Answer:
See explanation
Explanation:
11.19:88.81 is a ratio of about 8, meaning that the weight of oxygen is 8 times the weight of hydrogen in water. Since a single oxygen atom has 16 times the weight of a single hydrogen atom, this means that there are 2 hydrogen atoms for each oxygen, which confirms something you already know. Since the proportions stay constant, you know that in a 100g sample of pure water, there will be about 11.19 grams of hydrogen and 88.81 grams of oxygen. Hope this helps!
Answer:
The correct answer is - the uterus.
Explanation:
The uterus or the womb is an organ that appears to be pear-shaped and it is hollow from inside where the fetus is developed and it is also called the birth canal. The uterus has two parts one is the cervix and the other is the corpus.
The cervix makes the lower part of the uterus and opens up into the vagina the external reproductive organ of the females. The corpus is the part that makes the main body of the uterus. The uterus is present between the bladder and rectum where the egg fertilized and implanted itself.
Answer:
The answer to your question is 6 moles of oxygen
Explanation:
Data
methanol = CH₃OH
number of moles = 4
moles of oxygen = ?
Process
1.- Write and balance the chemical reaction
2CH₃OH + 3O₂ ⇒ 2CO₂ + 4H₂O
Reactants Elements Products
2 Carbon 2
8 Hydrogen 8
8 Oxygen 8
2.- Calculate the moles of oxygen
2 moles of methanol ----------------- 3 moles of oxygen
4 moles of methanol ------------------ x
x = (4 x 3) / 2
x = 12/2
x = 6
Supersaturated is when a solution holds more solute than can normally hold/ normally be dissolved.
Answer:
K=1.93
Explanation:
Given reactions are:
A +2B ⇄ 2C K1=2.79
2C ⇄ D K2=0.186
D⇄ A+ 2B K=?
If we reverse the reaction then the euillibrium constant also become reciprocal of original value:
3rd reaction is a combination of reciprocal of 1st and 2nd reaction
2C⇄A +2B 1/K1;........................1
D ⇄ 2C 1/K2; ..............................2
On adding 1 and 2
D ⇄A +2B
K=1.93
