A mole ratio is the ratio between the amounts in moles of any two compounds involved in a chemical reaction. Mole ratios are used as conversion factors between products and reactants in many chemistry problems. Ratios are written like- #:#
They attract each other to form ionic networks.
(1) an effective collision between reacting particles
Explanation:
In order for a chemical reaction to occur, an effective collision between reacting particles must always be.
- Based on the collision theory, for reactions to occur, there must be collisions between the reacting particles.
- It implies that the rate of reaction depends on the number of collision per unit time as well as the fraction of this collision that is successful or effective.
- For collisions to be effective, they must have adequate energy.

Answer:
Anions name is given to a non-metal when it forms an ion, and it has negative charge.
Answer:
a = -2.4 ms⁻²
Explanation:
Given data:
Initial velocity of car = 37.1 m/s
Final velocity of car = 29.8 m/s
Time taken to change velocity = 3 sec
Acceleration of car = ?
Solution:
Formula:
a = Vf - V₀ / t
Vf = Final velocity
V₀ = Initial velocity
a = acceleration
t = time taken to change velocity
Now we will put the values in formula.
a = 29.8 m/s - 37.1 m/s / 3 s
a = -7.3 m/s/ 3s
a = -2.4 ms⁻²
Negative sign show that car is slowing down.
