If you were to react 4.3 miles of magnesium phosphide how many moles of potassium would you need?
bixtya [17]

Answer:

25.8

Explanation:

Let's write the reaction between magnesium-phosphide and potassium:

Mg3P2 + K = Mg + K3P

And now let's balance this equation:

Mg3P2+6K=3Mg+2K3P

We see that the ratio of magnesium-phosphide and potassium is 1:6, which means that for every mole of magnesium-phosphide there need to be 6 moles of potassium.

Since we have 4.3 moles of Mg3P2, there need to be 6 • 4.3 = 25.8 moles of potassium.

Draw the product formed when the compound shown below undergoes a reaction with hcl in ch2cl2.
Taya2010 [7]
 The product formed  when HCl and CH2Cl2 react  is   CH4
         H
     H-C- H    methane structure 
         H

  HCl    react with CH2Cl2  to form  methane (CH4) and chlorine gas(Cl2)
that is,

2HCl(g)  + CH2Cl2(l)  = CH4 (g) +2Cl2 (g)

A 36.4-l volume of methane gas is heated from 25°c to 88°c at constant pressure. what is the final volume of the gas?
nignag [31]
<span>using the law pv=nrT and equating these you get the equation v1/t1 = v2/t2 since pressure is constant it also cancels with n and r. show that v1=36.4, t1 = 25 + 273.15 and t2 = 88 +273.15. 273.15 is the Kelvin conversion. then solve for v2. This is 44.1 L.</span>
