The statement which explains why a balloon can fold, twist, and bend without bursting is: B. The balloon is filled with air, which is a mix of gases. Air is fluid and can move around the inside of the balloon as it is folded.
A balloon can be defined as a flexible rubber bag that can be inflated with a gas such as air.
Generally, air can be trapped in a balloon by sealing its neck tightly.
Hence, this makes it possible for performers and clowns to fold, twist, and bend an inflated balloon into animals and objects as toys for children.
A inflated balloon can be folded without it bursting simply because air is fluid and as such, it would move around the inside of the balloon as it is folded.
In conclusion, air, which is a mixture of gases would move around the inside of the balloon as it is folded because it is also a fluid.

Answer:
THE EQUILIBRIUM CONSTANT EXPRESSION Kc = ![\frac{[C2H5OH]}{[C2H5OC2H5]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BC2H5OH%5D%7D%7B%5BC2H5OC2H5%5D%7D)
Explanation:
The equilibrium constant, Kc is an expression given by the ratio of the concentrations of the products over the reactants. TN.B: the activities of pure solids and liquids are equal to 1.
Kc = ![\frac{[products]^n}{[reactants]^n}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bproducts%5D%5En%7D%7B%5Breactants%5D%5En%7D)
where n= no of moles
Reaction equation:
2C2H5OH 
→ C2H5OC2H5
⇒ Kc = ![\frac{[C2H5OC2H5] [H2)]}{[C2H5OH]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BC2H5OC2H5%5D%20%5BH2%29%5D%7D%7B%5BC2H5OH%5D%5E2%7D)
but [H20] = 1
∴ Kc =
Answer:
1.292 M
Explanation:
<em>In order to calculate the concentration of H2SO4, we need to get the balanced equation of reaction first;</em>
Using the formula:
CaVa/CbVb = na/nb
where Ca = concentration of acid, Va = volume of acid, Cb = concentration of base, Vb = volume of base, na = number of moles of acid, and nb = number of moles of base.
In this case, Ca =?, Va = 10.00 ml, Cb = 0.777, Vb = 33.25 ml, na = 1, nb = 2
Ca = CbVbna/Vanb = 0.777 x 33.25 x 1/10 x 2
Ca = 1.292 M
Hence, the concentration of H2SO4 is 1.292 M
Answer:
c
Explanation:
glycolysis is the breakdown of glucose to form pyruvic acid and 4 ATP
so I think with this definition. ATP is produced within a cell at a given period of time during glycolysis resulting to the increase in the amount of ATP produced.
In a wheel and axle, force may be applied either to the wheel or to the axle. This force is called the input force. A wheel and axle does not change the direction of the input force.
hope it helps...!!!
