Answer:
The new volume if the balloon is cooled at constant pressure is 3.98 L
Explanation:
The new volume is calculated using the Charles law formula
that is V1/ T1 = V2/T2 where,
V1 = 4.24 l
T1= 23c into kelvin = 23 +273 =296 K
T2 = 5.00 c into kelvin = 5.00 + 273 = 278 K
V2 = ?
by making V2 subject the subject of the formula by multiplying both side by T2
V2 = V1 xT2/ T1
V2 = (4.24 L x 278 K) / 296 k = 3.98 L
2H3PO4 + 3Ca(OH)2 ➡ Ca3(PO4)2 + 6H2O.
Hence salt formed is Ca3(PO4)2.
Hope this helps, have a nice day!
Answer:
The number of electron domains in a molecule or ion is the number of bonds (double and triple bonds count as one domain) plus the number of nonbonding (lone) electron pairs.
Explanation:
The order of increasing energy is red, yellow, and blue
In physics for a given wave function, the wavelength is defined as the distance between two consecutive points in the waveform. Light is considered a wave and a particle. White light can split into colors of different wavelengths.
The wavelength of visible light ranges from 300 to 700 nm comprising the color VIBGYOR. Wavelength is calculated by the formula velocity divided by the frequency.
If the frequency of the given form is high, then the energy is also high.

Rank the following photons in terms of increasing energy: (a) blue (λ = 453 nm); (b) red (λ = 660 nm); (c) yellow (λ = 595 nm).
As the frequency is inversely proportional to the wavelength, the energy is also inversely proportional. A higher wavelength will have lower energy.
