Answer: NO
Explanation:
As per the given balanced equation, 2 moles of NO reacts with 2 moles of CO. Hence, 3 g or 1.07 moles of CO needs to react with the same number of moles of NO. But we have only 3 g or 0.1 mole of NO. Hence, NO is the limiting reactant.
What is limiting reactant ?A limiting reactant in a reaction is the reactant which is fewer in amount or consume early without complete reaction with other reactants. Hence, as soon as this reactant is consume, the reaction stops.
Given 2 moles of NO reacts with 2 moles of CO.
molar mass of NO = 30 g/mol
molar mass of CO = 28 g/mol.
Number of moles in 3 g of CO = 3/28 = 1.07 moles
number of moles in 3 g of NO = 3/30 = 0.1 moles.
1.07 moles of CO needs 1.07 moles of NO. But only 0.1 moles are present.
Therefore, NO is the limiting reactant in this reaction.

How many moles of MgO are produced if 0.37 moles of O2 react with excess of Mg?
Answer:
yez so the answer is mg 1.0
Explanation:
The excess reactant is present in an amount that is greater than required. The amount of MgO that is produced in the reaction is 0.74 moles.
What is an excess reactant?An excess reactant is that reantant thatis present in an amount that is more than required.
Now we are told that the magnessium is the reactant in excess so we have to use the amount of oxygen.
The reaction is: 2Mg + O2 ---->2MgO
1 mole of O2 produces 2 mole of MgO
0.37 moles of O2 produces 0.37 moles * 2 moles/1 mole
= 0.74 moles

How many lone pairs does this molecule have?
Answer:
Just 1 i.e., Option B.
Because except for top of the molecule, all other sides are filled with a letter meaning there is one free space.
Answer:
B
Explanation:
H . + H . -----> H:H {":" represents a covalent bond, that is, a shared pair of electrons}
A Lewis structure is a convention used to represent the covalent bonding in a molecule. Dots or lines are used to represent
valence electrons (electrons available for bonding). The Lewis structure for the hydrogen molecule is as follows.
H:H or H-H
A bonding pair is an electron pair shared between two atoms.
A nonbonding pair (lone pair, unshared pair) is a pair of electrons that remains on one atom and is not shared.
classify matter as elements mixtures and compounds
Answer:
An element contains just one type of atom. A compound contains two or more different atoms joined together. A mixture contains two or more different substances that are only physically joined together, not chemically. A mixture can contain both elements and compounds.
Which of the following statement is wrong?
A)Leaves can make food when there is sunlight
B)Stamen will develop into a fruit
C)Stem helps in the conduction of water
D)Plants need air, water and sunlight to grow
Answer:
C) Stem helps in the conduction of water
Explanation:
It's the xylem and phloem present in the vascular bundles of stems that conduct water and minerals across the plant. Stems bear flowers and fruits in a position that facilitates the processes of pollination, fertilization, and dispersion of seeds. So, stem doesn't help in the conduction of water.

Answer:
1037.56 mph
Explanation:
We are told the distance around the earth which is the circumference is 40075 km.
Converting to miles gives 24901.451 miles
Formula for speed = distance/time
Time for one rotation is 24 hours.
Thus, speed = 24901.451/24 = 1037.56 mph

Which pair represents an acid and its conjugate base?
Answer:b
Explanation:
bc
In the given chemical equation, H₃PO₄ is an acid while it's conjugate base is OH⁻.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

What is the mass in grams of 0.94 moles of sodium bicarbonate. NaHCO3?
Mass of a substance = Moles of a substance × molar mass of a substance
We have 0.94 moles of NaHCO3. The molar mass of NaHCO3 is the sum of the atomic masses of the elements comprising NaHCO3, which is approximately 84.007 g/mol.
The mass of 0.94 moles of sodium bicarbonate is therefore (0.94 moles NaHCO3)(84.007 g NaHCO3/mol NaHCO3) = 78.97 ≈ 79 grams of sodium bicarbonate.

.When sodium atoms (Na) and chlorine atoms (Cl) join to make sodium chloride, or table salt, they form an ionic bond. Using this information, which pair of elements is most likely to form an ionic bond?
potassium (K) and fluorine (F)
aluminum (Al) and aluminum (Al)
sulfur (S) and oxygen (O)
calcium (Ca) and neon (Ne)
Answer:
potassium (K) and fluorine (F)
Explanation:
Potassium is an alkali metal just like sodium and fluorine is a halogen just like chlorine. A metal and nonmetal will often join to form an ionic compound.
Aluminum, if it was going to bond to itself, would be a metallic bond.
Sulfur and oxygen are both nonmetals and would form a covalent bond.
Calcium would not bond with neon as neon is a noble gas.
Answer:
A) potassium (K) and fluorine (F)

What is the formula for the compound formed by Al3+ and N3- ?
Answer:
[tex]\boxed {\boxed {\sf AlN}}[/tex]
Explanation:
The goal when forming compounds is to achieve a net charge of 0.
We are given aluminum with a charge of 3+ and nitrogen with a charge of 3-.
These charges are equal and opposite, so one of each will equal 0.
3+ (Al) + 3- (N) = 0Therefore, we do not need any subscripts. List the metal's symbol (aluminum) then the nonmetal.
AlNTh formula for the compound, which is aluminum nitride, is AlN.

Answer:
Will likely be the same
Explanation:
We can see in both pictures there is a black molecule and a red molecule. However, we also have a purple molecule in one image and a yellow in the other. It would LIKELY be the same because we have more of the same molecules then more different molecules. Hope this helps
