Answer:

the answer is Respiratory epithelium, or airway epithelium, is a type of ciliated columnar epithelium found lining most of the respiratory tract as respiratory mucosa, where it serves to moisten and protect the airways. But I don't see that option here.

earnstyle [38]
 The value  of current  solubility  product  is calculated as  below

K =  (Ag+)( Cl-)

 Ag+  =  0.01 M
Cl-= 1 x10^-5M

K is therefore = 1 x10^-5 x 0.01 = 1 x10  ^ -7 M

The K obtained is greater  than  Ksp

that is    K>  KSp
 1x10^-7 >  1.7 x10 ^-10


will  precipitation  of AgCl form?

yes  the precipitation  of AgCl  will  be formed   since   K> KSP

Predict the most likely bond type for the following.
Amiraneli [1.4K]

Answer:

The three major types of bond are ionic, polar covalent, and covalent bonds. Ionic occurs majorly between metals and non-metals, which allows sharing of electrons to form an ionic compound. Whereas covalent bonding calls for complete transfer of electrons between atoms. Polar covalent bonds have unequaly shared electron-pair between two atoms.

Explanation:

a. Cu (Copper)-<em> ionic bonding </em>

b. KCl (Potassium Chloride) - <em>ionic bonding </em>

c. Si (Silicon) - <em>covalent bonding </em>

d. CdTe (Cadmium Telluride) - <em>polar covalent bonding </em>

e. ZnTe (Zinc Telluride)- <em>polar covalent bonding </em>

How much energy must be added to a 2-kg piece of wood with a specific heat
lesya692 [45]

Answer:

A. 140,800 J

Explanation:

Specific heat of a material is defined as the amount of energy required to increase in 1°C 1kg of the material. <em>For wood there are required 1760J perkg per °C.</em>

The equation is:

Q = C*m*ΔT

<em>Where Q is heat in Joules,</em>

<em>C is specific heat (1760J/kg°C),</em>

<em>m is mass (2kg)</em>

<em>ΔT is change in temperature (50°C - 10°C = 40°C)</em>

Replacing:

Q = 1760J/kg°C*2kg*40°C

Q = 140800J

Right option is:

<h3>A. 140,800 J </h3>
