Answer:
Explanation:
A property closely related to an atom's mass number is its atomic mass. The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu.

It should be 8 O atoms. 3O atoms in Na2S2O3 and 5O atom in 5H2O. The reason there are 5 O atoms are because the 5 in front of H2O means you multiply each atom in the compound by that number (like the distributive property). The H2 molecule becomes 10 Hydrogen atoms (5*2) and the Oxygen becomes 5 Oxygen atoms (5*1). Then you add the 5O atoms to the 3O atoms which equals 8

Answer;
-Acceleration: 10 km/h/s east
Explanation;
-The quantity is either a vector or a scalar. Scalars are quantities that are fully described by a magnitude (or numerical value) alone while Vectors are quantities that are fully described by both a magnitude and a direction.
Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
In this case , a =( v-u)/t ; where a is the acceleration, v is the final velocity, u is the initial velocity and t is time.
a = (60 - 0)/6
= 10 km/h/s
