1. Which of the following statements describe cations? Select all that apply.
Positively charged ions.
Negatively charged ions.
They have lost electrons.
They have gained electrons.

Answers

Hey :)

Cations are positively charged ions and they have lost electrons

Hope this helps!

Ions can be made by single element or covalently bonded group of elements. The covalently bonded group of elements is called polyatomic ions or polyatomic atoms. The correct option are option A,C.

What is Ions?

Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.

Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state.

Therefore the correct option are option A,C.

To prepare 380 mL of 0.500 M NaCl (MW = 58.5 g/mol), how many grams of sodium chloride is required?

Answers

This answer did not come from me but here you go!
44 g NaCl
Explanation:
The problem provides you with the molarity and volume of the target solution, so your first step here will be to use this information to figure out how many moles of sodium chloride,
NaCl
, it must contain.
Once you know that, use the compound's molar mass to convert the number of moles to grams.
So, molarity is defined as the number of moles of solute per liter of solution. In your case, a
0.77 M
solution will contain
0.77
moles of sodium chloride, your solute, in
1.0 L
of solution.
Your target solution has a volume of

11.12 grams of sodium chloride is required to prepare 380 mL of 0.500 M NaCl (MW = 58.5 g/mol).

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass.

However, the number of moles of sodium chloride must first be calculated by multiplying the molarity by its volume.

Molarity = no. of moles ÷ volume

0.500M = n ÷ 0.380L

n = 0.5 × 0.380

n = 0.19mol

mass of NaCl = 58.5g/mol × 0.19mol

Mass of NaCl = 11.12g

Therefore, 11.12 grams of sodium chloride is required to prepare 380 mL of 0.500 M NaCl (MW = 58.5 g/mol).

How much ice could be melted at 0​°​C if 5200 joules of heat were added?

Answers

Answer:

0.02kg

Explanation:

Given parameters:

Amount of heat  = 5200J

Unknown:

Mass of ice that would be melted at 0°C = ?

Solution:

To solve this problem, use the expression below;

        H  = mL

H is the heat

m is the mass

L is the latent heat of fusion of ice  =  3.33 x 10⁵ J/kg.

 Insert the parameters and solve for m;

           5200  = m x 3.3 x 10⁵

             m  = [tex]\frac{5200}{3.33 x 10^{5} }[/tex]   = 0.02kg

     

WHAT PROBLEMS DID PRESIDENT JEFFERSON HAVE WITH TRIPOLI AND HOW DID HE SOLVE THEM

Answers

Answer:

Although Thomas Jefferson came to power determined to limit the reach of the federal government, foreign affairs dominated his presidency and pushed him toward Federalist policies that greatly contrasted with his political philosophy. The first foreign episode involved Jefferson's war with the Barbary pirates. For the previous century or so, Western nations had paid bribes to the Barbary states, which would later become Morocco, Algeria, Tunis, and Tripolitania, to keep them from harassing American and merchant ships
