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.

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 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.
The atomic number of V = 23

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.
Explanation:
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.

a. Ca(OH) 2 _______________________________=
b. H 2 O 2 _______________________________=
c. KCl _______________________________=
d. NaH 2 PO_______________________________=
Answer:
a. Ca(OH)₂ = 74.08 g/mol
b. H₂O₂ = 34 g/mol
c. KCl = 74.55 g/mol
d. NaH₂PO₄ = 119.97 g/mol
Explanation:
In order to determine the molar mass of each compound we need to sum, the molar mass of each element.
a. Ca(OH)₂
40.08 g/mol (Ca) + 2 . 16 g/mol (O) + 2 . 1 g/mol (H) = 74.08 g/mol
b. H₂O₂ → 2 . 1 g/mol (H) + 2 . 16 g/mol (O) = 34 g/mol
c. KCl → 39.1 g/mol (K) + 35.45 g/mol (Cl) = 74.55 g/mol
d. NaH₂PO₄
23 g/mol (Na) + 2 . 1 g/mol (H) + 30.97 g/mol (P) + 4 . 16 g/mol (O) = 119.97 g/mol

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

P4O6
balance the equation
To balance a chemical equation, both sides should have equal mass, or in other words both sides should have same number of atoms as to follow the conservation of mass rule.
P + O₂ = P₄O₆
LHS:
Number of Phosphorus atoms = 1 atom
Number of Oxygen atoms = 2 atoms
RHS:
Number of Phosphorous atoms = 4 atoms
Number of Oxygen atoms = 6 atoms
Also since P₄O₆ has the most number of atoms we will make the LHS equalize to P₄O₆.
Difference between Phosphorous atoms in LHS to RHS = 3
Since phosphorous is a monatomic we need 3 phosphorous atoms extra
Difference between Oxygen atoms is LHS to RHS = 4
But Oxygen is diatomic, so we need 4/2 = 2 Oxygen molecules
Now lets see if it is balanced
P + 3P + O₂ + 2O₂ -------> P₄O₆
4P + 3O₂ ------> P₄O₆
LHS:
Phosphorous atoms = 4 atoms
Oxygen atoms = 3 × 2 = 6 atoms
RHS:
Phosphorous atoms = 4 atoms
Oxygen atoms = 6 atoms
LHS = RHS
Therefore the balanced equation is 4P + 3O₂ = P₄O₆
