Rate, fast :Maybe these are the answers.
Since the reaction has one mole of reactants versus two moles of products, the reaction would have a decrease in entropy. One mole of gas exerts less pressure than two moles of gas, and therefore one mole of gas has more entropy than two moles of gas.
Hope this helps
Answer: Type of Chemical Reaction: For this reaction we have a combination reaction. Balancing Strategies: When we add zinc to hydrochloric acid we end up with zinc chloride, a salt, and hydrogen gas. This reaction is actually a good way to make hydrogen gas in the lab.
Answer:
1. Convert given mass of reactant to moles.
2. Convert moles of reactant to moles of product using the coefficients in the balanced equation.
3. Convert moles of product back to grams of product
Explanation:
In order to find out the mass of a given product in grams you would have to convert the grams into moles by multiplying 1 mole over the given mass of the reactant. Then, you would convert the moles of the reactant into moles of the product using mole ratio. And lastly, you would multiply by the mass of the product to calculate the mass back to grams.
