Answer:

Explanation:

Chemical equation:

2NaOH(aq) + Pb(ClO₃)₂(aq)    →  2NaClO₃(aq)  + Pb(OH)₂(s)

The given reaction is example of double displacement reaction. It is also known as double replacement reaction. The cation and anion of both reactants exchange with each others.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD

Chemical equation:

CH₄(g)  + 2O₂(g)    →  CO₂(g) + 2H₂O(l)

The given reaction is example of combustion. In this reaction hydrocarbons burn in the presence of oxygen and produces water and carbon dioxide.

Chemical equation:

2AgNO₃(aq) + Zn(s)    →    Zn(NO₃)₂(aq) + 2Ag(s)

The given reaction is example of single displacement reaction. It is also known as single replacement reaction. Zinc is more reactive than silver it replace the silver from nitrate and form zinc nitrate.

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Chemical equation:

HI(aq) + LiOH(aq)     →     H₂O(l) + LiI(aq)

The given reaction is example of double displacement reaction. It is also known as double replacement reaction. The cation and anion of both reactants exchange with each others.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD

The volume of blood plasma in adults is 3.1 L. it's density is 1.03 g/cm3. Approximately how many pounds of blood plasma are the
e-lub [12.9K]
The important thing in this question is the unit. The mass equals density * volume. 3.1 L = 3.1 * 10^3 cm3. So the mass is 3.193*10^3 g. 1 pound = 453.95 g. So the answer is 7.04 pounds.

Micky Mo is a 64-year-old male admitted to the emergency room for asthma. His laboratory results are as follows: pH 7.31, pCO2 h
Salsk061 [2.6K]

Answer:

Micky Mo is suffering from respiratory acidosis.

Explanation:

The pCO2 level in micky"s body is higher than normal it means the excess amount of  CO2 will reacts with water to generate carbonic acid(H2CO3).

  On the other hand according to the question total HCO3- also higher than normal.As a result the excess HCO3- will react with proton to form carbonic acid which is in turn dissociate to generate CO2 and H2O to maintain normal acid base homeostasis.

 From that point of view it can be said Micky Mo is suffering from respiratory acidosis.

IF you’ve eaten 45% of a box of chocolate cereal that has 13oz when you buy it how many oz of the cereal have you eaten
weqwewe [10]
To determine the number of ounces of the chocolate cereal that you have eaten, the operation that needs to be performed is simply the multiplication of the initial number of ounce in the box of cereal and the decimal equivalent of the given percentage. If we let n be the answer, 
   
    n = (13 oz)(0.45) 
 
Simplifying, this will give us the answer which is equal to 5.85 oz.

<em>Answer: 5.85 oz. </em>
