Answer:
living things are things that is living like us people, animals, and plants. but plants is considered as living things because they also live like human being. we need food, water, air/oxygen as well all we need to live or survive.
examples:
- humans, plants, trees, and different kinds of animals or insects
<h3>as long as it is alive, it is living things</h3>
Explanation:
hope it helps✨
The answer the comes closest to being correct would be answer choice D. the problem with it though is that it does not have the correct amout of neurtrons. It is called rubidium 87 therefor there must be 50 neurtrons if there are 37 electrons and protons 87-37=50, 50+37=87.
Answer:
Kp is 2.98 (option c.)
Explanation:
The decomposition is:
NH₄NO₃(s) → N₂O(g) + 2H₂O(g)
Total pressure at equilibrium is 2.72 bar so, in order to determine Kp we need the partial pressure and we only have total pressure.
According to stoichiometry, nitrogen oxide increase by 1, the partial pressure and water vapor, by 2.
Total pressure is: Partial pressure N₂O + Partial pressure H₂O
2.72 bar = X + 2X → X = 2.72 bar / 3 = 0.91 bar
Partial pressure N₂O = 0.91 bar
Partial pressure H₂O = 1.81 bar
We make the expression for Kp = Partial pressure N₂O . (P. pressure H₂O)²
Kp = 0.91 . 1.81² = 2.98
We do not consider the ammonium nitrate, because it is solid
The formula Ca(ClO3)2 breaks down to: 1 calcium atom, 2 chlorine atoms, and 6 oxygen atoms. Therefore:
One molecule of calcium chlorate contains 9 atoms [correct]
Calcium chlorate is not an element, nor does the molecule contain only 3 atoms [incorrect]
It does not take 9 different elements - just the three elements we listed [incorrect]
Calcium chloride only contains one Ca group [incorrect]
