Answer:

Mass of Nacl = 4.92 gram (Approx)

Explanation:

Given:

Hydrochloric acid = 3.3 g

Sodium hydroxide = 5 g

Computation:

Hcl + NaoH ⇒ Nacl + H₂O

Number of mole of Hcl = 3.3 / 36.46 = 0.0905 moles

Number of mole of NaoH = 5 / 40 = 0.125 moles

We, know that number of moles in Hcl is less then number of mole in NaoH

So,

Number of mole of Hcl = Number of mole of Nacl

So,

Mass of Nacl = Number of mole of Nacl × Molar mass of Nacl

Mass of Nacl = 0.0905 × 54.4

Mass of Nacl = 4.92 gram (Approx)

Write the formula for calcium chloride. Explain how you determined this formula
hichkok12 [17]

Calcium forms an ion with a positive 2 charge and chlorine forms an ion with a negative one charg, so the formula is <span>CaC<span>l2</span></span>

Group 1 metals and group 2 metals form positive ions by losing 1 and 2 electrons respectively. Non-metals in group 17 gain 1, group 16 gain 2 and group 15 gain 3. Elements which lose electrons form positive ions while elements that gain electrons form negative ions. 

To write a formula, you must balance charges so the overall charge is zero. A simple way to do this is to swap the # of the ion's charge and make it the subscript of the other ion. However, leave off the number 1 and reduce to lowest whole number ratio.

What NaCl NaCl concentration results when 249 mL 249 mL of a 0.850 M 0.850 M NaCl NaCl solution is mixed with 667 mL 667 mL of a
tamaranim1 [39]

Answer:

The answer to your question is 0.54M

Explanation:

Data

Final concentration = ?

Concentration 1 = 0.850 M

Volume 1 = 249 ml = 0.249 l

Concentration 2 = 0.420 M

Volume 2 = 0.667 M

Process

1.- Calculate the number of moles in both solutions

Number of moles 1 = Molarity 1 x Volume 1

                               = 0.850 x 0.249

                               = 0.212

Number of moles 2 = Molarity 2 x Volume 2

                                = 0.420 x 0.667

                                = 0.280

Total number of moles =  0.212 + 0.280

                                      = 0.492

2.-Calculate the final volume

Final volume = Volume 1 + Volume 2

Final volume = 0.249 + 0.667

                      = 0.916 l

3.- Calculate Molarity

Molarity = 0.492 / 0.916

Molarity = 0.54

How is bacteria on mars counted as life but a heartbeat on earth not?
Sever21 [200]

Answer:

It is considered life, but that doesn’t have to do much with abortion.

We kill things all the time. Unless you are vegetarian, lots of animals are killed to give you meat. Even if you are, you’ll probably swat a mosquito that’s trying to bite you. And what about the bacteria inside your body that are constantly killed to keep you healthy?

The question is how much this life is worth. This becomes more a question of ethics, but I think we can all agree a human life is worth a lot. So killing humans is wrong. What about somewhat intelligent animals? Well, killing them just for the fun of it or because you can is wrong as well I think.Most people think that’s okay, although some people will disagree and become vegetarians.

Insect life is worth less, and killing an insect is seen by most people as okay as long as you have even a small reason for it (like being irritated by a buzzing fly).

And all the way on the bottom are bacteria. They are not conscious, even though alive.

Sorry about the first answer. I didn't look at the question carefully since I wasn't wearing my glasses.

If this doesn't help than I'm sorry.
