Compare and contrast the properties of halogens & alkali metals

Chemistry
1 answer:
zhuklara [117]3 years ago
4 0

Answer:

<u>Physical Properties</u>

Alkali metals are good conductors of heat and electricity while halogens are poor conductors of heat and electricity.

Only specific to Alkali metals: They are soft and can be cut by knife.

<u>Chemical</u><u> </u><u>Properties</u>

Alkali metals have 1 valence electron while halogens have 7 valence electrons.

Alkali metals react with non-metals to form ionic compounds while halogens react with non-metals to form covalent compounds.

You can also look at the trends ( melting/boiling point, reactivity) down their group.

In the reaction below, how many grams of h2o(g) are produced when 2.1 grams o2(g) are consumed? c4h6(g) + o2(g) → co2(g) + h2o(g
amm1812
The balanced equation that illustrates the reaction is:
2C4H6 + 11O2 ......> 8CO2 + 6H2O 

number of moles = mass / molar mass 
number of moles of oxygen = 2.1 / 32 = 0.065625 moles

Now, from the balanced equation, we can note that:
11 moles of oxygen are required to produce 6 moles of water.
Therefore:
0.065625 moles of oxygen will produce:
(0.065625*6) / 11 = 0.03579 moles of water

number of moles = mass / molar mass
mass = number of moles * molar mass
mass of water = 0.03579 * 18 = 0.644 grams

Which reaction represents the process of neutralization? Mg(s)+2HCl(aq) MgCl 2 (aq)+H 2 (g) HCl(aq)+KOH(aq) KCl(aq)+H 2 O(l) C.
Alex

Answer:

HCl(aq) + KOH(aq) --> KCl(aq) + H2O(l)

Explanation:

A neutralization reaction is the process between an acid and a base (there are a number of different ways to define acids and bases). An acid is a compound, which dissolves in water by releasing H+ ions, and a base is a compound, which dissolves in water by releasing OH- ions (by Arrhenius' definition, the simplest one). In this case, the neutralization reaction is the process between HCl (hydrochloric acid) - an acid, and KOH (potassium hydroxide) - a base.
