Acetic acid (HC2H3O2) is an important ingredient of vinegar. A sample of 50.0 mL of a commercial vinegar is titrated against a 1

butalik [34]

Answer:

The concentration of acetic acid present in the vinegar is 0.113M

Explanation:

1. As the titration occurs between an acid and a base is called neutralization. The balanced chemical reaction between the acetic acid and the NaOH is:

$NaOH+HC_{2}H_{3}O_{2}=NaC_{2}H_{3}O_{2}+H_{2}O$

2. Calculate the moles of NaOH used, taking in account the concentration of NaOH 1.00M:

$5.65mL*\frac{1.00molesNaOH}{1000mLNaOH}=0.00565molesNaOH$

3. Calculate the number of moles of acetic acid neutralized using stoichiometry:

$0.00565molesNaOH*\frac{1molHC_{2}H_{3}O_{2}}{1molNaOH}=0.00565molesHC_{2}H_{3}O_{2}$

4. Calculate the concentration of acetic acid present in the vinegar:

$\frac{0.00565molesHC_{2}H_{3}O_{2}}{50.0mLvinegar}*\frac{1000mLvinegar}{1Lvinegar}=0.113M$

The chart show the masses and velocities of two colliding objects that stick together after a collision.

finlep [7]

Answer:

1,500 kg.m/s

Explanation:

First, arrange the information in a table:

Object Mass (kg) Velocity (m/s)

A 200 15

B 150 - 10

After the collision, the two objects are stick together, thus you talk aobut one object and one momentum.

According to the law of convervation of momentum, the momentum after the collision is equal to the momentum before the collision.

Momentum before the collision, P₁:

$P_1=m_{A,1}\times v_{A,1}+m_{B,1}\times v_{B,1}$

$P_1=200kg\times 15m/s+150kg\times (-10m/s)\\\\ P_1=3000kg.m/s-1500kg.m/s=1500kg.m/s$

Momentum after the collision:

As stated, it es equal to the momentum before the collision: 1,500 kg . m/s
