B, the opposing forces are the same, thus, the ball doesn't move back or forward.
Well, I think it's mainly for photosynthesis and gas exchange. A leaf is normally flat, light, and thin, so that the sunlight can get to the chloroplasts in the cells.
M = 10.0 Kg
acceleration of gravity = 9.8 m/s²
F = M * a
F = 10.0 * 9.8
F = 98 newtons.
hope this helps!.
The right answer is physical change.
In the general sense, dissolution is the action of dissolving something, that is to say, of decomposing it by the separation of its parts.
In chemistry, dissolution is an intimate mixture of two bodies, at least one of which is liquid.
Eg: the dissolution of sugar in the water, the sugar will pass from the solid and dry state to the dissolved state so there is a physical change. The sugar is going to be surrounded by water molecules and form hydrogen bonds, so it can be a chemical change.
Answer:
45830.4 moles
Explanation:
Ideal gas law is the hypothetical equation in which the pressure, volume, and temperature of the gas are directly related. It can be denoted as:
PV = nRT
The ideal gas law is:
PV = nRT
where,
P = Pressure
V = Volume
R = Gas constant
T =Temperature
n = moles
Given:
Moles in container = 1.95
Temperture = 294.85 K
Pressure = 3.75 atm
Volume =?
Substituting the values:
V = nRT/P
V = 1.95 × 0.082 × 294 / 3.75
Volume = 12.5 L
Now, the condition when changed, such that temperature is 301.25 K, pressure is 0.998 atm, and Volume is 12.5 L, then moles will be equal to:
PV/RT = n
0.998 × 12.5 / 0.082 × 301.25 = n
n = 45830.4 moles
Therefore, 0.521 moles is still present in the container.
