I think the answer is A: a line that is drawn horizontally around the earth and is parallel to the Prime Meridian
Hope this helps:)
To calculate this you need to interact a sulfate with the copper sulfate therefore when you get a copper sulfate reaction with the oxygen mask level it should create a dance dance revolution of the proxies equaling the new chemical in balance of peace birds hope this
The answer is 1.83 moles of Na.
Answer:
A) chlorine
Explanation:
To solve this question we can use:
PV = nRT
In order to solve the moles of the gas. With the moles and the mass we can find the molar mass of the gas to have an idea of its identy:
PV = nRT
PV / RT = n
<em>Where P is pressure: 603mmHg * (1atm / 760mmHg) = 0.7934atm</em>
<em>V = 100mL = 0.100L</em>
<em>R is gas constant = 0.082atmL/molK</em>
<em>T is absolute temperature = 14°C + 273.15 = 287.15K</em>
0.7934atm*0.100L / 0.082atmL/molK*287.15K = n
3.37x10⁻³ moles of the gas
In 0.239g. The molar mass is:
0.239g / 3.37x10⁻³ moles = 70.9g/mol
The gas with this molar mass is Chlorine, Cl₂:
