It increases the hydronium ions

make me brainliest plz
Lelechka [254]3 years ago

Answer:

B. Decrease

Explanation:

 Base  dissociate to give  out  OH-  ions

 In the other hand ,when  water (H2O)   dissociate it  give out hydronium ions ( H3O+)    and OH- ions

when  base  is added to  water  more OH-   it  led  to  addition of more Oh- ions  hence  H3O+ decrease.

A solution contains 0.115 mol h2o and an unknown number of moles of nacl. the vapor pressure of the solution at 30°c is 25.7 tor
Valentin [98]
According to Raoult's low:
We will use this formula: Vp(Solution) = mole fraction of solvent * Vp(solvent)
∴ mole fraction of solvent = Vp(Solu) / Vp (Solv)
when we have Vp(solu) = 25.7 torr & Vp(solv) = 31.8 torr 
So by substitution:
∴ mole fraction of solvent = 25.7 / 31.8 =0.808 
when we assume the moles of solute NaCl = X 
and according to the mole fraction of solvent formula:
mole fraction of solvent = moles of solvent / (moles of solvent + moles of solute)
by substitute:
∴ 0.808 = 0.115 / (0.115 + X)
 So X (the no.of moles of NaCl) = 0.027 m

Describe how you could prove that a bicycle is matter
Ainat [17]

Answer:

Explanation:

Matter is anything that has weight and occupies space.

To prove that a bicycle is a matter, we need to show that it has weight and will occupy space.

When you put the bicycle on a weighing scale, you will see the weight of the bicycle. This a proof that bicycle is a matter.

To show that the bicycle can occupy space, place the device in a tank full of water. From the tank, the bicycle will displace some water. Substances that cannot occupy space will not behave in such manner.

If the H+ in a solution is 1x10^-1 mol/L what is the OH-
damaskus [11]
PH scale is used to determine how acidic or basic a solution is.
we have been given the hydrogen ion concentration. Using this we can calculate pH,
pH = - log[H⁺]
pH = - log (1 x 10⁻¹ M)
pH = 1
using pH can calculate pOH
pH + pOH = 14
pOH = 14 - 1
pOH = 13
using pOH we can calculate the hydroxide ion concentration 
pOH = - log [OH⁻] 
[OH⁻] = antilog(-pOH)
[OH⁻] = 10⁻¹³ M
hydroxide ion concentration is 10⁻¹³ M

Ionic bonds Select one: a. result from sharing electrons. b. result from transferring electrons. c. result from like charge attr
Naddika [18.5K]
<h2>Ionic bonds result from transferring of electrons</h2>

Explanation:

  • Ionic bonds result from transferring of electrons.
  • An ionic bond is also referred to as an electrovalent bond.
  • The main reason for the formation of the bond is an electrostatic attraction between oppositely charged ions that are cation and anion in a chemical compound.
  • The formation of such bonds occurs when the valence (outermost) electrons of one atom are transferred to another atom or the loss of electrons from one atom and gain of electrons of another atom.
  • The atom that loses the electrons forms cation that is a positively charged ion.
  • The atom that gains electrons forms an anion that is a negatively charged ion.
