Answer:
carboxyl group (COOH) and amines
Explanation:
The two functional group present in the shown molecule are carboxylic acid group and amine group.
What are functional groups?Functional group is defined as a substituent or group of toms or an atom which causes chemical reactions.Each functional group will react similarly regardless to the parent carbon chain to which it is attached.This helps in prediction of chemical reactions.
The reactivity of functional group can be enhanced by making modifications in the functional group .Atoms present in functional groups are linked to each other by means of covalent bonds.They are named along with organic compounds according to IUPAC nomenclature.
Functional group inter conversion is also possible by retro -synthesis.In some cases , functional groups can be charged molecules.

The theoretical yield of NH3 is 945 grams. You conducted the experiment and only produced 598 grams.
Answers
Answer:
Given theoretical yield of NH3 is 945g.
The actual yield is 598g.
What is the %yield?
Explanation:
%yield of a chemical reaction can be calculated by using the formula:
[tex]%yield=\frac{actual yield}{theoretical yield} * 100[/tex][tex]\frac{actual yield}{theoretical yield} * 100[/tex]
Substitute the given values in this formula to get the %yield.
[tex]\frac{598g}{945g} * 100\\=63.3[/tex]
Hence, the %yield for the formation of ammonia is ---- 63.3.

Which of the following substances are ionic?
Check all that apply.
AlCl3
MgI2
C2H5OH
NH3
Explanation:
An ionic substance is formed between a positively charged cation and a negatively charged anion.
Ionic substances are generally formed from metal and nonmetal atoms with the metal atoms forming the cations and the nonmetal atoms forming the anions.
Among the given substances,
MgI2 is an ionic substance.
Since Mg is the metal atom. It forms a cation.
I is a nonmetal atom. It forms anion.
Hence,
MgI2 is an ionic substance.
Though AlCl3 looks like an ionic substance it is a covalent compound.
This is due to the high polarizability of [tex]Al^3+[/tex] ion.
The remaining two compounds do not contain any metal atoms.
So, ethanol and NH3 are not ionic compounds.

Fe2O3 (s) + CO (g) -> Fe(s) + CO2 (g) (unbalanced)
1.Calculate the number of grams of CO that can react with 0.150kg of Fe2O3
2. Calculate the number of grams of Fe and the number of grams of CO2 formed
when 0.150 kg of Fe2O3 reacts
Answers
Answer:
1. 78.9g of CO
2. 104.9g Fe and 124.0g CO2
Explanation:
Based on the balanced reaction:
Fe2O3 (s) + 3CO (g) -> 2Fe(s) + 3CO2 (g)
1 mole of Fe2O3 reacts with 3 moles of CO to produce 2 moles of Fe and 3 of CO2
1. The moles of 0.150kg = 150g of Fe2O3 -Molar mass: are:
150g * (1mol / 159.69g) = 0.9393 moles Fe2O3
Moles CO:
0.9393 moles Fe2O3 * (3mol CO / 1mol Fe2O3) = 2.818 moles CO
Mass CO -Molar mass: 28.01g/mol-:
2.818 moles CO * (28.01g/mol) = 78.9g of CO
2. The moles of Fe produced are:
0.9393 moles Fe2O3 * (2mol Fe / 1mol Fe2O3) = 1.8786 moles Fe
Mass Fe -Molar mass: 55.845g/mol-:
1.8786 moles Fe * (55.845g/mol) = 104.9g Fe
The moles of CO2 produced are:
0.9393 moles Fe2O3 * (3mol CO2 / 1mol Fe2O3) = 2.818moles CO2
Mass CO2 -Molar mass: 44.01g/mol-:
2.818moles CO2 * (44.01g/mol) = 124.0g CO2

Explanation:
The gas planets are Jupiter, Saturn, Uranus and Neptune.
Answer:
A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. These four large planets, also called jovian planets after Jupiter, reside in the outer part of the solar system past the orbits of Mars and the asteroid belt. Jupiter and Saturn are substantially larger than Uranus and Neptune, and each pair of planets has a somewhat different composition.Although there are only four large planets in our solar system, astronomers have discovered thousands outside of it, particularly using NASA's Kepler Space Telescope. These exoplanets (as they are called) are being examined to learnmore about how our solar system came to be.Explanation:

Answers
Answer:
may or may not be equal to the number of moles of the products.
Explanation:
A chemical reaction involves the interaction between reactants to yield products. The number of moles of reactants and products in the system depends on the stoichiometry of the reaction.
The balanced reaction equation shows us the number of moles of reactants and products involved in the reaction.
Hence, in the balanced chemical reaction equation; the number of moles of reactants may or may not be equal to the number of moles of the products.

How many grams of ammonia (NH3) can be produced by the synthesis of excess hydrogen gas (H2) and 253.8 grams of nitrogen gas (N2) in a synthesis reaction?
Answers
Answer:
308.2 g of NH₃.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
3H₂ + N₂ —> 2NH₃
Next, we shall determine the mass of N₂ that reacted and the mass of NH₃ produced from the balanced equation. This can be obtained as follow:
Molar mass of N₂ = 2 × 14 = 28 g/mol
Mass of N₂ from the balanced equation = 1 × 28 = 28 g
Molar mass of NH₃ = 14 + (3×1)
= 14 + 3 = 17 g/mol
Mass of NH₃ from the balanced equation = 2 × 17 = 34 g
Summary:
From the balanced equation above,
28 g of N₂ reacted to produce 34 g of NH₃.
Finally, we shall determine the mass of NH₃ produced by the reaction of 253.8 g of N₂. This can be obtained as illustrated below:
From the balanced equation above,
28 g of N₂ reacted to produce 34 g of NH₃.
Therefore, 253.8 g of N₂ will react to produce = (253.8 × 34)/28 = 308.2 g of NH₃.
Thus, 308.2 g of NH₃ were obtained from the reaction.
