Answer:
64
Explanation:
Nitrogen combines directly with oxygen at very high temperatures to form nitrogen(ii) oxide. This is the reaction that occurs during lightning flashes. Atmospheric nitrogen and oxygen combines during the high temperatures obtained in lightning flashes to form nitrogen (ii) oxide.
Equation of the reaction is given below:
N(g) + O(g) ---> 2NO(g)
From the equation of the reaction, 1 mole of nitrogen gas combines with one mole of oxygen gas to produce 2 moles of nitrogen (ii) oxide.
Therefore, 2 moles of oxygen gas will react with 2 moles of nitrogen gas
Mass of oxygen gas that is 2 moles of the gas is obtained from the formula; mass = number of moles * molar mass
Molar mass of oxygen gas = 32.0 g/mol
Mass of 2 moles of oxygen gas = 2 * 32.0 = 56 g
Therefore, the mass of oxygen required in grams is 64
The decomposers are at the end of the food chain..
Explanation:
Because, decomposers are the last orgainsms that depends and decomposes all other organisma in the food chain..
<span>Control of maternal glucose levels (< 7.0% in overtly diabetic women) is an important factor in determining fetal outcome. The glycosylated hemoglobin A1c (HbA1c) level is commonly assessed to guide adjustments in the treatment plan throughout pregnancy. Because the maternal serum HbA1c reflects the degree of glycemic control during the preceding 5 to 6 weeks, the test is repeated every trimester. Good diabetic control is reflected by an HbA1c value of 2.5% to 5.9%; an HbA1c value greater than 8% is indicative of poor diabetic control. Because the patient's value indicates good control, the most appropriate action is documentation. The patient may need to see the diabetic nurse educator, depending on other nursing assessments or patient desire.</span>
