<span>Activity series of metals. it is a series of metals based on their reactivity from highest to lowest. Potassium occupies the top most level of reactivity. The reactivity means the ability to displace hydrogen gas from water and acid solutions.</span>
<span>Answer:
(4.184 J/g·°C) x (185 g) x (24.70 - 21.00)âC = 2863.948 J = 2.86 kJ
(2.86 kJ) / (2.00 mol) = 1.43 kJ/mol</span>
Answer:
Ethyne, C2H2, has a 5 covalent bond between the two carbon atoms.
ethane C2H6, has a 6 covalent bond
Explanation:
Ethyne are covalent compounds since these compound involve bonding between two non metals. In H2S H 2 S , the compound is formed when sulfur shares two of its valence electrons with two hydrogen atoms through a covalent bond
Ethane
6 bonds between C−H and one is between C−C. The six hydrogen atoms will each share their 1 electron with carbon to form six carbon-hydrogen covalent bonds. The two carbon atoms will each share their 1 electron to form one carbon-carbon covalent bond
