Valentin [98]3 years ago
5 0

Answer:

The microphone will be replacing the sound waves that are captured by the liquid found in the mebranous system.

Explanation:

This mebranous system is made up of noble and very delicate parts such as: the endolymphatic sac, the utriculosacular duct, the saccule, the semicircular canals, the cochlear duct, the utricle and the reuniens duct.

marshall27 [118]

Answer:

1.041g is the maximum sigle dose for the person

Explanation:

The maximum dose for acetaminophen is 15.0mg / kg of body weight for adults

To find the maximum single dosage for a person who weighs 153lb we must convert the lb to kg (1lb = 0.4536kg):

153lb * (0.4536kg / 1lb) =<em> 69.4kg is the mass of the person</em>

<em />

As the maximum dose is 15.0mg / kg, the dose of the person is:

69.4kg * (15.0mg acetaminophen / kg) =

<h3>1041mg = 1.041g is the maximum sigle dose for the person</h3>

The decomposition of NH4HS is endothermic: NH4HS(s)⇌NH3(g)+H2S(g) Part A Which change to an equilibrium mixture of this reaction
shepuryov [24]

Explanation:

According to Le Chatelier's principle, any disturbance caused in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.

As the given reaction is as follows.

       NH_{4}HS(s) \rightleftharpoons NH_{3}(g) + H_{2}S(g)

(a)  When increase the temperature of the reactants or system then equilibrium will shift in forward direction where there is less temperature. It is possible for an endothermic reaction.

Thus, formation of H_{2}S will increase.

  • (b)  When we decrease the volume (at constant temperature) of given reaction mixture then it implies that there will be increase in pressure of the system. So, equilibrium will shift in a direction where there will be decrease in composition of gaseous phase. That is, in the backward direction reaction will shift.

Hence, formation of H_{2}S will decrease with decrease in volume.

  • When we increase the mount of NH_{4}HS then equilibrium will shift in the direction of decrease in concentration that is, in the forward direction.

Thus, we can conclude that formation of H_{2}S will increase then.

What substance is present in a solution consisting solely of electrolytes?
Debora [2.8K]
Electrolytes are substances which are capable of producing a solution that has the ability to conduct electricity. These electrolytes are formed from the dissociation of salts into ions. The positive ions are named cations while the negative ions are termed anions. 

Hence, the answer to these item is SALT. Salt are substances produced by the reaction of cations and anions.

Under strongly acidic conditions aldoses become oxidized to dicarboxylic acids called aldaric acids
horrorfan [7]

Under strongly acidic conditions aldoses become oxidised to dicarboxylic acids called aldaric acids

<h3>What are aldaric acids?</h3>

The formula for aldaric acids is HOOC-(CHOH)n-COOH, and they are a kind of sugar acids in which the sugars' terminal hydroxyl and carbonyl groups have been substituted by terminal carboxylic acids.

Aldoses are often oxidised with nitric acid to produce aldaric acids. The open-chain (polyhydroxyaldehyde) form of the sugar interacts in this reaction.

Aldoses that have both the hydroxyl function of the terminal carbon and the aldehyde function of the first carbon completely oxidised to carboxylic acid functions are referred to as aldaric acids. (Aldonic acid is produced by oxidising just the aldehyde, whereas uronic acid is produced by oxidising only the terminal hydroxyl group.) Like unoxidized sugars, aldaric acids cannot produce cyclic hemiacetals, but they occasionally can form lactose.
