Answer: 462.00 Joules of heat will be needed to change the temperature of copper from 20° C to 60° C.

Explanation:

Mass of copper,m = 30.0 grams

Specific heat capacity of copper,c = $0.385 J/g ^oC$

$T_1=20^oC,T_2=60^oC$

$\Delta T=T_2-T_1=60^oC-20^oC=40^oC$

$Q=mc\Delta T$

$Q=30.0 grams\times 0.385 J/g ^oC\times 40^oC=462.00 J$

462.00 Joules of heat will be needed to change the temperature of copper from 20° C to 60° C.

Where do most organisms that live in water get oxygen from?Give a word, not a formula.

Anton [14]

Answer:

Surely with water

Ok, but how?

There are many Hydrogen Bond between H2O moleculs and london bonds. When fishes take water with their gill,they are broke london bonds. And they can take their needs, Oxygen. Only this.

Good luck :D

vredina [299]

Answer :

(a) The rate of $NO_2$ formed is, 0.066 M/s

(b) The rate of $O_2$ formed is, 0.033 M/s

Explanation : Given,

$\frac{d[NO]}{dt}$ = 0.066 M/s

The balanced chemical reaction is,

$2NO(g)+O_2(g)\rightarrow 2NO_2(g)$

The rate of disappearance of $NO$ = $-\frac{1}{2}\frac{d[NO]}{dt}$

The rate of disappearance of $O_2$ = $-\frac{d[O_2]}{dt}$

The rate of formation of $NO_2$ = $\frac{1}{2}\frac{d[NO_2]}{dt}$

As we know that,

$\frac{d[NO]}{dt}$ = 0.066 M/s

(a) Now we have to determine the rate of $NO_2$ formed.

$\frac{1}{2}\frac{d[NO_2]}{dt}=\frac{1}{2}\frac{d[NO]}{dt}$

$\frac{d[NO_2]}{dt}=\frac{d[NO]}{dt}=0.066M/s$

The rate of $NO_2$ formed is, 0.066 M/s

(b) Now we have to determine the rate of molecular oxygen reacting.

$-\frac{d[O_2]}{dt}=-\frac{1}{2}\frac{d[NO]}{dt}$

$\frac{d[O_2]}{dt}=\frac{1}{2}\times 0.066M/s=0.033M/s$

The rate of $O_2$ formed is, 0.033 M/s

Which of the following is not conserved in a chemical reaction?

mixer [17]

Mass is not conserved in chemical reactions. Mass is therefore never conserved because a little of it turns into energy in every reaction
