Answer:NASA's Lunar Atmosphere and Dust Environment probe, for instance, orbits the moon and collects information about its atmosphere and surface. This important data can help scientists learn more about moons, asteroids and other objects in the solar system.
Explanation:
Silicone is most similar to carbon.
hope this helps; and good luck.
Explanation:
Electromagnetic wave Wavelength
(1) Microwave = 1 m to 1 mm = 
to 
(2) Ultraviolet = 10 nm to 400 nm
(3) Radio waves = 1 mm to 100 km = to 
(4) Infrared = 700 nm to 1 mm
(5) X-ray = 0.01 nm to 10 nm
(6) Visible = 400 nm t0 700 nm
a) In order of increasing wavelength:
: 5 < 2 < 6 < 4 < 1 < 3
b) Frequency of the electromagnetic wave given as:
= frequency
= Wavelength
c = speed of light
So, the increasing order of frequency:
: 3 < 1 < 4 < 6 < 2 < 5
c) Energy(E) of the electromagnetic wave is given by Planck's equation :
So, the increasing order of energy:
: 3 < 1 < 4 < 6 < 2 < 5
Answer:
Two moles of HC2H3O2 react with one mole of Ca(OH)2 to produce one mole of calcium acetate and two moles of water.
Explanation:
HC2H3O2 is Acetic acid that can also be represented as (CH3COOH).
when Ca(OH)2 reacts with Acetic acid the product formed will be Calcium acetate and water
Chemically the reaction can be represented as
2CH
3
COOH + Ca(OH)
2 → Ca(CH
3
COO)
2 + 2H
2
O
Two moles of CH3COOH react with one mole of Ca(OH)2 to produce one mole of Ca(CH3COO)2 and two moles of H2O.
Answer:
5)HOCH2CH2OH
Explanation:
This is also known as ethylene glycol. An increase in hydrogen bonds of a compound means an increase in the viscosity. Hydrogen bonds occur as a result of bonding with electronegative elements such as Oxygen, Nitrogen etc.
The compounds with the highest amount of Hydrogen bond represents the one with the highest viscosity which is B) HOCH2CH2OH
