A substance X which is used as an antacid reacts with dilute hydrochloric acid to produce a gas Y which is used in one type of fire-extinguisher. Name the substance X and gas Y. Write a balanced equation for the chemical reaction which takes place. Medium Solution Verified by Toppr Substance X is Sodium Hydrogen Carbonate and Y is Carbon Dioxide.

why magnesium ribbon is cleaned before burning in air Asked by sy096221 | 12 Sep, 2020, 04:44: PM Expert Answer Dear Student, This question is already answered by our expert. Please follow the given link -

that the following formula is consistent with the FERC approach for calculating LHV of fuels by excluding from the higher heating value of such fuels “the latent heat of water vapor formed in the combustion of hydrocarbon fuels.” See 45 FR 17962. Under this formula, the relationship

6-8 cm magnesium ribbon sanded to remove oxide coating; Bunsen burner, charcoal grill lighter or similar; Tongs; Presentation: Light the burner and adjust the flame to light blue. Holding one end of the magnesium ribbon with tongs, place the other end in the flame until it ignites. The burning ribbon should be held at arm’s length.

Anal Pain. Anal pain is pain that occurs in or around the anus and rectum (the last section of the large intestine that ends in the anus). Causes can include an abscess, hemorrhoids, or Crohn's disease. Diagnosis and treatment are discussed. Northeast Ohio 216.444.7000.

At-home treatments. Home treatments focus on relieving the pain from the spasms. Options include: warm baths or sitz baths; relaxation techniques; over-the-counter pain medications

The magnesium ribbon should be cleaned before burning in the air because the layer of magnesium oxide (which is formed due to the reaction of magnesium with air ) can be removed in order to get the desired chemical reaction. Also in order to remove the oxide layer, the presence of which slowdowns the oxidation process.

We would like to show you a description here but the site won’t allow us.

The answer to the question is c. I and II. The reaction which releases energy and the overall enthalpy change of the reaction is negative is known as an exothermic reaction. The burning of methane releases energy in the form of heat, and the enthalpy change is negative.

Explanation: The magnesium ribbon should be cleaned before burning in the air because the layer of magnesium oxide (which is formed due to the reaction of magnesium with air ) can be removed in order to get the desired chemical reaction. Also in order to remove the oxide layer, the presence of which slowdowns the oxidation process.

Combustion, or burning, is a chemical process that involves releasing energy from a fuel and air mixture. In the case of hydrogen combustion, liquid or gaseous hydrogen is burned in a modified gas-turbine engine to generate thrust.
