Answer:
Unsaturated alkene
Explanation:
other answer was wrong
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, the correct option is option D.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
An ionic compound is a metal and nonmetal combined compound. Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.
There are two types of compound in organic chemistry, one is saturated and other is unsaturated. Saturated is the one which possess all single bond and unsaturated is the one which possess either double or triple bond. The given chemical compound is unsaturated alkene.
Therefore, the correct option is option D.

When naming covalent compound both the first and second element in the fomula always receive
a prefix to represent the number of each element present in the chemical formula.
Answer:
Yes.
Explanation:
Yes, both the first and second element in the formula of covalent compound always receive a prefix to represent the number of each element present in the formula in order to show the percentage or proportion of each element in the formula of covalent compound. Prefix refers to addition of word, letter, or number at the beginning of something so here number placed in front of element indicates the prefix.

A mirror forms an image because of which behavior of light?
refraction
reflection
diffraction
absorption
Answer: reflection
Explanation:
A mirror forms an image because of reflection of light. Therefore, the correct option is option B among all the given options.
What is light?Light is the electromagnetic radiation that is visible with the eye. Electromagnetic radiation has a very broad wavelength range, ranging from gamma rays having wavelengths shorter than around 1 1011 metre to radio waves with wavelengths measured in metres.
The spectral areas next to the visible band, infrared at one end as well as ultraviolet at the other, are often commonly referred to as light. The velocity of light in the vacuum is indeed a basic physical constant, with the current accepted value being 299,792,458 meters per second, or approximately 186,282 miles a second. A mirror forms an image because of reflection of light.

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
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.

Answer:
D) none of these
Explanation:
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
Answer:
A
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 solventsThus, we can conclude ionic compounds have high melting and boiling points. Hence, option A is the correct answer.

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
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.
How many moles are present in 2.126 g of H2O2 ?
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/molno. of moles = 0.0625molTherefore, there are 0.0625mol in 2.126 g of H2O2..Learn more at: https://brainly.com/question/21085277?referrer=searchResults

no
potassium bromide lead(II) nitrate
yes
no
ammonium bromide sodium hydroxide
yes
no
Answer:
1) No, 2) Yes, 3) Yes
Explanation:
Refer to solubility rules to understand if a precipitate occurs between a mix of solutions.
Two solutions form a precipitate if they react to yield an insoluble product.
Let us now consider each of the reacting species one after the other.
In the first case;
Zn(NO3)2(aq) + FeI2(aq) ----> ZnI2(aq) + Fe(NO3)2(aq)
The two products of the reaction are soluble so no precipitate is formed.
In the second case;
2KBr(aq) + Pb(NO3)2(aq) ------> 2KNO3(aq) + PbBr2(s)
An insoluble product PbBr2 is formed hence a precipitate is formed.
In the third case;
NH4Br(aq) + NaOH(aq) -------> NH4OH(aq) + NaBr(aq)
No insoluble product is formed so the there is no precipitate.
