Answer:

We deduce that the correct option is option c: critical period

Explanation:

Hello!

Let's solve this!

The imprint is the learning that occurs in early ages, the example of the duckling is used, which follows anyone in early periods.

This is called the critical period.

We deduce that the correct option is option c: critical period

The equation below shows lithium reacting with nitrogen to produce lithium nitride. 6Li + N2 2Li3N If 12 mol of lithium were rea
Andreyy89

Answer:

4 mol  of lithium nitride would be produced

Explanation:

6Li + N2  → 2Li3N

This equation means that 6 mol of lithium are reacted with 1 mol of nitrogen to make, 2 mol of lithium nitride.

So this is the rule of three to find out, how many moles of lithium nitride are been made, from 12 mol of Li.

6 Li _____ 2 Li3N

12 Li ________ (12. 2) / 6 = 4 moles

To what temperature must a sample of nitrogen at 27°C and 0.625 atm be taken so that it’s pressure becomes 1.125 atm at constant
Karo-lina-s [1.5K]

Answer:

The sample of nitrogen must be taken to 267 ^{0}\textrm{C}.

Explanation:

Let's assume nitrogen gas behaves ideally.

Here amount of nitrogen gas in both states remain constant.

So, in accordance with combined gas law for a given amount of an ideal gas in two different states:            \frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}

where P_{1} and P_{2} are initial and final pressure respectively. V_{1} and V_{2} are initial and final volume respectively. T_{1} and T_{2} are initial and final temperature (in kelvin scale) respectively.

Here V_{1}=V_{2} , P_{1}=0.625atm , T_{1}=(273+27)K=300K and P_{2}=1.125atm

So T_{2}=\frac{P_{2}T_{1}}{P_{1}}=\frac{(1.125atm)\times (300K)}{(0.625atm)}=540K

540 K = (540-273) ^{0}\textrm{C} = 267 ^{0}\textrm{C}

So the sample of nitrogen must be taken to 267 ^{0}\textrm{C}.
