Acetylene is the only fuel gas suitable for gas welding because of its favourable flame characteristics of both high temperature and high propagation rates. Other fuel gases, such as propane, propylene or natural gas, produce insufficient heat input for welding but are used for cutting, torch brazing and soldering.

The students in Mrs. Smith's class used pH paper to measure the acidity levels between different samples of breakfast drinks. Th
masya89 [10]

Answer:

The most acidic solution had a pH of 3.27.

Explanation:

In order to solve this problem we need to keep in mind that the lower the pH of a solution is, the more acidic the solution is.

If among the pH readings across the measured breakfast drinks, the lowest one was 3.27 (as the problem tells us with the range), then that drink was the most acidic one.

Conversely, the least acidic one had a pH of 3.88.

Margaret [11]

Answer:

Explanation:

We know that the composition of Steel includes Carbon and Iron. So, if 2g of steel wool was added to the iron acetate, then the iron acetate is now being reduced. What will happen is that the solution will be triggered as it becomes denser and get highly concentrated. Hence, an increase in concentration leads to a decrease in reaction rates. Thus, a slow reaction will take place, and the reaction rate will decrease.
