Stigma
Stamen so the last one is correct
The correct answer is letter A. We use the formula, <span>v=vo + at to get the answer.</span>
<span>
v=vo + at </span>
<span>v=0 + (9.8)(8) </span>
<span>v=78.4 </span>
<span>y=1/2(vo + v)t </span>
<span>y=1/2(78.4)(8) </span>
<span>y=1/2(627.2) </span>
<span>y=313.6m
</span>
The molar volume of a gas at STP occupies <u>22.4 L.</u>
Option D
<u>Explanation:</u>
To find the volume of 1 mole of a gas at STP, we use the Ideal Gas Law. It is the general gas equation which gives the relation to the measurable quantities to an ideal gas as below,
P (pressure) × V (volume) = n (number of moles) × R (the gas constant) × T (temperature in Kelvin)
STP = 1 atm of pressure and 273 K for temperature
P = 1 atm
V = ?
n = 1 mole
R = 0.0821 atm L/mol K
T = 273 K
Using the equation,
By substituting the above values, in the equation,
V = 22.38 L
Marble has the same mass but a different volume so its less dense
A covalent bond is a bond between two non-metal atoms in which electrons are SHARED between the two bonded atoms. An example of this would be, the C-H bonds that are present in the molecule Methane (
