The resulting pressure is 3.093 atm
<u><em>calculation</em></u>
The resulting pressure is calculated using the combined gas equation
That is P₁V₁/T₁ =P₂V₂/T₂ where,
P₁=0.956 atm
V₁=4.95 L
T₁=22.8 c in to kelvin= 22.8 +273 =295.8 k
P₂=? atm
V₂=1.75 L
T₂=65.3 c into kelvin = 65.3 +273 =338.3 K
make P₂ the subject of the formula by multiplying both side of the formula by T₂/V₂
P₂ =T₂P₁V₁ / V₂T₁
P₂ = [(338.3 k x 0.956 atm x 4.95 L) / ( 1.75 L x 295.8 K)] =3.093 atm
Answer:
Image
Explanation:
An electrolytic solution is a solution that has the ability of conducting electricity. Electrolytic solutions contain ions in which it conducts electricity from those ions. Ions are charged atoms. This solution (refer to image) has ions, as represented by the + and - symbols.
Answer:
1. Alpha particles consist of two protons and two neutrons.
Explanation:
Alpha particles are generally produced in the process of alpha decay, a radio active decay in which an atom loses an helium atom.
AN alpha particle is identical to the helium particle. The helium particle has mass number of 4 and atomic number of 2. This means;
Number of protons = 2
Number of neutrons = Mass Number - Atomic Number = 2
The correct option is option 1.
Answer:
The heat capacity for the sample is 0.913 J/°C
Explanation:
This is the formula for heat capacity that help us to solve this:
Q / (Final T° - Initial T°) = c . m
where m is mass and c, the specific heat of the substance
27.4 J / (80°C - 50°C) = c . 6.2 g
[27.4 J / (80°C - 50°C)] / 6.2 g = c
27.4 J / 30°C . 1/6.2g = c
0.147 J/g°C = c
Therefore, the heat capacity is 0.913 J/°C
