Answer: 14 neutrons

Explanation:

the 28 represents the mass number of Aluminum. And Naturally, aluminum has 13 protons (Atomic number)

so to find the number of Neutrons in aluminum, use this relation

Neutron number = mass number - proton or atomic number

substitute the values into it

neutron number = 28-13

neutron number = 15

<em>ther</em><em>efore</em><em> </em><em>,</em><em>ther</em><em>e</em><em> </em><em>are</em><em> </em><em>1</em><em>5</em><em> </em><em>neutr</em><em>ons</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>alumi</em><em>num</em><em> </em><em>atom</em><em>.</em>

Part 1. Determine the molar mass of a 0.622-gram sample of gas having a volume of 2.4 L at 287 K and 0.850 atm. Show your work.
zaharov [31]

If a sample of gas is a 0.622-gram, volume of 2.4 L at 287 K and 0.850 atm. Then the molar mass of the gas is 7.18 g/mol

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates to the macroscopic properties of ideal gases.

An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Given :

  • V = 2.4 L = 0.0024
  • P = 86126.25 Pa
  • T =  287 K
  • m = 0.622
  • R = 8.314

The ideal gas equation is given below.

n = PV/RT

n = 86126.25 x 0.0024 / 8.314 x 287

n = 0.622 / molar mass (n = Avogardos number)

Molar mass =  7.18 g

Hence, the molar mass of a 0.622-gram sample of gas having a volume of 2.4 L at 287 K and 0.850 atm is 7.18 g

More about the ideal gas equation link is given below.

Name 3 common accelerants used in arson
Makovka662 [10]

Answer:

Common ones are Gasoline, Diesel fuel, and Kerosene.

Explanation:

Many accelerants are hydrocarbon-based fuels, sometimes referred to as petroleum distillates: gasoline, diesel fuel, kerosene, turpentine, butane, and various other flammable solvents. These accelerants are also known as ignitable liquids. Ignitable liquids can leave behind tell-tale marks in the fire debris.
