Moles H2 required = 3 x 0.230=0.690
<span>moles H2 in excess = 0.750 -0.690 =0.060 </span>
<span>the ratio between N2 and NH3 is 1 : 2 </span>
<span>moles NH3 = 0.230 x 2 = 0.460</span>
Answer: Skier 1 will have more potential energy because he is higher than skier 2
Explanation: Gravitational potential energy is the energy possessed by a body by virtue of its position or height.
P.E=
m= mass of the body
g= acceleration due to gravity
h= height of body
Thus if the masses of two bodies are same, the one with greater height possess greater potential energy.
Answer:
824 g
Explanation:
First we <u>convert 7.0 x 10²⁴ formula units of magnesium chloride (MgCl₂) into moles</u>, using <em>Avogadro's number</em>:
- 7.0 x 10²⁴ formula units ÷ 6.023x10²³ formula units/mol = 11.62 mol MgCl₂
There are two Cl moles per MgCl₂ moles, meaning that we have (2 * 11.62) 23.24 moles of Cl
Finally we <u>convert 23.24 moles of chlorine into grams</u>, using <em>chlorine's molar mass</em>:
- 23.24 mol * 35.45 g/mol = 824 g
<u>Because</u> some of the protecting endangered animals habitats overlap with areas that humans count on for their livelihoods.
Osmosis is the diffusion of water from a high concentration to a lower concentration
