<u>Answer:</u> The salinity of ocean water is 34 ppt.

<u>Explanation:</u>

Salinity is defined as the number of grams of salts present per kilogram of seawater. It is expressed in parts per thousand.

The formula used to calculate the salinity of ocean water or sea water is:

\text{ Parts per thousand}=\frac{\text{Mass of salts}}{\text{Mass of sea water}}\times 1000

We are given:

Mass of salts = 17 g

Mass of sea water = 500 g

Putting values in above equation, we get:

\text{ Parts per thousand}=\frac{17g}{500g}\times 1000\\\\\text{ Parts per thousand}=34

Hence, the salinity of ocean water is 34 ppt.

A liquid occupies 321ml and has a mass of 376g. what is the density of the liquid?​
oee [108]

Answer:

The density of the liquid is 1.153 grams/ml.

Explanation:

You have to use the fomula of density

density = mass/volume ⇒ density = 376 grams/321 ml ⇒

density = 1.153 grams/ml.

A piece of balsa wood has a mass of 15.196 g and a volume of 0.1266 L. What is the density in g/mL?
Nataliya [291]
Density = mass / volume

Since the answer must be in g/ml
Convert volume to ml
0.1266 x 1000 = 126.6 ml

15.196 / 126.6

= 0.126 g/ml

The lewis representation above depicts a reaction between hydrogen (blue) and a main-group element from group (red). in this rep
Fed [463]

The question is incomplete, the complete question is;

The Lewis representation above depicts a reaction between hydrogen (blue) and a main-group element from group______ (red).

In this representation, each Y atom needs ______ electron(s) to complete its octet, and gains these electrons by forming______ bond(s) with atoms of H .

There are ______ unshared electron pair(s) and _______bonding electron pair(s) in the product molecule.

The bonds in the product are _________ (Ionic or Covalent)

Answer:

1) 16

2) 2 electrons

3) 2 bonds

4) 2 unshared pairs of electrons

5) 2 bonding pairs of electrons

6) The bonds in the product are covalent

Explanation:

Group sixteen elements have six electrons on their outermost shell. These include two unshared pairs of electrons and two unpaired electrons. These two unpaired electrons can now be covalently bonded to two hydrogen atoms to give H2Y. The compound H2Y has two lone pairs and two bond pairs of electrons.

H2Y can be a general formula for all hydrides of group 16. They are all very similar in structure but gradually differ in physical and chemical properties according to the graduated variation observed down the group.

Consider the equation below. Upper C a upper C upper O subscript 3 (s) double-headed arrow upper C a upper O (s) plus upper C up
stiks02 [169]

Answer:K subscript e q equals StartFraction StartBracket upper C upper O subscript 2 EndBracket StartBracket upper C a upper O EndBracket over StartBracket upper C a upper C upper O subscript 3 EndBracket EndFraction

Explanation: the answer has it's root in Law of mass action which states that; the rate of a chemical reaction is directly proportional to the product of the concentrations of the reactants raised to their respective stoichiometric coefficients.
