How many unpaired electrons are present in the ground state of the atoms in Group 4A(14)?
unpaired electrons
Answer:
the correct answer is 2
Explanation:
i just did this assignment :)
There will be 2 unpaired electrons in p orbital of unpaired electrons present in the ground state of the atoms in Group 4A(14).
What are unpaired electrons?The unpaired electrons are those which do not have any pair due to absence of no more electrons and they are highly unstable elements if the electrons are not paired in the orbitals.
There are 4 types of orbitals s, p, d, and f s-orbital consist of one pair of electrons to fill and the p-orbital have 3 blocks which can be filled with 3 pair that is 6 electrons after filling, and two unpaired electrons left in p-orbital.
Therefore, in the ground state of the atoms in Group 4A(14) 2 unpaired electrons in the p orbital of unpaired electrons are present.

10. Haley the hummingbird can fly from a pansy flower to a hibiscus flower 20 meters away in 5 seconds.
What is her speed?
Answer:
4
Explanation:
Speed=Distance/time, so 20/5 divide time divided by distance. so the answer is 4.
The speed of Haley the hummingbird is 4 m/s.
From the question,
We are to calculate the speed of Haley the hummingbird
Speed is given by the formula
[tex]Speed =\frac{Distance\ traveled}{Time\ taken}[/tex]
From the given information,
The hummingbird can fly from a pansy flower to a hibiscus flower 20 meters away in 5 seconds.
That is,
The bird can cover a distance of 20 meters in 5 seconds.
Therefore,
Speed of the hummingbird = [tex]\frac{20}{5}[/tex]
Speed of the hummingbird = 4 m/s
Hence, the speed of Haley the hummingbird is 4 m/s.

Which statement BEST explains whether or not matter is conserved in this chemical reaction? A Matter is being conserved because there is an equal number of atoms of each element in the reactants and products, and the total mass of the reactants is equal to the total mass of the products. B Matter is not being conserved because there are more atoms of oxygen in the reactants than there are in the products, so there is also more mass in the reactants than there is in the products. C Matter is being conserved because carbon, hydrogen, and oxygen are found in the reactants and in the products in different arrangements, and the mass of the reactants is equal to the mass of the products. D Matter is not being conserved because there are 11 units in the reactants, one C8H8 and 10 O2, and 12 units in the products, eight CO2 and four H2O, so there is also more mass in the products that in the reactants.
Answer:
D
Explanation:
The matter is being conserved because the equal number of atoms of each element in the reactants and products, and the total mass of the reactants is equal to the total mass of the products. Therefore, option (A) is correct.
What is the law of conservation of matter?One or more initial substances change into different substances in any chemical change. Both the initial and final substances are made up of atoms as all matter is made up of atoms.
According to the law of conservation of matter, matter can neither be created nor destroyed, we just can convert it from one form to another. So the same number and kind of atoms before and after the chemical change are present.
According to this law, the total mass of the reactants in a chemical reaction must be equal to the total mass of products for a low-energy thermodynamic process.

How many grams of Phosphorus is required to complete combustion of 40g Oxygen P+O2-mm>P2O5 . Please balance
Answer:
Mass = 31 g
Explanation:
Given data:
Mass of phosphorus required = ?
Mass of oxygen = 40 g
Solution:
Chemical equation:
4P + 5O₂ → 2P₂O₅
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 40 g/ 32 g/mol
Number of moles = 1.25 mol
Now we will compare the moles of P and oxygen.
O₂ : P
5 : 4
1.25 : 4/5×1.25 = 1
Mass of phosphorus:
Mass = number of moles × molar mass
Mass = 1 mol × 31 g/mol
Mass = 31 g

B. Sections 2 and 3
C. Sections 1 and 4
D. Sections 2, 3, and 5
In sections 1 and 4 the ball is subjected to a balanced force. Hence, option C is correct.
What is the frictionless surface?A Frictionless surface refers to that kind of surface where the force acting on any object which makes it difficult for the object to slide is almost zero or negligible, i.e., no resistance between surface or substance allowing the object to slide and move freely without any friction.
In sections 1 and 4 the ball is subjected to a balanced force. Hence, option C is correct.
