ANS: density = 13.41 g/ml
Density (d) of a substance is the mass (m) occupied by it in a given volume (v).
Density = mass/volume
i.e. d = m/v
m = (d) v -----(1)
The given equation from the plot of weight vs volume is :
y = 13.41 x ----(2)
Based on equations (1) and (2) we can deduce that the density of the metal is 13.41 g/ml
Answer:
His speed was 2 m/s, and his velocity was 0. So it is B
Explanation:
took the test
Explanation:
Atomic number = number of electrons = 10
Mass number = number of electrons + number of neutrons = 10 + 14 = 24
Answer:
your whole body is with a higher temperature than normal. The reason you can't take your own temperature with your hand is because the hand is the same temperature as your head.You won't be able to detect a difference in temperature between them.
The oxidation number of V and Al in each ion is +3 and +4 respectively.
<h3>What is oxidation number in chemistry?</h3>
oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.
<h3 /><h3>Why is it called oxidation number?</h3>
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.
