The balanced equation for the reaction between nitrogen and hydrogen to form ammonia is N₂(g) + 3H₂(g) --> 2NH3(g). This uses the concept of balanced chemical equations, which ensure the same number of atoms of each element on both sides.
The reactants in the question are hydrogen and nitrogen, and they react to form the product, ammonia. This reaction can be described using a balanced chemical equation, which ensures that the number of atoms of each element are the same on both the reactant and product sides of the equation.
The balanced equation for this reaction is N₂(g) + 3H₂(g) --> 2NH3(g). Here, N₂ represents nitrogen, H₂ represents hydrogen, and NH₃ represents ammonia. The 'g' in brackets indicates that these compounds are in their gaseous states. The numbers in front of the chemical formulas are called stoichiometric coefficients and they indicate the ratio in which the reactants react and the products form. In this case, one nitrogen molecule reacts with three hydrogen molecules to yield two ammonia molecules.
Chemical reactions, including this one, proceed from left to right as shown by the arrow. They show how reactants become products, similar to mathematical equations.

A. they remain level since densities in both plates are equal.
B. they both push back down into the mantle
C. one plate rides over the other one and forms a trench
D.they buckle upward and form mountains
Answer:
D. They buckle upward and form mountains.
Explanation:
When two plates (either oceanic or terrestrial) converge and they are of similar density then they will crash into each other and form mountains. A great example of this is when India crashed into the Asian continent and the Himalayas were formed.
Answer:
chemical equation
Explanation:
The strength of an acid or a base is determined by the _______ of the substance in solution.
The acid dissociation constant, _______, is a quantitative measure of acid strength. A strong acid has a much _______ Ka than a weak acid. The Ka of an acid is determined from measured _______ values.
Hydrochloric acid and sulfuric acid are _______ ionized in solution and are _______ acids. Ethanoic acid, which is only about 1 percent ionized, is a _______ acid. Magnesium hydroxide and calcium hydroxide are strong _______.
Answer :The corrected answer is given below;
Weak bases react with water to form the hydroxide ion and the conjugate acidof the base. Concentration in solution does not affect whether an acid or a base is strong or weak.
The strength of an acid or a base is determined by the dissociation constant of the substance in solution.
The acid dissociation constant, Ka, is a quantitative measure of acid strength. A strong acid has a much higher Ka than a weak acid. The Ka of an acid is determined from measured titration values.
Hydrochloric acid and sulfuric acid are completely ionized in solution and are strong acids. Ethanoic acid, which is only about 1 percent ionized, is a weak acid. Magnesium hydroxide and calcium hydroxide are strong base.

Explanation:
Weak bases react with water to form the hydroxide ion and the conjugate acid of the base. Concentration in solution does not affect whether an acid or a base is strong or weak.
The strength of an acid or a base is determined by the dissociation constant (ka /Kb) of the substance in solution.
The acid dissociation constant, Ka, is a quantitative measure of acid strength. A strong acid has a much higher Ka than a weak acid. The Ka of an acid is determined from measured titration values.
Hydrochloric acid and sulfuric acid are completely ionized in solution and are strong acids. Ethanoic acid, which is only about 1 percent ionized, is a weak acid. Magnesium hydroxide and calcium hydroxide are strong base.
B. Unequal forces act in unequal times, so the change in momentum for both objects must be equal.
C. Unequal forces act in unequal times, so the change in momentum for both objects must be unequal.
D. Equal forces act in unequal times, so the change in momentum for both objects must be equal.
Answer: Option (A) is the correct answer.
Explanation:
According to Newton's third law of motion, when force is exerted by one body to second body then the second body will also exert a force equal in magnitude and opposite in direction on the first body.
For example, when we hit a wall with our leg then the wall also applies a force on our leg and thus, our leg gets hurt.
Hence, we can conclude that newton's third law says that momentum is conserved in collisions because equal forces act in equal times, so the change in momentum for both objects must be equal.
