call the height of the stack of ice cubes we're about to produce H
The volume of ice cubes we have will take up a volume of [(3 × 10⁶)mi² × H]
Hence, we convert this area of land to in²
3 × 10⁶ mi² = 1.204 × 10¹⁶ in²
Therefore
6.022 × 10²³ = 1.204 × 10¹⁶ × H
H = (6.022 × 10²³)/(1.204 × 10¹⁶) = 5.002 × 10⁷ inches.
Oxygen (6O2) and Glucose (C6H12O6)

Functional groups are the set of atoms in a compound that's responsible for the chemical properties of the compound.
the functional groups for the given compounds are as follows
methanoic acid = carboxylic group
chloroethane = haloalkane
propanone = ketone
option A is incorrect as only one of the given compounds is a carboxylic acid, others have other functional groups
option C is incorrect as they have three different functional groups as stated above
option B is incorrect as its not a homologous series. Homologous series are a set of compounds with same functional group that differs by a CH₂ group. since the functional groups are different it does not belong to a homologous series as well .
correct option is D. none of these
as none of the other options are correct
Answer:
The biology of the ecosystem is always studied from the composition of organisms, population and community.
Explanation:
- In an ecosystem, various processes are sustained and these processes regulate the environment, as the biotic communities in the ecosystem make up the biosphere.
- Various life processes, their interaction, movement, and successional development ecosystem and the distribution of organisms are the focus of biological organization levels of ecology.
- First comes the organism ecology level as the researchers study their adaptations for the structure and physiographic behavior. Second is the population ecology level with a group of interbreeding organisms next level is of Community ecology and ecosystem ecology as they study the different species within the area using a three-dimensional model.
- After these the ecosystem ecology that is an extension of all the levels in the ecosystem. The natural environment can provide all the needed nutrients and life-supporting factors.
The mass percent of each compound is
- (NaBr*2H2O)=85.71 percent
- (MgBr2*6H2O)=14.29 percent
<h3>The mass percent equation is as follows.</h3>
The formula mass percent is the most effective way to express mass percent: mass percent = (mass of chemical x total mass of compound) times 100. Add 100 to the top value to get the value expressed as a percentage.
<h3>What percentage by mass does a solution have?</h3>
By multiply the grams of solute per gram of solution by 100, it is possible to get the mass percent of a solution.
The molar mass of each element and the mass of each element contained in a mole of the compound are both solved for in the Mass Percent formula.
