Answer:

The answer is C. "The metal to the left of phospherus in the same row"

Explanation:

It says that phospherus has a higher atomic radius than the other unkown element. But it has different characteristics compared to phospherus. So that means that it would not be able to be in the same row because elements in the same row share the same charectoristics. And since we want its atomic radius to be lower than phospherus, it would have to be to the  left of it because reading left to right all atomic numbers, mass, and radius gets higher

Please let me know if my reasoning was correct!! :)

Answer:

plum pudding model is the name of JJ. Thomson's experiment

explanation

Summary. J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup."

Answer:

J.J Thompson's experiment is

plum pudding model.

Answer:

P = 795.77 Mpa

Explanation:

Given that,

Force exerted by the hammer, F = 10⁴ N

The nail can be considered as a circle with radius of [tex]2\times 10^{-3}\ m[/tex]

We need to find the pressure exerted on the wall. Pressure is equal to force acting per unit area. So

[tex]P=\dfrac{F}{A}\\\\P=\dfrac{10^4\ N}{\pi \times (2\times 10^{-3})^2}\\\\P=795774715.45\ Pa[/tex]

We know that, 1 MPa = 1000000 Pa

So, P = 795.77 Mpa

So, the pressure exerted on the wall is 795.77 Mpa.

answer:

heterogenous mixture

Explanation:

Gravels can be broken down into different kinds of substances by physical processes because they are heterogeneous mixtures.

Gravels are generally made from different rock fragments including sandstone, limestone, and basalt. The rock fragments can be sorted out by physical means.

In other words, gravels are mixtures of different rocks but the individual rocks still maintain their identities in the mixture. Such mixtures are known as heterogeneous mixtures.

Answer:

silver chloride I think i'm not totally sure

Explanation:

The substance which represents the precipitate is silver chloride, AgCl.

•Silver nitrate (l)

•Sodium chloride (l)

•Silver chloride (s)

•Sodium nitrate (l)

A precipitate is a substance obtained from a reaction that is insoluble.

•Silver nitrate (l) => AgNO₃ (l)

•Sodium chloride (l) => NaCl (l)

•Silver chloride (s) => AgCl (s)

•Sodium nitrate (l) => NaNO₃ (l)

AgNO₃(l) + NaCl (l) —> AgCl(s) + NaNO₃(l)

From the balanced equation above, we can see that AgCl is in solid form.

Thus, the precipitate from the reaction is Silver chloride, AgCl.

Answer:

7 * 10^9 atoms

Explanation:

We must first find the number of atoms originally present. We can do this by considering the information given in the question that one-eight of the original isotope is left and that is about one billion atoms of the original material left. Let the number of atoms originally present be x.

So;

1/8x = 1 * 10^9

x = 8/1 * 1 * 10^9

x = 8 * 10^9 atoms of radioactive material.

Number of atoms of daughter nucleus present=

x- 1/8x = 7/8x

but x = 8 * 10^9 atoms of radioactive material

Therefore;

7/8 * 8 * 10^9 atoms = 7 * 10^9 atoms

Answer:

Coefficients

Explanation:

Balancing a chemical equation entails making sure that the number of atoms on the reactant side equates that on the products side. According to this question, Charlie is trying to balance an equation. She has identified and counted the number of each atoms in the reactants and products side.

However, to ensure that the identified atoms are equal on both sides of the equation, Charlie needs to adjust the COEFFICIENTS of necessary molecules/atoms. Coefficients are numbers used to multiply an algebraic term. For example, 2CO2 means coefficient 2 will be used to multiply each atom in the carbon dioxide molecule. Based on this explanation, the balanced forms of the equations in the question are:

1. FeCl3 + 3NH4OH → Fe(OH)3 + 3NH4Cl

2. CH4 + 2O2 → CO2 + 2H2O

3. 2Fe + 3H2SO4 → Fe2(SO4)3 + 3H2

4. PCl5 + 4H2O → 5HCl + H3PO4

The basic unit of chemistry is atom.

Matter is all what is present around. Atoms and compounds are all made of very small parts of matter. Matter is defined as anything that has mass and takes up space (it has volume).

Atoms are the smallest unit of matter. It has a tiny atomic nucleus, which is in the center of the atom and contains positively charged particles called protons and neutral, uncharged, particles called neutrons. On the outer side of the atom is a “cloud” of electrons which are negatively charged particles that orbit around the nucleus.

#SPJ1

Answer:

liquid

Explanation:

There are three states of matter and these are the following:

1. Solid

2. Liquid

3. Gas

"Liquid" has particles that show movements in-between to that of the solid and liquid. The forces between these particles are weaker when compared to the forces of particles in solid. This allows it to take the shape and volume of the container without actually changing its volume. If you pour a liquid unto a heart-shape container, it will take the shape of the heart as its form (it has no fix shape).

Explanation:

The summary of the question is about water molecules and it's properties. It is made up of two hydrogen atoms and one atom of oxygen. Water molecule is polarized to some extent due to the high electronegativity of oxygen. Some of the physical properties of water includes:

--> it is colourless, odourless and tasteless liquid.

--> Boiling point of water is 100°C while the melting point is 0°C.

--> It is denser than ice.( Ice floats on top of water).

--> Usually described as a universal solvent due to its ability to dissolve many substances.

Explanation:

Given

speed of light=v=1.86 x 10⁵ miles/s

time=1 s

Required

distance of light travel

Solution

The motion of light can be considered as motion that has a constant velocity so that it can be classified as a straight, regular motion that has no acceleration

Can be formulated

[tex]\tt \boxed{\bold{d=v\times t}}}[/tex]

For the distance traveled by light in the above problem becomes:

[tex]\tt d=1.86\times 10^5~miles/s\times 1~s\\\\d=\boxed{\bold{1.86\times 10^5~miles}}}[/tex]

Explanation:

Nonpolar compounds do not dissolve in water. The attractive forces that operate between the particles in a nonpolar compound are weak dispersion forces. However, the nonpolar molecules are more attracted to themselves than they are to the polar water molecules.
