Answer:
3, H⁺ acceptor
Explanation:
Let's consider Bronsted-Lowry acid-base theory.
According to this theory, an acid is a substance that donates H⁺ ions. For example, HCl is an acid.
HCl + H₂O = Cl⁻ + H₃O⁺
Cl⁻ is the conjugate base of HCl.
According to this theory, a base is a substance that accepts H⁺ ions. For example, NH₃ is a base.
NH₃ + H₂O = NH₄⁺ + OH⁻
NH₄⁺ is the conjugate acid of NH₃.
Answer:
Molar mass of P₂O₅ = 141.948 g/mol which is approximately 142 g/mol.
Explanation:
Molar mass of AlCl₃
Molar mass = 26.982 + 35.5 × 3 = 133.32 g/mol
Molar mass of BaCl₂
Molar mass = 137.33 + 35.5 × 2 = 208.33 g/mol
Molar mass of MgCl₂
Molar mass = 24.305 + 35.5×2 = 95.305 g/mol
Molar mass of P₂O₅
Molar mass = 30.974×2 + 16× 5 = 141.948 g/mol
Answer:
Hey mate....
Explanation:
This is ur answer.....
<em>Iron is an essential element for blood production. About 70 percent of your body's iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin. Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Myoglobin, in muscle cells, accepts, stores, transports and releases oxygen.</em><em> </em><em>About 6 percent of body iron is a component of certain proteins, essential for respiration and energy metabolism, and as a component of enzymes involved in the synthesis of collagen and some neurotransmitters. Iron also is needed for proper immune function.</em><em> </em><em>About 25 percent of the iron in the body is stored as ferritin, found in cells and circulates in the blood. The average adult male has about 1,000 mg of stored iron (enough for about three years), whereas women on average have only about 300 mg (enough for about six months). When iron intake is chronically low, stores can become depleted, decreasing hemoglobin levels.</em><em> </em><em>When iron stores are exhausted, the condition is called iron depletion. Further decreases may be called iron-deficient erythropoiesis and still further decreases produce iron deficiency anemia.</em>
