HF +NaOH --------> NaF + H₂O is the net ionic equation for the reaction between HF (a weak acid) and NaOH.
When hydrogen fluoride and sodium hydroxide react, sodium fluoride and water are produced. The reaction is an acid-base neutralization reaction and is often used to produce a buffer solution.
Hydrogen fluoride is a very strong acid and sodium hydroxide is a very strong base, so when they react, they produce a salt (sodium fluoride) and water.
The reaction is exothermic and produces a lot of heat, so it is important to use a large excess of sodium hydroxide to ensure the reaction is complete and that the heat is dissipated.
The reaction also produces a large amount of hydrogen gas, which can be dangerous if not vented properly. In summary, when hydrogen fluoride and sodium hydroxide react, sodium fluoride and water are produced, along with a lot of heat and hydrogen gas.
The net ionic equation is as follows:

Our final response will be 2.33 grams because this is gramper mole and cancel this.We consequently just require 2.33 g of nickelori to create our solution.
Find the solution ?In order to create our accua solution, which has a concentration of 0.193 molaso, we are figuring out how much nicephoride is needed.It's important to keep in mind that molarity is equal to a small number of moles of solution multiplied by the volume of solution that should be in the thirst.As a result, we multiply the solution's molarity by 0.19 feet and plug in the volumes to find the amount of moles of nikosfluoride.When we convert them to ethereal, 1 beacon will be able to cancel, therefore this is moleplitere multiplied by the volume of the solution, which is 125 l.We have 0.0241, and the remaining units are moles.Since we're trying to solve for mass in this case, we need to multiply as we have the number, and the 2 will be converted to 0.241. This is an emu mole.This result is the product of the number of moles and the molar mass of nikochloride.That makes 96.69.Our final response will be 2.33 grams because this is gramper mole and cancel this.We consequently just require 2.33 g of nickelori to create our solution.To learn more about molarity refer

what is the mass of agno3 that is present in 'solution 3'? (please use three significant figures for your answer) grams.
The mass of AgNO₃ present in the given solution will be 5.31grams.
The molality is defined as moles of solute, which in your case is silver nitrate, per kilogram of the solvent. This means that the solution's molality essentially tells about the number of moles of solute present in 1 kg of solvent.
In this case, a 0.250 molal solution would contain 0.250 moles of solute for every 1 kg of solvent. The problem tells that we have 125 g of solvent available. Using the solution's molality as a conversion factor to calculate how many moles of silver nitrate it must contain and we should not forget to convert the mass of solvent from grams to kilograms
Now, we know that silver nitrate has a molar mass of 169.87 g mol⁻¹, which means that the one mole of silver nitrate has a mass of 169.87 g

Suppose 0.317 g of barium nitrate is dissolved in 150. mL of a 16.0 m M aqueous solution of ammonium sulfate.
Calculate the final molarity of nitrate anion in the solution. You can assume the volume of the solution doesn't change when the barium nitrate is dissolved in it.
Be sure your answer has the correct number of significant digits.
Need help! Thank you, looked at other examples and I am getting them all wrong.
Molar concentration of nitrate anions in solution of 0.317g of barium nitrate is dissolved in 150. mL of a 16.0mM aqueous solution of sodium chromate is 0.0032
Since the nitrate ion is NO₃⁻ and barium comes from group 2, it forms the ion Ba²⁺, so the formula for barium nitrate is:
Ba(NO₃)₂. The molar mass is:
137 g/mol, N = 14 g/mol, O = 16 g/mol, so the molar mass of barium nitrate is
137 + 2x(14 + 3x16) = 199 g/mole
The number of moles is the mass divided by the molar mass, so:
n = 0.317/199 = 0.0016 mol Ba(NO₃)₂.
One mole of salt contains 2 moles of NO3-, so the number of moles of nitrate is 0.0032 moles. and the nitrate formed is completely water soluble. Therefore, the number of moles of nitrate remains is 0.0032 moles.
Molarity is the number of moles divided by the volume (0.15 L).
[NO₃⁻] = 0.0032/0.15 = 0.0032
Therefore, molar concentration of nitrate anions in solution of 0.317g of barium nitrate is dissolved in 150. mL of a 16.0mM aqueous solution of sodium chromate is 0.0032

Which option best describes something that causes ionic bonds to form?.
The option that best describes something that causes ionic bonds to form is the transfer of electron(s) from a metal to a nonmetal.
An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom that islosing one or more electrons becomes a cation which is a positively charged ion. The atom that is gaining one or more electron becomes an anion which is a negatively charged ion.
Metals are electropositive in nature and they tend to lose electrons, whereas nonmetals are electronegative and tend to gain electrons. A metal atom loses one or more electrons to form a cation with an octet. The same number of electrons are then accepted by the appropriate number of atoms of a nonmetal to form an octet in the anion, producing an ionic compound.
So for an ionic compound there is transfer of electron(s) from a metal to a nonmetal.

The sum of all the individual partial pressures of each gas collectively gives the total pressure of the mixture of gases.
Given that, a tank contains :
helium gas at 490 mmhg
nitrogen gas at 0.75 atm
neon at 520 torr
To find: Total pressure in atm
∵ P(total) = P(He) + P(N₂) + P(Ne)
we know that,
760 mm Hg= 1 atm= 760 torr
now, we will convert the units of partial pressures of each gas to atm.
P(He)= [tex]\frac{490 torr}{760 torr/atm}[/tex] = 0.645atm
P(Ne) =[tex]\frac{520 torr}{760 torr/atm}[/tex]=0.684
P(N₂) = 0.75 atm
sum of the partial pressures will give the total pressure i.e
P(total) =(0.645+0.684+0.75)atm
