Answer:
C₅H₈O₂
Explanation:
methyl methacrylate = 100 amu
6.91g CO₂ = 0.157 moles
2.26g H₂O = 0.125 moles
0.157 ÷ 0.125 = 1.256
{(CO₂)₁.₂₅₆ + (H₂O)₁} × 4 = (CO₂)₅ + (H₂O)₄
C₅H₈O?
C₅ = 60.05 amu H₈ = 8.064 amu
60.05 + 8.064 = 68.114 amu
100 amu - 68.114 amu = 31.886 amu
O = 16 amu
O = 2
Answer:
hey mate here is your answer
First, we have to know the formula of each of the substances:
calcium nitrate: Ca(NO₃)₂
ammonium fluoride: NH4F
calcium fluoride: CaF2
dinitrogen monoxide: N2O
water: H2O
Next, we write the unbalanced reaction. We look at each element and count the number per side. The side with the less number of that element should get a coefficient to balance.
please mark me as a brainliest
C) medium.
The medium of a wave is any substance that carries the wave, or through which the wave travels.Ocean waves are carried by water, sound waves are carried by air, and. the seismic waves of an earthquake are carried by rock and soil.
Answer:
A. the ration is 2 to 3, 2Al + 3H2SO4 has the same balance as 18Al + 3H2SO4
2/3 = 18/27
B. Doesn't need an explanation other than the work you did to balance it.
Answer:
The "kinetic particle theory" explains the properties of solids, liquids and gases. There are energy changes when changes in state occur.
When heat is added to a substance, the molecules and atoms vibrate faster.
As atoms vibrate faster, the space between atoms increases.
The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
