The reaction between solid aluminum and liquid bromine is exothermic. This reaction creates
n200080 [17]

Answer:

correct answer is d)

Explanation:

This answer demonstrates law of conservation of mass because the mass of the products is equal to the mass of reactants with the help of the coefficients which is the process known as balancing. This answer also includes the correct formulas, as Br is a gas so it MUST be written as Br2. hope this helps:)

A helium filled ballon at sea level gas a volume of 2.1L at 0.998 atm and 36C if it is released and rises to an elevation where
expeople1 [14]

Answer:

                      2.268 L

Explanation:

              According to Ideal Gas Law, " The Volume of a given mass of gas is inversely proportional to the applied Pressure and directly proportional to applied temperature, ". Mathematically the initial and final states of gas are given as,

                                     P₁ V₁ / T₁ =  P₂ V₂ / T₂   ----------- (1)

Data Given;

                  P₁  =  0.998 atm

                  V₁  =  2.1 L

                  T₁  =  36 °C  =  309 K

                  P₂  =  0.90 atm

                  T₂  =  28 °C  =  301 K

                  V₂  =  ??

Solving equation 1 for P₂,

                   V₂  =  P₁ V₁ T₂ / T₁ P₂

Putting values,

                   V₂  =  (0.998 atm × 2.1 L × 301 K) ÷ (309 K × 0.90 atm)

                   V₂  =  2.268 L

The ph of 0.010 m aqueous aniline is 8.32. What is the percentage protonated?
LekaFEV [45]

Answer : The percentage aniline protonated is, 0.0209 %

Explanation :

First we have to calculate the pOH.

pH+pOH=14\\\\pOH=14-pH\\\\pOH=14-8.32\\\\pOH=5.68

Now we have to calculate the hydroxide ion concentration.

pOH=-\log [OH^-]

5.68=-\log [OH^-]

[OH^-]=2.09\times 10^{-6}M

The equilibrium chemical reaction will be:

NH_3+H_2O\rightleftharpoons NH_4^++OH^-

From the reaction we conclude that,

Concentration of OH^- ion = Concentration of NH_4^+ ion = 2.09\times 10^{-6}M

Now we have to calculate the percentage aniline protonated.

\text{percentage aniline protonated}=\frac{2.09\times 10^{-6}M}{0.010M}\times 100

\text{percentage aniline protonated}=0.0209\%

Thus, the percentage aniline protonated is, 0.0209 %

<em>Explanation:</em>

According to rules of significant figure

0.052301 km have 5 significant figure:

  • Zero to the left of the first non zero digit not significant.
  • Zero between the non zero digits are significant.

<em>400 cm have 1 significant figure:</em>

  • Trailing zeros are not significant in numbers without decimal points.

<em>50.0 m  have 3 significant figure:</em>

  • Trailing zeros are significant in numbers when there is decimal points.

<em>4500.01 ml have 6 significant figure:</em>

  • Zero between the non zero digits are significant.
