Answer:
Explanation:
Hello,
In this case, considering that the safe temperature may be computed via the ideal gas law as we now the pressure, mass and volume via the dimensions:
The pressure in atm is:
And the moles considering the mass and molar mass (66 g/mol) of dinitrogen difluoride (N₂F₂):
In sich a way, by applying the ideal gas equation, which is not the best assumption but could work as an approximation due to the high temperature, the temperature, with three significant figures, will be:
Best regards.
Explanation:
One positive impact of the mining is that the sale of the Bauxite will increase their economic power by bringing in foreign exchange into their economy. This will improve services such as healthcare and infrastructure.
A negative impact is the destruction of the nature preserve and disturbing the ecosystem could lead to a devastating loss in biodiversity. A decrease in biodiversity will increase crop pests and diseases that destroy standing crops, and an increase in the prevalence of diseases in the community.
Answer:
The 2 in the formula means that, there are 2 phosphate anions that forms the salt.
Explanation:
Magnesium phosphate is a ionic salt.
The formula indicates that 3 moles of Mg and 2 moles of anion phosphate are contained in 1 mol of compound.
3Mg²⁺ + 2PO₄⁻³ → Mg₃(PO₄)₂
The phosphate anion comes from phosphoric acid and it is generated when the acid loses the 3 protons.
H₃PO₄ → 3H⁺ + PO₄⁻³
Phosphate has a negative charge of -3, so when it bond to magnesium, which has a charge of +2, there must be 3 magnesium and 2 phosphate to make a global charge +6 -6 in the ions
A molecule with a trigonal bipyramidal electron geometry must have a central atom with how many bonding and nonbonding electron groups around it Equatorial.
A molecule is made up of one or more atoms. If they contain multiple atoms, those atoms can be the same (the oxygen molecule has two oxygen atoms) or different (the water molecule has two hydrogen atoms and one oxygen atom). Biomolecules such as proteins and DNA are made up of thousands of atoms.
Water is a simple molecule with one oxygen atom bonded to two different hydrogen atoms. The bond is a polar covalent bond (polar bond) due to the high electronegativity of the oxygen atom.

Answer:
Base on the properties the substances possess the substance change phase from gas to liquid.
Explanation:
Generally, matter can exist in three phase namely liquid , solid and gas. The scientist has a container with a substance inside.
At first the substance moves away from each other . This means the substance was first in the gas phase . Gas molecules, because of the energy they possess , it can move rapidly and randomly and most at times move away from each other . The gas molecules tends to fill the whole volume of the container and the shape of gases are indefinite.
Later the molecules move around each other. This is a property of a liquid . A substance in liquid phase have the ability to move freely but they stay together because of the force of attraction holding them together . The substance only have the ability to move around each other because the forces holding them together won't allow them to move apart.
Base on the properties the substances possess the substance change phase from gas to liquid.
