Can someone balance this chemical equation for me please : )
Gnoma [55]

Answer:

2

Explanation:

Tried out 1, but couldn't get whole numbers on the right side then, so went up to 2, worked

all four numbrrs: 2, 7, 4, 6

The 7 for oxygen got adjusted in the last step of the thinking, because it's the simplest to adjust.

since there are different prime numbers (or rather numbers that don't share prime factors) in the set, the numbers can't be revived by the same number and still give whole numbers as results (they can't be smaller)

How many moles of neon gas are there 25.0 L of gas or 5.0°C with a pressure of 89.9 KPa?
vladimir2022 [97]
  • Volume=25L
  • Temperature=5°C
  • Pressure=89.9kPa

Now

\\ \rm\rightarrowtail PV=nRT

\\ \rm\rightarrowtail n=\dfrac{PV}{RT}

\\ \rm\rightarrowtail n=\dfrac{89.9(25)}{5R}

\\ \rm\rightarrowtail n=89.9(5)/R

\\ \rm\rightarrowtail n=449.5/R mol

41 g of MgCl^2 is how many moles of magnesium chloride?
kari74 [83]

Answer:

0.43 mol.

Explanation:

  • Knowing that the no. of moles can be calculated using the relation:

<em>no. of moles (n) = mass/molar mass</em>

mass of MgCl₂ = 41.0 g & molar mass of MgCl₂ = 95.211 g/mol.

<em>∴ n = mass/molar mass</em> = (41.0 g)/(95.211 g/mol) = <em>0.43 mol.</em>
