Answer:
Greater than zero, and equal to the rate of the reverse reaction
Explanation:
this is an incomplete question in the first place, i saw the complete format online hence the answer am giving here.
Before any C2H5CO2CH3 is or was removed, the system is said to be in equilibrium.
This means that the rate of consumption of reactants and rate of generation of products are greater than zero and are equal, that means that both the forward and backward reactions are occurs at these rate.
The mass number is the sum of the number of protons and number of neutrons the atom has.
So, we can write the equation as:
x + 20 = 40
x = 20 neutrons.
Answer:
d. All of the above
Explanation:
Wildfires are useful in controlling the ecosystem disturbed due to some diseases and insects.
With the help of wildfire, there will be a temporary loss in some region but it will lead to extraordinary growth.
Wildfire improves the soil quality by decomposing the organic material and renewing the soil nutrients.
There are chances of habitat loss but it will increase the production of food grazers.
Certain plants can be reproduced through wildfire due to cracking their seeds.
Your answer would be c because smooth is good
Answer:
The correct answer would be - 1. group 2.period 3. less 4. more
Explanation:
elements that have a place with same group contains same number of valence electrons. Thus, they will in general show comparable chemiccal properties.
At the point when we move over a period at that point number of electrons get added to a similar shell. Therefore, there will be no expansion in size of elements.
Additionally, metals are the elements that have a place with group 1, 2 and d-block group are otherwise called metals. Metallic character of elements diminishes when we move left to directly in a periodic table.
As most responsive metals are put on the left half of occasional table.
Since, size of elements increases on descending the groups. Along these lines, a elements can lose its valence electrons due to the less forrce of ttaraction between valence electrons and its neucleus.
