Strontium chloride (SrCl) burns with a bright red flame. This characteristic color is due to the presence of strontium ions, which emit red light when heated. The vivid red flame is often used in pyrotechnics and fireworks to create striking visual effects.
Yes, strontium chloride (SrCl₂) is soluble in water and exists as an aqueous solution when dissolved. In this form, it dissociates into strontium ions (Sr²⁺) and chloride ions (Cl⁻). Thus, when SrCl₂ is added to water, it readily forms an aqueous solution.
To find the percentage of strontium in strontium chloride (SrCl₂), first calculate the molar mass of SrCl₂. The molar mass of strontium (Sr) is approximately 87.62 g/mol, and that of chlorine (Cl) is about 35.45 g/mol, so SrCl₂ has a molar mass of 87.62 + (2 × 35.45) = 158.52 g/mol. The percentage of strontium is then (87.62 g/mol / 158.52 g/mol) × 100%, which is approximately 55.2%.
Helium does not burn in a flame test because it is an inert gas and does not react with the flame to produce a characteristic color.
Lilac to Purple-Red
Someone told me it burns blue or purple.
Strontium chloride (SrCl2) is a stable compound. Aluminum fluoride (AlF3) is also stable. Barium sulfide (BaS) is relatively stable but can decompose upon exposure to water or air.

Here You Are : void String_Concate(char *Arr1, char *Arr2) { int r=0; int c = String_Length(Arr1); int x,p; for(int i=0;Arr1[i];i++) { if((Arr1[i]== 32)(Arr1[i]=='\0')) {r= i; break;} } for(x = r,p =0;x<=c + String_Length(Arr2);x++,p++) { *(Arr1 + x) = *(Arr2 + p); } } Have A nice Day
