Answer:

The periodic table is a table displaying each element and information about the elements, for example atomic number and chemical properties. This is necessary because without it it would be very hard to find information on the elements.

A balloon filled with air has a volume of 4.24 liters at 23.00°C. If the balloon is cooled at constant pressure to 5.00°C, what
Ierofanga [76]

Answer:

The new volume will be

0.7 L

Explanation:

This is an example of Charles' law, sometimes called the temperature-volume law. It states that the volume of a gas is directly proportional to the Kelvin temperature, while pressure and amount are held constant.

A student sets up two reactions. reaction 1 uses 0.130 mol/l of reactant, and reaction 2 uses 0.440 mol/l of reactant. how many
Furkat [3]

<u>Given:</u>

Concentration of reactant used in reaction 1 = 0.130 mol/L

Concentration of reactant used in reaction 2 = 0.440 mol/L

<u>To determine:</u>

the rate of reaction 2 wrt to 1

<u>Explanation:</u>

Let the reaction be represented as:

Reactant → Product

Rate of reaction is:

[Rate] = k[reactant]

where k = rate constant

[reactant] = reactant concentration

for reactions 1 and 2 the rates are given as:

[Rate]₁ = k[reactant]₁=k[0.130] -------(1)

[Rate]₂= k[reactant]₂=k[0.440]--------(2)

2 ÷ 1

[Rate]₂/[Rate]₁ = 3.38

[Rate]₂ = 3.38[Rate]₁

Ans: Thus, reaction(2) is nearly 3 times faster than reaction(1)
