Answer:

10.56L

Explanation:

The following were obtained from the question given :

P1 = 845mmHg

V1 = 4.6L

P2 = 368mmHg

V2 =?

We can calculate the new volume by using Boyle's law as follows;

P1V1 = P2V2

845 x 4.6 = 368 x V2

Divide both side by 368

V2 = (845 x 4.6) / 368

V2 = 10.56L

hammer [34]

Answer: Please see answers in explanation column

Explanation:

Name                Type of sugars

Sucrose               Disaccharide

Sucrose, also called table sugar with molecular formulae C12H22O11  is a disaccharide  composed of two monosaccharides ( 50%glucose + 50%  fructose.).

Lactose                 Disaccharide

 Lactose with molecular formula C12H22O11, found in milk is a disaccharide composed of two monosaccharides (galactose and glucose).

Fructose                 Monosaccharide  

Fructose with molecular formulae C6H12O6 is a natural sugar mostly found in fruits.

Starch                  Polysaccharide

Starch ,a complex carbohydrate with molecular formula  (C6H10O5)n,  is a Polysaccharide containing many  units of glucose joined together by 1,4 linkages. Sources of starch can be found in the parts of plants( roots, tubers etc).

Glucose                 monosaccharides

Glucose, is a simple sugar (monosaccharides) with the molecular formula C6H12O6.  It is found in parts of plants  as well as in humans and known as blood sugar because of its location in the bloodstream.

** worth 20 points + brainliest **
Bad White [126]

Answer : The correct option is, (D) 83^oC

Solution :

Formula used :

Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})

where,

Q = heat released = -1300 J

m = mass of water = 40 g

c = specific heat of water = 4.18J/g^oC      

\Delta T=\text{Change in temperature}  

T_{final} = final temperature = ?

T_{initial} = initial temperature = 91.0^oC

Now put all the given values in the above formula, we get the final temperature of water.

-1300J=40g\times 4.18J/g^oC\times (T_{final}-91.0^oC)

T_{final}=83.2^oC\approx 83^oC

Therefore, the final temperature of the water is, 83^oC

Experiments have shown that the equilibrium constant Kp for the reaction NO(g) + NO2(g) ⇌ N2O3(g) is 0.03. A chamber with a cons
zepelin [54]

Answer:

The reaction will shift to the right

Explanation:

In the reaction:

NO(g) + NO₂(g) ⇌ N₂O₃(g)

Kp of reaction is:

kP = \frac{P_{N_2O_3} }{P_{NO}P_{NO_{2}}} = 0.03

<em>Where P represents the pressures in equilibrium</em>

Replacing in the kP formula the initial pressures:

\frac{50MPa}{200MPa*250MPa} = 0.001

As the <em>Reaction quotient (Q) </em>is less than kP, <em>the reaction will shift to the right </em>producing more N₂O₃ until Q = kP.
