Answer: The question is incomplete and the options are not given but here are d options from another website.

a. Electronegativity increases as you move to the right of the periodic table.

B. Electronegativity is the ability of an atom to attract electrons.

c. A very electronegative atom easily gives up electrons.

d. Electronegativity increases with a decreased number of protons.

The correct options are

a. Electronegativity increases as you move to the right of the periodic table.

B. Electronegativity is the ability of an atom to attract electrons.

d. Electronegativity increases with a decreased number of protons.

Explanation:

This is because Electronegativity is the ability of an element to attract pair of electrons to itself.

Electronegativity increases as a result of increase in protons and when there is more electron pull.

As, the size of an element decreases, the valence electrons are attracted near to the nucleus. Therefore, there is increase in attraction between shared electron and nucleus.

Answer and Explanation:

Solutions that have a pH of 8 would be considered a Weak Base.

This is because a weak base is a base that, upon dissolution in water, does not dissociate completely.

Solutions/liquids that have a pH higher than a pH of 7 are basic solutions, while solutions/liquids that have a pH lower than a pH of 7 are acidic solutions.

When the pH level is closer to 7, it is weak, and when it is far from 7, like if it is 1 or 12, then it is a strong acid/base.

Explanation:

Answer:

To find the mass percent of hydrogen in hydrogen chloride, we must divide the weight of the hydrogen atom alone by the weight of the entire molecule. Then we multiply by 100% to find the percentage. Thus, 2.77% of the mass of hydrogen chloride is hydrogen.

Answer:

4/15

Explanation:

we can write out an equation by doing (1/5 ÷ 3/4) and then switch the sign to multiplication and we can keep the first fraction the same (in this case 1/5) and then we flip the second fraction BUT when we flip the second fraction upside-down we have to change the symbol to multiplication (1/5x4/3)

then after that all we do is multiply the denominators and numerators :)

Answer: 1. [tex]2Al+3CuCl_2\rightarrow 2AlCl_3+3Cu[/tex]

2. 3 moles of [tex]CuCl_2[/tex] : 2 moles of [tex]Al[/tex]

3. 0.33 moles of [tex]CuCl_2[/tex] : 0.92 moles of [tex]Al[/tex]

4. [tex]CuCl_2[/tex] is the limiting reagent and [tex]Al[/tex] is the excess reagent.

5. Theoretical yield of [tex]AlCl_3[/tex] is 29.3 g

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} Al=\frac{25.0g}{27g/mol}=0.92moles[/tex]

[tex]\text{Moles of} CuCl_2=\frac{45.0g}{134g/mol}=0.33moles[/tex]

The balanced chemical equation is:

[tex]2Al+3CuCl_2\rightarrow 2AlCl_3+3Cu[/tex]  

According to stoichiometry :

3 moles of [tex]CuCl_2[/tex] require = 2 moles of [tex]Al[/tex]

Thus 0.33 moles of [tex]CuCl_2[/tex] will require=[tex]\frac{2}{3}\times 0.33=0.22moles[/tex]  of [tex]Al[/tex]

Thus [tex]CuCl_2[/tex] is the limiting reagent as it limits the formation of product and [tex]Al[/tex] is the excess reagent.

As 3 moles of [tex]CuCl_2[/tex] give = 2 moles of [tex]AlCl_3[/tex]

Thus 0.33 moles of [tex]CuCl_2[/tex] give =[tex]\frac{2}{3}\times 0.33=0.22moles[/tex]  of [tex]AlCl_3[/tex]

Theoretical yield of [tex]AlCl_3=moles\times {\text {Molar mass}}=0.22moles\times 133.34g/mol=29.3[/tex]

Thus 29.3 g of aluminium chloride is formed.

Answer: Hotspot: A hotspot is a physical location where people can access the Internet, typically using Wi-Fi, via a wireless local area network (WLAN) with a router connected to an Internet service provider. ... While many public hotspots offer free wireless access on an open network, others require payment.

A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.
