Answer: i beleive it is fixation in edge 2020
Explanation:
Answer:
Basic or alkaline
Explanation:
ph 7 is neutral
below 7 is acidic
above 7 is basic or alkaline
P*V=n*R*T where p is the pressure, v the volume in L, n the quantity in moles, R a standard number that should be given and T the temperature in Kelvin
R=8.32 (usually)
T(in K)=273+T(in Celsius) so T=296K
P*V=n*R*T
P=n*R*T/V
P=0.4*8.32*296/0.2
Answer:
B. They bond identical atoms together
Explanation:
Metallic Bond: This is the bond that exists among the atoms of the metal. This is a type of electrostatic attraction between conduction electrons of metallic atom and their positively charged metal ions.
<em>(figure attached)</em>
Example:
Copper is a metallic element and its atoms consist of metallic bond among their selves.
Options A, B, D are not correct as all states for a kind of ionic bond formation.
Ionic bond:
It form by the complete transfer of electron from one atom to other
It is formed among two atoms of different electronegativities.
Also metals are electro-positive and non -metals are electro-negative so they form ionic bond.
Example is NaCl where sodium is a metal and Chloride is non-metal and they from ionic bond.
I think it would be these three answers ionic , covalent , and polar covalent
