what is the total charge? plz help!

Answer:

dressing is for salad and tea is a drink but the are both liquids and brown

I'm assuming you're talking about atomic radius. It'd be the 2nd.

Fluoride has the smallest (group 17)

Oxygen has the 2nd smallest (group 16)

Sodium has the largest (group 1)

Sorry it took so long, didn't know it was multiple choice :)

Chemical formula

Explanation:

because chemical formulas use chemical elements , symbols , and numbers to present information about the chemical proportions.

Answer:

1 cc=1 ml=0.001 liter

Explanation:

One cubic centimeter has the same volume as one milliliters. Both are equally used in analytical problems to express the volume of a substance.

Volume is a physical quantity that measures the total space occupied by a substance. Volume is an extensive quantity and thus depends on the amount of the substance.

The mass of a substance per unit volume is called its density. Volume is dependent on the intermolecular forces between the particles of the substance. The SI unit of volume is liter (L). Other units are ml, cm³, dm³ etc.

One cubic centimeter has the volume as one milliliters.

Hence, 1 cm³ = 1 ml

1000 m or 1000 cm³ is one liter of the substance.

Edge 2020

The impact of glaciers on the surface is that glaciers scraped across the surface and altered landscapes and the course of rivers.

A glacier refers to a heap of ice that has stayed there for a large number of years. The earth is filled with many glaciers and about 90% of fresh water are trapped in glaciers.

Answer:

The Earth rotates on its axis at a constant tilt.

Earths rotation on its axis at a constant tilt provides seasonal changes in the different part of the country. This resulted to the distribution of the heat of the sun from northern hemisphere and to southern hemisphere. Making areas with hot temperature may experience rainy season in a year. This will help production of crops or food supply and water supply available for living organism.

If the Earth's rotation is not tilted, then both the northern hemisphere and southern hemisphere will be covered with thick ice sheet. The equatorial region or near the equatorial region will experience tremendous warm temperature. Making our life on Earth not ideal for living.

Magnetic Field

Earth is protected by the magnetic from the dangerous radiation coming from the heat of the sun.

Water and oxygen

These two elements are essential for living organism in order to survive. The existence of waters proves that Earth temperature is conducive for living.

Explanation:

Answer : The cost of pennies to buy 125 L of gasoline would be, $71.92

Explanation :

As we are given that the cost to buy gasoline is $2.186/gallon.

Now we have to determine the cost to buy 125 L of gasoline.

First we have to convert 125 L into gallon.

Conversion used:

(1 gallon =  128 oz, 1 oz= 29.6 mL, 1 mL = 0.001 L)

As, 1 L = 1000 mL

So, 125 L = 125000 mL

and,

As, 29.6 mL = 1 oz

So, 125000 mL = [tex]\frac{125000mL}{29.6mL}\times 1oz=4222.9oz[/tex]

and,

As, 128 oz = 1 gallon

So, 4222.9 oz = [tex]\frac{4222.9oz}{128oz}\times 1\text{ gallon}=32.9\text{ gallon}[/tex]

Now we have to determine the cost to buy 125 L of gasoline.

As, the cost of 1 gallon of gasoline = $2.186

So, the cost of 32.9 gallon of gasoline = $2.186 × 32.9

                                                                = $71.92

Therefore, the cost of pennies to buy 125 L of gasoline would be, $71.92

Answer: C

Explanation: They pasteurize the juice to make it safe to drink.

The sentence which uses pasteurization correctly is that they  pasteurize the juice to make it safe to drink.

Pasteurization or pasteurisation is a process of food preservation in which packaged and non-packaged foods (such as milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life. The process is intended to destroy or deactivate microorganisms and enzymes that contribute to food spoilage or risk of disease, including vegetative bacteria, but most bacterial spores survive the process.

The process is named after the French microbiologist Louis Pasteur whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine.Spoilage enzymes are also inactivated during pasteurization. Today, pasteurization is used widely in the dairy industry and other food processing industries to achieve food preservation and food safety.

Answer:

Explanation:

Ionization energy:

It is the minimum amount of energy required to remove the electron from isolated gaseous atom to make the ion.

As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell.

When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.  Where as,

When we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As the size of atom increases the ionization energy from top to bottom also  decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.

There are two forms of chemical equations

Ion equation: written in ion form (as separated ions) which forms the net ionic equation after removing an ion spectator

Molecular equation: written in molecular form

2AgNO₃(aq) + H₂S(aq) ⇒ Ag₂S(s) + 2HNO₃(aq)

The above reaction can be included in a double replacement reaction⇒ an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

It can be shown the existence of the precipitation reaction, which is the formation of insoluble Ag₂S (not dissolve)
