When you write a formula from a home you must follow these rules

1) Write down the name you must follow these rules

2)Write down the symbols for the elements and group in the compound of elements

3)Write down the valency

4)Adjust the number of atoms of each element or group valency is the combining capacity of elements with one another.

Imagine you are an astronaut and you travel to a planet with a much larger mass than Earth. How would this affect your weight? Explain your answer. (4 points)

Answers

Answer:

Explanation:

It may not make any difference. The information missing is the radius of the planet.

However for the purposes of the question, let us assume that it is roughly the same diameter of the earth. Then the weight of anyone would increase if the mass is all that changes..

The formula governing your weight is F = G * m1 *m2 / r^2. If m1 is the mass of the planet and it increases a lot then m2 (you) should increase.  The question is done by a proportion.

I am an alkali metal located in the third period of the periodic table. Who am I?

Answers

Answer:

Magnesium

Explanation:

It's an alkali metal and is in the third period on the period table. I'm sure

The alkaline earth metal found in period 3 of the periodic table is magnesium.The lightest structural metal is magnesium (Mg), an alkaline-earth metal from Group 2 (IIa) of the periodic table.

I am an alkali metal located in the third period of the periodic table. Who am I?

Six chemical elements in Group 1, the periodic table's leftmost column, make up the alkali metals.They are francium (F), cesium (Cs), rubidium (Rb), potassium (K), sodium (Na), and lithium (Li) (Fr). One of the chemical elements in the third row of the periodic table of the chemical elements is referred to as a period 3 element. Magnesium is regarded as a metal because it is a member of group2.Acid and metals react to produce salt and hydrogen gas.As a result, magnesium interacts with diluted hydrochloric acid to produce magnesium chloride (salt) and hydrogen gas. Magnesium is a silvery, light metal that makes up 2% of the Earth's crust but is not present in nature.Only in combination with other elements like carbon, calcium, and oxygen, as in the common mineral dolomite, could this versatile element naturally arise. Magnesium is a cofactor in more than 300 enzyme systems that affect a variety of biochemical processes in the body, including as protein synthesis, blood glucose control, blood pressure regulation, and muscle and nerve function [1-3].Magnesium is necessary for the oxidative phosphorylation, glycolysis, and generation of energy. Magnesium supports muscle and neuron function as well as energy synthesis in the body, among many other vital functions.Typically, low magnesium levels don't result in any symptoms.On the other hand, persistently low levels can raise your risk of osteoporosis, type 2 diabetes, high blood pressure, and heart disease. For the majority of individuals, daily doses under 350 mg are safe.The adverse effects of magnesium can include nausea, vomiting, diarrhea, and upset stomach in some people.Magnesium is POSSIBLY SAFE UNTIL TAKEN IN VERY HIGH AMOUNTS (more than 350 mg daily).

the following gases, which could it be?
A. Ne
B. CO
C. CO2
D. Kr

Answers

Answer:

Formula Weight of gas sample = 20.1 g/mole => Neon (Ne)

Explanation:

Use Ideal Gas Law formula to determine formula weight and compare to formula weights of answer choices.

PV = nRT = (mass/fwt)RT => fwt = (mass/Volume)RT = Density x R x T

Density = 0.900 grams/L

R = 0.08206 L·atm/mole·K

T = 0.00°C = 273Kfwt = (0.900g/L)(0.08206L·atm/mole·K )(273K)

= 20.1 g/mol => Neon (Ne)

(1) electron gain will result to a

Upon cooling this saturated copper sulfate solution, crystals of solid copper sulfate will be formed on the china dish.

How many protons,neutrons and electrons make a hydrogen atom

Answers

Explanation:

A hydrogen atom has an atomic number of 1.

So it's proton number will always be 1.

A neutral hydrogen atom does not have any charge.

So it has the same amount of electrons as protons, which turns out to be also 1.

A neutral hydrogen atom has an atomic mass of ≈1.00794amu≈1amu.

To find the amount of neutrons, we take the proton number and subtract it from the mass number.

1−1=0

So a neutral hydrogen atom has no neutrons.

In summary,

A hydrogen atom has

1 proton

1 electron

0 neutrons

another way of explaining:

The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons

Calculate the mass of iron formed when 299g of iron (ii) oxide is reduced by excess carbon monoxide

Answers

Answer:

Mass = 88.12 g

Explanation:

Given data:

Mass of iron oxide = 126 g

Mass of iron formed = ?

Solution:

Chemical equation:

Fe₂O₃ + 3CO    →      2Fe + 3CO₂

Number of moles of iron oxide:

Number of moles = mass/molar mass

Number of moles = 126 g/ 159.69 g/mol

Number of moles = 0.789 mol

Now we will compare the moles of iron with iron oxide.

                     Fe₂O₃           :             Fe

                        1                 :               2

                  0.789              :            2/1×0.789 = 1.578 mol

Mass of iron:

Mass = number of moles ×molar mass

Mass = 1.578 mol × 55.84 g/mol

Mass = 88.12 g

how many electrons does hydrogen need in order to have a full shell of valence electrons?

Answers

Answer:

One

Explanation:

In a hydrogen atom, the first outer shell only consists of two valence electrons, because it would already have one, the atom only needs one more.

It requires two electrons to completely occupy its outer shell, it frequently forms a single covalent bond with another atom. Because of this configuration, hydrogen can gain access to two electrons and completely occupy its valence shell.

What is Hydrogen?Hydrogen adheres to the duet rule because it only requires two electrons to completely occupy its valence shell. It deviates from the octet rule. Hydrogen only needs to form one bond. Because of this, H is always a terminal atom and never a central atom. Hydrogen is a chemical element with the symbol H and the atomic number 1.Hydrogen is the lightest element. Under normal conditions, hydrogen is a gas of diatomic molecules with the formula H2. It is colorless, odourless, tasteless, non-toxic, and extremely flammable. Hydrogen is a more environmentally friendly alternative to methane, also known as natural gas. It is the most abundant chemical element, accounting for 75% of the universe's mass. Water, plants, animals, and, of course, humans contain massive amounts of hydrogen atoms.
