Answer:
Rabbbits are scared so if there is an increase in the snake population they would try and hide and run from it bur hawks also prey on rabbits but not every hawk so Im going with bthe snake answer .
Explanation:
According to Dalton's law of partial pressure
The total pressure of a mixture of ideal gases is sum of the partial pressures of each gas present in the mixture
So if we know the partial pressure of all the gases we can determine the total pressure of the mxiture by adding all of them.
Thus
Ptotal = PCl2 + PF2 + PHe
Thus
Partial pressure of helium = 205 - ( 89 + 15) = 101 kPa
Nickel (Ni) has the charge as +3 while oxygen (O) has -2. Hence, the chemical formula for the nickel (iii) oxide is Ni₂O₃.
molar mass of Ni = 58.69 g/mol
molar mass of O = <span>15.99 g/mol
number of Ni atoms in </span>Ni₂O₃ = 2
Molar mass of Ni in Ni₂O₃ = 2 x 58.69 g/mol = 117.38 g/mol
number of O atoms in Ni₂O₃ = 3
Molar mass of O in Ni₂O₃ = 3 x 15.99 g/mol = 47.97 g/mol
Hence, molar mass of compound = 117.38 g/mol + 47.97 g/mol
= 165.35 g/mol
=<span> 165.4 g/mol</span>
Answer:
Ba3(PO4)2
Explanation:
since it's created by giving or taking electrons
Answer:
formation reaction.
Explanation:
Since the aluminum bromide produced in this reaction is formed from elements in their standard states, this is an example of a formation reaction.
