Organelle? 3 types of organnelles?

Answers

Answer 1
Answer: Hey there, 3 types of organelles are Rough Endoplasmic Reticulum, Smooth Endoplasmic Reticulum, and Mitochondria. The Rough Endoplasmic Reticulum it's density is higher near the nucles. The Smooth Endoplasmic Reticulum is an organelle that's in an animal cell and plant cells. The Mitochondria is an organelle that is found in large numbers in most cells.

What is the chemical equation for the burning of propane if all the products and reactants are in the gas phase?4H2O(g) + 3CO2(g) + 5O2(g) → C3H8(g)


C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)


C3H8(g) + O10(g) → 3CO2(g) + 4H2O(l)


4H2O(l) + 3CO2(g) → C3H8(g) + 5O2(g)



Answer - B -
C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)

Answers

Propane is a hydrocarbon and it will burn in presence of oxygen (it will undergo combustion) to give carbon dioxide and water (all in gas phase).

In presence of oxygen the carbon gets oxidized to carbon dioxide and hydrogen to water.

The general equation for a hydrocarbon undergoing combustion is

CxHy(g)  + (x+(y)/(4))O_(2)  ---> xCO_(2)(g)   +(y)/(2)H_(2)O(g)

Here we are studying the combustion of propane so

x = 3

y = 8  

Propane has molecular formula of C3H8

Therefore the balanced equation will be

C3H8(g)  + (3+(8)/(4))O_(2)  ---> 3CO_(2)(g)   +(8)/(2)H_(2)O(g)

Or

C3H8(g)  +   5O_(2) (g)  ---> 3CO_(2)(g) + 4H_(2)O(g)

Why is radon gas hazardous?

Answers

Answer:

Usually lung cancer.

Explanation:

It causes cells in your lungs to be damaged, which can lead to lung cancer.

Usual symptoms include

persistent cough

coughing up blood

wheezing

shortness of breath

hoarseness

chest pain, especially when you cough or laugh

frequent infections such as bronchitis and pneumonia

Radon is part of the environment and generally isn’t harmful. But long-term exposure to high levels of radon can put you at risk of developing lung cancer, especially if you smoke

What is the volume of a liquid with a density of 5.45g/ml and a mass of 65g

Answers

you have to use the fact that d=m/v and solve for v (v=m/d). with that equation you just divide the mass of the liquid by the density of the liquid.  When done correctly you should get 11.93 mL of liquid.

I hope this helps.

READING CHECK1. What is always true about the
kinetic energy of a single particle
in a gas?

Answers

Gas particles are in constant motion, and any object in motion has kinetic energy (Ek). ... For example, in the collision of two molecules, one molecule may be deflected at a slightly higher speed and the other at a slightly lower speed, but the average kinetic energy does not change.
