How do the number of protons in an atom affect the atom's
identity?

Answers

Answer:

The number of protons in an atom define each individual element because the number of protons is the atomic number which is the defining property of an atom and never changes. The number of protons determines an atom's identity. For example, Oxygen has an atomic number of 8, so it has 8 protons, so no matter what ionic compound or molecule it's part of, every single Oxygen atom will always have 8 protons each.

What is lunar phase ?

Lunar phase is the phase of moon which is viewed from the earth, the lunar phase is also known as moon phase is a shape of moon's directly sunlit portion and it can be expressed quantitatively.The current moon phase for today is the new moon phase.The moon is known as earth's only natural satellite and combinedly with earth it forms the earth-moon satellite system.

The size of moon is one quarter of earth in diameter. It is fifth largest satellite in the solar system. The distance of moon from earth is 384,400 km. The radius of moon is 1,737,4 km.  The gravity of moon is 1.62 m/sec^2.

The total surface area of moon is 3.793×10^7 km square and it's surface pressure is 10^-7 Pascal.There are total 8 phase of moon and these are new moon, first quarter, waxing gibbous, third quarter and waning crescent.

Therefore,Pluto's average distance from the Sun is about 3,666,000,000 miles and in inches it is 2.3227776e+14.

Mrs. Grogan wants to know if she is packing the same amount of animal crackers for her son’s snack each day.

She fills up a sandwich bag full of animal crackers each day. Mrs. Grogan takes the mass of the animal crackers and discovers that she uses 23.4 g, 25.2 g, 24.3g, 24.4 g, and 24.8 g of animal crackers for each day during the week. Convert the average mass into kilograms and record your answser to the correct number of significant figures. NO UNITS!

Answers

Answer: 0.02442 with 5 s.f. Explanation: (23.4g +25.2g +24.3g + 24.4g +24.8g)/5 = 24.42g. 1000g/kg so 24.42g = 0.02442 kg

Imagine you need to explain to a friend how to convert a value on a food label to one that is measured in grams. Assume the package of food has a mass of 1.0 pounds. write an explanation for how to use dimensional analysis to convert this value to one expressed in grams.

Answers

Answer:

453.592 grams

Explanation:

Given

Mass = 1 lb

Required.

Convert to grams using dimensional analysis

Represent 1 lb with x g

In unit conversion, we have that.

1 lb = 453.592 g

So:

Getting the equivalent of lb in g, we have:

x g = 1 lb * (453.592 g/ 1 lb)

x g = 1 * 453.592 g

x g = 453.592 grams

Hence:

The equivalent of 1 lb in grams is 453.592 grams

difference between halogens and group 0 elements

Answers

Answer:

Colourless. Although they have similar properties they are not identical. For example, as you descend Group 0 the density of the gas increases as does the mass of a single atom. ... All the halogens exist as molecules, bonding covalently to their own atoms - adding stability as they complete their full outer shells.

The difference between halogens and group 0 elements is that in their electronic configurations the halogens have 1 electron less than the stable octet while the zero group elements have stable octet.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

a beaker contains 0.250 l of liquid. a student pours 0.00385 L of liquid out of the beaker. How much liquid remains in the beaker? choose the value reported with the correct number of significant figures

Answers

Answer:

The volume of the liquid remaining in the beaker is 0.24615 l

Explanation:

The initial volume of liquid in the beaker = 0.250 l

The volume of liquid the student pours out of the beaker = 0.00385 l

The volume of liquid remaining in the beaker, V, is given as follows;

V = The initial volume of liquid in the beaker - The volume of liquid the student pours out of the beaker

Therefore, we have;

V = 0.250 l - 0.00385 l = 0.24615 l

The volume of the liquid remaining in the beaker is 0.24615 l.

How do you determine the charge of an isotope?

Answers

Answer:

If the protons in the atom outnumber the  electrons, the isotope has more positive charges than negative charges but If the number of electrons exceeds the number of protons, the ion charge will be negative.

Explanation:

The charge of an isotope is defined by how many more protons there are than electrons.

Or the other way around.

For example if there are 4 protons and 2 electrons, the ion charge is +2 because there are more protons.

If there are 4 electrons and 2 protons, the ion charge is -2 because there are more electrons.

Calculate the mass of oxygen needed to react 10g of calcium to form calcium oxide. 2 Ca + O2→2 CaO

Answers

Answer:

Explanation:

1122 g CaO.

I hope I helped you! :)

The mass of oxygen needed to react 10 grams of calcium to form calcium oxide is 4.0 grams.

Given:

The reaction:

[tex]2Ca+O_2\rightarrow CaO[/tex]

Mass of calcium = 10 g

To find:

The mass of oxygen needed to react 10 grams of calcium to form calcium oxide.

Solution:

[tex]2Ca+O_2\rightarrow CaO[/tex]

Mass of calcium = 10 g

Moles of calcium = [tex]\frac{10 g}{40.078 g/mol}=0.25 mol[/tex]

According to reaction, 2 moles of calcium reacts with oxygen, then 0.25 moles of calcium will react with:

[tex]=\frac{1}{2}\times 0.25 mol=0.125 \text{ mol of }O_2[/tex]

Mass of 0.125 moles of oxygen gas:

[tex]0.125 mol\times 31.998 g/mol=3.99975 g\approx 4.0 g[/tex]

The mass of oxygen needed to react 10 grams of calcium to form calcium oxide is 4.0 grams.
