The symbol for the compound dinitrogen trisulfide is N2S3. It is derived from the number of nitrogen and sulfur atoms present in the compound.
The chemical compound dinitrogen trisulfide is composed of two elements: nitrogen (N) and sulfur (S). When we name the compound according to IUPAC nomenclature rules, we consider the number of each type of atom present. Dinitrogen means there are two nitrogen atoms, represented by the subscript 2, and trisulfide implies that there are three sulfur atoms, signified by the subscript 3. Hence, the symbol or chemical formula for dinitrogen trisulfide is N2S3.

B. calcium
C. rhodium
D. chlorine
Answer:
Calcium
Explanation:
Calcium is needed in our body to make bones (skeletal system) and teeth strong. Apart from making bones and teeth strong, it is required in other body functions such as:
Enabling blood to clot
Helping in muscle contraction
Helping heart muscle in maintaining normal heart beat
About 99% of calcium present in the body is stored in bones. Calcium is stored in bones in the form of calcium phosphate.
Bones continuously replace old calcium with new one. Calcium is not produced in our body. It comes from daily diet, therefore, it essential to take calcium rich diet.
b. all chemical reactions at the same rate.
c. all chemical reactions at a fast rate.
d. all chemical reactions occur at different rates.
Hi there!
Analyzing This Question Correctly We Can conclude thatthe Most accurate and correct answer is D.
We Can conclude to this By using The collision theory.The Collision Theory states that in order for a reaction to proceed, the reactant particles must collide. The more successful collisions there are per unit of time, the faster the reaction will be.
Factors which can affect the rate of a reaction include:
⚛ concentration
⚛ temperature
⚛ particle size
⚛ catalysts
⚛ stirring rate
⚛ light intensity
For Example, By adding less Baking soda to Vinegar the less Co2(Carbon Dioxide) Will Be created.
By Adding More Baking Soda to vinegar, more Co2 Will Be created.
