How do a hypotonic solution cause a cell to rupture?

SAT
1 answer:
Pepsi [2]3 years ago
3 0
A hypotonic solution means the environment outside of the cell has a lower concentration of dissolved material than the inside of the cell. If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst. ... This can cause a cell to shrink and shrivel

The equation: 2pb(no₃)₂ --> 2pbo + 4no₂ + o₂ shows the decomposition of lead nitrate. How many grams of oxygen are produced w
SashulF [63]

Answer:

Explanation:

Hi there!

2Pb (no₃) -------> 2Pb + 4no₂ + o₂

Molecular mass of 4no₂ = 184g

Molecular mass of o₂ = 32g

From the reaction;

When 184 g of no₂  was formed 32 g of oxygen was formed.

When 1 g of no₂  was formed 32/184 g of oxygen was formed.

When 11.5 g of no₂  was formed (32/184)*11.5 g of oxygen was formed.

Therefore, when 11.5 g of no₂  was formed 2 g of oxygen was formed.

Hope it helps!

Why is it important to distress?
Anna35 [415]
I agree with the person above.
Prolonged stressing causes mental illnesses such as depression, anxiety, and personality disorders.
It causes physical illnesses such as cardiovascular disease, high blood pressure, abnormal heart rhythms, heart attacks, heart disease, and strokes.

Ways to distress are things like exercising, eating healthy, meditate, take a deep breath in and out, and find a hobby that helps you distress. Also I would full heartedly recommend watching Bob Ross.

There are 23 countries in North America, 12 countries in South America, 47 countries in Europe, 44 countries in Asia, 54 countri
natta225 [31]

The probability for each event follows below:

P(A)= 0.23

P(E)= 0.24

P(F)= 0.28

P(N)= 0.12

P(O)= 0.07

P(S)= 0.06

<h3>Probability</h3>

Probability can be defined as the possibility that an event will occur. For an event, the probability can be found from the ratio between the number of favorable outcomes for the event and the total number of outcomes.  Values of probability vary between 0 and 1.

A probability for an event is represented by P(A), P(B), etc. And exactly this that question asks for you.

1. Arrange the text of the question

       North America=23 countries

       South America= 12 countries

       Europe=  47 countries

       Asia= 44 countries

      Africa =54 countries

      Oceania= 14 countries

2. Find the total of countries

N_{total}=23+12+47+44+54+14=194

3. Find P(A)

A= the event that a country is in Asia= 44 countries. Therefore,

P(A)=\frac{numberofcountries of Asia}{Total number of countries } \\ \\ P(A)=\frac{44}{194} =0.23\\ \\ P(A)=0.23

4. Find P(E)

E= the event that a country is in Europe= 47 countries. Therefore,

P(E)=\frac{numberofcountries of Europe}{Total number of countries } \\ \\ P(E)=\frac{47}{194} =0.24\\ \\ P(E)=0.24

5. Find P(F)

F= the event that a country is in Africa= 54 countries. Therefore,

P(F)=\frac{numberofcountries of Africa}{Total number of countries } \\ \\ P(F)=\frac{54}{194} =0.28\\ \\ P(F)=0.28

6. Find P(N)

N= the event that a country is in North America= 23 countries. Therefore,

P(N)=\frac{numberofcountries of North America}{Total number of countries } \\ \\ P(N)=\frac{23}{194} =0.12\\ \\ P(N)=0.12

7. Find P(O)

O= the event that a country is in Oceania= 14 countries. Therefore,

P(O)=\frac{numberofcountries of Oceania}{Total number of countries } \\ \\ P(O)=\frac{14}{194} =0.07\\ \\ P(O)=0.07

8. Find P(S)

S= the event that a country is in South America= 12 countries. Therefore,

P(S)=\frac{numberofcountries of South America}{Total number of countries } \\ \\ P(S)=\frac{12}{194} =0.06\\ \\ P(S)=0.06
