An artificial reef is intended to affect the ocean ecosystem by — А A removing pollution from the water B В providing shelter for marine organisms causing sediment to erode into deeper waters D preventing people from overfishing along the shore
Answers
Answer:
B
Explanation:
just answered
An artificial reef is intended to affect the ocean ecosystem by providing shelter and habitat for marine organisms causing sediment to erode into deeper waters. Hence, option C is correct.
What is artificial reef ?An artificial reef is a human-made underwater structure, typically constructed with the purpose of enhancing marine biodiversity, providing habitat for marine organisms, and promoting recreational activities like fishing, diving, and snorkeling.
Artificial reefs can be created from a variety of materials, such as concrete, metal, tires, and sunken ships. The reef structure can also increase the overall biodiversity of an area by creating a new habitat for species that may not have been present before.
Additionally, the presence of an artificial reef can help to reduce pressure on natural reefs by providing an alternative location for fishing and other activities. However, artificial reefs are not typically used as a means of removing pollution from the water or preventing erosion.
Therefore, option C is correct.

What is the molecular polarity of calcium hydroxide
Answers
Answer:Calcium hydroxide is a polar compound. 2. Carbonates are insoluble in water unless it is combined with NH4+ or any group 1A ion. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed, or slaked with water.Ca(OH)2 is an ionic compound, in which Ca is the cation and OH is the anion. Ca (calcium) has a charge of 2+, since it is in group 2 on the periodic table.

Which one of the following ionic solids would have the largest lattice energy?
CaBr2
CsI
CaCl2
NaCl
NaF
Answers
Answer:
CaCl2
Explanation:
The ionic solid CaCl₂ would have the largest lattice energy. Therefore, option (c) is correct.
What is the lattice energy?Lattice energy is the heat of formation when one mole of crystalline ionic solid is generated from its constituent ions in their gaseous state.
For example, the lattice energy of sodium chloride crystal is the energy change of reaction when Na⁺ and Cl⁻ ions react to produce a NaCl crystal, which is equal to -786 kJ/mol.
The relation between lattice energy and lattice enthalpy at constant pressure is given by:
ΔU (lattice) = ΔH (lattice) - PΔV
Lattice energy is directly proportional to the charge on ions and inversely proportional to the interionic distance between ions.
For NaCl and NaF the charge on the ions is +1 and -1 while the size of the ions is small. So they have less lattice energy.
CsI ionic solid have a larger size of ions Cs⁺ and I⁻. So CsI will have less lattice energy. CsBr₂ has +2 charge on calcium but the size of both ios is larger. So, CsBr₂ will have less lattice energy.
CaCl₂ has + 2 charge on calcium as well as the ionic radius is also samll. Therefore, CaCl₂ would have the largest lattice energy.

Answers
Answer: C
Explanation:
Hot air is a lot less dense for a few reasons. Hot air essentially means the particles have more kinetic energy, and move around a lot more. Cold air is dense because the particles move a lot less, have less energy, and are closer together.
Answer:
A
Explanation:
Since the balloon itself is heavier than air, it must be filled with a large volume of something much lighter—either hot air or a very light gas, such as helium. Because the combined weight of the balloon and the gas is less than the weight of an equal volume of surrounding air, the balloon rises.

Experimental value of acceleration due to gravity is found to be
9.842 m/s2. The accepted value of acceleration due to
gravity is 9.81 m/s2. What is the percent error in calculation?
Answers
Answer:
0.33%
Explanation:
From the question given above, the following data were obtained:
Experimental value = 9.842 m/s²
Accepted value = 9.81 m/s²
Percentage error =?
The percentage error in the calculation can be obtained as follow:
Percentage error = |Experimental – Accepted| / Accepted value × 100
Percentage error = |9.842 – 9.81| / 9.81 × 100
Percentage error = 0.032 / 9.81 × 100
Percentage error = 0.33%
Therefore, the error in the calculation is 0.33%

I have these orgo problems for homework and I have no idea where to even begin. We have to find missing reagents and products based on regioselectivity and stereoselectivity. Any help or explanations would be greatly appreciated!!
Answers
Answer:
Honestly makes no sense sorry :(
Explanation:
I can try though.. There are three types of selectivity possible for any synthesis: (i) Chemoselectivity is deciding which group reacts. (ii) Regioselectivity is where the reaction takes place in that group. (iii) Stereoselectivity is how the group reacts with respect to the stereochemistry of the product.
A stereospecific mechanism specifies the stereochemical outcome of a given reactant, whereas a stereoselective reaction selects products from those made available by the same, non-specific mechanism acting on a given reactant. Of stereoisomeric reactants, each behaves in its own specific way.
I tried to explain it the best I could.

lobal wind patterns have less to do with air temperature than local winds. A True B False
Answers
Answer:
False
Explanation:
Depends mostly on heating of the earths surface being uneven
It is false that global wind patterns have less to do with air temperature than local winds.
What is global wind?Local winds are those that blow over a small area. Local geography, such as proximity to an ocean, has an impact on them.
Monsoons and land and sea breezes are among them. Global winds occur in belts all over the world.
Temperature differences, particularly the difference in heating at the equator and poles, and the Earth's rotation determine the global atmospheric circulation pattern.
By transporting heat and water, winds shape regional climate and influence daily weather.
Global winds are winds that occur in belts that circle the globe. Global winds, like local winds, are caused by uneven heating of the atmosphere.
Because of the Coriolis effect, winds blow diagonally across the surface.
Thus, the given statement is false.

Explain the difference between endothermic and exothermic processes. Provide an example of each.
Answers
These are reactions that transfer energy to the surroundings (ie the energy exits from the reaction, hence the name exothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become hotter. A thermometer is used to detect the temperature increase.
Examples:
Combustion
Neutralisation between acids and alkali
Endothermic reactionsThese are reactions that take in energy from the surroundings (ie energy enters the reaction, which will help you to remember the name endothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become colder. A thermometer is used to detect the temperature decrease.
