Answer:
solid
Explanation:
in the solid state the material will has a fixed shape and volume whatever the container that contains it
where in liquid the shape will be different depending on the container
and in gas state the shape and volume are not definite
Answer:
Explanation:
When I was growing up, one of the most popular cartoons was a little possum whose name was Pogo. He often said
“We have met the enemy and he is us.”
It is something Pogo said more than once. We are the problem with biodiversity being threatened.
We clear land for agriculture, not only in Canada and the United States, but in places like Brazil where it matters what is done to the environment. Those trees are the planet's lungs. Whole environmental groups are devoted to stopping the harvesting of trees that are hundreds of years old.
Our oceans have become cesspools of plastic.
Our rivers have become dumping grounds for all kinds of pollutants like paint and car tires to name just a couple.
Our landscape has been cluttered by billboards advertising things that are hundreds of miles away.
There's mining, oil, and other industries that make Mother Nature shudder every time they come near her.
Answer :
<h2>
Multicellular organisms</h2>
Explanation :
Coyotes are multicellular organisms.
Trees are multicellular organisms. They are made up of eukaryotic cells, which are complex cells full of organelles.
The molarity of HCl is calculated as below
find the moles of mg used
moles = mass /molar mass
= 2.00g/24 g/mol=0.083 moles
write the reacting equation
Mg(s) +2HCl (aq)= MgCl2(aq) + H2(g)
by use of mole ratio between Mg to HCl which is 1 :2 the moles of HCl is therefore
= 0.083 x2 =0.166 moles
molarity of HCl = moles of HCl/ volume in dm^3
that is 0.166/50 x1000= 3.3 M of HCl
Answer: The equilibrium concentration of 
at 700 degrees Celsius is 0.0012 M
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
Moles of 
= 0.29 mole
Volume of solution = 3.0 L
Initial concentration of = 
The given balanced equilibrium reaction is,
Initial conc. 0.097 M 0M 0M
At eqm. conc. (0.097-2x) M (2x) M (x) M
The expression for 
is written as:
![K_c=\frac{[H_2]^2\times [S_2]}{[H_2S]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BH_2%5D%5E2%5Ctimes%20%5BS_2%5D%7D%7B%5BH_2S%5D%5E2%7D)
Equilibrium concentration of ![[H_2]](https://tex.z-dn.net/?f=%5BH_2%5D)
= 2x=
