What mass of anhydrous solute is needed to prepare 500 mL of 0.032 M NaF(aq)? Answer in units of g.

Answers

Answer 1

Answer: Volume 500 mL in liters : 500 / 1000 = 0.5 L

Molar Mass NaF = 41.98 g/mol

Molarity = 0.032 M

Mass = Molarity * molar mass * volume

Mass = 0.032 * 41.98 * 0.5

= 0.67168 g of NaF(aq)

hope this helps!

Define not matter and give examples

Answers

Answer:

Everything that has mass and takes up space is matter. Every day, you encounter phenomena that either don't have mass or don't take up space. They are non-matter. Basically, any type of energy or any abstract concept is an example of something that is not matter.

There are seven types of crystals. Which of these is not one of the seven?a. triclinic
b. tetraclinic
c. tetragonal
d. orthorhombic

Answers

Answer:

B- Tetraclinic

Explanation:

According to the similarity of their symmetry elements, thirty-two classes are grouped into seven crystal systems: isometric (cubic) system, tetragonal system, hexagonal system, trigonal system (subdivision of the hexagonal system, second North American school of crystallography). , called rhombohedral hexagonal system), orthorhombic system, monoclinic system and triclinic system. Applying the symmetry operations on all possible reticular planes (potential crystal faces) in the seven crystalline systems, according to the 32 symmetry classes, only 48 geometric shapes are possible to be obtained.

Tetraclinic is not one of the seven types of crystal.

Seven types of crystals

The seven types of crystal are triclinic, monoclinic, orthorhombic, tetragonal, trigonal, hexagonal, and cubic while on the other hand, triclinic system is one of the structural categories in which crystalline solids can be assigned.

So we can conclude that Tetraclinic is not one of the seven types of crystal.

the radioactive particle that is positively charged and has two protons and two neutrons is the _____. alpha particle beta particle gamma ray neutron

Answers

Answer: The correct answer is alpha particle.

Explanation:

There are 3 radioactive particles which are released in radioactive decay process:

1. Alpha particle: This particle is released when a nuclei undergoes alpha decay. The particle released has a mass of 4 units and has a charge of 2 units. The particle is positively charged.

$_Z^A\textrm{X}\rightarrow _(Z-2)^(A-4)+_2^4\alpha$

2. Beta-particle: This particle is released when a nuclei undergoes beta decay process. The particle released has a mass of 0 units and has a charge of (-1) units.

$_Z^A\textrm{X}\rightarrow _(Z+1)^A\textrm{Y}+_(-1)^0\beta$

3. Gamma radiations: These radiations are released when an unstable nuclei undergoes gamma ray emission and gives excess energy by a spontaneous electromagnetic process. The radiations does not carry any charge and has no mass.

$_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma$

Hence, the radioactive particle that is charged charged and has two protons and two neutrons is the alpha particle.

it is the alpha particle

When electroplating silver (Ag) on iron (Fe) what is oxidized

Answers

Silver gets oxidized when electroplating silver (Ag) on iron (Fe).

What is electroplating?

Electroplating is basically the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes.

Silver gets oxidized when electroplating silver (Ag) on iron (Fe).

In the process of putting a sliver coating on iron, the iron is the cathode on which the silver ions get reduced.
