<u>Answer:</u>

7

<u>Explanation</u>:

An isotope is an atom that has a different number of neutrons than the standard for that atom.

1)<em>Nitogen</em><em> </em><em>-</em><em>1</em><em>4</em><em> </em><em>has</em><em> </em><em>7</em><em> </em><em>protons</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>nucleus</em><em> </em><em>for</em><em> </em><em>its</em><em> </em><em>an</em><em> </em><em>isotope </em><em>of</em><em> </em><em>nitrogen </em><em>which</em><em> </em><em>has</em><em> </em><em>an</em><em> </em><em>atomic</em><em> </em><em>number</em><em> </em><em>o</em><em>f</em><em> </em><em>7</em><em>.</em>

<em>2</em><em>)</em><em>Now</em><em> </em><em>we</em><em> </em><em>need</em><em> </em><em>to</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>number</em><em> </em><em>of </em><em>neutrons</em><em>.</em><em> </em><em>This</em><em> </em><em>is</em><em> </em><em>implied</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>name</em><em> </em><em>of </em><em>the</em><em> </em><em>isotope</em><em> </em><em>whereby</em><em> </em><em>the</em><em> </em><em>protons</em><em> </em><em>and</em><em> </em><em>neutrons</em><em> </em><em>add</em><em> </em><em>up</em><em> </em><em>to</em><em> </em><em>its</em><em> </em><em>atomic</em><em> </em><em>number.</em><em> </em><em>So</em>

<em>(</em><em>1</em><em>4</em><em>-</em><em>7</em><em> </em><em>protons</em><em>=</em><em> </em><em>7</em><em> </em><em>neutrons</em><em>.</em><em>)</em>

So it has 7 neutrons.

Tanzania [10]

(p1)(V1)/(T1) = (p2)(V2)/(T2)
(1.00 atm)(V) / (273 + 25K) = (40.0 atm)(V/10) / (273 + T)
273 + T = (40.0)(1/10)(273 + 25K) / (1.00)
T = 919°C

The densities of crystalline co2 and nh3 at 160 k are 1.56 and 0.84 g/cm3, respectively. calculate their molar volumes.
Neporo4naja [7]
The molar volume, symbol Vm<span>, is the </span>volume occupied by one mole of a substance at a given temperature and pressure. <span>It is equal to the </span>molar<span> mass divided by the mass density. Therefore, we calculate as follows:

Vm(CO2) = 44.01 / 1.56 = 28.21 cm^3 / mol
</span>Vm(NH3) = 17.03 / 0.84 = 20.27 cm^3 / mol
