Answer:
Explanation:
Hello!
In this case, since this a reaction in which the oxidation state of the metals is changing, we need to apply a redox method for which:
Thus, the result is:

Answer:
10.
Explanation:
Hello,
In this case, for the given reaction:
By knowing the law of conservation of mass must be respected, the following coefficients do balance the chemical equation:
So the sum of all the coefficients is 10.
Regards.
Answer:
Explanation:
Let's consider the following reaction.
CO(g) + 2 H₂(g) ⇌ CH₃OH(g)
The equilibrium constant (Kc) is <em>the products of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients.</em>
If you wanted to calculate [CH₃OH], suppose that the molar concentrations for CO and H₂ at equilibrium are [CO] = 0.04 M and [H₂] = 0.08 M. The concentration of methanol at equilibrium is:
Answer:
recycle and dispose of trash properly
minimize use of fertilizer
use environmentally friendly modes of transportation
scientists say creating marine refuges where fishing, mining, and recreating are off limits, make the reefs healthier, and so more resilient
