2H(+) + SO4(2-) + Ca(2+) + 2I(-) -> CaSO4(s) + 2H(+) + 2I(-)
The signs in brackets are the subscripts for the charge of the ion. This is the complete ionic equation. The net ionic equation is:
Ca(2+) + SO4(2-) -> CaSO4

Answer:

SO₄²⁻(aq) + Ca²⁺(aq) → CaSO₄(s)

Explanation:

Given equation:

H₂SO₄(aq) + Cal₂(aq) → CaSO₄(s) + 2HI(aq)

Ionic equation:

2H⁺(aq) + SO₄²⁻(aq) + Ca²⁺(aq) + 2I⁻(aq) → CaSO₄(s) + 2H⁺ (aq) + 2I⁻(aq)

Net ionic equation:

SO₄²⁻(aq) + Ca²⁺(aq) → CaSO₄(s)

2H⁺ (aq) and 2I⁻(aq) ions are common on both side of the equation hence they were eliminated. (aq) here means that the ions are in aqueous phase and (s) means solid or precipitate. CaSO₄ forms a white precipitate which does not ionize in the aqueous phase.

What relationship exists between an enzyme and a catalyst?
shepuryov [24]

A catalyst is a chemical that increases the rate of a chemical reaction without itself being changed by the reaction. The fact that they aren't changed by participating in a reaction distinguishes catalysts from substrates, which are the reactants on which catalysts work. Enzymes catalyze biochemical reactions.

How might cell division help multicellular organisms maintain and repair cells
Komok [63]
Because when the cells divide (resulting in more cells) the multicellular organism mantains its strong cells and when one cell is damaged the other cells compensate for that damaged cell.

Find the volume in milliliters of 2.00 mol of an ideal gas at 36°C and a pressure of 1120 torr.
hram777 [196]

Answer:

V = 34430 mL

Explanation:

Given data:

Volume in mL = ?

Number of moles of gas = 2.00 mol

Temperature = 36°C (36+273= 309K)

Pressure of gas = 1120 torr

Solution:

Formula:

PV = nRT

V = nRT/P

V = 2.00 mol ×62.4 torr • L/mol · K × 309K / 1120 torr

V = 38563.2 torr • L / 1120 torr

V = 34.43 L

L to mL

34.43 L ×1000 mL / 1 L

34430 mL
