True/False - Changing the temperature has no effect on the application of Graham's law?
Explanation:
By Graham's Law,
We have r1/r2 = √(M2/M1), where M represents the molar mass of the gas and r is the effusion rate.
Since temperature is not a variable here, the sentence is true.
Why can't krypton and xenon separate during the separation of gases in the air?
Answer:
The remaining gas is a mixture of argon, neon, krypton, and xenon. Because these elements are chemically very unreactive, chemical means cannot be used to separate them.
Explanation:
Answer:
They're in Group 0 as they have full outer shells meaning they are chemically unreactive as they already have full outer shells meaning they don't want to lose or gain any electrons. Thus, they can't separate during the separation of gases in the air.

find the name for this W(C2H3O2)4
The name for this W(C2H3O2)4 is the chemical formula for lead(IV) acetate, often known as lead tetraacetate, is Pb(C2H3O2)4.
What is chemical formula?Chemical formula is defined as any of a number of ways to describe the structure or content of chemical substances. The chemical formula is a way of expressing information about the atomic proportions that make up a certain chemical compound or molecule using the numbers and symbols of the chemical elements. The sorts of atoms and their numbers in a molecule or compound are described using chemical formulae. Each element's atoms are denoted by one or two distinct letters.
It is not a salt because it is a colorless solid that dissolves in nonpolar, organic liquids. Moisture causes it to break down, therefore acetic acid is usually added when storing it. The substance is utilized to create organic compounds.
Thus, the name for this W(C2H3O2)4 is the chemical formula for lead(IV) acetate, often known as lead tetraacetate, is Pb(C2H3O2)4.

The elements beryllium, calcium, and strontium are all in group 2. What is the correct relationship of these elements regarding their ionization energy?
A.
Ca < Be < Sr
B.
Sr < Be < Ca
C.
Be < Ca < Sr
D.
Sr < Ca < Be
E.
Ca < Sr < Be
Answer:
d. The correct answer for your questions is Sr<Ca<Be
Answer:
Answer:- choice d is correct. Sr<Ca<Be .
Explanations:- Br, Ca, and Sr are all elements of same group as they all have 2 valence electrons. As we move down in a group, a new shell is being added that increases the size of the atom. As the size of an atom increases, it is easy to remove the electron from it's outer most shell in it's gaseous state. Since, Be is above Ca and Ca is above Sr. The size increases in the order, Be < Ca < Sr. It means Be is the smallest one of them and so it's hard to remove from it's outer most shell and hence it's ionization energy is higher.
Sr is largest one in these three elements and so it's easy to remove outer most electron from it that means the ionization energy is least. Ca is between Be and Sr.
So, an increasing order of ionization energy is Sr<Ca<Be . Choice D is correct.

Explanation:
Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. ... Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. I also remember this from Science.

Answer:
Removing the worms is they first key to overcoming this problem. Thus you should ensure that the worms have not spread throughout the house/facility, or caused more damage.
Secondly, you should replace the pipes taht the worms got into, or clean them at most. If it’s simply worm droppings then just clean it, but if it’s more and worse than that alike slime then it is best to remove and replace it.
the only way the worms escaping could affect something is if they decontaminated it, or alas ate or destroyed it. Other than that if they died you could simply replace them, but e things cannot be replaced

The reaction represented by this graph is an exothermic reaction. According to the graph, which statement is true? Reactants have more energy than products. Products have more energy than reactants. Reactants and products have the same amount of energy.
Answer:
Reactants have more energy than products
Explanation:
Generally, in an exothermic reaction heat is released. In other words, energy is released. So you start with reactants which have a set amount of stored chemical energy, and you lose some in the reaction. Since energy is 'leaving', the stored chemical energy in the products is less than what we started with in the reactants. When given a graph, you can tell this is true because going from left to right, the line representing the stored chemical energy will start at a higher level than where it ends.
The true statement about an exothermic reaction is that reactants have more energy than products.
What is an exothermic reaction?An exothermic reaction is one in which the energy of reactants is greater than that of products. As such, energy is given off during the reaction in form of heat.
Thus, the true statement about an exothermic reaction is that reactants have more energy than products.
