Sam would have to purchase 42 cans of dog food each week.
Determine what the question is asking. Write down the relevant information in simple statements. Assign symbols to unknown values that need to be found. Determine how the statements relate to each other mathematically.
To find the answer we can set up an equation : 3 (x) (d)
x = number of cans each dog eats
d = the number of days in a week.
Thus,
Number of Cans to purchase = 3 (2) (7)=42
Therefore, Sam would have to purchase 42 cans of dog food each week.

Answer:
The solid will sublime into a gas
Explanation:
See the phase diagram attached (the diagram is not an exact representation of this case, it is only illustrative). You starts at point A, that is, a point below triple point pressure (220 mmHg is lower than 225 mmHg) and to the left of triple point temperature (-35 °C is lower than -24.5 °C). Then, you move to point B, which is at the same pressure at A but its temperature is to the right of triple point temperature (0°C is greater than -24.5 °C).
(2) H−Cl
(3) I−Br
(4) I−Cl
Among the presented bonds, the most polar is H-Cl.
Polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment.
The higher the difference in electronegativity, the more polar the bond.
We will calculate the difference in electronegativity for each bond.
ΔEN = |EN(H)-EN(Br)| = |2.2-3.0| = 0.8
ΔEN = |EN(H)-EN(Cl)| = |2.2-3.2| = 1.0
ΔEN = |EN(I)-EN(Br)| = |2.7-3.0| = 0.3
ΔEN = |EN(I)-EN(Cl)| = |2.7-3.2| = 0.5
Among the presented bonds, the most polar is H-Cl.
