Which atom?
Atomic mass - proton
Explanation:
Also, the water molecules are not changed when sugar is dissolved in water to form a sugar solution. We can easily get back the sugar by evaporation of water from the sugar solution. The evaporated water can then be condensed to recover the water also. Hence, it is a physical change and not a chemical change.
Ida - Ida a.k.a 243 Ida is an asteroid in the Koronis family of the asteroid belt.
Ceres - Ceres a.k.a Dwarf Planet is the largest object in the asteroid belt that lies between the orbit of Mars and Jupiter.
Gaspra - Gaspra a.k.a 951 Gaspra is an S-type asteroid that orbits very close to the inner edge of the asteroid belt.
Answer:
Explanation:
The moving part won't move on its own there's a force but the force isn't enough for something like a bike chain it need grease to move smoothly or else it will just be super stuck or slow.
Answer:
3428.58 °C
Explanation:
We'll begin by converting 300 KPa to atm. This can be obtained as follow:
101.325 KPa = 1 atm
Therefore,
300 KPa = 300 KPa × 1 atm / 101.325 KPa
300 KPa = 2.96 atm
Next, we shall determine the temperature. This can be obtained as follow:
Number of mole (n) = 0.24 mole
Volume (V) = 25 L
Pressure (P) = 2.96 atm
Gas constant (R) = 0.0821 atm.L/Kmol
Temperature (T) =?
PV = nRT
2.96 × 25 = 0.24 × 0.0821 × T
74 = 0.24 × 0.0821 × T
Divide both side by 0.25 × 0.0821
T = 74 / (0.24 × 0.0821)
T = 3755.58 K
Finally, we shall convert 3755.58 K to °C. This can be obtained as followb:
T(°C) = T(K) – 273
T(K) = 3755.58 K
T(°C) = 3755.58 – 273
T(°C) = 3428.58 °C
Thus, the temperature at which the gas was collected is 3428.58 °C
