Answer:
Less
Explanation:
The hydronium from the HCl is used to neutralize the bicarbonate in the baking soda. The hydronium is the acid and the bicarbonate ion is the base while the sodium and chloride ions are pH-neutral. Since theres a 1:1 mole ratio of hydronium to HCl and bicarbonate to sodium bicarbonate, it would require less HCl to neutralize a less concentration baking soda solution.
Answer:
is agriculture that makes healthy food,healthy soil,healthy plants and healthy environments a priority,along with crop productivity
Answer: exothermic
EXPLANATION: any process in which heat energy is released is called an exothermic process. For example burning of wood produces heat, so combustion of wood is an exothermic process.
When chemicals were not mixed they were at room temperature and when we mix them exothermic reaction took place and heat was released which raised the temperature of mixture.
Following are important constant that used in present calculations
Heat of fusion of H2O = 334 J/g
<span>Heat of vaporization of H2O = 2257 J/g </span>
<span>Heat capacity of H2O = 4.18 J/gK
</span>
Now, energy required for melting of ICE = <span> 334 X 5.25 = 1753.5 J .......(1)
Energy required for raising </span><span>the temperature water from 0 oC to 100 oC = 4.18 X 5.25 X 100 = 2195.18 J .............. (2)
</span>Lastly, energy required for boiling water = <span> 2257X 5.25 = 11849.25 J ......(3)
</span><span>
Thus, total heat energy required for entire process = (1) + (2) + (3)
= 1753.5 + 2195.18 + 11849.25
= </span><span>15797.93 J
</span><span> = 15.8 kJ
</span><span>Thus, 15797.93 J of energy is needed to boil 5.25 grams of ice.</span>
C. Fewer habitats for wild animals to live in
Explanation:
Biodiversity does not directly impact humans in that there are fewer habitats for wild animals to live in. This is a direct impact on animals and not humans.
Biodiversity is the variation of life forms in an area. It is measured by the ability of the ecosystem to sustain different life forms and keep their interaction with the environment.
It helps to maintain and sustain life.
To humans, reducing biodiversity;
- reduces the potential of medicine derived from other organisms. When their habitat is lost, we lose them.
- fewer ecosystems to appreciate for beauty and recreation. It leads to loss of the ecosystem.
- fewer wild food species for humans to eat.
Loss of habitat directly affects wild animals and not man.
