Answer:
An exact number is a value that is known with complete certainty. Like for Examples of exact numbers are counted numbers of objects or certain unit conversions. For example, there are exactly 3 feet in 1 yard. There are exactly 12 eggs in a dozen. A class may contain exactly 25 students.
Explanation:
Hope this helps.
Have a good night ma´am/sir.
Be safe!
When the pH falls below 7.35, <span>a state of acidosis exists.
</span>The normal pH in the mammals arterial blood is between 7.35 and 7.50, so a<span>cidosis occurs when arterial </span>pH falls below 7.35. Acidosis is a process causing increased acidity (<span>increased </span>hydrogen ion or proton H⁺ concentration) in the blood and other body tissues.
Alkalosis<span> occurs at a pH over 7.45.</span>
Answer:
oxygen
Explanation:
because the 2nd shell is not complete which is suppose to be 8 and since oxygen is 8 it first shell is 2 which is complete and the second shell which is 6 is not complete because we all know that 2+6=8 but the standard shell is
K-2
L-8
M-8
Answer:
Explanation:
Data:
50/50 ethylene glycol (EG):water
V = 4.70 gal
ρ(EG) = 1.11 g/mL
ρ(water) = 0.988 g/mL
Calculations:
The formula for the boiling point elevation ΔTb is
i is the van’t Hoff factor — the number of moles of particles you get from 1 mol of solute. For EG, i = 1.
1. Moles of EG
2. Kilograms of water
3. Molal concentration of EG
4. Increase in boiling point
5. Boiling point
Nope...... life basis is organics and CARBON is backbone of that
