Answer:
2HNO3+ Ba(OH)2 = Ba(NO3)2 + 2H2O
H3PO4 + Ca(OH)2 = Ca3(PO4)2 + 6H2O

Answer:
Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the "universal solvent" because it dissolves more substances than any other liquid. This is important to every living thing on earth.
From Faraday's 1st law of electrolysis,
Total electricity passed into system = Q = IT = 250 X 24 X 60 X 60
= 2.16 X 10^7 C
We know that, 96500 C = 1 F
∴ 2.16 X 10^7 C = <span>223.8 F
</span>
Now, number of moles of<span> MnO2 deposited = 223.8/2=111.9
</span>
Finally, 1 mole of MnO2 ≡ 86.94 g
∴ 111.9 mole of MnO2 ≡ 111.9 X 86.94 = 9728 g
Thus, <span>mass of MnO2 that will be deposited at anode = 9728 g</span>
Transverse wave:
⇨- the way the wave is moving
⟶- Medium - the material it is traveling through
冖- Wavelength - the distance from crest to crest
C - Crest - the highest point on a wave
T - trough - the lowest part on a wave
↕️ - Amplitude - the distance from rest to crest
ྊ - (tinfoil)Wave
Description:
In the beginning of the wave the wavelength is short and the frequency is high so is the energy.and the amplitude is low *i believe* And after the mark of T shown on the image the wavelength is long and the frequency is low and so is the energy and the amplitude is high *i believe*.Amplitude and wavelength are both measures of distance.
Longitudinal/Compressional Wave:
KEYS:
⟶-medium - the material it is traveling through
⇨-way the wave is moving
冖-wavelength - the distance from crest to crest
R -Rarefaction - the opposite of compression
C-Compression - particles are closest together
