A pharmacist mixed some 10%-saline solution with some 15%-saline solution obtain 100 mL of a 12%-saline solution. How much of the 10-saline solution did the pharmacist use in the mixture

Answers

Answer:

10%-saline solution = 60mL

15%-saline solution = 40mL

Explanation:

Let

10%-saline solution = x

15%-saline solution = y

x + y = 100

0.1x + 0.15y = 100*0.12

x + y = 100 (1)

0.1x + 0.15y = 12 (2)

from (1)

x = 100 - y

Substitute x = 100 - y into

0.1x + 0.15y = 12

0.1(100 - y) + 0.15y = 12

10 - 0.1y + 0.15y = 12

- 0.1y + 0.15y = 12 - 10

0.05y = 2

y = 2 / 0.05

y = 40mL

Substitute y = 40 into

x + y = 100

x + 40 = 100

x = 100 - 40

x = 60mL

10%-saline solution = 60mL

15%-saline solution = 40mL

Answers

Answer:

Combination or synthesis

Explanation:

The given reaction is:

            6Li +  N₂ → 2 Li₃N

This reaction is a synthesis or combination reaction. 6 moles of Li combines with nitrogen gas to produce 2 moles of  Li₃N.

In a synthesis reaction, two substances combines together to give singular product. The formation of compounds from the union of the constituent elements falls into this category of reaction.

Tony sets up an experiment inside his classroom. He spaces 5 plants at equal distances along a straight line, with the first plant directly in front of a window and the last plant 10 meters (m) away from the window. He gives them equal access to air and water and then monitors the amount of gas each plant releases.
Which gas is Tony monitoring and what trend is he most likely to see in the data he collects?

He is monitoring oxygen. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.

He is monitoring carbon dioxide. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.

He is monitoring oxygen. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.

He is monitoring carbon dioxide. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.

b. 0.2046 g Ne
c. 8.333 g Ne
d. 4.130 g Ne

Answers

Answer:

Mass = 83.33 g

Explanation:

Given data:

Number of atoms of neon = 2.486×10²⁴

Mass of neon = ?

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

2.486×10²⁴ × 1 mol / 6.022 × 10²³ atoms

0.413×10¹ mol

4.13 mol

Mass of neon:

Mass = number of moles × molar mass

Mass = 4.13 mol × 20.18 g/mol

Mass = 83.33 g

When added to ice, salt first dissolves in the film of liquid water that is always present on the surface, thereby lowering its freezing point below the ices temperature. Ice in contact with salty water therefore melts, creating more liquid water, which dissolves more salt, thereby causing more ice to melt, and so on

This might not seem 1unusual. My mother hates cats. Perhaps hate is 2 to strong a word. She definitely fears them. She cant help it. I guess 3 one could say this fear is inherited. Her mother, her three aunts, and her grandmother all share this phobia. Nonetheless, the kitten is a beloved member of our family now. 4 Heres the story:5 One summer morning in August, Mom and Aunt Fran went to the school track to walk. Off in the distance they heard a noise that sounded like a baby screaming. It was coming from a dumpster near the cafeteria. Alarmed, they moved closer to investigate. The wailing grew louder. Aunt Fran gasped when she saw the tiny head of a kitten trapped in a small opening in the bottom of the dumpster. 6 Its body could not make it through the hole. Hopelessly trapped, 7 we saw that the creature continued to shriek. The women looked around for a mother 8 cat. None in sight.They realized that the summer heat would be unbearable by midday. Quelling their fears, they rattled off options: call for someone to come help; push the kittens head back into the dumpster; 9pulling the rest of its body out of the opening; leave and hope someone who is not afraid finds the kitten in time; ignore the screeching and get walking.10 Mom picked up a discarded jacket and covered the kittens head. She pulled gently, then firmly, but that kittens body was not coming out. So now it was Aunt Frans turn. After several attempts she pushed the kittens head back into the dumpster. Maternal instincts kicked in and my mother climbed into the dumpster. 11 Cautiously, she picked up the kitten.Aunt Fran 13 said we oughtta name her D.D. for dumpster diver, but we were set on Lily. After our trip with the kitty to the vet, we learned that Lily is a boy! Of course we plan to change his name. We havent convinced Mom that we need a friend for the kitty, but I am optimistic. I like the name Frank, but my sister is pushing for Harold. Whatever name we choose, I am glad that mom and Aunt Fran were able to face their fears.What traditional theme is conveyed through this story?Question 19 options:The importance of family petsThe importance of sistersThe importance of overcoming fearsThe importance of family Adelberg Company has two products: A and B. The annual production and sales of Product A is 1,900 units and of Product B is 1,300 units.
