All elements can be classified as metals, metalloids, or nonmetals
Answer:
The texture of a rock is a result of its mineral composition
Most rocks contain more than one type of sediment
Explanation:
Explanation:
Mass ratio C : H : N = 27.3 : 9.10 : 63.6
Mole ratio C : H : N = 27.3/12: 9.10/1 : 63.6/14
( Divide the mass ratio by their molar masses to find the ratio between moles)
Mole ratio = 2.275 : 9.10 : 4.54
= 2.275/2.275 : 9.10/2.275 : 4.54/2.275
= 1 : 4 : 2
Answer is CH4N2
The cathode ray tube is connected to a vacuum pump because the vacuum pump is used to draw air out of the ray tube before it closes/sealed. Hope this helps.
