Answer:
Waves carry energy from place to place.
Explanation:
Some waves are used for mainly communication and phone signals. They help people get internet in the middle of nowhere if you are near an energy wave.
Answer:
Explanation:
2H₂O₂ ⟶ 2H₂O + O₂
A catalyst is a substance that speeds up a reaction but can be recovered unchanged at the end.
Thus, at the end of the reaction I would expect to find H₂O and MnO₂ in the container.
Water is not listed in any of the options, so I will have to choose .
A, B, and D are wrong. They are not reactants, products, or catalysts.
Answer:
We see that the mass number of this atom is 195. And then, atomic number, the number of protons, is 78. 195 minus 78 is equal to 117. This then is the number of neutrons in this platinum atom.
Please allow me to know if this helped with a thank you!

if you are talking about the climate change of today as in the heat your answer would be ,because the green house gases are trapping in the heat and reflecting it back down it disrupts the temperature everywhere. so the hot weather will become even HOTTER the cold weather will become warmer of come to late ,and the places such as Greenland and Antarctica which are covered in snow will start to melt making the whole globe more hot year by year
0.3 moles of lithium chloride (LiCI) reacted to produce 24.68 grams of lithium nitrate (LiNO3).
Explanation:
Balanced equation for the reaction is:
2LiCl + Pb(NO3)2 ⇒2 LiNO3 + PbCl2
Data given:
mass of LiNO3 produced = 24.68 grams
moles of LiCl reacted= ?
atomic mass of 1 mole of LiNO3 = 68.946 Grams
Number of moles =
putting the values in the above equation:
= 0.3 moles
from the reaction,
2 moles of LiCl reacted to form 2 moles of LiNO3
so, x moles of LiCl reacted to form 0.3 moles of LiNO3
=
x = 0.3 moles of LiCl will react to form 0.3 moles of LiNO3.
