Ph range is 12.53.

<h3>What is PH?</h3>

PH is a proportion of hydrogen particle focus , a proportion of the causticity or alkalinity of an answer. The pH scale for the most part goes from 0 to 14. Fluid arrangements at 25°C with a pH under 7 are acidic, while those with a pH more prominent than 7 are essential or basic. Having a reasonable pH safeguards our bodies from the back to front. Some even say that illnesses and problems can't fill in a body whose pH is in balance. The pH is a logarithmic scale, that is to say, when an answer becomes multiple times more acidic, its pH diminishes by one. In the event that an answer becomes multiple times more acidic, its pH will diminish by two. The pH scale is recognizable to a bunch of standard arrangements whose pH is laid out by peaceful accord. Essential pH standard qualities are resolved utilizing a fixation cell with transaction, by estimating the possible distinction between a hydrogen terminal and a standard cathode like the silver chloride anode.

What is the % yield when 12g of Mg react with HCl to produce 0.2g of H2?
goblinko [34]

Answer:

The yield is 20 %.

Explanation:

Mg + 2 HCl → MgCl2 + H2

(12 g Mg) / (24.30506 g Mg/mol) x (1 mol H2 / 1 mol Mg) x (2.015894 g H2/mol) = 0.9953 g H2.

(0.2 g) / (0.9953 g) = 0.20 = 20% yield

P is the pressure in atmospheres (atm), V is the volume in liters (L), n is the number of moles, R is the gas constant (0.0821 L
yKpoI14uk [10]

Answer:

The mass of the neon gas  m = 1.214 kg

Explanation:

Pressure = 3 atm = 304 k pa

Volume = 0.57 L = 0.00057 m^{3}

Temperature = 75 °c = 348 K

Universal gas constant = 0.0821 \frac{L . atm}{mol K}

We have to change the unit of this constant. it may be written as

Universal gas constant = 8.314 \frac{KJ}{mol K}

Gas constant for neon = \frac{8.314}{20} = 0.41 \frac{KJ}{kg K}

From ideal gas equation,

P V = m R T ------- (1)

We have all the variables except m. so we have to solve this equation for mass (m).

⇒ 304 × 10^{3} × 0.00057 = m × 0.41 × 348

⇒ 173.28 = 142.68 × m

⇒ m = 1.214 kg

This is the mass of the neon gas.

What do the elements within a "period" have in common? (pick one)
Gnesinka [82]

Answer:

All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.

What is a serial dilution?
lord [1]

A serial dilution is the stepwise dilution of a substance in solution. Usually the dilution factor at each step is constant, resulting in a geometric progression of the concentration in a logarithmic fashion.
