Answer:
I only know number one answer hope it is helpful
Conduction is the transfer of heat through stationary matter by physical contact. (The matter is stationary on a macroscopic scale—we know there is thermal motion of the atoms and molecules at any temperature above absolute zero.) Heat transferred from an electric stove to the bottom of a pot is an example of conduction.
Some materials conduct thermal energy faster than others. For example, the pillow in your room may the same temperature as the metal doorknob, but the doorknob feels cooler to the touch. In general, good conductors of electricity (metals like copper, aluminum, gold, and silver) are also good heat conductors, whereas insulators of electricity (wood, plastic, and rubber) are poor heat conductors.
Mechanical weathering breaks rocks into many pieces creating more surface area for chemical weathering
<u>Satelites</u> are a type of space technology utilizes the electromagnetic spectrum to collect information.
Explanation:
Depending on the electromagnetic spectrum that the satellite is designed for, it can be utilized for a certain scientific function. The Hubble Telescope, for example, is designed to perceive the visible light spectrum of electromagnetic radiation to provide the beautiful pictures of space we see today. Some satellites that orbit teh earth are sensitive to infra-red radiation and are used to monitor earth’s atmospheric and ocean temperatures. Some satellites are designed for X-rays and gamma rays and are used to search for supernovae.
Can u repost with answer choices?
Answer:
C6H6
Explanation:
We can obtain the molecular formula from the empirical formula.
What we need do here is:
(CH)n = 78
The n shows the multiples of both element present in the actual compound. It can be seen that carbon and hydrogen have the same element ratio here. We then use the atomic masses of both elements to get the value of n. The atomic mass of carbon is 12 a.m.u while the atomic mass of hydrogen is 1 a.m.u
(1 + 12)n = 78
13n = 78
n = 78/13 = 6
The molecular formula is
(CH)n = (CH)6 = C6H6
