536 cm (bigger or smaller than) 53.6 dm The Correct Answer and Explanation is: To compare 536 cm and 53.6 dm, let’s first convert the measurements to the same unit. Thus, 536 cm is equal to 53.6 dm. Explanation: Both measurements, after converting from decimeters to centimeters, represent the same length. The initial confusion may

536 cm greater than or less than 53.6 dm The Correct Answer and Explanation is: To compare 536 cm (centimeters) with 53.6 dm (decimeters), we need to convert one of them so that both measurements are in the same unit. Since both measurements are exactly equal, 536 cm is equal to 53.6 dm. Explanation: The

To convert mph to km/h, multiply by 1.6 calculate in km/h the speed of a train traveling 75 mph? The Correct Answer and Explanation is: To convert 75 mph to km/h, we use the given conversion factor: 1 mph = 1.6 km/h. Now, multiply the speed of the train in miles per hour (mph) by

Name the hydrate BaCl2·2H2O(s). Spelling counts. The Correct Answer and Explanation is: The hydrate barium chloride dihydrate is the name of the compound with the chemical formula BaCl2·2H2O(s). In naming hydrates, the first part of the name is the name of the anhydrous (water-free) compound, which in this case is barium chloride (BaCl2). The second
