Answer:
Covalent
Explanation:
Sulfur and Chlorine are non metals so if they combine, they become covalent.
Answer:
Is this chemistry or ELA!
Answer: The answer is B.Sonar and C.Radar
Explanation:
They are both just like an echo which is the main things that uses reflected sound waves. They are basically like synonyms for echo.
Coefficients, you can’t change the subscripts but you can balance the equation by adding coefficients to both sides
Ok, after doing an immense amount of research I came up with the most logical answer.
A. Is indicated by a negative enthrall sign.
Reasoning: an endothermic reaction is ice melting and the energy being more than its surroundings. Not specified to ice but as an example, ice is endothermic. That puts d and b out of the running leaving you left with a and c.
When I searched up enthalpy, it said “When a substance changes at constant pressure, enthalpy tells how much heat and work was added or removed from the substance.” Which is similar to c, right? Yeah, meaning both a and c are similar in that aspect.
The reason I decided to go with a is because heat is NOT released into the surrounding, exothermic reactions release energy and heat into the surrounding.
