Perhaps when they are trying to find the distance of an asteroid to the Earth to find out whether or not it is a hazard to Earth.
Answer: There are now 2.07 moles of gas in the flask.
Explanation:
P= Pressure of the gas = 697 mmHg = 0.92 atm (760 mmHg= 1 atm)
V= Volume of gas = volume of container = ?
n = number of moles = 1.9
T = Temperature of the gas = 21°C=(21+273)K= 294 K (0°C = 273 K)
R= Value of gas constant = 0.0821 Latm\K mol
When more gas is added to the flask. The new pressure is 775 mm Hg and the temperature is now 26 °C, but the volume remains same.Thus again using ideal gas equation to find number of moles.
P= Pressure of the gas = 775 mmHg = 1.02 atm (760 mmHg= 1 atm)
V= Volume of gas = volume of container = 49.8 L
n = number of moles = ?
T = Temperature of the gas = 26°C=(26+273)K= 299 K (0°C = 273 K)
R= Value of gas constant = 0.0821 Latm\K mol
Thus the now the container contains 2.07 moles.
Answer:
it is easier for them to have an octet of electrons(8e)
Each ion will: obtain the noble gas structure, each atom has high ionization energy
Explanation:
.
In this experiment, the experimental group is ice, the independent variable is sunlight while on the other hand, the dependent variable is block of ice.
<h3>What are dependent and independent variables?</h3>
Dependent variable is a type of variable in which a variable whose value depends on another variable while on the other hand, independent variable is a type of variable in which a variable whose value does not depends on another variable. Dependent variable is denoted by X whereas the independent variable is denoted by Y.
So we can conclude that In this experiment, the experimental group is ice, the independent variable is sunlight while on the other hand, the dependent variable is block of ice.
