Answer:

**Answer:**

Rate of reaction will be half of it's initial value

**Explanation:**

**For the given reaction, the rate law is -**

**Where k is rate constant, [1-iodo-2-methylbutane] is concentration of 1-iodo-2-methylbutane and is concentration of **

Here nucleophile is the ion

Initiallly,

When concentration of is halved then-

So rate of reaction will be half of it's initial value

In both industry and research there are often times when one particular component of a mixture needs to be separated from a solution. Maybe it is a rare metal that is dissolved in a mixture of minerals. Maybe it is a particular protein from lysed plant cells. If the desired component is volatile, distillation could be used. But if the goal is to separate ions in solution, fractional precipitation is preferred.a. Trueb. False

Blood samples for research or medical tests sometimes have heparin added. Why is this done?

**Answer: 75 liters of in liters would be required if 15.0 L of propane burns, assuming that all of the gases are under the same conditions.**

**Explanation:**

According to avogadro's law, 1 mole of every substance occupies 22.4 Lat STP and contains avogadro's number of particles.

To calculate the number of moles, we use the equation:

According to stoichiometry:

1 mole of propane combines with = 5 moles of oxygen

Thus 0.67 moles of propane combine with =

Volume of

**Thus 75 liters of in liters would be required if 15.0 L of propane burns, assuming that all of the gases are under the same conditions.**

**Answer:**

s = 22.352 m/s

**Explanation:**

**Given data:**

Time taken = 0.5 hours

Distance cover = 25 miles

Car speed = ?

**Solution:**

First of all we will convert the units.

1 hour = 3600 sec

0.5 hr ×3600 sec / 1hr = 1800 sec

**miles to meter:**

25 mi × 1609 m/ 1 mi = 40233.6 m

**Formula:**

s = d/t

s = speed

d = distance

t = time

Now we will put the values in formula.

s = 40233.6 m / 1800 sec

s = 22.352 m/s

The speed of the car, calculated by dividing the **distance travelled **(25 miles) by the time taken (0.5 hours), is 50 miles per hour.

The subject of the question falls under **Mathematics**, specifically a section of it named rate, time, and distance problems. The problem is asking us to calculate the speed of a car which can be obtained by dividing the distance travelled by the time taken. Given that the distance travelled by the car is 25 miles and the time taken is 0.5 hours, we can calculate the speed as follows.

- Denote the Speed as
*S*, the distance as*D*, and the time as*T*. - Since Speed = Distance/Time, we substitute our values into this equation
- Therefore, Speed = 25 miles / 0.5 hour =
**50 miles/hour**

So, the speed of the car is 50 miles per hour.

**Answer:**

8.0 mol O₂

**Explanation:**

Let's consider the **complete combustion** reaction of C₉H₁₂.

C₉H₁₂ + 12 O₂ → 9 CO₂ + 6 H₂O

The **molar ratio of C₉H₁₂ to O₂** is 1:12. The moles of O₂ required to react with 0.67 moles of C₉H₁₂ are:

0.67 mol C₉H₁₂ × (12 mol O₂/1 mol C₉H₁₂) = 8.0 mol O₂

8.0 moles of O₂ are required to completely react with 0.67 moles of C₉H₁₂.

**Answer:**

To react with 0.67 moles C9H12 we need 8.04 moles of O2

**Explanation:**

Step 1: Data given

Number of moles C9H12 = 0.67 moles

Step 2: The balanced equation

C9H12 + 12O2 → 9CO2 + 6H2O

Step 3: Calculate moles of O2 required

For 1 mol C9H12 we need 12 moles of O2 to produce 9 moles of CO2 and 6 moles of H2O

For 0.67 moles of C9H12 we need 12 *0.67 = 8.04 moles of O2

To produce 9*0.67 = 6.03 moles of CO2 and 6*0.67 = 4.02 moles H2O

To react with 0.67 moles C9H12 we need 8.04 moles of O2

Answer:

A. 1 J=1kg•m^2/s^2

Explanation:

Energy refers to the capacity to do work. According to the International System of units (SI units), energy is measured in Joules.

Energy is represented by the force applied over a distance. Force is measured in Newton (N) and distance in metres (m). Hence, energy is Newton × metre (N.m)

Newton is derived from the SI units of mass (Kilograms), and acceleration (metres per seconds^2) i.e Kg.m/s^2, since Force = mass × acceleration.

Since; Energy = Newton × metres

If Newton = Kg.m/s^2 and metres = m

Energy (J) will therefore be; Kg.m/s^2 × m

1J = Kg.m^2/s^2
