Answer:

1 × 10^-11 units.

Explanation:

Given:

[H+] = 1 × 10^-2

pH = - log [H+]

= -log [1 × 10^-2]

= 2

The question further said, "which raises the ph of the fluid by one unit"

pH(new) = 2 + 1

= 3

pH + pOH = 14

pOH = 14 - 3

= 11

pOH = - log [OH-]

[OH-] = 10^-11

= 1 × 10^-11 units

Answer:

[OH⁻] = 1 × 10⁻¹¹ mol/dm³

Explanation:

Since the hydronium ion concentration of the gastric fluid is [H₃O]⁺ = 1.0 × 10⁻².

The pH at this point is pH = -log₁₀[H₃O]⁺ = -log₁₀[1.0 × 10⁻²] = 2

When milk of magnesia is added, the pH increases by one unit, so the new pH is 1 + 2 = 3

Since pH + pOH = 14, then pOH = 14 - pH = 14 - 3 = 11

The hydroxide ion concentration of the fluid is gotten from

pOH = -log₁₀[OH⁻]

11 = -log₁₀[OH⁻]

-11 = log₁₀[OH⁻]

taking antilog

[OH⁻] = 1 × 10⁻¹¹ mol/dm³

How can water boil without heat?​
kaheart [24]

Answer:

Put water at room temperature into a vacuum chamber and begin removing the air. Eventually, the boiling temperature will fall below the water temperature and boiling will begin without heating. Or if you want to be easy but messy, add dry ice to a bowl of water and watch how the water starts to boil.

A helicopter is traveling at 86.0 km/h at an angle of 35° to the ground. What is the value of Ax? Round your answer to the neare
arsen [322]

First thing plot a right angle with angle of elevation of 35degrees as shown in figure then use SOHCAHTOA.

Ay/Helicopter = sin 35

Ay = 86 sin 35 = 36.8237

Ax/Helicopter = cos 35

Ax = 86 cos 35 = 77.7175

Note: I ignore the negative signs coz they signify direction

What does it mean to say that the protons give the atom is identity
Salsk061 [2.6K]

The number of protons tells you what element an atom is. Just knowing the number of neutrons/mass number does not tell you what element an atom is, since atoms of the same element can have different mass numbers. But all atoms with the same number of protons, are also always of the same element.

Hence, we can identify an atom by the number of protons it has
