Neodymium is a chemical element with symbol Nd and atomic number 60.
Answer:
Volume = 44.96L
Explanation:
p = 427mmHg = 0.56atm
R = 0.08206
T 6°C = 279k
V = ?
n = 1.10 mol
using ideal gas equation
pv=nRT
0.56 x V = 1.10 x 0.08206 x 279
0.56 x V = 25.18
V = 25.18/0.56
V = 44.96L
Answer:
4.6 moles.
Explanation:
To find the amount of moles of Magnesium, you will need to use Avogadro's number to convert between the two units.
2.77×10^24 moles Mg * (1 mol Mg)/(6.02*10^23)) ≈ 0.46×10^1 moles which equals <u>4.6 moles.</u>
I think the correct answer among the choices listed above is option A. <span>Given a chemical reaction, methane (CH4) burns in oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). The chemical reaction is best represented as:
</span><span>CH4 + O2 ----> CO2 + H2O</span>
Use this equation:
q = mc∆T
q is the heat energy your trying to find out
m is the mass of water (150g)
c is the specific heat capacity of water (4.18)
∆T is the temperature change (96.3-38.8)
so just multiply m c and ∆T to find q in joules
