The hydronium ion concentration in an aqueous solution is [H+] = 5.3 x10-4 M. What is the hydroxide ion concentration? Is this s

VladimirAG [237]

Answer:a

Explanation:

Given

$[H^+]=5.3\times 10^{-4}\ M$

and $pH+pOH=14$

Also $pH=-\log [H^+]$

therefore $pH=-\log (5.3\times 10^{-3})$

$pH=-(-4-\log (5.3))$

$pH=3.275$

Thus $pOH=14-3.275$

$pOH=10.275$

and $pOH=-\log [OH^{-}]$

$[OH]^{-1}=10^{-10.25}$

$[OH]^{-1}=1.88\times 10^{-11}\ M$

As the pH is less than 7 therefore solution is acidic

Using the rules for significant figures, what do you get when you subtract 15.54 from 508.9538? A. 493 B. 493.4 C. 493.41 D. 493

IceJOKER [234]

You get 493.41 when you subtract 15.54 from 508.953 using the rules for significant figures.

For addition and subtraction, look at the decimal portion (i.e., to the right of the decimal point) of the numbers ONLY. Here is what to do:

1) Count the number of significant figures in the decimal portion of each number in the problem. (The digits to the left of the decimal place are not used to determine the number of decimal places in the final answer.)

2) Add or subtract in the normal fashion.

3) Round the answer to the LEAST number of places in the decimal portion of any number in the problem.

The correct answer between all the choices given is the third choice or letter C. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

A point P is placed exactly between two charges, Q1 and Q2. If the electric field experienced by point P due to charge Q1 is 1.5

iren2701 [21]

<em>Answer: D</em>

<em>Given data:</em>

The electric field due to charge q₁ is (E₁) = 1.5 × 10⁵ N/C

The electric field due to charge q₂ is (E₂) = 7.2 × 10⁵ N/C

Determine the net electric field at point P (Enet) = ?

electric field measured in Newtons/coulomb

The net electric field (Enet) is vector sum of E₁ and E₂ caused by the charge q₁ and q₂ respectively
