Answer:
V = 15.9512 dm³
Explanation:
Given data:
Pressure = P = 1.37 atm
Temperature = T= 315 K
Number of moles of nitrogen= n = 0.845 mol
Volume = V = ?
Formula:
PV = nRT
Now we will put the values in equation.
V = nRT/ P
V = ( 0.845 mol× 0.0821 dm³.atm.K⁻¹.mol⁻¹ × 315 K) / 1.37 atm
V = 21.853 dm³. atm/ 1.37 atm
V = 15.9512 dm³
Answer:
106.95 lb of CO2
Explanation:
Equation of reaction:
2C8H18 + 25O2 = 8CO2 + 18H2O
Mass of C8H18 = density × volume = 0.692×12×3.785×1000 = 31430.64 g
From the equation of reaction above,
2 moles of C8H18 (228 g) produced 8 moles of CO2 (352 g)
31430.64 g of C8H18 will produce 31430.6×352/228 = 48524.50 g of CO2 = 48524.50/1000 = 48.52450 kg of CO2 = 48.52450×2.204 = 106.95 lb of CO2
Answer:
Explanation:
(a)The first liquid phase temperature required at 183°C
(b)By drawing a tie line and intersection with the liquidus line, the composition of the first liquid deduced is
61.8wt% of sand
38.2wt% of Pb
(c)By studying the diagram, phase diagram is on liquidus line, then
The complete melting point temperature of alloy is 260°C
(d)If a tie line is drawn it is deduced that thecomposition of the last solid remaining prior to complete melting is 13wt% of Sn
The temperature when ice melts is 32 degrees Fahrenheit.
The force that holds protons and neutrons together is too strong to overcome.
<h3>Explanation</h3>
Consider the location of the particles in an atom.
- Electrons are found outside the nucleus.
- Protons and neutrons are found within the nucleus.
Protons carry positive charges and repel each other. The nucleus will break apart without the strong force that holds the protons and neutrons together. This force is much stronger than the attraction between the nucleus and the electrons. X-rays are energetic enough for removing electrons from an atom. However, you'll need a collider to remove protons from a stable nucleus. You could well have ionized the atom with all that energy.
Also, changing the number of protons per nucleus will convert the halogen atom to an atom of a different element. Rather than making the halogen negative, removing a proton will convert the halogen atom to the negative ion of a different element.
