How many moles are I 24.0x10^18 molecules NaOH?
Answer:
[tex] \huge 3.986 \times { 10}^{ - 5} \: \: mol \\ [/tex]
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have

all of the following are properties of ionic compounds except:
A. Ionic compounds have low melting points,
B. Ionic compounds have high boiling points
C. Ionic compounds conduct electricity when dissolved in water
D. Ionic compounds are solid at room temperature
Answer:
A
Explanation:
They have generally high melting point compared to covalent compounds because they are formed by electrostatic force of attraction between two opposite charge is not easy to melt them in low melting point.
Ionic compounds have high melting and boiling points. Therefore, option A is not a property of ionic compound. Hence, option A is the correct answer.
Ionic compounds are neutral compounds. Ionic compounds are formed from cations and anions. Positively charged ion (cation) and negatively charged ion (anion) are held together with strong ionic bond. Some main properties of ionic compounds are,
High melting point and boiling pointsHave definite size and shapeConduct electricity in molten statesoluble in water and not soluble in organic solventsThus, we can conclude ionic compounds have high melting and boiling points. Hence, option A is the correct answer.

Elisa feels tired because she has a condition that affects whether the right molecules are getting to her cells. If her body were functioning correctly, this is what would happen with oxygen:
Answer:
It would be working properly and providing her energy for her daily activities.
Explanation:
Hello!
In this case, since her oxygen is actually working properly, it is going to be travelling throughout her entire body (via blood) and therefore carbon dioxide would be released as the exhalation product due to cellular respiration carried out in the alveoli which provides energy for her daily activities.
However, the intrusion of different molecules to oxygen into her cells may affect the rate at which cellular respiration is carried out and therefore she may feel tired because such process provides energy to the body.

(Numerical problems) A car is running with the velocity of 72km/h. What will be it's velocity after 5s if it's acceleration is -2m/s square
The car's velocity after 5s : 10 m/s
Further explanationGiven
velocity=v=72 km/h=20 m/s
time=t = 5 s
acceleration=a = -2 m/s²
Required
velocity after 5s
Solution
Straight motion changes with constant acceleration
[tex]\tt v_f=v_i+at[/tex]
vf=final velocity
vi = initial velocity
Input the value :
[tex]\tt v_f=20+(-2).5\\\\v_f=20-10\\\\v_f=10~m/s[/tex]
The car is decelerating (acceleration is negative) so that its speed decreases
Answer:
The Velocity after 5s if its acceleration is -2m/s is 10 m / s.
Explanation:
The motion equation is given by v = u + a x t.
Initial speed (u) is equal to 72 km/h.
Acceleration (a) equals 2 m/s2.
Time (t) = 5s.
Changing the initial velocity's direction from km/h to m/s:
1 km/hr is equal to 1000 m/3600 s/5/18 m/s.
velocity (u) is equal to 72 x (5 / 18) m/s, or 20 m/s.
The motion equation can be used to calculate final velocity.
To change values in the equation of motion, do the following:
Final Velocity (v) = u + a x t
v = u + a x t
v = 20 m/s + (-2 x 5) m/s
v = (20 - 10)m/s v = 10 m/s
As a result, the car's speed after 5 seconds will be 10 m/s.

calculate the equivalent weight of acid on the basis of given reaction. NaoH + H2So4 gives NaHSo4 + H20.
Answer:
98
Explanation:
Based on the reaction:
NaOH + H2SO4 → NaHSO4 + H2O
Where 1 mole of the base (NaOH) reacts per mole of the acid (H2SO4)
The formula of equivalent weight is:
Equivalent weight = Molecular mass / Number of equivalent moles
Where Molecular mass of sulfuric acid is 98g/mol
And number of equivalent moles = 1 -Because 1 mole of acid reacts per mole of base
Equivalent weight is:

Answer:
2.75 * 10^-5 m
Explanation:
The energy of the absorbed photon = ΔE
ΔE = - Ry (1/n^2 final - 1/n^2initial)
Given that Ry = 2.18 *10^-18 J
nfinal = 9
ninitial =8
ΔE = - 2.18 *10^-18 (1/9^2- 1/8^2)
ΔE = - 2.18 *10^-18 (0.0123 - 0.0156)
ΔE = 7.194 * 10^-21 J
But
ΔE =hc/λ
h = 6.6 *10^-34Js
c= 3 * 10^8 ms-1
λ= the unknown
λ= hc/ΔE
λ= 6.6 *10^-34 * 3 * 10^8/ 7.194 * 10^-21
λ= 2.75 * 10^-5 m

Mass of an empty 50 litres cylinder is 4.8kg. the cylinder is filled with 60atm nitrogen gas. molecular mass of nitrogen is 28. what is the new mass of cylinder
Answer:
8.235 kg
Explanation:
Mass of the cylinder = 4.8 kg
The capacity (volume) of the cylinder = 50 liters
As 1 m^3 = 1000 liters
So, the volume of the cylinder, v= 0.05 m^3
The volume of filled nitrogen, v= 0.05 m^3
Pressure of filled nitrogen, p = 60 atm = 60\times 101325 Pa
Assuming that the nitrogen gas is at room temperature which is 25-degree centigrade,
So, the temperature of nitrogen gas, T=273+25= 298 K
By using the ideal gas equation, pv=nRT
Where n is the number of moles, R is the universal gas constant, R = 8.314 J/mol·K
Putting all the values in the ideal gas equation, we have
(60 x 101325)0.05 = n (8.314) x (298)
n= (60 x 101325 x 0.05)/(8.314 x 298)
n=122.69 moles
As the molar mass of nitrogen is 28, so the total mass of the nitrogen in the cylinder, m= 122.69 x 28 = 3435.32 grams = 3.435 kg.
Hence, the new mass of the cylinder = 4.8+3.435=8.235 kg

no
potassium bromide lead(II) nitrate
yes
no
ammonium bromide sodium hydroxide
yes
no
Answer:
1) No, 2) Yes, 3) Yes
Explanation:
Refer to solubility rules to understand if a precipitate occurs between a mix of solutions.
Two solutions form a precipitate if they react to yield an insoluble product.
Let us now consider each of the reacting species one after the other.
In the first case;
Zn(NO3)2(aq) + FeI2(aq) ----> ZnI2(aq) + Fe(NO3)2(aq)
The two products of the reaction are soluble so no precipitate is formed.
In the second case;
2KBr(aq) + Pb(NO3)2(aq) ------> 2KNO3(aq) + PbBr2(s)
An insoluble product PbBr2 is formed hence a precipitate is formed.
In the third case;
NH4Br(aq) + NaOH(aq) -------> NH4OH(aq) + NaBr(aq)
No insoluble product is formed so the there is no precipitate.
