The answer would be Ca + FeN = Ca3N2 + 2Fe
Answer:
Explanation:
Because the image of the graduated cylinder in your question was not attached when sending it in, I have attached one which I would use to explain the answer given.
In taking readings of liquids from a measuring cylinder, you must be at eye level from the apparatus, after which you are to take reading from below the meniscus (the lower curve) of the water.
From the image I attached, that would be 24ml.
Please apply the following to your image. I hope this was helpful.
Answer:
it will reach the house in 3 hours
Explanation:
20km x 3h = 60km
No It is not correct.
Correct oxidation number of hydrogen in NaH,H2 and H2S are:
- Let x be the Oxidation state of ’H’ by oxidation state rule.
x+1 =0 (Sodium has +1 Oxidation state )
x=−1
Therefore, -1 is oxidation number of Hydrogen in NaH.
- The oxidation number of an element's atom in its standard state is zero. As a result, the oxidation number for H2 is zero.
- The hydrogen oxidation number in H2 is +1. As a result, that hydrogen atom can be reduced to lower oxidation states of hydrogen, such as 0 and -1. However, because +1 is the highest oxidation state of hydrogen, the hydrogen atom cannot be reduced any further.
<h3>What is oxidation number?</h3>
In simple terms, the oxidation number is the number assigned to elements in a chemical combination. The oxidation number is the number of electrons that atoms in a molecule can share, lose, or gain when forming chemical bonds with atoms of a different element.

On a topographic map, the contour lines follow a certain elevation across the terrain. So here's what each of the things you mention would mean: If the lines are far apart, that means that there is little or no slope in that area of the map
