Answer: The rate of the reaction decrease over time as the reaction proceeds, a decrease in the concentration of reactants results in fewer successful collisions.
Explanation:
Rate of a reaction is defined as the change in concentration of products and reactants with respect to time.
The rate of a reaction decreases with times because reactants are converting into products.
As a result, the reaction is proceeding with a decrease in the concentration of reactants due to which less number of collisions between the reactant molecules will be there.
Hence, rate of reaction will decrease.
Thus, we can conclude that the rate of the reaction decrease over time as the reaction proceeds, a decrease in the concentration of reactants results in fewer successful collisions.
You calculate the mass using dimensional analysis.
We are given with
The weight of the chain per unit length which is 2.16 kg/m
We are also given with the needed length of the chain which is 7.0 m
Therefore, the mass of the chain is
7.0 m x 2.16 kg / m = mass of the chain in kg<span />
Balanced chemical reaction: 2Na(s) + F₂(g) → 2NaF(s) + energy.
This is exothermic reaction (energy or heat is released), because reactants have higher energy than products of reaction.
In ionic salt sodium fluoride (NaF), fluorine has electronegativity approximately χ = 4 and sodium χ = 1 (Δχ = 4 - 1; Δχ = 3), fluorine attracts electron and it has negative charge and sodium has positive charge.
Answer:
homogeneous mixture
Explanation:
two or more substances
a component that dissolves and a solvent
Answer:
The answer to your question is Sediment C
Explanation:
Permeability is the property of passing through a material without physically or chemically affecting it.
If a substance is very permeable, it will pass through a material rapidly others substances can be permeable but can not pass through the material quickly.
In the data given, we can conclude that the third substance is the least permeable because less quantity of water has passed through it.
