How Many Protons, Neutrons, And Electrons Does 35/17 Cl ^ 1- Have?

Answer 2

The number of protons in Cl-35 is 17 and the number of neutrons is 18. The number of Cl is 17 whereas the chloride ion Cl⁻ have 18 electrons.

What is chlorine?

Chlorine is 17th element in periodic table. Cl is includes in the 17th group of p -block. Cl contains 7 valence electrons and it needs one more electron to attain complete configuration. It is highly electronegative and will easily gain an electron to achieve octet.

Atoms in neutral state have equal number of electrons and protons and this number is equal to the atomic number. The mass number is the sum of number of protins and neutrons.

The atomic number of Cl is 17. Hence the number of protons is 17 and the mass number is 35. So that number of neutrons is 35 - 7 =18. When Cl gains an electron it forms the anion Cl⁻. Hence, the number of electrons in Cl⁻ is 18.

Answer:

4. b 5.C

Explanation:

Photosynthesis makes sugar for plants and sunlight is the energy used to convert CO2 and water into glucose

The product of the process of photosynthesis is sugar and the energy to dive the process of photosynthesis comes from sunlight.

What is photosynthesis?

Photosynthesis is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.

Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Option A is correct✔

A certain first-row transition metal ion forms many different colored solutions. When four coordination compounds of this metal, each having the same coordination number, are dissolved in water, the colors of the solutions are red, yellow, green, and blue. Further experiments reveal that two of the complex ions are paramagnetic with four unpaired electrons and the other two are diamagnetic. What can be deduced from this information about the four coordination compounds

Answers

Answer:

See explanation

Explanation:

From the analysis we have in the question, we must look towards a first row transition metal ion having a d^6 configuration because it yields a paramagnetic complex having four unpaired electrons and a diamagnetic complex having no unpaired electrons.

We have two possible candidates in mind, Fe^2+ and Co^3+. However, Fe^2+ does not form as many coloured complexes as stated in the question so we have to eliminate that option.

We are now left with only Co^3+. Various ligands are going to cause these various colours of Co^3+ to appear in solution.

Hence, we can deduce from all these that the nature of ligands determines the colour of the complex . Don't forget that the colour of a complex arises from crystal field splitting.

For the following reaction, calculate how many moles of each product are formed when 4.05 g of water is used.

2 H2O → 2 H2 +02

Answers

Answer:

A. 0.225 mole of H₂

B. 0.113 mole of O₂.

Explanation:

We'll begin by calculating the number of mole in 4.05 g of water (H₂O). This can be obtained as follow:

Mass of H₂O = 4.05 g

Molar mass of H₂O = (2×1) + 16 = 2 + 16 = 18 g/mol

Mole of H₂O =?

Mole = mass /Molar mass

Mole of H₂O = 4.05 / 18

Mole of H₂O = 0.225 mole

Next, the balanced equation.

2H₂O —> 2H₂ + O₂

From the balanced equation above,

2 moles of H₂O produced 2 moles of H₂ and 1 mole of O₂.

A. Determination of the number of mole hydrogen produced.

From the balanced equation above,

2 moles of H₂O produced 2 moles of H₂.

Therefore, 0.225 mole of H₂O will also produce 0.225 mole of H₂.

B. Determination of the number of mole oxygen produced.

From the balanced equation above,

2 moles of H₂O produced 1 mole of O₂.

Therefore, 0.225 mole of H₂O will produce = (0.225 × 1)/2 = 0.113 mole of O₂.

Thus, 0.113 mole of O₂ is produced.

all of the following are properties of ionic compounds except:

A. Ionic compounds have low melting points,

B. Ionic compounds have high boiling points

C. Ionic compounds conduct electricity when dissolved in water

D. Ionic compounds are solid at room temperature

Answers

Answer:

Explanation:

They have generally high melting point compared to covalent compounds because they are formed by electrostatic force of attraction between two opposite charge is not easy to melt them in low melting point.

Ionic compounds have high melting and boiling points. Therefore, option A is not a property of ionic compound. Hence, option A is the correct answer.

Ionic compounds are neutral compounds. Ionic compounds are formed from cations and anions. Positively charged ion (cation) and negatively charged ion (anion) are held together with strong ionic bond. Some main properties of ionic compounds are,

High melting point and boiling pointsHave definite size and shapeConduct electricity in molten statesoluble in water and not soluble in organic solvents

Thus, we can conclude ionic compounds have high melting and boiling points. Hence, option A is the correct answer.

How many moles are present in 2.126 g of H2O2 ?

Answers

Answer:

molecular weight of H2O2 or grams. This compound is also known as Hydrogen Peroxide. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles H2O2, or 34.01468 grams.

1 grams H2O2 is equal to 0.029399071224542 mole.

1 grams H2O2 to mol = 0.0294 mol

10 grams H2O2 to mol = 0.29399 mol

20 grams H2O2 to mol = 0.58798 mol

30 grams H2O2 to mol = 0.88197 mol

40 grams H2O2 to mol = 1.17596 mol

50 grams H2O2 to mol = 1.46995 mol

100 grams H2O2 to mol = 2.93991 mol

200 grams H2O2 to mol = 5.87981 mol

There are 0.0625mol in 2.126 g of H2O2.

HOW TO CALCULATE MOLES:

The number of moles of a substance can be calculated by dividing the mass of the substance by its molar mass. That is;

no. of moles (mol) = mass (g) ÷ molar mass (g/mol)

According to this question, 2.126 g of H2O2 were given. The number of moles of H2O2 can be calculated as follows:

Molar mass of H2O2 = 1(2) + 16(2)

= 2 + 32

= 34g/mol

no. of moles = 2.126g ÷ 34g/mol

no. of moles = 0.0625mol

Therefore, there are 0.0625mol in 2.126 g of H2O2..
