Those items float.
Because the items are less dense than water, they float. If they are more dense than water, they sink.
Answer is: there are 3.011·10²³ atoms of calcium.
n(Ca) = 0.50 mol; amount of substance(calcium).
Na = 6.022·10²³ 1/mol; Avogadro's constant or number.
N(Ca) = n(Ca) · Na.
N(Ca) = 0.50 mol · 6.022·10²³ 1/mol.
N(Ca) = 3.011·10²³; number of calcium atoms.
The mole is an SI unit which measures the number of particles in substance. One mole is equal to <span><span>6.022</span></span>·<span><span><span>10</span></span></span>²³<span> atoms.</span>
According to the Gibbs Free Energy equation, some reactions only occur spontaneously at very high temperatures. At high temperatures, the reaction becomes spontaneous if both the entropy as well as the enthalpy are positive.
Changes in Enthalpy, Entropy, as well as Free Energy, Remember that such temperature in the Gibbs free energy equation would be the Kelvin temperature, and as such, it can only be positive. The reaction will constantly be spontaneous at any and all temperatures when H is negative and S is positive, and G's sign is going to be negative.
If a reaction happens without any outside influence, it has been said to as spontaneous. This reaction can release energy and only takes place in the specific circumstances.
Therefore, At high temperatures, the reaction becomes spontaneous if both the entropy as well as the enthalpy are positive.

Answer:
The peritoneum
Explanation:
The peritoneum is the serous membrane that surrounds several organs in the abdominopelvic cavity. The tunica vaginalis is the serous membrane, which surrounds the male gonad, the testis. The two layers of serous membranes are named parietal and visceral. Between the two layers is a thin fluid filled space.
