What is the great pacific garbage patch

Biology
1 answer:
levacccp [35]3 years ago
6 0

Answer:

The<em> Great Pacific Garbage Patch </em>is a 1.6 million kilometer long patch of garbage on the ocean. It is about three times the size of France and twice the size of Texas. It is an area on the surface where garbage has gathered form all over, it is extremely difficult to try and cleanup, because the water's gyres drag the pollution all over the ocean and dump it onto coastlines, shores, habitats, coastal reefs, and even deep into the oceans. Scientists are trying to solve this enviormental issue everyday and are brainstorming new ideas to solve this giant problem.

Solid sodium reacts with liquid water to form hydrogen gas according to the equation 2 Na(s) + 2 H₂O(l) → 2 NaOH(aq) + H₂(g) Wha
lana66690 [7]

Answer: 21850.42mmHg or 28.78atm

Explanation: From the equation of the reaction, 2 moles of sodium reacts with 2 moles of water to produce 2 moles of NaoH and 1 mole of hydrogen gas at s.t.p.

molar volume of gas at s.t.p. = 22.4dm^3,

standard temperature = 0°C or 273K,

standard pressure = 760mmHg or 1atm,

molar mass of Na = 23g;

volume of the container= 20L or 20dm^3

From the equation, 2 moles or 46g of Na produces i mole or 22.4 dm^3 of hydrogen.

Therefore, 1kg or 1000g of Na will produce 22.4 * 1000/(46)= 486dm^3 of hydrogen.

To find the pressure of the gas produced, the formula P1V1/T1 = P2V2/T2

P1= 760mmHg, T1= 273K, V1 (initial volume of gas)= 486dm^3, T2=50.0°C or 50+273K= 323K, V2( final volume of gas= volume of vessel)=20dm^3  P2=?

P1= P1V1*T2/(V2T1)= 760mmHg * 323/(273)= 21850.42mmHg or 1atm*21850.42/760= 28.78atm

Describe what happens during cell division
katovenus [111]

Answer: Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
