Inessa [10]2 years ago
4 0

The statement which is true about <em>Atom A</em> and <em>Atom B</em> is; Choice B: <em>Atom B will give up electrons to form bonds.</em>

According to the question;

For Atom A:

  • It has 7 electrons

  • the electron configuration is; <em>1s²2s²2p³</em>

  • Therefore, it has 5 valence electrons.

For atom B:

  • It has 13 electrons

  • the electron configuration is; <em>1s²2s²2p⁶3s²3p¹</em>

  • Therefore, it has 3 valence electrons.

Since, electrons need 8 electrons to assume a full octet;

Consequently, Atom B will give up electrons to become stable.

Sample cost = $15.796

<h3>Further explanation</h3>

Given

Mass = 2 g

Density = 0.718 g/ml

Cost =  $5.67 per mL

Required

Cost

Solution

The density : the ratio of mass and volume

Can be formulated :

Density (ρ) = m : V

The volume of the liquid :

V = m : ρ

V = 2 g : 0.718 g/ml

V = 2.786 ml

Sample cost :

= 2.786 ml x $5.67/ml

= $15.796

Questions to be ask for testing a starch
ddd [48]
I'm assuming you're asking how to test for a starch,


To do so you do this thing called the "Iodine Test"
The potassium iodide aqueous solution will form this complex with starch to form a purplish-blue color.

However, watch out for the pH as hydrolysis of starch could occur to prevent the test from working out-- and the temperature as the greater it is, the less intense the color is

What is the molar concentration (molarity) of a solution made by dissolving 0.285 moles of CaCl2(s) in just enough water to form
marusya05 [52]

Answer:

The answer to your question is Molarity = 0.238

Explanation:

Data

Molarity = ?

number of moles = 0.285

volume = 1.2 L

Molarity is a unit of concentration that relates the moles of a substance by the volume in liters.

Formula

Molarity = moles / volume

Substitution

Molarity = 0.285 / 1.2

Simplification and result

Molarity = 0.238
