Answer:

2,354,084.7 J

Explanation:

-We apply the Specific Heat Capacity formula to solve for the heat loss:

Q=mc\bigtriangleup T

where

m is the mass of the substance

Q is the heat loss/gain

c is the substance's specific heat

T is the change in temperature

\Substitute given values in the equation to solve for Q:

Q=mc\bigtriangleup T\\\\\bigtriangleup T=933.15\ K-298.15\ K=635 \ K\\\\\therefore Q=4110\ g \times 0.902\ J/g\textdegree C\times 635 \ K\\\\=2,354,084.7 \ J

Hence, the amount of heat lost is 2,354,084.7 J

What is the correct name of this isotope? *<br><br> oxygen - 16<br> oxygen - 8<br> oxygen - 24
artcher [175]

The correct name of this isotope : Oxygen - 16

<h3>Further explanation</h3>

Given

Isotope : ₈¹⁶O

Required

The correct name

Solution

The elements in nature have several types of isotopes  

Isotopes are elements that have the same Atomic Number (Proton)  

Atomic mass is the average atomic mass of all its isotopes  

In the following element notation,

\large {{{A} \atop {Z}} \right X}

X = symbol of elemental atom

A = mass number

Z = atomic number

The isotope name is usually followed by its mass number, so the symbol above can be expressed as oxygen - 16
