When sodium is put in water, the metal floats on the surface and reacts to form sodium

Chemistry

Answer: Sodium also floats on the surface, but enough heat is given off to melt the sodium (sodium has a lower melting point than lithium and the reaction produces heat faster) and it melts almost at once to form a small silvery ball that dashes around the surface.

Answer:

hydroxide.

Explanation:

Alkali metals are in group 1 of the Periodic Table. They are on the left of the Periodic Table. These are the alkali metals as follows:

  • Lithium
  • Sodium
  • Potassium
  • Rubidium
  • Caesium
  • Francium

When alkali metals react with water they make alkaline solutions, so the universal indicator turns people and they produce hydrogen and a metal hydroxide. When sodium is put in water, the metal floats on the surface it reacts to form sodium hydroxide and hydrogen.

Calculate the mass of 29.8 mL of aluminum, which has a density of 2.00 g/mL.
MaRussiya [10]

Answer:

The answer is

<h2>59.6 g </h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

Density of aluminum = 2.00 g/mL

volume = 29.8 mL

The mass is

mass = 2 × 29.8

We have the final answer as

<h3>59.6 g</h3>

Hope this helps you

The ka of hf is 6.8 x 10-4. what is the ph of a 0.35 m solution of hf?
damaskus [11]
When the reaction equation is:

HF ↔ H+   +   F-

and when the Ka expression
= concentration of products/concentration of reactions

so, Ka = [H+][F-]/[HF]

when we assume:

[H+] = [F-] = X

and [HF] = 0.35 - X

So, by substitution:

6.8 x 10^-4 = X^2 / (0.35 - X) by solving for X

∴ X = 0.015 M

∴[H+] = X = 0.015

when PH = -㏒[H+]

∴PH = -㏒0.015

        = 1.8
