Construct <br> an isotope has 17 protons 20 neutrons and 18 electrons

ASHA 777 [7]

Add proton + neutrons = Mass 37

Proton is same as your atomic mass= 17

If you go on the periodic table look up 17 and it will give u the letter.

A forward reaction in which adding heat decreases product formation is _________, while a forward reaction in which adding heat

ELEN [110]

I believe the correct answer from the choices listed above is option A. <span>A forward reaction in which adding heat decreases product formation is exothermic, while a forward reaction in which adding heat increases product formation is endothermic. Exothermic would mean that heat is being released by the process while the opposite is called endothermic in which it absorbs heat.</span>

2) Which liberates the most energy?

evablogger [386]

Answer: $F(g)+e^-\rightarrow F^-(g)$

Explanation:

Electron gain enthalpy is defined as energy released on addition of electron to an isolated gaseous atom.

The amount of energy released will be maximum when the tendency to attract electrons is maximum. As flourine has atomic number of 9 and has electronic configuration of 2,7. It can readily gain 1 electron to attain stable noble gas configuration and hence liberates maximum energy.

$F(g)+e^-\rightarrow F^-(g)$

A 35.66g sample of copper is heated using 600j of energy. if the original temperature of the copper is 85C what is its final tem

ira [324]

This problem is providing the mass, energy, initial temperature and specific heat of a sample of copper that is required to calculate the final temperature.

Thus, we recall the general heat equation:

$Q=mC(T_f-T_i)\\$
