A sample of seawater contains 1.3 g of calcium ions in 3,100 kg of solution. what is the calcium ion concentration of this solut

ion in units of ppm?

A unit of ppm has an acronym of parts per million. The equivalent units of ppm is therefore mg/L and mg/kg. So the ppm is:

mass Ca+ = 1.3 g = 1300 mg

 

ppm = 1300 mg / 3100 kg

<span>ppm = 0.42 ppm</span>

Would an opah fish be better suited to live in cold water or warm water? explain why
Kaylis [27]

Don't blame me if you get it wrong i'm a dumb but yet successful student

Warm blood gives deep-sea fish a boost, according to Wegner. The opah's muscles and nervous system likely function faster than an equivalent fish with cold blood. ... This fish, the southern opah, lives in colder waters than the northern opah, so it would be harder to keep warm, Wegner said — but even more beneficial.

Please help with 14-16 <br> Thank you!
Natalka [10]
I don't know about 14, but 15 is (4), because a liquid draws in heat to turn into a gas. 16 is (2), because to turn into a cold solid, something has to release heat.

How many grams of solute are needed to order to prepare 100.00 mL of a 0.1000 M solution of a compound with a molecular weight o
Troyanec [42]

The grams of solute are required.

The mass of solute is 3.5 g

c =  Molarity = 0.1 M

M = Molar mass = 350 g/mol

V = Volume of solution = 100 mL = 0.1 L

n = Number of moles

m = Mass of solute

Molarity is given by

c=\dfrac{n}{V}\\\Rightarrow n=cV\\\Rightarrow n=0.1\times 0.1\\\Rightarrow n=0.01\ \text{moles}

Molar mass is given by

M=\dfrac{m}{n}\\\Rightarrow m=Mn\\\Rightarrow m=350\times 0.01\\\Rightarrow m=3.5\ \text{g}

The mass of solute is 3.5 g

8. Based on the formula, predict whether each of the following compounds is primarily ionic or primarily covalent. a. sodium iod
Lina20 [59]

primarily ionic  include = sodium iodide( NaI) ,   calcium chloride  ( CaCl2)


primarily covalent    include  - Ammonia (NH3) , Methane ( CH4)  and  

                                                   Glucose  (C6H12O6)


Explanation

ionic  bond  is formed  when  there is complete transfer of electron between atoms. It occur  between metal  which  donate electrons and  a  non  metal which accept  electrons.

 for  example  in  formation  of CaCl2,   ca  donate  2 electron to 2  Cl atom, while  2 Cl atom accept the 2  electrons  to form ionic bond.

 Covalent bond  is formed  when two or  more  non  metal  form bond by sharing  electrons pairs.

For  example in NH3   3 pairs of electron are shared.  to form covalent bond.
