Answer:
Explanation:
The names Px, Py and Pz, indicate the orientation of the orbital in space. The key difference between Px Py and Pz orbitals is that Px orbital has two lobes oriented along the x-axis and Py orbital has two lobes oriented along the y-axis whereas Pz orbital has two lobes oriented along the z-axis.
Answer:
c.
Explanation:
One of the main differences between an atom and an element is that an atom can be combined but an element cannot be combined. There are many combinations of atoms that make up different gases, liquids, and solids each with a unique makup. For example, water is made up of two hydrogen atoms and one oxygen atom (H20). Elements are made up of only the same type of atom. For example, the element Hydrogen can only contain hydrogen atoms, while the element Carbon can only contain carbon atoms.
Answer:
The final temperature of the iron is 95.86 °C
Explanation:
To solve the question we must first find out the specific heat of iron which is 0.450 J/g°C
Then we list out the known variables
Initialtemperature = 38 °C
Applied heat = 2213 joules
Mass of sample = 85 g
Therefore, the required formula relating the final temperature of the iron to the known variables is
ΔH = m·C·Δθ where ΔH = applied heat, m = mass, C = specific heat capacity
plugging in the values we have
2213 J = 85 g×0.450 J/g° C× (T₂ - 38 °C), where T₂ = The final temperature of the iron
2213 J - 1453.5 J = 38.25 × T₂ or T₂ = 95.86 °C
The final temperature of the iron is 95.86 °C
