Answer:
Sulphur (S)
Explanation:
F2 + H2S ¬¬¬> S+2HF
As we have 2 F and 2 H, they combine to form 2HF. We are left with S only
It is because when copper is hammered into a sheet (malleable) or drawn into a wire (ductile), layers of atoms move past one another without disrupting the force between the cations and the negative 'sea' of electrons. it is because of the non directional nature of the metallic bond.
- malleable is a term used to describe material that can be pounded into shapes
- A ductile material is one that can be pulled out, or drawn, into a long wire
- Metal is class of elements characterized by physical properties that include shininess, malleability, ductility, and conductivity.
- Conductors are those Metals who conducts electric current and heat

<span>I would measure the mass of the solid substance. I would prepare a known mass of room temperature water large enough to submerge the solid substance in question. I would place the water in an insulated container. Then I would heat the solid substance to a known temperature. I would measure the temperature of the heated sample and the water. Then I would submerge the sample in the water and allow the sample and the water to reach the same temperature. I would measure this equilibrium temperature.
I would interpret the difference in temperature between the heated sample and the equilibrium temperature as the change in temperature in the sample. Given the known mass, the beginning temperature of the water, and the equilibrium temperature I can determine how much energy was transferred from the heated sample to the water.
Now the mass of the sample, a change in temperature in the solid substance, and the amount of energy transferred to create the temperature is known. This is sufficient to determine the specific heat of the solid substance</span>
Answer:
because it will control the birth of a child which can happen alot being overpopulated in the country or world. It also can mange their life and create a small and happy and healthy family.Also the child can get more love and support from their parents if they have less children and it wont be a taruma for the couple as well. because growing a child can be expensive time costly and really hard.
