Answer:
What is true of a reaction that has reached equilibrium? The rate of the forward reaction is greater than the rate of the reverse reaction. The rate of the forward reaction is less than the rate of the reverse reaction. The reaction rates of the forward and reverse reactions are equal. The reaction rate is zero.
Explanation:
The pressure of the gas is obtained as 48 atm.
<h3>What is the total pressure?</h3>
Now we know that;
Number of moles of CH4 = 48.0 grams /16 g/mol = 3 moles
Number of moles of H2 = 56.0 grams/2 g/mol = 28 moles
Total number of moles present = 3 moles + 28 moles = 31 moles
Using;
PV =nRT
P = total pressure
V = total volume
n = total number of moles
R = gas constant
T = temperature
P = nRT/V
P = 31 * 0.082 * 286/15
P = 48 atm

They can find out if there are going to be any earthquakes hitting earths surface soon and how big or small they will be and how long and how we should prepare for them
In general, metals will lose electrons to become a positive cation and nonmetals will gain electrons to become a negative anion. Hydrogen is an exception, as it will usually lose its electron. Metalloids and some metals can be can lose or gain electrons. This is not always true, as elements such as nitrogen can lose electrons to become positive. When an ionic compound forms, the more electronegative element will gain electrons and the less electronegative element will lose electrons. Hope this helps :)
