Answer:

K₂EDTA

Explanation:

The additive in the lavender tube is potassium dihydrogen ethylenediaminetetraacetate (K₂EDTA).

EDTA is a powerful chelating agent, that is, it binds strongly to metal cations.

Its main function in hematology labs is to prevent the blood from clotting by binding the Ca²⁺ ions.

When liquid water loses energy, a change in state or chemical identity occurs?
stellarik [79]

Answer:

When most substances lose or gain energy, one of two things happens to the substance: its temperature changes or its state changes. The temperature of a substance is related to the speed of the substance’s particles. So, when the temperature of a substance changes, the speed of the particles also changes. But the temperature of a substance does not change until the change of state is complete.

Explanation:

hope this helps,

Ch4(g) + h2o(g) 3h2(g) + co(g) enthalpy of formation of CH4
Aneli [31]

Answer:

Kc=[[CO][H2]3[CH4][H2O]

3.90=(0.30)(0.10)3[CH4]×0.02

[CH4]=0.023.90×0.30×(0.10)3=5.85×10−2 M

Thus, the concentration of methane in the mixture is 5.85×10−2 M.

A substance is considered more efficient at storing energy when its specific heat enables it to resist changes in temperature. s
joja [24]

Water stores energy more efficiently than air under equal conditions.

It requires more energy to heat water than it does to heat air because water has a significantly larger heat capacity and specific heat than air. Compared to air, which has a specific heat of 1.005 J/g degreesC, water has a specific heat of 4.186 J/g degreesC.

Specific heat:

The amount of heat required to raise the temperature per unit mass is known as specific heat capacity. The heat in Joules required to increase the temperature of 1 gram of sample by 1 Kelvin or degree Celsius is often stated. Water is an excellent temperature regulator since it has a very high specific heat capacity.
