Answer:
The heterogeneous mixture that has very small dispersed particles and stays mixed for a long time is colloid. Because colloid has particles that are small enough to suspended but are as large that they can scatter light.
<span>has four valence electrons in its outermost energy level.
An organic compound in which a carbonyl group is bonded to two different carbon atoms is a(n) ketone.
All of the following release carbon into the atmosphere except the
sedimentation of dead organisms.</span>
2KCl = 2K + Cl₂
v(K)=69.9 ml
p(K)=1.78 g/ml
M(K)=39.1 g/mol
M(KCl)=74.6 g/mol
1) m(K)=v(K)p(K)
2) m(KCl)=M(KCl)m(K)/M(K)
3) m(KCl)=M(KCl)v(K)p(K)/M(K)
m(KCl)=74.6*69.9*1.78/39.1=237.39 g
Answer
Ultraviolet
Explanation
The types of radiation and their wavelength are:
Gamma < 10⁻¹² m
X-rays 1 nm - 1 pm
Ultraviolet 400 nm - 1 nm
Visible 750 nm - 400 nm
Near-infrared 2.5 μm - 750 nm
Infrared 25 μm - 2.5 μm
Microwaves 1 mm - 25 μm
Radio waves > 1 mm
Hence, the given wavelength of 2.86 X 10⁻⁸ m corresponds to Ultraviolet.
