Magnesium bromide= MgBr2
Potassium chloride= KCl
I would say d but I’m not sure

<u>
CF4 </u>
is the one which is covalent compound</h2><h2 /><h2 /><h2>explanation</h2>
CF4 compound is formed between two non metal that is between carbon and fluorine and a covalent compound is formed when two non metal combine by sharing. electrons. CF4 has a strong bond strength due to the nature of carbon- fluorine bond.
Answer:
0.008 moles of gas are present
Explanation:
Given data:
Volume of gas = 1.75 L
Number of moles = ?
Temperature of gas = 58°C
Pressure of gas = 12.5 KPa
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
58+273 = 331 K
Pressure = 12.5/101 = 0.12 atm
by putting values in formula:
0.12 atm× 1.75 L = n× 0.0821 atm.L/ mol.K ×331 K
0.21 atm.L = n× 27.17atm.L/ mol
n = 0.21 atm.L /27.17atm.L/ mol
n = 0.008 mol
Answer:
A chemical bond formed when two atoms share two pairs of electrons is a<em> </em><em>d</em><em>o</em><em>u</em><em>b</em><em>l</em><em>e</em><em> </em>bond; it is best described as a <em>c</em><em>o</em><em>v</em><em>a</em><em>l</em><em>e</em><em>n</em><em>t</em><em> </em><em>b</em><em>o</em><em>n</em><em>d</em><em>.</em>
Explanation:
A chemical bond in which two pairs of electrons are shared has to be defined as covalent since ionic bonds don't involve electron sharing. They consist only of electrostatic attraction between ions.
