Explanation:
For ICl²-, the central iodine atom is bonded to the 2 chlorine atoms and has 3 lone electron pairs.
Altogether it has 5 electron domains, which means it is sp3d hybridized. (C)
Answer:
<u>D) A base.</u>
Explanation:
A base in chemistry is something that is slippery, hence it being a soap.
Answer:
H1 = 63.3 kJ
Explanation:
When the steam at 100C contacts your skin, it is first condensed to water at 100C. The heat involved with this change in state is calculated using the latent heat of vaporization:
Q = ML = (25.0 g)(2.256 kJ/g) = 56.4 kJ
The water at 100C is then cooled to 34C. The heat involved with this temperature change is calculated using the specific heat capacity. (Because a temperature <em>change </em>is used here, it is not necessary to convert °C to K in order for the units to properly cancel)
Q = mcΔt = (25.0 g)(1kg/1000g)(4190Jkg⁻¹K⁻¹)(100C - 34C) = 6913.5 J = 6.9135 kJ
The total heat H1 that is transferred to the skin is the sum of the two heat values above:
H1 = (56.4 kJ) + (6.9135 kJ) = 63.3 kJ
Answer:
Temperature and Pressure
Explanation:
Temperature and pressure cause change in volume.
So any change in volume will alter the ratio of density as given by equation of density.
Density = mass/ volume
Change in volume will alter the ratio.
Kindly mark it branliest if the answer is little bit satisfying.
