Relative atomic mass(Ar) : A=7, G=16

The empirical formula : A₂G

Given

3.5g of element A

4.0g of element G

Required

the empirical formula for this compound

Solution

The empirical formula is the smallest comparison of atoms of compound forming elements.

The empirical formula also shows the simplest mole ratio of the constituent elements of the compound

mol of element A :

[tex]\tt mol=\dfrac{mass}{Ar}\\\\mol=\dfrac{3.5}{7}=0.5[/tex]

mol of element G :

[tex]\tt mol=\dfrac{4}{16}=0.25[/tex]

mol ratio A : G = 0.5 : 0.25 = 2 : 1

Answer:  7.00 L

Explanation:

Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

[tex]P\propto \frac{1}{V}[/tex]     (At constant temperature and number of moles)

[tex]P_1V_1=P_2V_2[/tex]  

where,

[tex]P_1[/tex] = initial pressure of gas  = 42.0 mm Hg

[tex]P_2[/tex] = final pressure of gas  = 75.0 mm Hg

[tex]V_1[/tex] = initial volume of gas   = 12.5 L

[tex]V_2[/tex] = final volume of gas  = ?

[tex]42.0\times 12.5=75.0\times V_2[/tex]  

[tex]V_2=7.00L[/tex]

Therefore, the volume  when the pressure has increased to 75.0 mm Hg is 7.00 L

Explanation:

They are both in shell 5 and subshell s.

Since s only has 1 orbital, they also have the same orbital number.

But they have different magnetic spins.

Hence 3 out of 4 quantum numbers are in common.

Answer:

Lowering activation energy of a reaction.

Explanation:

Activation energy is the minimum amount of energy required by the reactants just to be converted to products.

Since catalysts increase the rate of reaction, activation complex is reached in short period of time hence activation energy is lowered.

Explanation:

Answer:

Soap breaks up the oil into smaller drops, which can mix with the water.

Explanation:

This works because soap is made up of molecules with two different ends.

The soap molecules works as a surfactant for the water oil interphase. The hydrophobic head of the soap molecules trap the oil and dirt ad remove from the surface.

Surfactants are chemical substances used to reduce the interfacial tension between substance boundary. Soaps and detergents acts as surfactants which are used to remove the dirt and oil from material surface.

Soap has both polar and non-polar characteristics. The alkaline part  in the soap causes it to have a polar head, and because of the electric charge on this head, the soap is hydrophilic. A hydrophilic part of soap is drawn to water and will cling to it.

In this instance, the positive-charged hydrogen atoms of the water's hydrogen atoms match with the polar head of the soap molecule. The other part of soap is a fatty acid tail, which is hydrophobic and can bind with the oil and dirt. The trapped oil molecules are then be removed by water.

Answer:

Hurricanes are the most violent storms on Earth. They form near the equator over warm ocean waters. Actually, the term hurricane is used only for the large storms that form over the Atlantic Ocean or eastern Pacific Ocean. The generic, scientific term for these storms, wherever they occur, is tropical cyclone.

Explanation:

Since iron is a metal and oxygen is a non metal, a bond is formed between the two when electrons are transferred from iron to oxygen. Hence the bond is ionic.

Two silver atoms are held together by metallic bonds. Metallic bond are bond forces that exist between metal atoms in a crystal lattice. The valence electrons in this bond form a cloud. Metals have low ionization energy and low electronegativity hence they loose electrons easily. This accounts for the nature of the metallic bond.

The bond formed between two chlorine atoms is a covalent bond. The valence electrons in this bond are localized between the two chlorine atoms. Chlorine is a nonmetal hence it has a high ionization energy and high electronegativity. Hence it forms covalent bonds in which electrons are shared between bonding atoms.

✔ desert

✔ semiarid

✔ steppes

.

Explanation:

The deserts and steppes comprise the regions that are characterized by dry climates. The dry climates are characterized by very little rainfall, hot summers, and mild winters. The correct option is B.

The areas which are very dry and where the water escapes and leaves the area drier than other places is known as the dry climate. Most dry climates have summers very hot, winters cool and warm and the air is very dry.

The main characteristic feature of the dry climate is the low and infrequent rainfall. Arid and semi desert areas have only about 35 cm rainfall per year.

Thus the correct option is B.

Explanation:

There are multiple to find power:

The question did not state the speed at which the arm of the chipmunk moves. However, the question did state the work done ([tex]W = 0.70\; \rm J[/tex]) and the time required ([tex]t = 2\; \rm s[/tex]).

Therefore, the equation [tex]P = W / t[/tex] seem to be more suitable.

[tex]\begin{aligned}&P\\ &= \frac{W}{t} \\ &= \frac{0.70\; \rm J}{2\; \rm s} \approx 0.35\; \rm W\end{aligned}[/tex].

Significant figures:

The given measurement have four significant figures 1234.

All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.

Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.

Zero between the non zero digits are consider significant like 104 consist of three significant figures.

The zeros at the right side when decimal point is present e.g 2400. are also significant. There are four significant figures are present.

a) 0.003 L

This measurement have 1 significant figure which is 3.

b) 140 g

This measurement have 3 significant figure  1, 4. In this measurement 0 is trailing zero that's why it is not consider significant.
