Explanation:

The units that acceleration use are distance/time^2  (in metric units).

The acceleration is the change of velocity over time, so

In another way, if the velocity is constant, the acceleration is zero, but if the velocity change over the time (as a car do when the red light change), the acceleration takes value!.

Answer:

ridge push and slab pull

Explanation:

there are two processes through to be responsible for the spreading seen at mid ocean ridges and there is some uncertainty as to which is dominant. ridge push occurs when the weight of the ridge pushes at the rest of tectonic plate away from the ridge often towards a subduction zone. hope this helped

The mole fraction of sulfuric acid : 0.073

Given

3.75 M sulfuric acid solution that has density of 1.230 g/mL

Required

The mole fraction

Solution

3.75 M = 3.75 mol/L

For 1 L solution :

mass of solution = 1230 g

mass Sulfuric acid : 3.75 mol x 98 g/mol=367.5 g

mass water = 1230-367.5 = 862.5 g

mol water = 862.5 : 18 g/mol= 47.92

mol total = 3.75 + 47.92 = 51.67

mole fraction of sulfuric acid :

= 3.75 : 51.67

= 0.073

Answer:

C

Explanation:

The oxygen family consists of the elements that make up group 16 on the periodic table: oxygen, sulfur, selenium, tellurium, and polonium. These elements all have six electrons in their outermost energy level, accounting for some common chemical properties among them.

Answer:

they all have 6 valence electrons

Explanation:

all elements in group 16 have 6 valence electrons

Answer: No.

Explanation: Unless a disaster happens to their environment their scales will only grow.

The maximum temperature : a. 745 K

Given

Gas at 25°C(298 K) and at a pressure of 0.800 atm

Final pressure = 2 atm

Required

Final temperature

Solution

Gay Lussac's Law  

When the volume is not changed, the gas pressure in the vessel is proportional to its absolute temperature  

[tex]\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]

Input the value :

T₂=(P₂T₁)/P₁

T₂=(2 atm x 298 K)/0.8 atm

T₂ = 745 K = 472 °C

We use roman numerals to indicate the oxidation state of metal atoms when naming compounds especially in the case of coordination compounds. It is a standard system of nomenclature.

Oxidation state of a species is the number electrons gained or lost. Oxidation state increases if electrons are lost from the atom and it will be decreased if electrons are gained.

For example, copper is in + 2 oxidation state in CuSO₄, thus it can be indicated as Cu(II). Copper can exists is +3 oxidation too. Thus the representation will be Cu (III).

All the transition metals like copper exhibit various oxidation state. So it is important to indicate in which oxidation state they are in a particular compound. In the compound Fe₂O₃, iron is in + oxidation state whereas in FeSO₄, it can be +2 . Thus it is important to note whether it is Fe (II) or Fe (III).

Answer:

A) gain an electron and increase in size

Explanation:

Fluorine is a Group 17 element, making it a halogen. This means that it has 7 valence electrons in its outer shell. It only needs one more electron to fill its outer shell and gain stability. When fluorine becomes an ion, it gains an electron and becomes F⁻. Adding electrons creates a larger ion because the electrons occupy a larger volume due to mutual repulsions pushing them apart.

Hope that helps.

When a fluorine atom becomes an anion, it will gain an electron and increase in size. Therefore, option (A) is correct.

An ion is a chemical specie that holds a positive or negative charge. The term ‘ion’ refers to atoms or molecules with non-zero net charges associated with them. Therefore, all ions have either a greater number of electrons than protons in their atomic structures or a greater number of protons than electrons.

If the number of protons is greater than electrons are termed to hold a net positive charge and are commonly referred to as cations. The ions that contain a greater number of electrons than protons hold a net negative charge and are known as anions.

The electronic configuration of the fluorine is 1s²2s²2p⁵. As the fluorine atom accepts one electron in its valence shell it becomes anion F⁻. The number of protons is less than electrons therefore effective nuclear charge decreases and the size of the ion increases.

Answer:

In the gold crystal, the atoms are bonded by freely moving electrons. In the salt crystal, the atoms are bonded by the attraction of opposite electrical charges.

Explanation:

A.pex

A crystal of Gold (Au) has metallic bonding whereas a crystal of NaCl has ionic bonding.

Chemical bonding refers to the formation of a chemical bond between two or more atoms, molecules or ions to give rise to a chemical compound.

Ionic bonding occurs by transfer of electrons from one atom to another and is usually between a metal and a non metal atom. This type of bond is classically described as occurring when atoms interact with one another to either lose or gain electrons.

Metallic bonds are the chemical bonds that hold atoms together in metals.

Therefore, A crystal of Gold (Au) has metallic bonding whereas a crystal of NaCl has ionic bonding.
