Answer:
The basicity of HCOOH (otherwise known as formic acid) is 1
Explanation:
Answer:
A. The balloons will increase to twice their original volume.
Explanation:
Boyle's law states that the pressure exerted on a gas is inversely proportional to the volume occupied by the gas at constant temperature. That is:
P ∝ 1/V
P = k/V
PV = k (constant)
P = pressure, V = volume.
Let the initial pressure of the balloon be P, i.e. 
, initial volume be V, i.e. 
. The pressure is then halved, i.e. 
Therefore the balloon volume will increase to twice their original volume.
1- thé everyday use of kinematic basically the speed for something it’s the magnitude.
2-the speed of something in a certain direction
2a- They are both related by speed.
3-the capacity of a vehicle which gains speed in a short time
4-it’s an attraction of all matter (not sure on this one)
Answer:
a. because it is an element
Explanation:
its pure because it only has one type of atom, making it an element
The number following the name of the element is the number of subatomic particles inside the nucleus of the atom. This means that it is the mass number of the isotope. The average atomic mass of the element is the sum of the products of the percentage abundance and mass number of the naturally occurring isotopes.
Since, the average atomic mass of the hydrogen is nearest to 1 then, the most abundant isotope should be hydrogen-1.
