Answer: 702.2 mmHg

Explanation: According to Dalton's law of partial pressure, the total pressure is the sum of partial pressures of individual components.

P=pH_2O+pH_2

P=total pressure

pH_2O= partial pressure of water

pH_2 = partial pressure of hydrogen

partial pressure of H_2O at 30°C is 31.8 mmHg

734 mmHg = 31.8 mmHg + pH_2

pH_2 = 702.2 mmHg

At a temperature of 30 deg C, the vapour pressure of water H2O is about 32 mm Hg. Therefore at a total pressure f 734 mm Hg, the partial pressure of the Hydrogen gas collected is:

<span>P Hydrogen = 734 mm Hg – 32 mm Hg = 702 mm Hg</span>

Which has the largest atomic radius magnesium silicon sulfur or sodium the smallest
Monica [59]

Therefore the largest atoms are on the left and the smallest on the right. So sodium (Na) has the largest atomic radius, as the valence electrons are the least attracted to the nucleus

Jessica has 12.7 moles of a compound for an experiment. How many particles of the compound does she have?
guajiro [1.7K]

Answer:

Number of moles is defined as the ratio of given mass in g to the molar mass.The mathematical expression is given as:

Number of moles  =Number of moles of compound  = 12.7 moles (given)As, 1 mole of any compound is equal to  particles.

where,    is Avogadro number. Formula for calculating particles is given by:

where, N =  number of particles, n = number of moles and  is Avogadro number.

Put the values,=  or  Hence, number of particles of the compound is equal to
