Somebody help me please i'm tired of trying to solve this problem ༎ຶ‿༎ຶ​
Elenna [48]

Answer:

Q    Line     A

A: (a) 0 (b) 20

B: (b) 10 (c) 10

C: (c) 10 (d) 10

D: (d) 10 (e) 13

E: (e) 13 (f) 0

F: (f) 0 (g) 0

a: The velocity is whatever you need to see when you are specifically using a numberline so the answer for a is just 10

b: The velocity for this one is not as easy as the last one, its 7.

Explanation:

When you have a number line and your trying to find a numberline, you just have to subtract the smaller line to the largest number but if you are trying to find the velocity in beetween more than one thane you add the two biggest ones and subtract the smallest one and if you make a wrong move like add the biggest and smalles youll... still get the same answer so it doesnt matter really but its just easier to do the smallest one as the subtracting number just FYI. Happy spring break!

In titrating 0.20 M hydrochloric acid, HCl, with 0.20 M NaOH at 25°C, the solution at the equivalence point is
xxTIMURxx [149]

Answer:

c) 0.10M NaCl

Explanation:

<em>Options are:</em>

<em>a) 0.20M NaCl</em>

<em>b) Very acidic</em>

<em>c) 0.10M NaCl</em>

<em>d) 0.10M HCl + 0.20M NaOH</em>

<em>e) Slightly acidic.</em>

<em />

Based on the reaction:

NaOH + HCl → H₂O + NaCl

You can see than 1 mole of NaOH reacts per mole of HCl producing 1 mole of NaCl

Assuming 1L of 0.20M HCl reacts with 1L of NaOH, moles of both compounds are:

1L * 0.20mol/L = 0.20 moles reacts. That means moles of NaCl produced are 0.20moles in 2L. Molarity of NaCl is:

0.20mol / 2L = 0.10M NaCl

That means, right option is:

<h3>c) 0.10M NaCl</h3>

There are always attractive forces between a collection of atoms or molecules which may not be negligible as suggested by the ki
Harrizon [31]

Answer:

Negligible

Explanation:

According to the kinetic theory of gases, the degree of intermolecular interaction between gases is minimal and gas molecules tend to spread out and fill up the volume of the container.

If the attraction between gas molecules increases, then the volume of the gas decreases accordingly. This is because, gas molecules become highly attracted to each other.

This intermolecular attractive force may be so strong, such that the actual volume of the gas become negligible compared to the volume of the container.

What did Ernest Rutherford’s gold foil experiment demonstrate about atoms ?
Alchen [17]

Answer:

Their positive charge is located in the small nucleus

Explanation:

Ernest Rutherford performed the gold foil experiment in 1911 where he used alpha particles generated from a radioactive source to bombard a thin gold foil.

In his experiment, he observed that the bulk of the alpha particles passed through the gold foil, just a tiny fraction was deflected back. To explain his findings, Rutherford proposed that an atom is made of positively charged centre where nearly all the mass is concentrated called nucleus. Surrounding the nucleus is a large space containing electrons.
