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
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.

Help plzzzzz it's due today ----- Would Shining light on the reaction increase or decrease the reaction rate
Answer:
increase
Explanation:
Reactions that are initiated by light are called photochemical reactions. The brighter the light, the faster the reaction.
Answer: An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).

how do I find the slope of this graph? Is it even possible?
Answer:
Not exactly But you can take the slope of the curved portion and the slope of the flatline.
It wont do you much good since your working for absorbance but if you ever see something like a temperature change you can use the slope(s) to find freezing points/melting
Explanation:
If you need to submit a slope you could use a best fit which is just point to point or you could break it up like i mentioned

How many moles are in 74.8 grams of NaCl?
Answer:
1.28 mol NaCl
Explanation:
Find the mass of NaCl by adding the two elements atomic mass
Na: 22.99
Cl: 35.45
22.99+35.45=58.44 g
Now convert to moles
74.8 g / 58.44 g = 1.27994524298 mol
C5H12 + O2 = CO2 + H2O
If 84.3 grams of C5H12 react according to the above equation and the % yield is 94% find the actual yield of grams of carbon dioxide
Answer: 241.6 grams of CO2
Explanation: you take 84.3 grams C5H12 and divide it by 72.15 grams of C5H12(which is the molar mass) you take that answer and calculate the mols of CO2 by multiplying the 1.168 you got before and multiply it by 5. You take the answer you get from that and multiply it by the molar mass of CO2 and get the theoretical yield and then you just plug it in. 94= (x/257.02)x100 and solve to find x which is the actual yield.

1.I make my cup of coffee in the morning by pouring boiling water over ground-up coffee beans held in a special piece of paper and by collecting the brown liquid that comes through. Which techniques of the five described in the background section is/are used in the preparation of the cup of coffee
Answer:
Filtration
Explanation:
Filtration is a physical separation technique that is used to separate solids from liquids or gases. The process involves the use of a filter which allows just the liquid to pass through.
In this case, the coffee beans is the solid and the boiling water is the liquid. The special piece of paper is the medium (filter) through which the coffee is collected.
The coffee coming through the special piece of paper (filter) is called a filtrate.
Filtration is used in the preparation of the cup of coffee.

help me with this
Explanation:
Explain the difference between endothermic and exothermic processes. Provide an example of each.
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.

Jewelry and tableware are sometimes made of sterling silver. Sterling silver is 92.5% silver (Ag) and 7.5% copper (Cu). If you wanted to make 30 grams of sterling silver for a ring, how many grams of silver and copper would you need to start with?
Amount of sterling silver?
Amount of copper?
total grams of alloys needed?
Answer:
12.33
Explanation:
92.5/7.5= 12.33
30g of the sterling silver ring contains, 27.75 g of silver and 2.25 g of copper.
What is cross multiplication?Cross multiply fractions by multiplying one fraction's denominator by the other fraction's numerator and then comparing the two values. The larger fraction is the one with the higher value.
100g of sterling silver contains 92.5g of silver and 7.5g of copper.percentage of element = amount of the element present in 100 g of materialTherefore,
100g sterling silver = 92.5g silver30g sterling silver = X g silver( cross multiplication),
100 × X = 92.5 × 30
X = 92.5 × 30/ 100
X= 27.75g silver100g sterling silver = 7.5g copper
30g sterling silver= Y g copper
(cross multiply)
100 × Y = 7.5 × 30
Y= 7.5 × 30 / 100
Y= 2.25g copperX (silver)= 27.75 g in 30 g of sterling silverY (copper)= 2.25 g in 30 g of sterling silvertherefore, 30g of sterling silver ring contains, 27.75 g of silver and 2.25 g of copper.

1) How many moles of water does 6.02 x 1023 molecules
represent?
Answer:
1.00 mol
Explanation:
Step 1: Given data
Molecules of water: 6.02 × 10²³ molecules
Step 2: Calculate the number of moles corresponding to 6.02 × 10²³ molecules of water
In order to convert molecules to moles, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.
6.02 × 10²³ molecules × 1 mol/6.02 × 10²³ molecules = 1.00 mol (we keep 3 significant figures)
