Haemoglobin binds with oxygen and carries along the body. The O 2 is present in the blood diffuses into the cells since the blood ccntain high concentration of oxygen while cells contain a low concentration of oxygen.

Give two uses of dry ice. Dry ice is solid carbon dioxide (similarly to ice of water).It is called dry ice because itgoes from solid to gaseous state without going to liquid phase i.e sublimation (in which instead of solid to liquid to gas it goes through solid to gas). ACCELERATED PLANT GROWTH – A small quantity of CO 2 will increase the.

calculate the amount of carbon dioxide that could be produced when (1) 1 mole of carbon is burnt in air (2) 1 mole of carbon is burnt in 16g of dioxygen (3) 2 mole of carbon are burnt in 16g dioxygen. Answer 9 people found it helpful DIVINEREALM Molecular weight of CO₂ = molecular weight of carbon + molecular weight of dioxygen = 12g + 32g = 44g

Answer: Hydrogen sulphide gas burns in air to give water and sulphur dioxide can be expressed as : H2 S (g) + O2 (g)→H2 O (l) + SO2 (g) To balance this equation, you’re required to write the unbalanced chemical equation. After that, note down the number of atoms of each element that is present on both the reactant side as well as product side.

Step 1: Glycolysis Step 2: Pyruvate oxidation Step 3: The Citric Acid (Krebs) Cycle Step 4: Oxidative Phosphorylation Attributions Learning Objectives Identify the reactants and products of aerobic cellular respiration. Explain each step of aerobic cellular respiration and where in the cell it occurs.

Key to any carbon dioxide removal (CDR) method is that it must durably store billions of tons of CO 2 in places where it cannot easily return to the atmosphere. Quantifying the effectiveness and.

Chemistry The zinc/carbon cell uses a zinc anode and a manganese dioxide cathode; the carbon is added to the cathode to increase conductivity and retain moisture; it is the manganese dioxide that takes part in the reaction, not the carbon. The overall reaction in the cell is: Zn + 2 MnO2 → ZnO + Mn2O3

Respiration – nearly all living cells use oxygen to obtain energy from their food using respiration. This process takes in oxygen from the atmosphere and releases carbon dioxide.

1. What is Nitrogen Dioxide (NO 2)? Nitrogen dioxide is part of a group of gaseous air pollutants produced as a result of road traffic and other fossil fuel combustion processes. Its presence in air contributes to the formation and modification of other air pollutants, such as ozone and particulate matter, and to acid rain

The dot structure for sulfur dioxide has sulfur with a double bond to an oxygen on the left, and two lone pairs of electrons on that oxygen, and the sulfur with a double bond to an oxygen on the right, and two lone pairs of electrons on that oxygen.

Assertion (A): The gas produced during the reaction of sodium carbonate with hydrochloric acid when passed through limewater, turns limewater milky. Reason (R): Carbon dioxide reacts with limewater to form calcium hydrogen carbonate which forms a white precipitate. [0.8 marks]
