Radio waves.
From lowest to highest it is radio wave, microwave, infrared, visible light, ultraviolet, x ray, and then gamma.
Answer:
Newton's first law is a object at rest stays at rest unless acted by and outside force
Explanation:
say there is a ball sitting still it is at rest well say a kid comes over and kicks the ball the kid is the outside force that puts the ball in motion so the ball goes from sitting still to moving by the outside force also known as the kid
Answer:
this subject takes time. i would study nonstop. past year i was 1 of 10 that passed our chemistry class with 200 people in it. it just takes time
Answer:this Covalent bond
Explanation:Covalent bond involves a pair of electrons being shared between atoms.
Hope this helps!
Answer:
a. absorbs energy as heat and has positive enthalpy of solution.
Explanation:
A reaction can either be exothermic or endothermic. An endothermic reaction, as the dissolution described in the question, is that which absorbs heat energy from the surroundings in order to start the reaction.
Because an endothermic reaction makes heat lost from the surroundings, the enthalpy (∆H) of the solution will be positive (+). ∆H is got by finding the difference between the enthalpy of the reactants and products and since the enthalpy of a product in endothermic reaction is more, the enthalpy change (∆T) will be positive.
