Answer:
0.5M
Explanation:
The equation for molarity is:
M = [tex]\frac{mol}{liters}[/tex] ; where the "M" stands for molarity, the "mol" stands for moles of solute and the "liters" means the volume in liters of solution.We are given that there are:
1.80 moles of NaCl (the moles of solute)3.60 Liters of solution (the volume in liters of solution)Now we just plug those numbers into the formula and get our answer:
M= [tex]\frac{1.80mol}{3.60L}[/tex]= 0.5MAfter doing the math and dividing the moles of solute by the liters of solution, we get that the molarity of the solution is 0.5M.
how do different stimuli affect the survival behavior of an organism?THIS IS THE SECOND TIME IM ASKING PLZZZZ HELP ME
Answer:
Organisms change their behavior in response to changes in the surrounding environment.
Explanation:
All living things can respond to stimuli in the exterier environment, It is a form of energy—light waves or sound vibrations, From what they sense they will make neccisary changes to their diet and or where they are located.
Such as winter weather which is a type of stimulus will cause some animals to start hibernating.

An elements identity is decided by how many_____
it has.
Answer:
Number of protons!!
Explanation:
Answer:
An elements identity is decided by how many PROTONS it has.
Emily and Jack are working on their chemistry homework together. Jack explains to Emily
that when element "B" reacts, it will gain one electron and become negative since
electrons are negative. Emily asks if this same element can become negative by taking
away a proton. If you were Jack, what would you explain to Emily?
the protons is theato.m if you take one away you change the element
Explanation:protons determine the element take away the proton and the element changes. That means that the same element cannot become negatively charged by taking away the protons

in order to produce 3 moles of o2 how many moles of NaClO3 are required
Answer:
2 moles NaClO3
Explanation:
2NaClO3 --> 2NaCl + 3O2
moles NaClO3 = 3 moles O2 x (2 moles NaClO3/3 moles O2) = 2 moles
conversion factor: 2 moles NaClO3 = 3 moles O2
In order to produce 3 moles of [tex]O_{2}[/tex], the chemical reaction needs to be balanced. the required number of moles of [tex]NaClO_{3}[/tex] are 2.
What is a balanced chemical reaction?When the reactants undergo a chemical reaction, the number of moles on both the reactant and the product side must be balanced.
The chemical reaction of [tex]NaClO_{3}[/tex] is
2 [tex]NaClO_{3}[/tex]⇄2NaCl + 3 [tex]O_{2}[/tex]
On the left side, 2 moles of [tex]NaClO_{3}[/tex] breaks into 2 moles of NaCL and 3 moles of [tex]O_{2}[/tex]. on the right side. Therefore, both side have an equal number of moles of each element.
Hence, two moles of [tex]NaClO_{3}[/tex] is required to produce 3 moles of [tex]O_{2}[/tex].

When an atom of calcium (Ca) forms an ion by losing two electrons, what is the ion’s type and charge?
cation, 2+
anion, 2−
cation, 2−
anion, 2+
Answer:
cation +2
Explanation:
A cation is a positively charged ion, while an anion is a negatively charged ion. Contrary to how it sounds, when an atom loses electrons, it's charge becomes more positive. Since the calcium atom lost 2 electrons, it is a positive (+2) ion.
The electrical charge of the calcium ion is +2.
