We are slowly learning that even if we react, it won't change anything, it won't make people suddenly love and respespect us, it won't magically change their minds. Sometimes it's better to just let things be, let people go, don't fight for closure, don't ask for explanations, don't expect people to understand where you're coming from. We are slowly learning that life is better lived when you don't center it on what's happening around you and center it on what's happening inside you instead.
Work on yourself and you inner peace. ​

Answer:

Natural resource professional

Explanation:

The job title that describes a person with a career in green energy is a hydroelectric technician. The correct option is c.

Green energy is renewable energy and these energies are produced by renewable resources. Renewable resources are the resources that will not be reduced, and these natural resources are present, and these energies can reproduce again by these resources.

The hydroelectric technician is the person who checks the technical problems of a hydroelectric power plant. Hydroelectricity is produced by water.

This is a renewable resource, and it does not produce any kind of pollution, So a hydroelectric technician will be a job title that describes a person with a career in green energy.

Therefore, the correct option is c., hydroelectric technician.

Answer:

3.63 x 10²³molecules

Explanation:

Given parameters:

Mass of methane = 9.65g

Unknown:

Number of molecules  = ?

Solution:

To solve this problem first, we find the number of moles of the given compound or molecule first.

The given molecule is methane;

    CH₄;

     Number of moles  = [tex]\frac{mass}{molar mass}[/tex]

Molar mass of CH₄   = 12 + 4(1)  = 16g/mol

    Number of moles  = [tex]\frac{9.65}{16}[/tex]   = 0.603moles

So;

From mole concept;

      1 mole of a substance contains 6.02 x 10²³ molecules

    0.603moles of methane will contain 0.603  x  6.02 x 10²³

                                                               = 3.63 x 10²³molecules

A

MgCO3→MgO + CO2 balanced

B

NaCl + KI →NaI + KCl balanced

C

Na + O2 →Na2O not balanced the balanced would be 4Na + O2 →2Na2O

D

Ca + MgSO4→CaSO4+ Mg balanced

Answer:

You get some type of pressure that you start to feel in your muscles and joints from gravity and movement. How do they say it? Something called "seat-of-the-pants" (something like that). You get some type of pressure, and your body senses it, and it knows when you are upside-down or not, because if you're not, then you won't get any pressure in your muscle.

Answer:

5.36 × 10²³ molecules

Explanation:

Given data:

Number of moles of silver = 0.89 mol

Number of molecules = ?

Solution:

Avogadro number:

The number 6.022 × 10²³ is called Avogadro number.  

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

Number of molecules of silver:

1 mole contain 6.022 × 10²³ molecules

0.89 mol  ×  6.022 × 10²³ molecules /1 mol

5.36 × 10²³ molecules

Answer:

643.21g  1 mol  6.022^23

262.87 g   1 mol

= 1.4735E24     [Mg3(PO4)2]

Answer:

3.84 kg

Explanation:

CCl4 molar mass: 153.82 g/mol

n = mass / molar mass

25 moles = mass / 153.82 g/mol

mass = 25 x 153.82

mass = 3845 g or 3,84 kg

Answer:

true

Explanation:

It has been an expense for the Australian government (taxpayers) to try to control the rabbit population. This statement is true.

Aside from the lack of natural predators on the continent, their success is aided by rapid reproduction: They can have more than four litters a year, each with up to five kits (baby rabbits).

The European wild rabbit has become an invasive pest in the southern two-thirds of Australia. They have an impact on natural environments, primary production, as well as townships and infrastructure.

The government turned to biocontrol in the 1950s. They released rabbits infected with myxoma, a virus that only affects rabbits, into southeastern Australia.

Thus, It has been an expense for the Australian government (taxpayers) to try to control the rabbit population. This statement is true.

Answer:

ionic

Explanation:

In this instance, fluorine is a non-metal while magnesium is a metal. Ionic bonds are always formed when a metal and a non-metal are combined. Therefore, magnesium fluoride is an ionic compound, and an ionic compound's inter-ion force is always an electrostatic force.

The molecule's ionic bond is exceedingly powerful. When a molecule dissolves in water, it releases a significant amount of ions into the mixture. For the same reason, it conducts electricity as well. This explains why magnesium fluoride is naturally polar.

One type of binary ionic compound is magnesium fluoride. It consists of one magnesium atom and two fluorine atoms. In comparison to fluorine, magnesium is a metal with a substantially lower electronegativity.

Answer:

XZ2

Explanation:

There are different ways in which compounds can be represented. Broadly, we have three different types of formula;

- Structural formular: This shows how th atoms in te compound are connected to each other.

- Molecular formular: This shows the actual number of atoms of element present in the compound

- Empirical Formular: This is the simplest formular of a compound. It basically shows the number of atoms in simple ration to each other.

This question requires us to input the empirical formular;

X2Z4

The ratio of the elements is; 2 : 4 which can be simplified into 1 : 2

Option C (two isotopes of an element)

Explanation:

An isotope is two or more forms of the same element that contain equal numbers of protons (as well as electrons) but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties. For example :-

Isotopes of carbon ⇒

In the question , both the atoms have same number of protons , but their number of neutrons isn't same. Hence , they are the isotopes of an element.

Answer:

electrons fill lower energy levels first before occupying higher energy levels.

Explanation:

The Aufbau's principle describes that electrons fill lower energy levels first before occupying higher energy levels.

In writing the electronic configuration of atoms, the Aufbau's principle is one of the most important principles to consider.

It states that "sublevels with with lower energies are filled up before those with higher energies".

Sublevels do not fill up in numerical order.

Answer:

C) Both have equal numbers of moles.

Explanation:

The number of moles would be the same under the same pressure, volume and temperature.

"If A 5.0 L chamber contains equal pressures of H₂ and N₂ at 25 °C then both gases would have equal number of molecules according to Ideal Gas Law."

Both contain equal number of molecules.

According to Avogadro's Law, 1 mole of every substance occupies 22.4 L at STP.

Thus, equal volume of all gases contain same number of molecules at same temperature and pressure.

[tex]PV=nRT[/tex]

where, P = pressure

V = volume

n = moles

R = gas constant, and

T = Temperature

As volume , pressure and temperature are equal for both [tex]H_2[/tex] and [tex]N_2[/tex] gases, therefore both gases contains equal moles and hence equal number of molecules.
