Answer: yes
Explanation:
even in combined state, radioactive elements continue to emit radiation spontaneously. For instance RaCl2 is still radioactive because of the radium content of the compound. This is applied positively in radionuclides used to study chemical reactions or uptake of certain elements in then body.
Your going to want to round 8.01 to 8.01 and change 3.127 rounded too 3.1
then u want to take 8.0 and 3.1 and times it and u will get 24.8 or 25
Answer is (D) - It is exothermic and will have a negative enthalpy.
If the reactants are at a higher potential energy compared to the products, it means reactants have more energy than the products. That energy is released to the environment as heat. Due to the releasing of heat to the surrounding, the reaction is exothermic. Since the reaction is exothermic; the enthalpy of the reaction will be negative value.
Answer:
<h3> 4000</h3>
More than 4,000 naturally occurring minerals—inorganic solids that have a characteristic chemical composition and specific crystal structure—have been found on Earth. They are formed of simple molecules or individual elements arranged in repeating chains, sheets, or three-dimensional arrays.
