Salt: NaCl
Hydrogen gas: H2
Answer:
Me and my friends were going to do a science experiment. Jonny’s job was to make the HYPOTHESIS. He said the “ If we mix baking soda and vinegar together, the TEMPERATURE will go down.”
So then Molly mixed the baking soda and vinegar together and checked the TEMPERATURE. We all OBSERVED as the thermometer’s TEMPERATURE went down. “ your THEORY/ HYPOTHESIS was correct!” Exclaimed Molly.
Then the whole science GROUP let out with a cheer! And wrote the information down on their EXPERIMENTAL info chart. They took a microscope and looked at the mixture because they wanted to the the little PARTICLES in the mixture. Lily CONTROLED the microscope she zoomed in and out to see the particles.

Answer:
Organisms compete for the resources they need to which are survive- air, water, food, and space.
Answer:
Change in enthalpy for the reaction is -536 kJ
Explanation:
- Overall chemical reaction can be represented a summation of two given elementary steps with slight modification.
- Take reaction (1a) and divide stoichiometric coefficients by 2
- Take reverse reaction (2a) and divide stoichiometric coefficient by 2
- Then add these two modified elementary steps to get overall chemical reaction
is an additive property. hence value of
will be changed in accordance with modification

The energy source from a reservoir would provide affordable, abundant electricity for a factory is a hydroelectric power plant; option D.
<h3>What is energy?</h3>
Energy is the ability to do work.
Energy generating plants may either use wind, water or solar energy to produce electrical energy.
The most abundant source of energy from a reservoir is hydroelectric power plant.
Therefore, the energy source from a reservoir would provide affordable, abundant electricity for a factory is a hydroelectric power plant.
In conclusion, hydroelectric power plants are reservoirs of abundant energy supply.
