A positively charged substance is brought near the ion. What will most likely happen and why
d1i1m1o1n [39]

<u>Answer:</u> It repels positive ion and attracts negative ion.

<u>Explanation:</u>

There are 2 types of ions:

1. Cations: These ions are positively charged ions which are formed when a substance looses electrons.

2. Anions: These ions are negatively charged ions which are formed when a substance gains electrons.

It is known that, like charges repel each other and unlike charges attract each other.

As, it is given that the substance is positively charged, so it will attract anion and repel cation.

In a spontaneous fusion reaction, the total mass of the products is ________________________ the mass of the original elements.
Mice21 [21]
I believe the correct term that would fit the statement would be greater than. In a spontaneous fusion reaction, the total mass of the products is greater than the mass of the original elements. This nuclear reaction involves at least two nuclei that fuses to form one nuclei having larger mass than that of the reactant.

How much heat is absorbed by 15.5g of water when it's temperature is increased from 20.0C the specific heat of the water is 4.18
Anuta_ua [19.1K]
Hello!

The exercise doesn't say the final temperature, but we are going to assume that the increase is of 20 °C (The procedure is the same, just change the final temperature) To calculate the heat absorbed by water, we need to use the equation for Heat Transfer, in the following way (assuming that the heat increase is 20°C):

Q=m*C* \Delta T=15,5 g * 4,184 (J/g^\circ C) * 20 ^\circ C=1297,04 J

So, the Heat absorbed by water is 1297,04 J
