I believe that it would be false. <span>The name of the ion P3- is not phosphoride ion but it is phosphide ion. </span><span>The </span>phosphide ion<span> is P </span>3−<span>, and </span>phosphides<span> of almost every metal in the periodic table are known. They exhibit a wide variety of chemical and physical properties. Hope this answers the question.</span>

How many moles of sulfur are in 80 grams of sulfur?
Norma-Jean [14]

Answer:

2.5 moles

Explanation:

Number of moles = MassMolar mass

= 80⋅g32.06⋅g⋅mol−1 = ??mol

Note that sulfur likely exists in its elemental state as S8. I am perfectly justified in treating sulfur as S. The number of sulfur atoms is the same in each case.

307 g of an unknown mineral is heated to 98.7 °C and placed into a calorimeter that contains 72.4 g of water at 23.6 °C. The hea
RSB [31]

Answer:

0.138 J/g.K

Explanation:

According to the law of conservation of energy, the sum of the heat released bt he mineral and the heats absorbed by the water and the calorimeter is equal to zero.

Qm + Qw + Qc = 0

Qm = - Qw - Qc   [1]

The heat absorbed by the calorimeter can be calculated using the following expression.

Q = C . ΔT

where,

C is the heat capacity

ΔT is the change in temperature

The heat released by the mineral and the one absorbed by the water can be calculated using the following expression.

Q = c . m . ΔT

where,

c is the specific heat capacity

m is the mass

ΔT is the change in temperature

Replacing in [1],

Qm = -Qw - Qc\\c_{m}.m_{m}.\Delta T_{m}=-c_{w}.m_{w}.\Delta T_{w}-C_{c}.\Delta T_{c}\\c_{m}=\frac{-c_{w}.m_{w}.\Delta T_{w}-C_{c}.\Delta T_{c}}{m_{m}.\Delta T_{m}} \\c_{m}=\frac{-(4.18J/g.K).(72.4g).(305.4K-296.6K)-(15.7J/K).(305.4K-296.6K) }{(307g).(305.4K-371.7K)} \\c_{m}=0.138J/g.K
