Answer:
Malachite
Explanation:
Malachite is a copper carbonate hydroxide mineral, with the equation Cu2CO3(OH)2. This dark, green-joined mineral solidifies in the monoclinic precious stone framework, and frequently shapes botryoidal, sinewy, or stalagmitic masses, in cracks and profound, underground spaces, where the water table and aqueous liquids give the way to synthetic precipitation. So, the answer is malachite. Best of Luck!
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.
.
Across the period
Explanation:
Among the element of the main group, the first ionization energy increases across the period.
- The energy required to remove an electron from an atom is called ionization energy.
- The first ionization energy is the energy needed to remove the most loosely bound electron of an atom in the gas phase.
- The ionization energy measures the readiness of an atom to lose an electron.
The magnitude of the ionization energy depends on nuclear charge, atomic radius, sublevel accomodating the electron and the special stability of filled and half-filled sublevels.
Generally, ionization energy increases progressively from left to right due to the decreasing atomic radii.
Down a group, it decreases because atomic radii is increasing

It’s option c. When resources are limited competition will increase => one will survive while other dies=> population will decline.
Good luck
