How many atoms of potassium need to react with nitrogen in order to produce 2.0 moles of potassium nitride?
To produce potassium nitride (K₃N), the balanced chemical equation is 6 K + N₂ → 2 K₃N. This indicates that 6 moles of potassium are required to produce 2 moles of potassium nitride. Therefore, to produce 2.0 moles of K₃N, you would need 6 moles of potassium.
Why is baby born with more white blood cells?
Red blood count is higher in infants as compared in adults. This is probably so because the growth in infants is very fast. Infants gain three times weight in first year of his life. By the second year the weight gain is only 20 %. So infants need more oxygen carrying capacity in the blood. That is why RBC count is more in infants as compared to adults.
Is lithium more reactive than copper?
Yes, potassium is more reactive than lithium, since although they both need to lose one electron to have full outer shells, potassium's outer electron is furthest from the positive attractions of the nucleus. Therefore, it is easier for potassium to lose its outer electron than it is for lithium. hope that helped
How many moles potassium chlorate must be used to produce 6 moles of oxygen gas?
We need 3 moles of potassium perchlorate.
How many mol of potassium are represented by 7.85e23 potassium atoms?
To find the number of moles of potassium, we need to first determine the molar quantity of potassium atoms in one mole. A mole is equivalent to Avogadro's number, which is 6.022e23 atoms per mole. So, 7.85e23 potassium atoms would be approximately 1.304 moles of potassium.
What is the maximum daily amount of potassium?
Recommended Daily Allowance (RDA) : 3500 milligrams On a blood test from a lab, they report on a single unit scale, and most adults need between 2 to 5 on the test. If you have numbers above that, you may experience heart problems. Most minerals can be quite harmful if done to excess.
