Answer:
1 = strontium
2 = technetium
3 = silver
Explanation:
Strontium is present in 2 group of periodic table. It is alkaline earth metal. It is most reactive element and can not found free in nature. it is insoluble in water but react with water and form strontium hydroxide and hydrogen gas is also produced. It is radioactive element.
It is similar to the calcium and can incorporated into bones. The food rich with strontium is used to avoid the osteoporosis. It is found in leafy vegetables, grains, sea foods etc.
In given series strontium is highest in reactivity then technetium, while the technetium is more reactive than silver. The silver is less reactive as compared to both given elements.
Warmer objects have faster particles and higher temperatures. If two objects have the same mass, the object with the higher temperature has greater thermal energy. Temperature is measured with a thermometer.
Answer:
The answer to your question is a balanced equation
Explanation:
Chemical formulas are extremely useful in chemistry and these formulas follow the law of proportions but not the law of conservation of matter.
Coefficients indicate that an equation is balanced if these numbers are in proportion but it is not the answer.
Balanced equation is a feature of the law of conservation of matter.
Subscripts are necessary for chemical reactions but they are not a feature of the law of conservation of matter.
