I suspect this question should read "How long does a red blood cell live." A red blood cell lives for between 100 and 120 days. It takes 7 days for a new red blood cell to develop from stem cells. Stem cells are similar to base cells. They can also be seen as a general template from which specialized cells are made. Stem cells can be taken from a newborn baby's umbilical chord or extracted from an adult blood donor's blood.This
Answer:
2.03
Explanation:
Let's <u>assume we have 1 L of the solution</u>:
- There would be 2.07 ethylene glycol moles.
- The solution would weigh (1000 mL * 1.02 g/mL) = 1020 g.
With that information we can <u>calculate the molality</u>:
- molality = moles of solute / kg of solvent
- molality = 2.07 moles / (1020 ÷ 1000) = 2.03 m
Keep in mind that this is only an estimate, as we used the kg of the solution and not of the solvent.
- An acid will have the suffix “–ic acid” at the end of its name when the negative ion has a suffix -ide.
- An acid will have the suffix “–ous acid” at the end of its name when the negative ion has a suffix -ite.
<h3>What is an Acid?</h3>
This is defined as a chemical substance which can react with a base to form a salt in a reaction.
The appropriate acid suffixes and conditions is however correctly given above.

Answer:
New temperature = 546 K
Explanation:
Given that,
Initial volume, V = 200 L
Initial temperature, T = 273 K
We need to find the new temperature if the volume is doubled.
The relation between temperature and volume is direction. If volume is doubled, it means the temperature gets also doubled.
New temperature of the gas = 2(273) = 546 K
