Answer:
-
Explanation:
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
Answer:
Non metals join to form covalent bond.
Explanation:
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.
Both atoms bonded through covalent bond.
In Cl₂ both chlorine atoms are bonded through the covalent bond.
large iguanas are affected by el nino temperatures
because algae do not grow as rapidly with el nino temperatures
survival rates for the larger iguanas drop
if they are bigger than 36 centimeters
the drop happens beginning with sizes around 40 centimeters
Answer: 6.48m/s
Explanation:
From the question given, we obtained the following:
M = 50 kg
Velocity =?
Momentum = 324 kg•m/s
Momentum = Mass x Velocity
Velocity = momentum /Mass
Velocity = 324 / 50
Velocity = 6.48m/s
