Explanation:
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
The carbon is considered because it is form by oxygen atoms
1 kilo joule = 0.239006 calories
134 kilo joule = 134 x 0.239006
= 32.026804 calories
Explanation:
Nitrous oxide or dinitrogen monoxide can be simple be prepared by the decomposition of ammonium nitrate in the following way -
<u>The reaction is as follows -</u>
NH₄NO₃ ----------------> N₂O + H₂O
This is the unbalanced reaction as was asked in the question , without mentioning the states of matter .
The reaction is carried out in an anhydrous condition ,since , ammonium nitrate can explode on heating .
I think the correct answer from the choices listed above is the third option. The element that will have similar chemical properties to francium would be rubidium since they are in the same column. <span>Groups of </span>elements in the same<span> column have similar </span>chemical <span>and physical </span>properties<span>, reflecting the periodic law.</span>
