The stoichiometry of the reaction shows that the mass of the precipitate is 7.15 g.
What is the amount of the precipitate formed?We know that the amount of the precipitate that is formed would depend on the stoichiometry of the reaction. This is why we have to set up the balanced reaction equation as follows;
[tex]AgNO_{3} (aq) + NaCl(aq) ----- > AgCl(s) + NaNO_{3} (aq)[/tex]
Number of moles of sliver nitrate = concentration * volume
= 50/1000 L * 1 M
= 0.05 moles
Number of moles of sodium chloride = 50/1000 L * 1 M
= 0.05 moles
Since the reaction is 1:1, the amount of the precipitate is;
0.05 moles * 143 g/mol
= 7.15 g

Calculate the pH for a 1.0 x 10-5 M solution of OH at 25°C.
pH = -log[H*), pOH = -log[OH-]
14 = pH + POH
0 pH = 11.00
0 pH = 9.00
0 pH = 6.00
0 pH = 3.00
Answer:
ph=9.00
Explanation:
Given 1.0x10^-15M of OH at 25c
first find Poh from Poh=-log[OH]
then Poh=-log[1.0x10^-5]
from above Ph=5
then find Ph from ph+poh =pw
where pw=14
so
ph+5=14
ph=9.00
The pH for a 1.0 x 10-5 M solution of OH at 25°C is 9.
What is pH?pH is a measure of acidity and basicity of aqueous solution. The range of pH goes from 0 - 14, with 7 being neutral. pH of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.pH is the measure of the relative amount of free hydrogen and hydroxyl ions in aqueous or other solutions.In water pH + pOH=14
pH = 14 - pOH = 14 - 5 = 9
From definition, pOH = - log₁₀ [OH⁻]
Thus pOH = -log₁₀ (1 x 10⁻⁵)
= - (-5) = 5
pH + pOH = 14
pH = 14 - pOH
= 14 - 5 = 9
pH = 9
Hence, pH = 9 is the correct answer.

explain why copper 2 oxide is a base although it does not turn litmus paper to blue
Answer:
See explanation
Explanation:
Copper II oxide is a base but not an alkali. An alkali is a soluble base. Since Copper II oxide is not soluble in water then it is not an alkali.
Let us recall that the change of colour of litmus with an alkali requires the presence of water. In the absence of water, solid Copper II oxide does not turn red litmus paper blue.
The ability to turn red litmus paper blue is commonly observed with alkalis and Copper II oxide is not an alkali.
Also recall that since Copper II oxide is not soluble, hydroxide ions are absent hence Copper II oxide does not turn red litmus paper blue.

H-C=C-H
ethyne CxHy
A. Unsaturated alkene
B. Unsaturated alkyne
O C. Saturated alkyne
O D. Saturated alkene
Answer:
Saturated alkyne
Explanation:
The hydrocarbons are known as the compounds which is made up of only carbon and hydrogen atoms. They may be saturated or unsaturated based on the number of bonds present. The molecule H-C≡C-H is an Unsaturated alkyne. The correct option is B.
The hydrocarbons in which the carbon and hydrogen atoms are connected through double or triple bonds are known as unsaturated hydrocarbons. Here ethyne is an unsaturated hydrocarbon.
Ethyne is an alkyne which have the C-C and C-H atoms connected through triple and single bonds.
Thus ethyne is option B.

(2 RIGHT CHOICES)
add a proton
add a neutron
add an electron
If you want to change the mass of your atom by 1 or more mass units, you can either? Add a proton and Add a neutron.
Explanation:
Option A and Option B is your answers.
To change the mass of your atom by more mass units ; you can add a proton or add a neutron ( A and B )
The nucleus of an atom is composed of a neutron and a proton while the outer shell of an atom comprises of the electrons.
The mass of an atom is dependent on the mass of the nucleus of the atom therefore to increase the mass of the atom by any number of mass units you can either add a proton or a neutron to the nucleus of the cell.
Hence we can conclude that to change the mass of your atom you can add a proton or add a neutron to the nucleus of the atom

PLEASE Answer asap! Compare two periodic families below. You must include at least two facts about each family. You may use any description of properties or periodic trends to help you.
Answer:
The alkali metals/group 1 are recognized as a group and family of elements. These elements are metals. Sodium and potassium are examples of elements in this family. Hydrogen is not considered an alkali metal because the gas does not exhibit the typical properties of the group. The largest family of elements consists of transition metals/group 3-12/group 3a. The center of the periodic table contains the transition metals, plus the two rows below the body of the table (lanthanides and actinides) are special transition metals. Even though both are metals, transition metals have higher melting points; they have higher density; they are less reactive with water; they react and form ions with different charges, but Group 1 metals only form 1+ ions.

A sports car requires 10 kg of 93 octane to fill the tank. How many grams of octane are in the tank when it is full?
Answer:
There are 10,000 grams of octane in the tank of the sports car when it is full
Explanation:
To solve this problem, we simply need to convert the mass of octane- 93 from kilograms to grams, using the standard conversion factor which is given below.
it will take 10kg of octane-93 to fill up the tank
1 kg = 1000grammes
therefore 10 kg = 10 X 1000 = 10,000 grams.
Hence, there are 10,000 grams of octane in the tank of the sports car when it is full.
