I believe is the npp i kinda forgot how to do these lol

Diagram with npp type shows an atom that is not a form of hydrogen.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Answer:

Yes, that is correct!

Explanation:

Answer:

Yes

Explanation:

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

Answer:

nucleus as electrons are being added to the same principal energy level. These electrons are gradually pulled closer to the nucleus because of its increased positive charge. Since the force of attraction between nuclei and electrons increases, the size of the atoms decreases.

Explanation:

Nuclear attractive pull to the electrons results in smaller atomic radius. Two reasons that leads the size of an atom smaller by electron loss are nuclear pulling and emptying outermost orbital.

The nucleus have a net positive charge and electrons are negative in charge, thus, each electron experience a nuclear attractive pull. However, each electrons are shielded slightly from this attraction by the surrounding electrons.

The reasons which make the atomic radius smaller are the following.

Therefore, due the two reasons mentioned above, the atomic radius reduces by electron loss.

Answer:

I believe it's j, convergent plate boundaries

The type of plate boundary that forms snowy mountains are convergent plate boundaries. option J is correct.

The convergent plate boundaries are which consist of two plates that move toward each other which results in the process called collision of two plates with each other.

The snowy mountains are full of snow which melts due to the change in temperature and leads to the formation of different plates and boundaries and the collision of two continental plates leads to the formation of this.

Therefore, option J is correct, the type of plate boundary that forms snowy mountains are convergent plate boundaries.

Explanation:

I had that question too.

The % yield of Ca(OH)₂ : 62.98%

Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

CaO + H₂O ⇒ Ca(OH)₂

mass CaO= 4.2 g

mol CaO(MW=56,0774 g/mol) :

[tex]\tt mol=\dfrac{mass}{MW}\\\\mol=\dfrac{4.2}{56,0774 g/mol}\\\\mol=0.075[/tex]

mol Ca(OH)₂ based on mol CaO

mol ratio CaO : Ca(OH)₂,= 1 : 1, so mol Ca(OH)₂ = 0.075

mass Ca(OH)₂(MW=74,093 g/mol) ⇒ theoretical

[tex]\tt mass=mol\times MW\\\\mass=0.075\times 74,093 g/mol\\\\mass=5.557~g[/tex]

% yield :

[tex]\tt =\dfrac{actual}{theoretical}\times 100\%\\\\=\dfrac{3.5}{5.557}\times 100\%\\\\=62.98\%[/tex]

Answer: 4g/cm^3 or 4000g/L (4kg/L)

Explanation:

I'm not sure what units the question intended so I put both. For the first one, the equation for density is mass/volume so I divided the 20g by 5cm^3 to get 4g/cm^3. Just in case those aren't the intended units for volume and is instead liters, one cm^3 equals one ml. In addition, there are 1000ml in every liter so you can determine the amount per liter by multiplying 4g/ml by 1000 to get 4000g/L or 4kg/L.

Answer:

The name of the two parts found on the left side of the equation is reactants.

Explanation:

Chemical reaction is the way one substance reacts against another. That is, a chemical reaction is that chemical process in which two or more substances, by the action of an energy factor, are converted into other substances. The new substance (s) that are formed usually present a totally different appearance from that of the starting substances.

In a chemical reaction there are the substances that react, that is, the reactants, and the substances produced, called products.

A chemical reaction is represented by a chemical equation. The formulas of the reactants are written on the left, and those of the products on the right, both separated by an arrow indicating the direction of the reaction.

Reactants ⇒ Products

Then, the name of the two parts found on the left side of the equation is reactants.

Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours. Calculate the percentage of time spent in each phase by counting the total number of cells in each phase (total in interphase, in prophase, etc.) and dividing each by the total number of cells you counted. How do cancer cells differ in total time required for mitosis? Cancer cells produce 117 minutes faster than regular cells. ... Normal cells require 640 minutes during interphase, cancer cells only need 380. For prophase, cancerous cells need 15 minutes less than regular cells. Another hallmark of cancer cells is their "replicative immortality," a fancy term for the fact that they can divide many more times than a normal cell of the body. In general, human cells can go through only about 40-60 rounds of division before they lose the capacity to divide, "grow old," and eventually die 3.
