Explanation:
the ice release energy which case water molecule to have least kinetic and potential energy change their confiscation for solid
Answer:
The volume of the gas is 0.015 m^3.
Explanation:
mass, m = 32 g
Temperature, T = 45 °C = 45 + 273 = 318 K
Pressure, P = 728 mm of hg = 0.728 x 13.6 x 1000 x 9.8 = 97027.84 Pa
Atomic mass = 4 x 12 + 10 x 1 = 58 g
Use the ideal gas equation
Let the volume is V.
P V = n R T
Answer:
so i never did this befor so i am sorry hope you get the answer
Explanation:
Answer is: 4)Mass
I really hope this helped you out!!!!
The testable question which will provide evidence that elements in the same group have similar properties is valency
<h3>What is the valency?</h3>
In essence, how many electrons are present in their outermost shell.
Valency and Groups in the periodic table, elements are arranged in order of their atomic numbers and hence, the periodic table is a systematic arrangement of elements in an array of vertical columns called Groups and horizontal arrays called Periods.
which of the following testable questions will provide evidence that elements in the same group have similar properties A. Valency B. Orbit C. Group D. Period
Since, the reactive capacities of elements is dependent on the number of electrons on its outermost shell, we can conclude on this note that, Elements in the same group have similar properties.
