Why a neutral atom has the same number of protons and electrons

Chemistry
1 answer:
Alex777 [14]4 years ago
5 0

Explanation:

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.

A piece of gold wire has a diameter of 0.175 cm. How much will precisely 1.00 x 10^5 of the wire weight?
Mamont248 [21]

Given data:

Diameter of the gold wire (d) = 0.175 cm

Length of the gold wire (l) = 1.00 * 10^{5} cm

Volume of the given gold wire = volume occupied by a cylindrical object\

                                       = π * r^{2}*l

here r = radius of the cross section

where : r = d/2

Hence the volume V = π * (d/2)^{2}*l

            = 3.142 * (0.175/2)^{2} * 1.00*10^{5} = 2.41 * 10^{3} cm^{3}

Density of gold = 19.3 g/cm3

Weight of the gold wire = Density * volume

= 19.3 g/cm^{3} * 2.41*10^{3} cm^{3}

= 4.65 * 10^{3} g = 4.65 kg

A 52-gram sample of water that has an initial temperature of 10.0 °C absorbs 4,130 joules. If the specific heat of water is 4.18
FinnZ [79.3K]

Answer:

The final temperature of the water is 28.98 degree Celsius.

Explanation:

It is given that,

Mass of sample of water, m = 52 grams

Initial temperature, T_i=10^{\circ}C

Heat absorbed, Q=4,130\ J

The specific heat of water is 4.184\ J/(g^{\circ} C)

We need to find the final temperature of the water. The heat absorbed is given by the formula as follows :

Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\T_f=\dfrac{Q}{mc}+T_i\\\\T_f=\dfrac{4130}{52\times 4.184 }+10\\\\T_f=28.98^{\circ} C

So, the final temperature of the water is 28.98 degree Celsius.
