Answer:
<h2>1 ) substances that produce hydrogen atoms in solution.</h2>
Explanation:
A swedist scientist Savante Arhenius give the theory of behaviour of Acid-bases. According to Arhenius ,Arhenius Acid compound produce hydrogen ion or proton upon adding in aqueous solution . Acid are molecular compound that have higly polar covalently bonded ionizable hydrogen atom. HCL is a polar covalently bonded and gas at room temperature and noormal pressure . Upon addition of HCL in water cause ionization ,water breaks into chloride ion and hydrogen ion , in this reaction chlorine gain bond pair electron , while hydrogen ion or proton attached with water . chlorine gain bond pair electron due higher electronegativity than hydrogen and hydrogen loose their electron due to less electronegativity and become hydrogen ion ,these hydrogen ion attached with water to form hydronium ion . Hydronium ion is polyatomic ion .
- Ionization of HCL in water
- formation of polyatomic hydronium ion after HCL ionization in water ,where hydrogen ion attached to water and form polyatomic ion.

Answer:
341m/s
Explanation:
because speed is given by the product of frequency and wavelength, so mathematically we can write ( v=f×lambda)... so in this case we can say speed=170.5×2= 341m/s
:.speed of the wave= 341m/s

Answer:
Option B
Explanation:
Use the Avogadro constant of 6.02 x 10^23
For Option A
1.9 moles x (6.02 x 10^23) = 1.1438 x 10^24
For Option B
5.3 moles x (6.02 x 10^23) = 3.1906 x 10^24
For Option C
9.5 moles x (6.02 x 10^23) = 5.719 x 10^24
For Option D
19.2 moles x (6.02 x 10^23) = 1.1558 x 10^25
The closest to 3.2 x 10^24 is Option B.
How many phases of matter are there?
OA. Two
OC. Four
OD. Five
<h3>B. Three</h3>
=====================================
Regardless of the type of molecule, matter normally exists as either
<h3>a solid, a liquid, or a gas. </h3>
We call this property of matter the phase of the matter. The three normal phases of matter have unique characteristics which are listed on the slide.
