Answer:

Cauterization

Explanation:

This procedure is used to destroy some tissues to reduce bleeding and tissue damage, and for  removal of unwanted growth and infections.

It is particularly applicable for treatment where antibiotics are not available for preventing  blood drainage (exsanguination) and cutting of limbs (amputations)

.

Presently, it is been discarded because it facilitate tissue damage and bacterial growth.

However the two types electrocautery and chemical cautery are useful for removing warts not well sighted and stopping of nose bleeding,

Most Bic lighters hold 5.0ml of liquified butane (density = 0.60 g/ml). Calculate the minimum size container you would need to "
Hatshy [7]

Answer:

Volume of container = 0.0012 m³ or 1.2 L or 1200 ml

Explanation:

Volume of butane = 5.0 ml

density = 0.60 g/ml

Room temperature (T) = 293.15 K

Normal pressure (P) = 1 atm = 101,325 pa

Ideal gas constant (R) = 8.3145 J/mole.K)

volume of container V = ?

Solution

To find out the volume of container we use ideal gas equation

PV = nRT

P = pressure

V = volume

n = number of moles

R = gas constant

T = temperature

First we find out number of moles

<em>As Mass = density × volume</em>

mass of butane = 0.60 g/ml ×5.0 ml

mass of butane = 3 g

now find out number of moles (n)

n = mass / molar mass

n = 3 g / 58.12 g/mol

n = 0.05 mol

Now put all values in ideal gas equation

<em>PV = nRt</em>

<em>V = nRT/P</em>

V = (0.05 mol × 8.3145 J/mol.K × 293.15 K) ÷ 101,325 pa

V = 121.87 ÷ 101,325 pa

V = 0.0012 m³ OR 1.2 L OR 1200 ml

Sergeu [11.5K]

Answer:

Solution given:

e) The heating of sodium carbonate to produces sodium oxide and carbon dioxide

Solution given:

<u>Balanced</u><u> </u><u>chemical</u><u> </u><u>equation</u><u>:</u>

\boxed{\bold{\green{Na_{2}CO_{2} +heat \rightarrow Na_{2}O +CO_{2}}}}

<u>when sodium carbonate is heated it decomposed and form sodium oxide and carbon dioxide</u>

<u>f</u>) chromium (III) hydroxide plus sulfuric acid

<u>Balanced chemical equation:</u>

\boxed{\bold{\green{2Cr(OH)_{3}+ 3H_{2}SO_{4} → Cr_{2}(SO_{4})_{3} + 6H_{2}O}}}

<u>When chromium (III) hydroxide react with sulfuric acid double displacement takes place and forms produce chromium(III) sulfate and water.</u>

g) aluminum metal plus chlorine gas

\boxed{\bold{\green{2Al(s) + 3Cl_2(g) \rightarrow 2AlCl_2 }}}

<u>When aluminum metal is added to chlorine gas</u><u> </u><u>Combination reaction takes place and forms aluminum chloride.</u>
