Using the combined gas law, where PV/T = constant, we first solve for PV/T for the initial conditions: (4.50 atm)(36.0 mL)/(10.0 + 273.15 K) = 0.57213.
Remember to use absolute temperature.
For the final conditions: (3.50 atm)(85.0 mL)/T = 297.5/T
Since these must equal, 0.57213 = 297.5/T
T = 519.98 K
Subtracting 273.15 gives 246.83 degC.
Answer:
10 kilowatts or 10,000 kw
Explanation:
Power = Force × Velocity
Given that:
Velocity of car is 50 m/s
The force is 200N
The power would be:
P = 200 × 50
P = 10,000 W
Notice that it only reaches watts because of the unit of the velocity is m/s. Standard unit to make Kw is km.
Since:
1 kw = 1000 w
10 kw = 10000 w

C. losing one electron
Explanation:
It is because the potassium atom electronic configuration is 2,8,8,1 where by if it loses one electron it becomes stable
Ch3sh is polar because it has polar bonds & the net dipole is nonzero
Answer:
It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.
Explanation:
Marble can be otherwise called metamorphic rock which is formed as a result of heat application on limestone and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.
