the answer your looking for is metal
(1) CCl4 (3) C6H12O 6
(2) CH3OH (4) Ca(OH)2
Answer:
150ml .........60 minute
x ........... 1 minute
x = 150ml× 1 minute / 60 minute
x = 2.5ml
Explanation:
it is known that the client receives 150ml of the solution for over an hour.convert the hour into minutes,then we do not know how much liquid a client receives in a minute. we cross multiple the values to get the value in ml. for every one minute the client receives 2.5ml of the fluid.
c. Fluorite
b. Topaz
d. Gypsum
Gypsum
The hardness of minerals or substances is measured qualitatively using Mohs Scale. In this scale the hardness is measured qualitatively by characterizing the resistance shown by one substance when rubbed against second substance. Therefore, greater points are given to those substances which are capable of making scratches on other substances. The Mohs Scale of given compounds is as follow,
Diamond 10
Fluorite 4
Topaz 8
Gypsum 1.5 to 2
While the hardness value of Fingernail is 2 to 2.5. Hence, this value is close to Mohs scale hardness value of Gypsum therefore, gypsum is the correct answer.
40
20Ca
The symbol for an isotope of Calcium-42 corresponding to the isotope notation is
Isotopes are atoms of the same element that have the same number of protons (atomic number) but different numbers of neutrons (mass number).
