Cl2 +2e- —> 2Cl-

1 answer:

7 0

When two electrons are added to chlorine has, Cl2, each atom of Cl will receive one electron. Hence, the atoms becomes ions having a negative charge, Cl-

Ions are atoms or group of atoms possessing an electrical charge which may be positive or negative.

Negatively charged ions are formed when atoms accept or gain electrons. The negative charge is because there are more electrons than protons in the atom.

Negatively charged ions are usually formed by non-metals. For example, chlorine gas accepts two electrons to become 2 Cl-

Cl2 + 2e- ----> 2 Cl-

Therefore, when two electrons are added to chlorine has, Cl2, each atom of Cl will receive one electron. Hence, the atoms becomes ions having a negative charge, Cl-

<h2>GREETINGS!</h2><h2>_____________________________________</h2><h3>Answer:</h3>

ITS $C_{4}H_{10}$ AND $C_{5}H_{12}$

<h2>_____________________________________</h2><h3><u>GENERAL FORMULA OF ALKANE</u></h3><h3> $C_{n}H_{2n+2}$ </h3>

Where n is the number of CARBONS

By using the General Formula of Alkanes having 4 carbon atoms is

$C_{4}H_{2x4+2}$

$C_{4}H_{10}$

By using the General Formula of Alkanes having 5 carbon atoms is

$C_{5}H_{2x5+2}$

$C_{5}H_{12}$

IF YOU USE THE SAME FORMULA FOR THE OTHER TWO OPTIONS THE OUTCOME WILL NOT BE AS SAME AS GIVEN IN THE QUESTION SO THOSE TWO ARE CAN NOT BE OUR ANSWER

Citric acid is one component of some soft drinks. Suppose that 8 L of solution are made from 0.24 g of citric acid, C6H8O7. What

stealth61 [152]

Answer:

The correct answer is 0.15 × 10⁻³ M.

Explanation:

C₆H₈O₇ is the molecular formula of citric acid. The mass of the one mole of the substance that comprise Avogadro's no of molecules is termed as the molar mass of the substance.

The molar mass of the citric acid (C₆H₈O₇) will be,

6 × atomic mass of carbon + 8 × atomic mass of hydrogen + 7 × atomic mass of oxygen = 6×12 + 8×1 + 7×16 = 192. Thus, the molar mass of citric acid is 192 g/mol.

The value of the solution given in the question is 8 L.

The mass of citric acid given is 0.24 g or 240 mg, which can also be written as 240/1000 g or 240 × 10⁻³ g.

The number of moles can be calculated by using the formula = mass / molar mass. Thus, by putting the values we get,

= 240 × 10⁻³ g / 192 g/mol

= 1.25 × 10⁻³ mol

The number of moles of the solute present in the 1 liter of the solution is termed as the molarity of the solution. The formula of molarity or M is,

= no of moles of solute / volume of solution in L

Now putting the values we get,

= 1.25 × 10⁻³ mol / 8 L

= 0.156 × 10⁻³ M

Hence, the molarity of citric acid in the given solution is 0.15 × 10⁻³ M

What's the structure of Cl2O? Is it polar or non-polar?

lisabon 2012 [21]

Answer: C) Bent or angular, polar
Explanation:
The central atom oxygen has two lone pairs and two bond pairs in . The number of electron pairs are 4, that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral. But as there are two lone pair of atoms around the central oxygen atom, repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent shape.
The compound is polar as the net dipole moment of oxygen - fluoride bonds do not cancel each other out.

Help i’ll give u points

Bond [772]

Answer:

60ug

Explanation:

If it has experienced two half lives, that means it has been halved twice. in that case, to undo it, just multiply it by two twice. 0.15ug * 2 = 0.30ug. 0.30ug * 2 = 0.60ug. Hope this helps.
