Answer:
Spring summer fall.
Explanation:
As a general rule, if you're in the Northern Hemisphere, look towards the southern skies to see the galactic core. This can be southeast (Spring), due south (Summer), or southwest (Fall) depending on the time of year. As mentioned above, Sagittarius is found nearest the galactic core.
C. "A" mentions that the drug killed all of the bacteria that are resistant to the drug, and that doesn't make any sense. "B" claims that all bacteria are resistant to the drug. This is not true. "D" mentions that bacteria eat the drug, which doesn't happen.
Answer:
high melting and boiling points
Explanation:
Answer:
2408.1 °C
Explanation:
Given data:
Mass of oxygen = 1.70 g
Volume occupy = 9.75 L
Pressure of gas = 799 torr (799/760 = 1.1 atm)
Temperature = ?
Solution:
Formula:
PV = nRT
First of all we will determine the number of moles of oxygen.
Number of moles = mass/ molar mass
Number of moles = 1.70 g/ 32 g/mol
Number of moles = 0.05 mol
Now we will put the values.
R = general gas constant = 0.0821 atm.L/ mol.K
T = PV/nR
T = 1.1 atm× 9.75 L /0.05 mol ×0.0821 atm.L/ mol.K
T = 10.725 /0.004
T = 2681.25 K
kelvin to °C
2681.25 K - 273.15 = 2408.1 °C
