Answer:

the degree to which they decrease CNS activity

Explanation:

Drugs can be classified as;

✓hallucinogens, example is (LSD)

✓ stimulants, example is (cocaine)

✓opium-related painkillers example is (heroin)

✓depressants

Depressants can be regarded as medicines, that lowers neurotransmission levels, that is depressing or reducing arousal or stimulation as regards to various areas of the brain. these could be tranquilizers, as well as hypnotics and

sedatives. They are drugs used in slowing brain activity, therefore, making them useful when treating anxiety, sleep disorders, panic and acute stress reactions.

Example of Depressants are;

✓Xanax

✓Halcion

✓Klonopin

✓Librium

It should be noted that Depressants are often classified according to the degree to which they decrease central nervous system (CNS) activity.

A scientist hypothesizes that fertilizer containing 10 percent nitrogen will produce tomato plants with more leaves and blossoms
gogolik [260]

The correct answer is - A- Amount of nitrogen in fertilizer.

The independent variable, in mathematical terms, is the variable whose variation is not dependent on the variations of the another variables.

In this case, the independent variable will be the amount of nitrogen in the fertilizer, as it is not dependent on any other variable. Also, apart from not being dependent on other variables, it is a variable on which the other variables are dependent, which in this case will be the amount of leaves and the amount of blossoms on the tomato plant.

The anticancer drug Platinol (cisplatin), Pt(NH3)2Cl2, reacts with the cancer cell's DNA and interferes with its growth. (a) Wha
USPshnik [31]

Answer:

(a) = 65.018% (b) = 1.807,83 grams

Explanation:

(a)

The mass % of platinum (pt) in platinol can be obtained applying the general percentage formula (portion of interest / total), in this case the platinol its composed of a single platinum (Pt) mole with molecular weight of 195.088 g/mol, two nitrogen (N)  mole of 28.012 g/mole each. six hydrogen (H) mole of 1.007 g/m and two chlorine (Cl) of 35.453 g/mole

N= 14.006 g/mole x 2 = 28.012

H= 1.0078 g/mole x 6 = 6.046

Cl= 35.453 g/mole x 2 = 70.906

Pt= 195. 088 g/mole x 1 = 195.088

the molecular weight of platinol its = 300.052g

% of Pt in platinol its = ((195.088 g/mole) /(300.052 g/mole))* 100= 65.018%

(b)

Assumption: 851/9 its in fact 851 $/gram

to know how many grams of Platinum can be bought it's necessary to divided the total money between the price of platinum, knowing how many grams can be bought and knowing the percentage of platinum in platinol, it's possible to know how many grams of platinol can be made from $1.00 million

grams of platinum $1'000.000/(851$/g) = 1.175,09 grams of Pt

grams of platinol =

1.175,09 grams of pt/ 0.65018 (grams of pt/grams of platinol)

grams of platinol = 1.807,83 grams of platinol
