The numerical value for the Keq of the N2O4 ⇔ 2NO2 is 10 M
calculation
Keq = ( concentration NO)^2/ ( concentration of N2O4)
Keq= (0.5 )^2/0.025 = 10 M
The power of NO2 is taken as 2 as value 2 is is the one in front of No2 in equilibrium equation
To do a balancing to result to a balanced equation, we do elemental balance from each side of the equation. Hence we do separate balances for H, P, O and Ca. In this case, the final balanced equation after balancing elementally is <span>3 Ca(OH)2(aq) + 2 H3Po4(aq) = 6 H2O(l) + Ca3(Po4)2(s)</span>
Answer:
About 0.53 g of carbon dioxide needs to be added.
Explanation:
Recall the ideal gas law:
To determine the amount of carbon dioxide we need, we need to solve for <em>n: </em>
<em /><em />
<em />
Recall that <em>P</em>, <em>V</em>, and <em>T</em> are in atm, L, and K, respectively. <em>R</em> is the universal gas constant.
Convert all values into the correct units:
Volume:
Temperature:
And pressure:
Substitute and evaluate:
Convert moles to grams:
In conclusion, about 0.53 g of carbon dioxide needs to be added.
Answer:
64cm^3
Explanation:
To get the volume just multiple 4*4*4
The Oort cloud sometimes called the Öpik–Oort cloud it was first described in 1950 by Dutch astronomer Jan Oort
