Answer:
Explanation:
Formula
density = mass / volume
Givens
mass = 26.94
volume = 2.568
Solution
density = 26.94 / 2.568
density = 10.49 grams / cc^3
Answer

silver is as above
copper is a bit over 8.
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:
Dominant traits are traits that more likely to be transferred from a parent to an offspring so scientist use this term dominant.
Answer:
Explanation:
Dalton’s Atomic Theory
All elements are composed of tiny indivisible particles called atoms.
All atoms of the same element are identical.
Atoms of different elements are different(they have different sizes, masses, chemical properties, etc.).
Atoms of different elements can combine with each other in simple whole number ratios to form compounds. (Law of Definite Proportions).
Chemical reactions occur when atoms are separated, joined, or rearranged. However, atoms of one element are NOT changed into atoms of another element by a chemical reaction. (Law of Conservation of Mass).
