6 0

Answer:

403 Seconds in Minutes is about 6 minutes.

Explanation:

Now, because I don't know if you're labeling your 1500 as meters or miles, I'm assuming it's miles.

I'm going to take a gander at your question.

Since you're technically going so fast for some odd reason.

Your answer should most definitely be 403 MPH

2. 5 acids: coffee, lemonade, soda pop, orange juice, vinegar

5bases: ammonia, baking soda, cough medicine, liquid soaps

3. Acids are very common in some of the foods we eat.

Bases have properties that mostly contrast with those acids

4. Acid+Base=H2O+Salt

HCI+NaOH=H2O+NaCI

Explanation:

2. (all those acids are strong (in pH meaning those are weak and don't affect you) (most the bases are very strong like ammonia)

4. Salt means any ionic compound formed from an acid/base reaction

The​ half-life of a certain tranquilizer in the bloodstream is 5050 hours. how long will it take for the drug to decay to 8686​%
Novosadov [1.4K]
Using the exponential decay model; we calculate "k"
We know that "A" is half of A0
A = A0 e^(k× 5050)
A/A0 = e^(5050k)
0.5 = e^(5055k)
In (0.5) = 5055k 
-0.69315 = 5055k
 k = -0.0001371
To calculate how long it will take to decay to 86% of the original mass
0.86 = e^(-0.0001371t)
In (0.86) = -0.0001371t
-0.150823 = -0.0001371 t
 t = 1100 hours

A chlorine atom has a diameter of 175 picometers (pm). Please write the diameter, in metered, in scientific notation.
IrinaVladis [17]
The answer is 1.75 x 10¹⁰ m.
Scientific notation<span> refers to a mathematical expression that is  used to represent a decimal number between 1 and 10 multiplied by ten, or we can say that to write a large numbers using less digits. 
Diameter of chlorine atom = </span><span>175 picometers (pm) 
</span>175 pm = <span>0.000000000175 m
in scientific notation we will write </span>0.000000000175 m as <span>1.75 x 10</span>¹⁰ m
