2. Arnie is going to dissolve 2.65g of zinc using 6.0M hydrochloric acid. A) what volume of the acid will he need to dissolve al
fenix001 [56]

Answer:

Explanation:

Zn + 2HCl = ZnCl₂ + H₂

A ) mole of Zn = 2.65 / 65

= .04 mol

mole of HCl required = .04 x 2 mol

.08 mol

If v be the volume required

v x 6 = .08

v = .0133 liter

= 13.3 cc

B )

volume of gas at NTP :

moles of gas  obtained = .04 moles

= 22.4 x .04 liter

= .896 liter

we have to find this volume at given temperature and pressure

\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}

\frac{760\times.896}{273} =\frac{628\times V_2}{296}

V_2 = 1.175 liter.

C )

.04 mole of zinc chloride will be produced

mol weight of zinc chloride

= 65 + 35.5 x 2

= 136 gm

.04 mole = 136 x .04

= 5.44 gm

Helium (He), oxygen (O), carbon (C) fluorine (F), and chlorine (Cl) are all nonmetals. Using the periodic table, which pair of n
Delicious77 [7]

Answer:

fluorine (F), and chlorine (Cl) because they are both halogens and belong to the same group in the periodic table

Explanation:

The pair of non - metals in the elements given that will have similar properties are chlorine and Fluorine.

This is because they both are elements commonly known by the group name Halogens which belong to group 7A.

Properties of halogens include;

- They are very reactive, have single covalent bonds and readily form other compounds.

- In the gaseous state, they will form diatomic covalent molecules.

Whereas, helium is a group 8 element, oxygen is a group 6 element while carbon is a group 4 element.
