What may happen if the oceanic plates stop moving?
My name is Ann [436]
If all plate motion stopped, Earth would be a very different place. The agent responsible for most mountains as well as volcanoes is plate tectonics, so much of the activity that pushes up new mountain ranges and creates new land from volcanic explosions would be no more. The volcanoes of the Pacific Ring of Fire, in South and North America, Japan, the Philippines, and New Zealand, for example, would shut off, and the steady southeastward migration of volcanic activity along the Hawaiian Islands would stop. Volcanism would just continue on the big island. There would also be far fewer earthquakes, since most are due to motion of the plates.

My question today is : The reaction of 11.9g go CHCl3 with excess chlorine produced 10.2g of CCl4, carbon tetrachloride. What is
Helga [31]

Answer:

66.7%

Explanation:

Step 1: Write the balanced equation

CHCl₃ + Cl₂ ⇒ CCl₄ + HCl

Step 2: Calculate the theoretical yield of CCl₄ from 11.9 g of CHCl₃

According to the balanced equation, the mass ratio of CHCl₃ to CCl₄ is 119.38:153.82.

11.9 g CHCl₃ × 153.82 g CCl₄/119.38 g CHCl₃ = 15.3 g CCl₄

Step 3: Calculate the percent yield of CCl₄

Given the experimental yield of CCl₄ is 10.2 g, we can calculate the percent yield using the following expression.

%yield = (exp yield/theo yield) × 100%

%yield = (10.2 g/15.3 g) × 100% = 66.7%

Hello can anyone help?
e-lub [12.9K]

Answer:

A ) 1, 2 and 3

Explanation:

1 ) is correct because,

K donates 1 electron

F gain 1 electron from K.

If donating and gaining of electrons takes place between two electron, then type of compound formed is ionic.

2 ) is correct because,

K + F -----> KF

3 ) is correct because,

KF is soluble in cold water; very soluble in hot water.

QveST [7]

Answer:

Organelles, prokaryotic, organelles, cytoplasm, prokaryotic, nucleus

Explanation:

<u>Organelles</u> are membrane bound only in eukaryotic ccells.

Prokaryotic cells unlike eukaryotic cells, do <u>not have membrane bound organlles.</u>

Something that is found in <u>both prokaryotic and eukaryotic cells is the cytoplasm</u>, which is fluid that is inside the whole cell.

Unlike eukaryotic cells, <u>prokaryotic cells have loose DNA</u>, which floats around the cell quite literally.

The only way DNA is stored in eukaroyotic cells is in the <u>nucelus</u>, which is only found in eukaryotic cells, not prokaryotic.

Hope this helps ;)
