In order for plants to entice pollinators, they must first offer their favorite foods: nectar and protein. Since most pollinators fly, the colors of a flower must attract them; therefore, the brighter the flower, the more likely it will be visited. ... For instance, bees are attracted to bright blue and violet colors.

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?
Answers
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.

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:
5) donating H to a solution when they have been depleted and accepting H when they are in excess.
Explanation:
A buffer solution is a solution that undergoes a negligible change in pH in addition of moderate quantities of acid or alkali. In other words, a buffer solution is one that resists a change in pH on addition or dilution of small amounts of acids or alkalis.
So, from the given question:
Buffers are substances that help resist shifts in pH by donating H to a solution when they have been depleted and accepting H when they are in excess.

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.

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
Answers
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.
