For the balanced equation shown below, how many moles of H2O will react with 9 moles of N2?
N2 + 4H2O --> 2H2O2 + N2H4
Answer:
36 mole of H20
Explanation:
N2 + 4H2O --> 2H2O2 + N2H4
H20 : N2
4 : 1
x : 9
cross multiplication
so,
= 9x4/1 = 36 mole of H20
I hope this helps a little bit.

1 In what type orbital are the outer electrons of the atoms of the elements of Group 1 (IA) and Group 2 (IIA)?
Answer:
s orbital
Explanation:
The elements of Group 1 (IA) and Group 2 (IIA) have one and two electrons in their outermost shells respectively.
For the elements in group Group 1 (IA), the general outer electron configuration is ns1. This last electron is accommodated within an s orbital.
For the elements in Group 2 (IIA), the two outermost electrons are accommodated in an ns orbital, hence the answer.

Dehydration synthesis reactions build molecules up and generally require energy, while hydrolysis reactions break molecules down and generally release energy. Carbohydrates, proteins, and nucleic acids are built up and broken down via these types of reactions, although the monomers involved are different in each case

Explanation:
in the rainforest, plants that live on the forest floor have different adoptions from plants that live high up in the canopy. what is the main reason that leaves of plants on the rain forest floor are much wider than those found higher in the canopy of the rain forest?
1: these plants produce poisons that plants in other area do not.
2: these plants have less access to light then plants in other areas.
3: These plants need to take in more water than plants in other areas.
4: these plants have more natural predators then plants in other areas.
Answer:
option 3, the leaves higher up need less water since there getting more light and the ones lower need to adapt to gaining more water since they won't be seeing much light

What does it mean to be limiting or excess? (Limiting Reactant)
Answer:
Find the limiting reagent by calculating and comparing the amount of product each reactant will produce. Balance the chemical equation for the chemical reaction. The reactant that produces a lesser amount of product is the limiting reagent. The reactant that produces a larger amount of product is the excess reagent.

Explain the meaning of thermal energy transfer and give specific examples of conduction, convection, and radiation.
Answer:
thermal energy: the part of total internal energy that can be transferred (a portion of the kinetic energy)
heat is the thermal energy that flows from one substance to another due to a temperature difference.
Thermal energy is measured in temperature change.
Thermal energy transfer stops when thermal equilibrium is achieved (Both substances at the same temperature).
conduction: Transfer of thermal energy through a solid object like heat transferring up a metal spoon from a hot cup of coffee.
convection: the transfer of thermal energy due to the movement of a liquid or gas caused by differences in temperature. Only in a fluid (liquid or gas). Breezes, ocean currents.
radiation: Transfer energy with or without matter. Warming from the Sun, microwave oven.
Answer:
Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas. Radiation is the transfer of thermal energy through thermal emission. Hope this helps!

What is a fault, and how does the existence of faults support the theory of plate tectonics?
“Many of the objections are long standing but apparently unknown to many geophysicists, while some are peculiar to the new global tectonics. The conclusions drawn, in order of probability, are (1) the continents have almost certainly not moved with respect to each other; (2) convection is not active throughout the whole mantle; (3) even if convection is active in the upper mantle it cannot account for drift; (4) pole positions derived from paleomagnetism, and results of this method of investigation in its global form generally, are afflicted with an unknown cause of error and are in any case too inexact for drift reconstructions.”

Whats the formula for Nickel (IV) chloride?
The molecular formula for Nickel (IV) Chloride will be NiCl₂. Nickel reacts with chloride to form a salt. The salt is yellow in color and anhydrous.
What is molecular formula?A molecular formula is a way of presentation of chemical formula of a compound. It gives the information related to the type of atoms, number of atoms which constitutes the compound and the chemical properties.
Molecular formula of a chemical compound can be derived by the valency of element. In this question, molecular formula of the compound can be derived by:
Valency of Nickel = 2
Valency of Chlorine = 1
By the cross-multiplication of valency:
element 1(valency of element 2). element 2 (valency of element 1)
= Ni (1). Cl(2)
= NiCl₂
Therefore, the molecular formula of Nickel (IV) chloride will be NiCl₂.

The noble gas configuration of vanadium (V), atomic number 23 will be [Ar] 3d34s2.
What is noble gas configuration ?The electron configuration of noble gases would be known as that of the noble gas configuration. The propensity of chemical elements to gain stability forms the foundation of all chemical reactions. Chemical formation frequently leads to an entire electronic configuration approximating a noble gas for several main group elements.
