An inflated balloon contains X air molecules.After some time the volume of the balloon is found to be the half at the same temperature and pressure when a few air molecules are expelled out. a)How many molecules will be there in the balloon now? b) Which is the gas law associated with this?
Answer:
See explanation
Explanation:
According to Avogadro's law, the volume of a given mass of gas is directly proportional to the number of molecules of gas present at constant temperature and pressure.
Hence; V1/n1 = V2/n2
The implication of this is, if there were X molecules present and the volume of the balloon is halved, the number of molecules of gas present is also halved. So, we now have X/2 number of gas molecules present in the balloon.
This is in accordance with the statement of Avogadro's law.

What must happen to the atoms before they are accelerated in the mass spectrometer?
Answer:
Atoms and molecules can be deflected by magnetic fields - provided the atom or molecule is first turned into an ion. Electrically charged particles are affected by a magnetic field although electrically neutral ones aren't. The atom or molecule is ionised by knocking one or more electrons off to give a positive ion.
Explanation:
Please Mark me brainliest
The atom must first be ionized.
The mass spectrometer is an important analytical tool in chemistry. It is used to identify atoms and molecules.
However, the atom or molecule to be analysed must first be converted into an ion.
This happens when the instrument imparts an electrical charge to the molecule or atom then the electrically charged ions are read as electrical current. The ion is accelerated towards a detector which analyses the deflected ions.

Why do we not see a solar and lunar eclipse every lunar cycle?
Answer:
Explanation: We don't see lunar eclipses every cycle because the Moon's orbit is tilted five degrees from Earth's orbit around the Sun. And when an eclipse occurs the earth passes directly between Sun and Moon.

2500 cal of heat are absorbed by 150 grams of water that is initially at 23°C, what is the final temperature of the water?
Answer:
H=MC∆T
Heat = Heat absorbed or given off
M=Mass
C=Specific Heat Capacity of substance (Water in thus case). It has a Specific Heat capacity of 4200J/kg.k
∆T= Temp Change (T2-T1)
I'll solve with My Heat in Joules.
The heat is given in Calorie
1Cal = 4.186J
2500cal = 10,465J.
∆T= H/MC
=10465/0.15(4200)
=16.6°C
∆T=16.6
T2 - T1 = 16.6
T2 = 16.6+T1
T2 = 16.6 + 23
T2 = 39.6
Approx. 40°C
Which gas would effuse more slowly:
Xe
CO2
CH4
N2
N2 should be the gas to effuse more slowly
Inside a car that was at STP, a 1.33 L bottle warms up to 130 C. If the volume of the bottle remains constant, what is the pressure, in atm, inside the hot water bottle?
Answer:
[tex]P_2=1.48atm[/tex]
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to infer this problem is about the application of the Gay-Lussac's gas law to relate the initial and final pressure and temperature as shown below:
[tex]\frac{P_2}{T_2} =\frac{P_1}{T_1\\ }[/tex]
Thus, solving for the final pressure, P2, and using the temperatures in Kelvins, we obtain:
[tex]P_2 =\frac{P_1T_2}{T_1 }\\\\P_2 =\frac{1atm*403.15K}{273.15K}\\\\P_2=1.48atm[/tex]

In the backyard calorimetry lab I had 189.5 grams of water in my Batman thermos. The water started out at a
temperature of 16.4 °C. After a few minutes the water cooled to 8.9°C. How much thermal energy did the
water use to melt the ice cube?
Answer:
Q = 5949.35 J
Explanation:
Given that,
The mass of water, m = 189.5 grams
Initial temperature, T = 16.4 °C
Final temperature, T' = 8.9°C
We need to find the thermal energy the water use to melt the ice cube. The thermal energy is given by :
[tex]Q=mc\Delta T[/tex]
Where
c is the specific heat of the water, c = 4.186 joule/gram °C
So,
[tex]Q=189.5\times 4.186 \times (8.9-16.4)\\Q=-5949.35\ J[/tex]
So, the required amount heat is equal to 5949.35 J.

The Ksp of SrSO4 is 3.2 × 10–7. What is the equilibrium concentration of sulfate ion in a 1.0-L solution of strontium sulfate to which 0.10 mol of Sr(CH3CO2)2 has been added?
Answer:
3.2x10⁻⁶M of sulfate ion can be added
Explanation:
The solubility of SrSO4 is:
SrSO4(s) → Sr²⁺(aq) + SO₄²⁻(aq)
Where Ksp is defined as:
Ksp = 3.2x10⁻⁷ = [Sr²⁺] [SO₄²⁻]
The concentration of Sr is:
0.10mol / 1L = 0.10M = [Sr²⁺]
Replacing in Ksp:
3.2x10⁻⁷ = [0.10M] [SO₄²⁻]
[SO₄²⁻] = 3.2x10⁻⁶M of sulfate ion can be added

Answer:
7.65 moles of silver are produced
Explanation:
Zinc, Zn, reacts with silver nitrate, AgNO3, as follows:
Zn + 2AgNO3 → Zn(NO3)2 + 2Ag
Where 1 mole of Zn reacts with an excess of AgNO3 to produce 2 moles of Ag
To solve this question we must convert the mass of Zn to moles and, using the chemical equation, we can find the moles of Ag as follows:
Moles Zn (Molar mass: 65.38g/mol):
250g Zn * (1mol / 65.38g) = 3.824 moles Zn
Moles Ag:
3.824 moles Zn * (2mol Ag / 1mol Zn) =
