Answer:
Some human activities that contribute to climate change would be fracking, driving vehicles, deforestation, and developing cities. Fracking releases methane and other greenhouses gases into the atmosphere. Driving vehicles, like cars or trains, also releases carbon dioxide into the atmosphere. Deforestation decreases the amount of oxygen being produced. Developing cities also contributes because it consumes almost 80% of the world's energy, as well as producing 60% of the greenhouse gases.

Ni2+, Ag+, Sr2+, and Mn2+, & with the Addition of HCl --> AgCl ppts
<span>Ni2+, Sr2+, and Mn2+, & with the Addition of H2SO4 --> SrSO4 ppts </span>
<span>Ni2+, and Mn2+, & with the Addition of NaOH --> both Mn(OH)2 & Ni(OH)2 would have ppt'd </span>
<span>but since no ppt,... </span>
<span>there was no Ni+2 or Mn+2 </span>
<span>your answers are </span>
<span>Ag+ & Sr+2 were present </span>
<span>& </span>
<span>Ni+2 & Mn+2 were not present</span>
It it important because it makes people wonder how things work and are made which makes it so they want to move forward with experiments <span />
