7. If the atomic number of an element is 6 and its mass number is 14, how many

Jet001 [13]

Answer:

14-6

8

so 8 is the answer because atomic number is number of protons and atomic mass is sum of protons and neutrons so to find the number of neutrons we will subtract proton number with the atomic mass.

Thanks

The H⁺ concentration in an aqueous solution at 25 °C is 9.1 × 10⁻⁴. What is [OH⁻]?

Vinvika [58]

Steps:-

First we calculate pH then pOH then [OH-]

$\\ \tt\rightarrowtail pH=-log[H^+]$

$\\ \tt\rightarrowtail pH=-log[9.1\times 10^{-4}]$

$\\ \tt\rightarrowtail pH=-log9.1-log10^{-4})$

$\\ \tt\rightarrowtail pH=0.95+4$

$\\ \tt\rightarrowtail pH=4.95$

Now

$\\ \tt\rightarrowtail pH+pOH=14$

$\\ \tt\rightarrowtail pOH=14-4.95$

$\\ \tt\rightarrowtail pOH=9.05$

So

$\\ \tt\rightarrowtail -log[OH^-]=9.05$

$\\ \tt\rightarrowtail log[OH^-]=-9.05$

$\\ \tt\rightarrowtail OH^-=10^{-9.05}$

$\\ \tt\rightarrowtail OH^-=8.91\times 10^{-4}$

What is the approximate temperature of 1.4 moles of a gas with a pressure of 3.25 atmospheres in a 4.738-liter container

attashe74 [19]

Answer:

134K

Explanation:

Using the ideal gas law equation;

PV = nRT

Where;

P = pressure (atm)

V = volume (Litres)

n = number of moles (mol)

R = gas constant (0.0821 Latm/Kmol)

T = temperature (K)

Based on the information provided, n = 1.4moles, P = 3.25atm, V = 4.738L, T = ?

3.25 × 4.738 = 1.4 × 0.0821 × T

15.3985 = 0.11494T

T = 15.3985/0.11494

T = 133.969

Approximately;

T = 134K
