The total weight of both objects : 7.035 x 10⁻⁸ kg

Given

The weight of a grain of sand : 3.5 x 10⁻¹⁰ kg

The weight of one hair from his eyebrow : 7 x 10⁻⁸ kg

Required

The total weight of both objects

Solution

Scientific Notation consists of 2 parts  

1. the first part: the first digit followed by the decimal point  

2. The second part: the power of 10 (the exponents).which shows the number of digits after the decimal point  

To add/subtract, the exponents must be the same and then add/subtract the coefficient

7 x 10⁻⁸ = 700 x 10⁻¹⁰

[tex]\tt =(3.5+700)\times 10^{-10}\\\\=703.5\times 10^{-10}\\\\=7.035\times 10^{-8}[/tex]

A. the valence electrons

Explanation:

Answer:

The valence electrons

Explanation:

The valence electrons determine an element's properties because chemical properties of each element are determined by the element's electronic configuration and PARTICULARLY by its outermost valence electrons. I hope it helps!

The non-metals are boron and carbon. The metal is aluminum and the metalloid is silicon.

Explanation:

non-metal = boron, carbon

metal = aluminum

metalloid = silicon

Non-metal = boron, carbon

Metal = aluminum

Metalloid = silicon

A solid material which is lustrous, hard, shiny, malleable, and sonorous with good electrical and thermal conductivity.

Metal is an element which is typically hard, shiny, fusible, malleable, and ductile, with good electrical and thermal conductivity.

A nonmetal is an element that does not have the properties of a metal.

A metalloid is an element having intermediate properties of both metals and nonmetals.

Hence,

Non-metal = boron, carbon

Metal = aluminum

Metalloid = silicon

Answer:

5.70×10^-11 m

Explanation:

Replacement  reaction.

Given

A chemical reaction

AB + C → CB + A

Required

reaction type

Solution

There are several types of reactions that can occur

synthesis: 2 elements combine to form a single product

polymerization: monomers combine to produce a polymer

decomposition: One compound breaks down into 2 components

oxidation : a change in oxidation number

replacement can be divided into 2

single replacement if one element replaces the other elements of a compound

double replacement if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds

AB + C → CB + A

If we look at this reaction, element C replaces element A to form a new compound CB. So it is single replacement. But this reaction can also be said to be an oxidation-reduction reaction because there is a change in oxidation number

element A undergoes a reduction reaction

element C undergoes an oxidation reaction

So types of redox reactions can be combination, decomposition, displacement, combustion, and disproportion.

oxidation

Fungi, bacteria, ferns,

Explanation:

bacteria Fungi Ferns are important. decomposers,

I hope it helps you.

There are basically four different categories of decomposers: fungi, insects, earthworms, and bacteria. Fungi, ferns and bacteria are common decomposers.

Decomposers are organisms that disintegrate rotting or dead species; they carry out decomposition, a process only some kingdoms, like fungi, are capable of.

The primary decomposers in nature are fungi, which destroy organic material that would otherwise not be recycled.

Scavengers and decomposers are the two different categories of decomposers. Animals called scavengers hunt down dead plants or animals and consume them. They cut them into small pieces when they eat them.

Each contributes to the food recycling process differently. To transform dead plants or animals into simple substances, fungi release compounds. Some of these elements are absorbed by them for growth, while others go into the soil.

Thus, Fungi, ferns and bacteria are common decomposers.

Meters per second.

Explanation:

Ap3x approved

Answer:

See explanation

Explanation:

Let us recall that a negative ion is formed by addition of electrons to an atom. When electrons are added to the atom, greater interelectronic repulsion increases the size of the Te^2− hence it is greater in size than Te atom. Therefore, the ionic radius of Te^2− is greater than the atomic radius of Te.

In the second question, oxygen is positioned so far to the right because it has a far smaller nuclear charge compared to Te. Hence in the PES spectrum, the 1s sublevel of oxygen lies far to the right of that of Te.

Using principles of atomic structure, the reason why the atomic radius of Te is less than the ionic radius of Te²− is because of the Electrostatic force of repulsion between the negatively charged electrons of Te²- thereby causing the ion to be bigger than the neutral atom.

By considering the second scenario, the element oxygen is positioned so far on the right because it has a very much smaller nuclear charge compared to Te.

As a result, in the PES spectrum, the 1s sublevel of oxygen lies far to the right of the 1s sublevel of Te.

Answer:

True or False

Answer - True

Explanation:

The mantle convection clearly describes how the mantle moves, transferring heat from the white-hot core to the lithosphere. The mantle is usually being heated below and the cooling happens above and the general temperature of the area gets dropped over a long period of time.  

Hot buoyant Magma is being transferred through convection currents, to the lithosphere at the plate boundaries and hot spots. Also, convection current moves cooler materials from the crust to the interior of the earth through a process that is widely known as subduction.

molecular mass = 12×3+1×6 = 36+6 = 42

no. of double bond = 1

Answer:

1.22 g/cm³

Explanation:

Density = mass ÷ volume

Mass = 10.04 grams

Volume = 8.21 cubic centimeters

Density = mass ÷ volume

= 10.04 ÷ 8.21

= 1.2228989037758 g/cm³

Approximately

1.22 g/cm³ to 2 significant figure.

The final answer should be approximated to 2 significant figure because the mass and volume of the objective given is in 2 significant figure
