Answer:
To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge. Finally, combine the two ions to form an electrically neutral compound.
Explanation:
Answer:
The correct answer is <em>d. At equilibrium, the forward reaction and reverse reaction will have the same reaction rate.</em>
Explanation:
When a reaction begins, the reactants combine to form products. At the same time of product formation, the convertion of products into reactants also occur. The reaction reaches <em>chemical equilibrium </em>when the rate of forward reaction (the convertion of reactant into products) is equal to the rate of reverse reaction (the convertion of product into reactants). Upon this state, the concentration of reactants and products do not change in time (that does not mean that the concentration of reactants and products are equal, but that once the chemical equilibrium is reached, their concentrations at this point will not vary with the time because the forward and reverse reactions are occuring at the same velocity).

Answer: subduction and sea floor spreading
Explanation:
He knew that the continents today were once joined together by fossil records of plants and animals that were found to be on continents far removed from each other. He knew this also by corresponding land forms that matches up as well. What he couldn’t prove is how the land masses would have moved so far away from each other. Subduction and sea floor spreading move the tectonic plates that the continents sit on. That’s what he was missing.
<h2>Answer:</h2>
Option (B):
The products can form reactants, and the reactants can form products.
<h3>Explanation:</h3><h3>Reversible reaction</h3>
A reversible reaction is a reaction where the reactants form products, which react together to give the reactants back.
aA + bB ⇄ cC + dD
A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B.
Other options are wrong because off:
(A) Concentration changes with time equilibrium concentration and higher product concentration is also possible.
(C) They may be constant.
(D) Concentration changes with time equilibrium concentration and higher reactant concentration is also possible.
