A balloon is filled with 35.0 L of helium in the morning when the temperature is 20.00 Celsius by noon the temperature has risen
Lubov Fominskaja [6]
Given
V1 = 35L
T1 = 20.00 C = 293.0 K
V2 = ???
T2 = 45 C = 318 C

Formula
V1/T1 = V2/T2

Sub and Solve
45/293 = x / 318 Cross multiply
45*318 = 293x Divide by 293
45*318/293 = x
14310 / 293 = x
x = 48.84

What is the approximate pH of a .06 M solution of CH3COOH given that Ka= 1.78*10-5
Step2247 [10]
CH₃COOH ⇔ CH₃COO⁻ + H⁺

[CH₃COO⁻] = [H⁺] = x

K=\frac{|CH_{3}COO^{-}|*|H^{+}|}{|CH_{3}COOH|}=\frac{x^{2}}{|CH_{3}COOH|}\\\\
1,78*10^{-5}=\frac{x^{2}}{0,06} \ \ |*0,06\\\\
0,1068*10^{-5}=x^{2}\\\\
x_{1}\approx0,001 \ \land \ \ x_{2}=\approx-0,001\\\\
pH=-log|H^{+}|=-log0,001=3

A person suffering from hyponatremia has which of the following?
Katen [24]

d. Too little sodium in the bloodstream.

Explanation:

A person suffering from hyponatremia can be said to have too little sodium in their bloodstream. The word hyponatremia stems from two latin words:

                   hypo - low

                   natrium - sodium

  •   A person suffering from this condition will lack thinking capabilities.
  • Na, K and Mg are electrolytes in the body that helps to transmit electrical impulses.
  • A person might feel nauseated, lack balance if they suffer from this illness.
  • Hyponatremia can be caused by too much fluid in the body which can readily dissolve the available sodium.

When hydrogen is attached to the more highly electronegative oxygen atom in a water molecule?
Mandarinka [93]

Here is the full question with choices: When hydrogen is attached to the more highly electronegative oxygen atom in a water molecule, __________.?

A. the hydrogen atom becomes partially positive

B. the electronegative atom becomes strongly positive

C. the hydrogen atom becomes partially negative

D. the oxygen atom becomes partially negative

The answers are A and D. The oxygen holds onto the electrons more of the time so is slightly negative, making H slightly positive and thus making a polar covalent bond.
