Heat required to raise the temperature = 159.505 J

<h3>Further explanation</h3>

Given

c = specific heat of Beryllium = 1.825 J/g C

m = mass = 2.3 g

Δt = Temperature difference : 60 - 22 = 38 °C

Required

Heat required

Solution

Heat can be formulated

Q = m.c.Δt

Input the value :

Q = 2.3 x 1.825 x 38

Q = 159.505 J

Compare a sodium ion and neutral sodium atom in size. what causes the size difference

n200080 [17]

A cation is smaller than its parent atom.
Therefore, here a sodium ion is smaller than the neutral sodium atom.

Reason: Since the sodium atom loses an electron to form an electropositive ion(cation), its nuclear charge increases(the number of protons exceeds the number of electrons) and the orbital electrons are pulled with a greater energy.
Thus,the sodium ion shrinks in size.

Write a net ionic equation to show that acetylsalicylic acid (aspirin), hc9h7o4, behaves as a brÃ¸nsted-lowry acid in water.

Thepotemich [5.8K]

By definition, Bronsted-Lowry acid is a proton donor in the acid-base neutralization reaction. When a weak acid like acetylsalicylic acid is reacted with water, the water here acts as the Bronsted-Lowry base. This is possible because water has properties of amphoterism - can act as an acid or base. In this case, acetylsalicylic acid would have to donate its H+ atom to water, so that it would yield a hydronium ion, H₃O⁺. The complete net ionic reaction is shown in the picture.

So, in the reaction, the products yield are the acetylsalicylate ion and the hydronium ion.
