Answer:

c

Explanation:

because the left side of reactant is take more time to make a product than the first

The rate of these reactions should be considered as the option b. The rate of reaction A is lower.

Since Reaction A is completed in 12 seconds, and reaction B is completed in 21 seconds.

So based on this, we can say that the rate of reaction A should be lower as it contain 12 seconds as compared to reaction b.

hence, the option b is correct.

Answer:

Q = 450 J

Explanation:

Given that,

Mass of a piece of glass, m = 45 g

The temperature changes from 10°C to 30°C.

The specific heat is 0.5 J/g°C

We need to find heat required to raise the temperature. The formula that is used to find it is given by :

[tex]Q=mc\Delta T\\\\Q=45\times 0.5\times (30-10)\\\\Q=450\ J[/tex]

So, the required heat is 450 J. Hence, the correct option is (c).

The volume of Carbon dioxide : 29.12 L

Given

CH4 (g) + 202(g) → CO2(g) + 2H2O(g)

Oxygen volume = 63.3 L

Methane volume = 29.2 L

The volume of Carbon dioxide

Solution

1 mol gas at STP = 22.4 L

mol methane :

[tex]\tt \dfrac{29.2}{22.4}=1.3[/tex]

mol oxygen :

[tex]\tt \dfrac{63.3}{22.4}=2.83[/tex]

limiting reactant : CH₄(smaller ratio:mol/reaction coefficient)

So mol CO₂ based on CH₄

From equation, CO₂ : CH₄ = 1 : 1, so mol CO₂ = 1.3

The volume =

[tex]\tt 1.3\times 22.4=29.12~L[/tex]

The volume of carbon dioxide is produced in the reaction is 29.12 L

We know that

1 mol gas at STP = 22.4 L

So,

The mol methane is

[tex]= 29.2 \div 22.4\\\\= 1.3[/tex]

Now

The  mol oxygen is

[tex]= 63.3 \div 22.4\\\\= 2.83[/tex]

Now the volume is

[tex]= 22.4 \times 1.3[/tex]

= 29.12 L

Answer:

The concentration is 50%

Explanation:

Mass-Volume concentration is molarity (M) times 100% or [tex]\frac{Gsolute}{Lsoln}[/tex] * 100%

For this problem, we need to convert from milligrams to grams and milliliters to liters in order to plug the values into the equation and solve for the concentration.

So, 250 mg = 0.025g (there are 1000 mg in 1 g)

And 500ml = 0.05 L  (there are 1000 ml in 1 L)

Now we can solve for the concentration

[tex]\frac{0.025 g}{0.05 L}[/tex] [tex]* 100[/tex] %=  0.5 [tex]* 100[/tex] % = 50% of Tylenol concentration
