Answer:

1. it is symbolized as 4/2 He : Alpha rays

2. it has the weakest penetrating power : Alpha rays

3. It is a high-speed electron : beta rays

4. It possesses neither mass nor charge : gamma rays

5. it has the strongest penetrating power : beta rays

6. its is symbolized as 0/-1e : beta rays

7. it is the most massive of all the components: alpha rays

Explanation:

Let us consider the characteristics of each of the given rays.

α rays: These are helium nucleus so are symbolized by $He^{4}_{2}$

Due to two protons and two neutrons unlike beta and gamma rays these are the most massive and thus have least penetrating power among the three given rays.

β rays: These are actually high speed electrons and are symbolized as $^{0}_{-1}e$ . Due to lesser mass than alpha rays they are more penetrating than them however less penetrating than gamma rays.

γ rays : They carry no charge or mass. Due to least massive among the three rays they have highest penetrating power.

A complex, ML₆²⁺, is violet. The same metal forms a complex with another ligand, Q, that creates a weaker field. What color migh

Bingel [31]

A complex, ML₆²⁺, is violet. The same metal forms a complex with another ligand, Q, that creates a weaker field. MQ₆²⁺, be expected to show green color.

<h3>What is spectrochemical series?</h3>

The ligands (attachment to a metal ion) are listed in the spectrochemical series according to the strength of their field. The series has been created by superimposing several sequences discovered through spectroscopic research because it is impossible to produce the full series by examining complexes with a single metal ion. The halides are referred to be weak-field ligands whereas the ligands cyanide and CO are strong-field ligands. Medium field effects are claimed to be produced by ligands like water and ammonia.

Measurements show that unknown compound X has the following composition: element mass % carbon 41.0% hydrogen 4.58% oxygen 54.6%

anastassius [24]

Answer:

CHO

Explanation:

Carbon = 41%, Hydrogen = 4.58%, oxygen = 54.6%

Step 1:

Divide through by their respective relative atomic masses

41/ 12, 4.58/1, 54.6/16

3.41 4.58 3.41

Step 2:

Divide by the lowest ratio:

3.41/3.41, 4.58/3.41, 3.41/3.41

1, 1, 1

Hence the empirical formula is CHO

What is the concentration of a solution that has 15.0 g NaCl dissolved to a total of 750 ml?

Oksana_A [137]

<u>Answer:</u> The concentration of solution is 0.342 M

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Mass of solute (Sodium chloride) = 15 g

Molar mass of sodium chloride = 58.5 g/mol

Volume of solution = 750 mL

Putting values in above equation, we get:

$\text{Molarity of solution}=\frac{15g\times 1000}{58.5g/mol\times 750mL}\\\\\text{Molarity of solution}=0.342M$

Hence, the concentration of solution is 0.342 M
