Zac releases the air from a balloon. Which statement best describes what will happen to the air that was inside the balloon?

The correct answer is the last option. When Zac releases the air from a balloon, it will expand to fill the room. It will not expand in the sense that molecules will be big but the molecules will be more spread out into the room and more air molecules will be present to fill the room.

When Zac releases the air from a balloon, it will expand to fill the room. It will not expand in the sense that molecules will be big but the molecules will be more spread out into the room and more air molecules will be present to fill the room.

Explanation:

As the air inside the balloon is burned its volume rises, inflating the balloon more completely. Having a greater volume makes it less dense than the neighboring air so it glides upward

When we open the balloon, the air is delivered to the air inside the balloon is at the corresponding pressure as the air outside the balloon. When this occurs, the air emerging from the balloon results in a force in the reverse direction sending the actual balloon in the opposite direction. And it expands to fill a room.

Benzene is an organic chemical compound with the molecular formula C6H6. In the benzene molecule, carbon atoms form a ring with

Sergeu [11.5K]

Answer:

$sp^2$

Explanation:

Hello,

The six-carbon benzene ring contains two types of bonds: C-C and C-H bonds, that are $sp^2$ -hybridized σ bonds, and the six π bonds that form the aromatic ring. The σ bonds form from one $s$ orbital and two $p$ orbitals from each carbon, which then bond the carbon to the two carbons on either side and the carbon's single hydrogen. The remaining $p$ orbital from each carbon atom sticks out above and below the plane of the ring; these $p$ orbitals overlap sideways, rather than lengthwise, to form the aromatic π bond system.

Best regards.

The half-life for the radioactive decay of C-14C-14 is 5730 years. You may want to reference (Pages 598 - 605) Section 14.5 whil

KIM [24]

Answer: The sample of Carbon-14 isotope will take 2377.9 years to decay it to 25 %

Explanation:

The equation used to calculate rate constant from given half life for first order kinetics:

$t_{1/2}=\frac{0.693}{k}$

where,

$t_{1/2}$ = half life of the reaction = 5730 years

Putting values in above equation, we get:

$k=\frac{0.693}{5730yrs}=1.21\times 10^{-4}yrs^{-1}$

Rate law expression for first order kinetics is given by the equation:

$k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}$

where,

k = rate constant = $1.21\times 10^{-4}yr^{-1}$

t = time taken for decay process = ? yr

$[A_o]$ = initial amount of the sample = 100 grams

[A] = amount left after decay process = (100 - 25) = 75 grams

Putting values in above equation, we get:

$1.21\times 10^{-4}=\frac{2.303}{t}\log\frac{100}{75}\\\\t=2377.9yrs$

Hence, the sample of Carbon-14 isotope will take 2377.9 years to decay it to 25 %

Does someone know the combustion in a jacket potato???

Leya [2.2K]

Answer:

Some varieties of potato, such as Russet and King Edward, are more suitable for baking than others, owing to their size and consistency. Despite the popular misconception that potatoes are fattening, baked potatoes can be part of a healthy diet.[2]
