Answer:

A population or group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring but do not produce viable, fertile offspring with members of other such groups

Explanation:

I used my bio textbook for this but basically only organisms in a group is a population and they can't produce offspring that survive or reproduce unless they are in the same population or populations. Think of like how a liger is a cross of a tiger and a lion and can't reproduce because its not fertile and its from two different species but a lion and a lion can produce a living offspring that can reproduce.

At a fixed volume, a four-fold increase in the temperature of a gas will lead to _______ in pressure.

timofeeve [1]

Answer:

D) a four-fold increase

Explanation:

According to Gay-Lussac's law, which states that the pressure of a given amount of gas is directly proportional to the temperature at a constant volume, the pressure increases with an increase in temperature.

According to this question, at a fixed volume, a four-fold increase in the temperature of a gas will lead to a four-fold increase in the pressure as well.

Write a balanced net ionic equation showing only the particles involved in the reaction and balancing the charges.Pb(s) AgNO3aq)

Alexus [3.1K]

Answer:

Pb(s) + 2Ag+(aq) → 2Ag(s) + Pb2+(aq)

Explanation:

Step 1: The unbalanced equation

Pb(s) + AgNO3aq) → Ag(s) + Pb(NO3)2(aq)

Step 2: Balancing the equation

Pb(s) + AgNO3aq) → Ag(s) + Pb(NO3)2(aq)

On the right side we have 2x NO3, on the left side we have 1x NO3.

To balance the amount of NO3 on both sides, we have to multiply AgNO3 (on the left side) by 2.

Pb(s) + 2AgNO3aq) → Ag(s) + Pb(NO3)2(aq)

On the left side we have 2x Ag, on the right side we have 1x Ag.

To balance the amount of Ag on both sides, we have to multiply Ag (on the right side) by 2. Now the equation is balanced.

Pb(s) + 2AgNO3(aq) → 2Ag(s) + Pb(NO3)2(aq)

The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will look like this

Pb(s) + 2Ag+(aq) → 2Ag(s) + Pb2+
