Answer:
The weight of the displaced water is equal to the upthrust acting on the stone which is less than the weight of the stone thus the stone sinks to the bottom of the beaker. This is according to the Archimedes principle which states that when an object is partially or wholly immersed in a fluid the weight of the displaced fluid is equal to the upthrust acting on the object.
Answer:
The most dangerous area for animals and plants is the one that contains the greatest biodiversity on the planet: Southeast Asia. In this region are the five most affected countries in the world: Malaysia, Brunei, Singapore, Indonesia and Thailand. The Atlantic rainforests of Brazil are also very affected, this is due to the fact that great catastrophes have occurred in these places lately, such as the massive fire in the Amazon, and the floods that occurred after the tremendous absence of vegetation that these places suffered.
Explanation:
Also on the other hand, the regions with the highest extinction are those that carry out little environmental policies where care has not been taken for species that are in danger of extinction, as happens, for example, in those islands such as the Galapagos Islands, which are subject to severe fines for harm turtles.
oxygen, hydrogen, sulfur, iodine, iron, carbon, nitrogen, phosphorus, calcium.

Answer:
LR is Na₃PO₄
Explanation:
A quick way to determine the limiting reactant in a process is to convert reactant values to moles and then divide by the respective coefficient of the balanced equation. The smaller number of the division is the limiting reactant. For the given reaction, the rxn ratio of reactants is 1:1 so only the smaller mole value gives limiting reactant. However, if the reaction is NOT 1:1 the one must divide by respective coefficient to identify the smallest value and the limiting reactant.
This problem:
FeCl3(aq) + Na3PO4(aq) => FePO4(s) + 3 NaCl(aq)
Given: 27.8g 61.9g
moles: 27.8g/162.2g/mole 1.9g/163.94g/mole
= 0.1714 mole = 0.0116 mole
÷ coef. => 0.1714/1 = 0.1714 => 0.0116/1 = 0.0116
smaller value is LR => => => => => => LR is Na₃PO₄
Hope this helps. Doc :-)
