Draw the Lewis structure for the tellurium tetrabromide (TeBr_4)molecule.
Answers
Tellurium tetrabromide molecule have one tellurium atom and four Bromine atoms. The bonds are formed by electron sharing and so the bond between them are covalent bonds.
Tellurium tetrabromide is an inorganic compound. Tellurium have 6 valence electrons in its outer shell. Four of these valence electrons bonds to four bromine atoms, which has 7 valence electrons. A single bond is formed between each bromine and tellurium. Tellurium has a remaining lone pair of electrons.
Lewis structure of molecules means the simplest way of depicting all the atoms in a molecule, valence electrons of all molecules and the bonds that are formed. The binds are denoted by lines and electrons by dots.
Tellurium tetrabromide have one tellurium atom covalently bonded to four bromine atoms.

Do you think personality
traits are primarily inherited
from your parents or
influenced by the
environment? What is your
evidence you researched?
Answers
Personality traits are influenced by a combination of genetic and environmental factors. Research suggests that both genetics and the environment play significant roles in shaping an individual's personality.
Studies on twins and adoption give proof that genetics affect personality. When opposed to fraternal twins, who only share 50% of their genetic makeup, identical twins, who share 100% of their genetic material, frequently show stronger similarities in personality traits. This shows that certain personality traits are influenced by hereditary factors.
Yet, environmental influences also have a considerable impact on personality. Despite having comparable DNA, studies on non-twin siblings reared in the same home have found that they frequently display personality differences.
This shows that the environment, including parental practices, cultural influences, and life events, has a significant impact on personality development.

2 H2 + O2 → 2 H2O
We interpret this as “two molecules of hydrogen react with one molecule of oxygen to make two molecules of water.” The chemical equation is balanced as long as the coefficients are in the ratio 2:1:2. For instance, this chemical equation is also balanced:
100 H2 + 50 O2 → 100 H2O
This equation is not conventional—because convention says that we use the lowest ratio of coefficients—but it is balanced. So is this chemical equation:
5,000 H2 + 2,500 O2 → 5,000 H2O
Again, this is not conventional, but it is still balanced. Suppose we use a much larger number:
12.044 × 1023 H2 + 6.022 × 1023 O2 → 12.044 × 1023 H2O
These coefficients are also in the ratio of 2:1:2. But these numbers are related to the number of things in a mole: the first and last numbers are two times Avogadro’s number, while the second number is Avogadro’s number. That means that the first and last numbers represent 2 mol, while the middle number is just 1 mol. Well, why not just use the number of moles in balancing the chemical equation?

Determina la densidad de una barra dd hierro cuya masa ed de 160gr y su volumen es de 20,35cm³ ¿que volumen ocuparan 12g de hierro?
Answers
Answer:
15.26 cm³
Explanation:
La densidad de una sustancia se define como su masa por unidad de volumen:
densidad = masa/volumen
Tenemos los siguientes datos de la barra de hierro:
masa = 160 g
volumen = 20,35 cm³
Por lo tanto, la densidad de la barra de hierro es:
densidad = 160 g/20,35 cm³ = 0.786 g/cm³
El volumen de 12 gramos de hierro se calcula utilizando el dato de masa (12 g) y la densidad calculada:
densidad = masa/volumen ⇒ volumen = masa/densidad
= 12 g/(0.786 g/cm³)
= 15.26 cm³

Answers
Answer:
D
Explanation:
because the rest don’t make any sense
A light-year unit is very large and distances in space are very large. Therefore, the correct option is option D.
What is distance?No matter the direction of the journey, distance is the overall path that an item in motion has traveled. Since just the length of the path travelled is calculated as well as the motion's direction is ignored, distance is referred to as a scalar number. The distance can only ever be positive; it can never be 0 or negative.
Displacement generally defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into consideration both the directions of the motion and the amount of the changing position. Displacement may be zero, positive, or negative. A light-year unit is very large and distances in space are very large.
Therefore, the correct option is option D.

Answers
Answer:
First Statement is correct
Explanation:
An electron is transferred from sodium to chlorine and ionic bond is formed.
Hope it help!!
If sodium ( Na ) bonds with chlorine ( Cl ), then an electron is transferred from sodium to chlorine and an ionic bond is formed. Therefore, option A is correct.
What is ionic bond ?The main interaction taking place in ionic compounds is ionic bonding, a form of chemical bonding that includes the electrostatic attraction between two atoms or ions with dramatically differing electronegativities.
When the ionic character is larger than the covalent character, i.e., when there is a significant difference in the electronegativity between the two atoms, the bond is more polar than when the electrons are divided more evenly in covalent bonding.
The ionic bond found in the salt sodium chloride is an illustration of this type of connection. The valence electron from sodium is transported to chloride's outer electron shell.
Thus, option A is correct.

How much heat is absorbed in the complete reaction of 3.00 grams of SiO2 with excess carbon in the reaction SiO2(g) + 3C(s) → SiC(s) + 2CO(g) ΔH° = 624.7 kJ/mol?
Answers
Answer:
31.24 kJ
Explanation:
SiO₂(g) + 3C(s) → SiC(s) + 2CO(g) ΔH° = 624.7 kJ/molFirst we convert 3.00 grams of SiO₂ to moles, using its molar mass:
3.00 g SiO₂ ÷ 60.08 g/mol = 0.05 molNow we calculate the heat absorbed, using the given ΔH°:
If the complete reaction of 1 mol of SiO₂ absorbs 624.7 kJ, then with 0.05 mol:
0.05 mol * 624.7 kJ/mol = 31.24 kJ of heat would be absorbed.The heat absorbed by 3.00 grams of SiO2 is 31.17 kJ/mol.
The thermochemical equation is;
SiO2(g) + 3C(s) → SiC(s) + 2CO(g) ΔH° = 624.7 kJ/mol
The number of moles of SiO2 = 3.00 g/60.08 g/mol = 0.0499 moles
From the reaction equation;
1 mole of SiO2 absorbs 624.7 kJ/mol
0.0499 moles SiO2 absorbs 0.0499 moles × 624.7 kJ/mol/1 mole
= 31.17 kJ/mol

p = 36400 kg·m/s
Explanation:
p=mv
p= Momentum
m= mass (1300 kg)
v= 28

= 36400 kg·m/s
The Momentum of the car is 36400 kg-m/s.
What is Momentum ?Momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. m is an object's mass and v is its velocity
Given that,
Mass of the car, m = 1300 kgSpeed of the car, v = 28 m/s (towards north)(m is an object's mass and v is its velocity)
To find :
The momentum of car, p
Solve :
Let p is the momentum of an object. It can be calculated by the product of mass and its velocity. The formula to find it is given by :
p = m x v
