Answer:

v = 46.5 m/s

Explanation:

Given data:

Mass of car = 1210 kg

Momentum of car = 56250 kg m/s

Velocity of car = ?

Solution:

Formula:

p = mv

p = momentum

m = mass

v = velocity

Now we will put values in formula:

56250 kg m/s  = 1210 kg × v

v = 56250 kg m/s / 1210 kg

v = 46.5 m/s

So a car having mass of 1210 kg with momentum 56250 kg m/s having 46.5 m/s velocity.

Calculate the percentrage of neutral form of aspirin that is present in the stomach ph 1.
Korolek [52]

Answer:

The 99.68% of the aspirin is present in the neutral form

Explanation:

Aspirin, Acetylsalicylic acid, is a weak acid with pKa = 3.5

Using Henderson-Hasselbalch equation:

pH = pKa + log [A⁻] / [HA]

<em>Where [A⁻] is the ionized form and HA the neutral form of the acid</em>

<em />

Replacing with a pH of stomach of 1.0:

1.0 = 3.5 + log [A⁻] / [HA]

-2.5 = log [A⁻] / [HA]

3.16x10⁻³ = [A⁻] / [HA] <em>(1)</em>

<em />

A 100% of aspirin is = [A⁻] + [HA]

100 = [A⁻] + [HA] <em>(2)</em>

<em></em>

Replacing (2) in (1)

3.16x10⁻³ = 100 - [HA] / [HA]

3.16x10⁻³[HA] = 100 - [HA]

1.00316 [HA] = 100

[HA] = 99.68%

When barium reacts with tellurium to form an ionic compound, each metal atom loses electron(s) and each nonmetal atom gains elec
Bess [88]

<u>Answer:</u> The ionic compound formed is baF_2 (barium fluoride)

<u>Explanation:</u>

Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.

Taking the metal as barium and non-metal as fluorine.

Barium is the 56th element of the periodic table having electronic configuration of [Xe]6s^2

This element will loose 2 electrons and will form Ba^{2+} ion

Fluorine is the 9th element of the periodic table having electronic configuration of [He]2s^22p^5

This element will gain 1 electron and will form F^{-} ion

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

Hence, the ionic compound formed is baF_2 (barium fluoride)

20 mL of a gas at 200K is heated until the new volume is 55 mL. What is the final temperature of the gas?
Lostsunrise [7]

Answer:

550 K

Explanation:

Given the following data;

Original Volume, V1 = 20mL

Original Temperature, T1 = 200K

New Temperature, V2 = 55mL

To find new temperature T2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

VT = K

\frac{V1}{T1} = \frac{V2}{T2}

Making T2 the subject of formula, we have;

T_{2} = \frac{V2}{V1} * T_{1}\\

Substituting into the equation;

T_{2} = \frac{55}{20} * 200\\T_{2} = \frac{11000}{20}\\T_{2} = 550K

Therefore, the new temperature is 550K.
