Web2H 2+O 2→2H 2O Medium Solution Verified by Toppr A reducing agent is an element that loses electrons. The reducing agent means to lose electrons; it is said to have been oxidized. The element which undergoes oxidation (gets oxidized) is called reducing agent. H 2 is reducing agent. 2H 2+O 2→2H 2O WebSep 13, 2024 · (1) M n O 2 ( s) + 4 H + ( a q) + 2 C l − ( a q) → M n 2 + ( a q) + 2 H 2 O ( l) + C l 2 ( g) For the reaction, 2 N O 2 ( g) + 7 H 2 ( g) → 2 N H 3 ( g) + 4 H 2 O ( g), is hydrogen an oxidizing agent or a reducing agent? Explain. An element that is oxidized is a (n) __________ agent and an element that is reduced is a (n) __________ agent.
What are the elements names and how many atoms are in 2H2SO4?
WebAn atom of a free element has an oxidation number of 0 0 0 0. For example, each C l \ce{Cl} C l C, l atom in C l X 2 \ce{Cl2} C l X 2 has an oxidation number of 0 0 0 0. The same is true for each H \ce{H} H H atom in H X 2 \ce{H2} H X 2 , … WebJul 20, 2024 · Atomic mass of one molecule of H2SO4 is 98 Atomic mass unit. Atomic mass of one mole of H2SO4 is 98 grams. So 98 grams of H2SO4 contains 1 mole of H2SO4 molecule i.e., 7 moles atoms. So, by applying the basic maths, we get 49 grams of H2SO4 contains 1/2 mole of H2SO4 molecule i.e., 3.5 moles atoms.

WebQuestion: Chlorine gas was first prepared in 1774 by the oxidation of NaCl with MnO2: 2NaCl (s) + 2H2SO4 (l) + MnO2 (s) ---> Na2SO4 (s) + MnSO4 (s) + 2H2O (g) + Cl2 (g) Assume that the gas produced is saturated with water vapor at a partial pressure of 28.7 mm Hg and that it has a volume of 0.597L at 27C and 755 mm Hg pressure. Web13. The pressure of a sample of gas is measured at sea level with a closed-end manometer. The liquid in the manometer is mercury. Determine the pressure of the gas in: (a) torr. (b) Pa. (c) bar. 14. The pressure of a sample of gas is measured with an open-end manometer, partially shown to the right. WebFeb 5, 2024 · So we have a molecule of sulfuric acid, which we represent as (O =)2S(OH)2.
