because the government is lying to us about the moon and everything in space.
Answer:
There is little if any, space left between its adjacent molecules.
Good luck!
Answer:
0.169 mole of Al
Explanation:
We'll begin by by calculating the number of mole in 45 gof AlBr₃. This can be obtained as follow:
Mass of AlBr₃ = 45 g
Molar mass of AlBr₃ = 27 + (3×80)
= 27 + 240
= 267 g/mol
Mole of AlBr₃ =?
Mole = mass /molar mass
Mole of AlBr₃ = 45 / 267
Mole of AlBr₃ = 0.169 mole
Finally, we shall determine the number of mole of Al needed to produce 45 g (i.e 0.169 mole) of AlBr₃. This can be obtained as illustrated below:
2Al + 3Br₂ —> 2AlBr₃
From the balanced equation above,
2 moles of Al reacted to produce 2 moles of AlBr₃.
Therefore, 0.169 mole of Al will also react to produce 0.169 mole of AlBr₃.
Thus, 0.169 mole of Al is needed for the reaction.
Answer:
B
Explanation:
This is because conductivity depends on the mobility of electrons.
Hello there! It sounds like she intends to pursue a career in Genetic engineering
Genetic engineering is "the deliberate modification of the characteristics of an organism by manipulating its genetic material". Since Yvonne is interested in the possibility of modifying human DNA, this seems to be the perfect fit since it involves modifying DNA.
Hope this helps, have a great day!
