Answer:
An oxidising agent oxidises something else. Oxidation is loss of electrons (OIL RIG). That means that an oxidising agent takes electrons from that other substance.
Explanation:
Answer:
Nitrogen and Argon
Explanation:
These gases are part of a class of "noble" gases because they don't react with anything.
Answer: The bond between boron and hydrogen in boron trihydride is covalent bond.
Explanation:
The type of bonding between the atoms forming a compound is determined by using the electronegativity difference between the atoms. According to the pauling's electronegativity rule:
- If
, then the bond is non-polar. - If
, then the bond will be covalent. - If
, then the bond will be ionic.
We are given:
Electronegativity for boron = 2.0
Electronegativity for hydrogen = 2.1

As,
is less than 1.7 and not equal to 0. Hence, the bond between boron and hydrogen is covalent bond.
First of all scientific evidence is anything that is gathered using the scientific method that supports a hypothesis can be considered. According to me, a good place to start evaluating is to look at whether the evidence was collected using good scientific principles.
Good luck :)
Answer:
Atom: The smallest particle of an element that has the properties of the element and can exist either alone or in combination.
Particle: One of the very small parts of matter (as a molecule, atom, or electron)
