What are your answer choices? Scientists express the weight in AMU’s so that they can easily think about the weight of the atom. If it is expressed in grams, they’re constantly dealing with a weight that’s around 10^-24 grams, which is hard to deal with.
Answer: The moles of carbon needed will be, 13.8 moles
Explanation: Moles of = 5.52 mole
Now we have to calculate to moles of carbon.
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that
As, 2 mole of react to give 5 moles of carbon
So, 5.52 mole of react to give moles of carbon
Therefore, the moles of carbon needed will be, 13.8 moles
Answer:
"To ensure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance."
Explanation:
Hello,
The OSHA -Occupational Safety and Health Administration- is an agency of the United States Department of Labo signed into law on December 29, 1970. It was created to prevent workers from being killed or seriously harmed at work. The law requires that employers provide their employees with working conditions that are free of known dangers.
The mission is "to ensure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance."
Best regards.
Answer:
The inner core
Explanation:
Well, Jaron's tunneling machine would find it quite impossible to even penetrate the crust.
Our dynamic earth is arranged in concentric layers with each shell at varrying physical state and chemical properties.
As we go down the earth, the temperature and pressure increases significantly. The innermost layer of the erth is the inner core and it is expected that the temperature and pressure here should be the greatest. The pressure in the inner core is so great that the materials that were supposed to be in molten form exists as solid in there.
Here we have to get the moles of hydrogen (H₂) consumed to form water (H₂O) from 1.57 moles of oxygen (O₂)
In this process 3.14 moles of H₂ will be consumed.
The balanced reaction between oxygen (O₂) and hydrogen (H₂); both of which are in gaseous state to form water, which is liquid in nature can be written as-
2H₂ (g) + O₂ (g) = 2H₂O (l).
Thus form the equation we can see that 1 mole of oxygen reacts with 2 moles of hydrogen to form 2 moles of water.
So, 1.57 moles of oxygen will consume (1.57×2) = 3.14 moles of hydrogen to form water.
