These three gases, Helium, Neon, and Argon all have one property in common because they are gases at room temperature. That is they:
They have no definite shape and no definite volume because they are gases.
How gases have no definite and volume?Gases have no definite shape and no definite volume because they are present in free state. Those substances that are close together and held tightly have definite shape and volume.
So we can conclude that they have no definite shape and no definite volume because they are gases.

Find the formula for the hydrate
0.737 g MgSO3 and 0.763 g H2O
The required formula of hydrate is MgSO₃.6H₂O.
How do we calculate the formula of hydrate?The number of moles of water per mole of anhydrous solid (x) will be computed by dividing the number of moles of water by the number of moles of anhydrous solid (x) to find the hydrate's formula.
Moles will be calculated as:
n = W/M, where
Moles of MgSO₃ = 0.737g / 104.3g/mol = 0.007mol
Moles of H₂O = 0.763g / 18g/mol = 0.04 mol
Number of H₂O molecule = 0.04/0.007 = 5.7 = 6
So formula of hydrate is MgSO₃.6H₂O.
Hence required formula of hydrate compound is MgSO₃.6H₂O.

Answer:
23.2 C
Explanation:
By looking at the dimension of specific heat ( J/g-C) , you can compute these type of questions:
149.4 J / ( .129 J / g-C * 50 g) = 23.2 C
(see how dimensions g and J cancel out and you are left with C ? )
In the wild, female and juvenile African elephants typically live in herds that vary in size, depending on the
environment. Juvenile African elephants are subject to predation by animals such as lions and leopards. When a
juvenile is threatened by a predator the members of the herd may form a protective circle around that individual
and the other juveniles.
Explain how herd behavior is beneficial to the survival of individual elephants and also beneficial to the survival of
the species. Enter your answer in the box provided.
Herd behavior in elephants ensures that individuals are protected and the species is perpetuated.
What is her behavior?It is a behavior that is characteristic of animals that form herds.
Herds generally refer to groups of animals that live or move together or both.
By protecting individual elephants that are weak or young from being preyed upon by lions and leopards, more members of the population survive.
When more members of the population survive, the species is perpetuated and the likelihood of going into extinction reduces.

The following data was collected when a reaction was performed experimentally in the laboratory. Reaction Data Reactants Products Fe2O3 Al Al2O3 Fe Starting Amount in Reaction 3 moles 5 moles ? ? Determine the maximum amount of Fe that was produced during the experiment. Explain how you determined this amount.
The maximum amount, in grams, of Fe that would be produced during the experiment, will be 280 grams
Sotichiometric calculationFrom the equation of the reaction:
[tex]Fe_2O_3 + 2Al -- > 2Fe + Al_2O_3[/tex]
The mole ratio of [tex]Fe_2O_3[/tex] to Al is 1:2.
But 3 moles and 5 moles of reactants respectively started the reaction. Thus, Al is limited in availability and will determine the amount of products that will be produced.
The mole ratio of Al and Fe is 1:1, therefore, a maximum of 5 moles of Fe will be produced from the reaction.
5 moles Fe = 5 x 56 = 280 grams
