Zn(s) + 2 HCl(aq) → ZnCl₂(aq) + H₂(g) 
Oxidation means lose of electrons and increase of positive charge so the part which oxidized in this equation is Zn(s) because it converted to Zn²⁺ (i.e. lost two electrons)

Answer: Zinc (Zn)

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Zn(s)+2HCl(aq)\rightarrow ZnCl_2(aq)+H_2(g)

On reactant side:

Oxidation state of zinc = 0

Oxidation state of hydrogen = +1

On product side:

Oxidation state of zinc = +2

Oxidation state of hydrogen = 0

The oxidation state of zinc increases from 0 to +2, it is getting oxidized and it undergoes oxidation reaction.

The oxidation state of hydrogen decreases from +1 to 0. Thus, it is getting reduced and it undergoes reduction reaction.

Which of the following statements is true of glare control?
galina1969 [7]
The correct option is B. 
Indirect lighting refers to fixtures which direct the light upward to bounce off the wall or ceiling to light a room.

How many grams of KBr is required to prepare 100 mL of<br> 2.0 M KBr solution?
sesenic [268]

Answer:

23.8g

Explanation :

Convert 2.0M into mol using mol= concentration x volume

2.0M x 0.1L (convert 100mL to L since the units for M is mol/L)

= 0.2 mol

We can now find grams by using the molar mass of KBr

=119.023 g/mol (Found online) webqc.org

but can be be calculated by using the molecular weight of K and Br found on the periodic table

We can now calculate the grams by using grams=mol x molar mass

119.023g/mol x 0.2mol

= 23.8046 g

=23.8g (rounded to 1decimal place)
