Calcium ion (ca2+) is necessary for the clotting of blood and many other physiological processes. a particular alien race has similar physiological processes except their concentration of ca2+ in blood is much higher than in humans. to measure the ca2+ concentration in 1.00 ml of alien blood, sodium oxalate (na2c2o4) solution is added, which precipitates the ca2+ as cac2o4. this solid is dissolved in dilute sulfuric acid to release c2o42latex: -−, and 18.03 ml of 0.644 m potassium permanganate is required to reach the end point. the balanced equation is 2kmno4(aq) + 5cac2o4(s) + 8 h2so4(aq) latex: \longrightarrow⟶ 2mnso4 (aq) + k2so4(aq) + 5caso4(s) +10 co2(g) +8h2o(l) calculate the amount (in mol) of ca2+ in 1.00 ml of alien blood. enter to 4 decimal places

There are 0.0290 moles of Ca⁺² in 1.00 mL of alien blood.

Explanation:

The reactions that take place is:

Ca⁺²(aq) + Na₂C₂O₄(aq) → CaC₂O₄(s) + 2Na⁺

2KMnO₄(aq) + 5CaC₂O₄(s) + 8 H₂SO₄(aq) → 2MnSO₄ (aq) + K₂SO₄(aq) + 5CaSO₄(s) +10 CO₂(g) +8H₂O(l)

It's important to keep this last reaction in mind in order to know the stoichiometric ratio between KMnO₄ and CaC₂O₄.

Using the concentration of KMnO₄ and its volume, we can calculate how many moles there are, then we can convert them into moles of CaC₂O₄ and finally into moles of Ca⁺²:

There are 0.0290 moles of Ca⁺² in 1.00 mL of alien blood.

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck
