What happens to the atomic mass of an element moving from left to right within a period​

Chemistry
1 answer:
JulsSmile [24]3 years ago
4 0

Answer:

As you move across a period, the atomic mass increases because the atomic number also increases. ... The atomic mass for any given atom mainly comes from the mass of the protons and neutrons.

What is the osmotic pressure of a 0.850 m solution of glucose in water at 35 °c?
Alik [6]

The osmotic pressure of the glucose solution is 21.49 atm.

From the question given above, the following data were obtained:

  • Molarity (M) = 0.85 M
  • Temperature (T) = 35 °C = 35 + 273 = 308 K
  • Van't Hoff's factor (i) = 1 (non-electrolyte)
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Osmotic pressure (π) =?

π = iMRT

π = 1 × 0.85 × 0.0821 × 308

π = 21.49 atm

Therefore, the osmotic pressure is 21.49 atm

The weak acid HZ has a Ka of 2.55x10⁻⁴.(a) Calculate the pH of 0.075 M HZ.
Dima020 [189]

<u>2.37</u> is the pH of 0.075 M HZ.

<h3>What is pH?</h3>

The term pH, which originally stood for "potential of hydrogen" (or "power of hydrogen"), is used in chemistry to describe how acidic or basic an aqueous solution is. Lower pH values are summarized for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions.

The pH scale is inversely indicates to the concentration of hydrogen ions in the solution and is logarithmic.

⇒pH = -log(a_{H+})

Acidic solutions are those with a pH below 7, and basic solutions are those with a pH above 7, at a temperature of 25 °C (77 °F). At this temperature, solutions with a pH of 7 are neutral (e.g. pure water). The pH neutrality relies on temperature, falling below 7 if the temperature rises above 25 °C.
