Which properties of grains determine the texture of rocks? Check all that apply. 1. feel
2. pattern
3. color
4. shape
5. size
Multiple answer.

Answers

Answer 1
Answer:

Particles of minerals called grains give the rock its texture. The igneous texture of the rock is not how it feels in your hand, not whether it is rough or glassy.

The shape, size, and arrangement including their color, surface space, and characteristics of a rock's grain determine its texture. Rocks can be finely grained, rough, or soft depending upon their texture.

Properties of grains-

  • Uniform moisture contents
  • High test weight
  • No foreign material
  • The Low percentage of discolored, broken, and damaged kernels.
  • Low breakability
  • High milling quality

Therefore, options 3,4,5 are correct, size, shape, and color determine the texture of color.

Can ir spectroscopy be used to distinguish 2-pentanone from 2-hexanone why or why not

Answers

No

Infrared (IR) Spectroscopy is a set of techniques that involves the analysis of the interaction between infrared light and a molecule. Infrared spectroscopy is mainly used to determine functional groups in molecules and it can also be employed to study and identify chemicals.  

IR spectroscopy cannot be used to distinguish 2-pentanone from 2-hexanone because the two structures have the same functional group. IR spectroscopy can only be used to distinguish molecules that have different functional groups.

Which ratio is equivalent to 18/24 ?
a. B.
c. D.

Answers

A. 5/8 B. 2/3 C. 10/12 D. 3/4

We need to simplify the fraction. Whatever number we use to divide the numerator, should also be the number used to divide the denominator.

18 ÷ 2 =   9
24 ÷ 2 = 12

  9 ÷ 3 = 3
12 ÷ 3 = 4

18 / 24 is equal to 9/12
18 / 24 is equal to 3/4 CHOICE D.

3/4 IS THE SIMPLEST FORM OF THE FRACTION 18/24

Question 5What is the measure of the missing angle?


Triangle with two of its angles measuring 125 degrees and 42 degrees.


42°


125°


13°


Question 5 What is the measure of the missing angle? - 1

Answers

a triangles interior angles always add up to 180 degrees, so you add 125 and 42 and you get 167, then you do 180 minus 167 and you get 13
125 hope this helps :) XOXO
