Answer : The correct option is, (D) electrically neutral

Explanation :

There are three subatomic particles which are protons, neutrons and electrons. Protons and neutrons are present in the center of the nucleus and electrons are located around the nucleus. The protons are positively charged, electrons are negatively charged and neutrons are neutral, they have no charge.

In an electrically neutral atom, the number of protons are equal to the number of electrons.

In a positively charged and negatively ions, the number of protons are not equal to the number of electrons.

In a radioactive stable atom, the number of protons are not equal to the number of electrons.

Hence, an equal number of protons and electrons in an atom typically results in an atom that is electrically neutral.

A 19-g piece of metal absorbs 186.75 joules of heat energy, and its temperature changes from 35°C to 175°C. Calculate the specif
slavikrds [6]

Answer:

0.0702J/g°C the specific heat capacity of the metal.

Explanation:m

Q=m\times c\times \Delta T=m\times c\times (T_{2}-T_{1})

where,

Q = heat absorbed by metal = 186.75 J

m_1 = Mass of metal= 19 g

T_1 = Initial  temperature of metal = 35^oC

T_2 =Final  temperature of metal = 175^oC

c = specific heat of metal= ?

186.75 J=19 g\times c\times (175^oC-35^oC)

c=\frac{186.75 J}{19 g\times (175^oC-35^oC)}

c=0.0702J/g^oC

0.0702J/g°C the specific heat capacity of the metal.

How to balance Na + FeBr3 →
Lubov Fominskaja [6]

Hey there!

Na + FeBr₂ → NaBr + Fe

Firstly, balance Br.

Two on the left, one on the right. Add a coefficient of 2 in front of NaBr.

Na + FeBr₂ → 2NaBr + Fe  

Next, balance Na.

One on the left, two on the right. Add a coefficient of 2 in front of Na.

2Na + FeBr₂ → 2NaBr + Fe

Lastly, balance Fe.

One on the left, one on the right. Already balanced.

Our final balanced equation:

2Na + FeBr₂ → 2NaBr + Fe

Hope this helps!

The reaction that occurred when the antacid mixed with the HCl resulted in an additional product (besides a salt and water). Did
QveST [7]

Answer:

Explanation:

If an antacid has sodium hydrogen carbonate/Calcium carbonate, it reacts with HCl as shown

NaHCO₃+ HCl → NaCl + CO₂+ H₂O

Antacid acid salt gas water

CaCO₃+ 2HCl → CaCl₂+ CO₂+ H₂O

Antacid acid salt gas water

The formation of gas CO₂ is shown by brisk effervescence when the antacid (sodium hydrogen carbonate/calcium carbonate) reacts with HCl (acid). So CO₂ is the additional product formed and its formation is supported by observation of brisk effervescence as HCl is added to the antacid.
