Answer:
All substances can be characterized by their unique sets of physical and chemical properties. Properties that can be determined without changing the composition of a substance are referred to as physical properties. Characteristics such as melting point, boiling point, density, solubility, color, odor, etc.
Answer:
1) correct
2) incorrect
3) correct
4)incorrect
Explanation:
1) A Lewis acid is a substance that accepts a nonbonding pair of electrons.
A Bronsted-Lowry acid is a substance that donates a proton H⁺
Since the donation of a proton involves the acceptance of a pair of electrons, every Bronsted-Lowry acid is also a Lewis acid.
2)A Lewis acid not necessarily needs to have a proton to be donated.
3) Conjugated acids of weak bases are strong acids and conjugated acids of strong bases are weak acids.
4)K⁺ comes from a strong base, therefore is does not have an acidic behaviour.
Answer:
Dominant traits are traits that more likely to be transferred from a parent to an offspring so scientist use this term dominant.
Answer:
It will have more speed/more acceleration than or the ground.
Explanation:
It will lean twords the side that moves and for ex if the wagon has a level to pull a gap down the ball will go forward
True
As the shorter the bond, the stronger it is hence more energy will be required to overcome this bond
