Answer:
10 atoms
Explanation:
To find out the number of atoms: MULTIPLY all the SUBSCRIPTS in the molecule by the COEFFICIENT.
Answer:
Gas ⟶ liquid (condensation)
Explanation:
If the molecules are far apart, they are in the gas phase.
As the temperature drops, the molecules lose kinetic energy.
They can no longer escape the attractive forces between them and their neighbours, so they stick together and form a liquid.
The most likely change of state is gas ⟶ liquid (condensation).
Answer:
0.013 mole
Explanation:
Step 1:
Data obtained from the question. This includes:
Volume (V) = 250 mL
Pressure (P) = 1.3 atm
Temperature (T) = 33°C
Number of mole of (n) =?
Step 2:
Conversion to appropriate units.
The volume and the temperature given in the question must be converted to their appropriate unit in order to obtain the answer to the question in the right unit.
For volume:
We must, convert mL to L
1000 mL = 1 L
Therefore, 250 mL = 250/1000 = 0.25 L
For temperature:
We, must convert °C to K.
K = °C + 273
K = 33°C + 273
K = 306K
Step 3:
Determination of the number of mole of CO2.
Applying the ideal gas equation:
PV = nRT
The number of mole of CO2 can be obtained as follow:
V = 0.25 L
P = 1.3 atm
T = 306K
R (gas constant) = 0.082atm.L/Kmol
Number of mole of (n) =?
PV = nRT
1.3 x 0.25 = n x 0.082 x 306
Divide both side by 0.082 x 306
n = (1.3 x 0.25) /(0.082 x 306)
n = 0.013 mole
Atoms with neutrons, protons, and electrons. Only the neutron has no electrical charge; protons and electrons are the other particles that are electrically charged.
<h3>What do you know about atoms? explain.</h3>
The smallest component of ordinary stuff that makes up a chemical element is an atom. Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma. Atoms are incredibly tiny, measuring typically 100 picometers across. Due to quantum effects, they are so small that it is impossible to predict their behavior with sufficient accuracy using classical physics, as would be the case, for example, if they were tennis balls.
Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus. Only the most prevalent type of hydrogen is neutron-free. The nucleus of an atom contains more than 99.94% of its mass. The electric charges of the protons are positive, those of the electrons are negative, and those of the neutrons are zero. The atom is electrically neutral if the number of protons and electrons is equal.
