#1. An element or ion that has lost two electrons must have a net charge of 2+, because it has two more protons than electrons, therefore the answer is Mg2+

#2. aluminum ions have an oxidation state of 3+ and fluoride has an oxidation state of 1-, therefore I’m order for the charges to cancel you need 3 fluoride ions.
Therefore, the answer is AlF3

If the reactants contain one chlorine molecule, do you know how many chlorine atoms will be in the product? Include conversion o
max2010maxim [7]

Answer:

The number of Chlorine atoms in the product is 2.

Explanation:

The law of conservation of mass states that matter can neither be created nor destroyed in a chemical reaction.

The reactants contain one chlorine molecule(Cl_{2}) which has two chlorine atoms.

Then, according to law of conservation of matter, the product must contain two chlorine atoms.

What conclusion can you make about electrons and the periodic table?
kogti [31]

Answer:

The number of valence electrons can be known from the group that the element is in (except the lanthanides, actinides and groups 3-12).

Explanation:

Group 1 has 1 valence electron. Group 2 has 2 valence electrons. Group 13 has 3 valence electrons. Group 14 has 4, group 15 has 5, group 16 has 6, group 17 has 7, and group 18 has 8.

Group 18 are the noble gases which are stable.

Group 17 are the halogens and react well with the alkali metals.

Dawson decided he would be Dawson and play with a flammable gas. He needs to know how many moles of gas it takes to occupy 210 L
Montano1993 [528]

According to ideal gas equation, 0.5186 moles of gas are required to occupy 210 L at a pressure of 5.4 atmospheres and a temperature of 263 K.

<h3>What is ideal gas equation?</h3>

The ideal gas equation is a equation which is applicable in a hypothetical state of an ideal gas.It is a combination of Boyle's law, Charle's law,Avogadro's law and Gay-Lussac's law . It is given as, PV=nRT where R= gas constant whose value is 8.314.The law has several limitations.

Substituting the given values in the given equation, n= 5.4×210/8.314×263=0.5186 moles

Thus there are 0.5186 moles occupying  210 L at a pressure of 5.4 atmospheres and a temperature of 263 K.

What is the act of adding fluid such as distilled water to a powdered or crystaline form?
nata0808 [166]

Reconstitution is the act of adding fluid such as distilled water to a powdered or crystalline form.

Additionally, medications are frequently provided in dry form, such as powders or crystals, which must be reconstituted with liquid before being injected parenterally. To create a specified liquid concentration, a dry ingredient is reconstituted by adding a liquid diluent. To ensure that the drug is reconstituted in the exact concentration, it is crucial to carefully follow the reconstitution instructions. The quantity of fluid used to dilute the drug must also be taken into account when determining the dosage of reconstituted medication to provide to the patient.
