Answer:GASEOUS, LOWERING ,EMITTED AS HEAT, DOWN,DO NOT RELEASE,DECREASES,NEGATIVE.

Explanation: Filling the blanks gives

Lattice energy is associated with forming a crystalline lattice of alternating cations and anions from the _GASEOUS___________ ions.

Because the cations are positively charged and the anions are negatively charged, there is a LOWERING of potential- as described by Coulomb's law-when the ions come together to form a lattice energy.That energy is EMITTED AS HEAT when the lattice forms.

As the ionic radii increases as you move DOWN a group, ions cannot get as close to each other and therefore DO NOT RELEASE as much energy when the lattice forms. Thus the lattice energy DECREASES (becomes less) NEGATIVE  as the radius increases.

The above gives the  definition of Lattice  Energy and how it relates to atomic and ion charge.

A sample of neon occupies a volume of 478 mL at STP. What will be the volume of the neon when the pressure is reduced to 93.3 kP
Andre45 [30]

The volume of neon when the pressure is reduced to 93.3 kPa is 519 mL.

Explanation:

The kinetic theory of gases is mostly based on Boyle's law. From the Boyle's law, the pressure experienced by any gas molecules is inversely proportional to volume of the gas molecules. Also this inverse relation is obeyed if and only if the number of moles and temperature of the gas molecules remained constant.

So,P=\frac{1}{V}

So if there is a change in pressure then there will be inverse change in volume. That means if there is decrease in the pressure of gas molecules then there will be increase in the volume and vice versa.

So the Boyle's law is combined as P_{1} V_{1} = P_{2} V_{2}

As here the initial pressure or P_{1} is 1 atm or 101.3 kPa and the initial volume is 478 mL. Similarly, the final pressure is 93.3 kPa and the final volume will be

101.3*10^{3}*478*10^{-3}  = 93.3*10^{3} * V_{2}

V_{2} = 519 mL

So, the volume of neon when the pressure is reduced to 93.3 kPa is 519 mL.

A sunscreen preparation contains 2.50% benzyl salicylate by mass. If a tube contains 4.0 oz
antoniya [11.8K]

About 0.92 kg of benzyl salicylate would be needed in order to manufacture 325 tubes of sunscreen.

A tube contains 4.0 oz of the sunscreen and each one 2.5% benzyl salicylate.

         2.5% of 4.0 oz = 0.1 oz

Thus, each tube would need 0.1 oz of benzyl salicylate.

325 tubes of the sunscreen is needed and each one requires 0.1 oz of benzyl salicylate. Hence, total amount of benzyl salicylate needed would be:

    325 x 0.1 oz = 32.5 oz

From conversion:

16 oz = 1 lb

Hence,

32.5 oz = 32.5/16

                        = 2.03 lb

Also:

2.205 lb = 1 kg

2.03 lb = 2.03/2.205

             = 0.92 kg

"survival of the fittest" best means that an organism is​
Nat2105 [25]

The answer is: Survival of the form that will leave the most copies of itself in successive generations.

"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory.

This is example of natural selection and adaptation.

Genetic variation is important to the population's ability to survive in different situations that affect natural selection.  

The environment is constantly changing and different alleles are favored.
