Soil, rocks, rain, and temperature.
Answer:
0.28M
Explanation:
From the question given, we obtained the following information:
C1 = 1.1 M
V1 = 125mL
V2 = 500mL
C2 =?
Using the dilution formula C1V1 = C2V2, we can easily find the molarity of the diluted solution as follows:
C1V1 = C2V2
1.1 x 125 = C2 x 500
Divide both side by 500
C2 = (1.1 x 125)/500 =
C2 = 0.28M
Answer:
Volume of the sulfuric acid (25cm³), same mass of each metal (1g)
Explanation:
In an experiment, the CONTROL VARIABLE also known as constant is the variable that is kept unchanged for all groups in an experiment. This is done in order not to influence the outcome of the experiment.
In this case, students are trying to investigate the reactivity of four different metals. They added 1 g of each metal to 25cm³ of sulfuric acid and recorded the temperature change. Based on the explanation of control variable above, the VOLUME OF SULFURIC ACID (25cm³) and the MASS OF EACH METAL (1g) are the CONTROL VARIABLES because they are the same or unchanged in this experiment.

1.) No we are not alone in the universe.
2.) We are the only species on this planet with the foresight capable of deliberately plotting a path toward a desirable long-term future. Plan it for the apes; because they can’t.
3.) the state of being awake and aware of one's surroundings.
4.) Dreams are basically stories and images our mind creates while we sleep. ... Dreams can occur anytime during sleep. But most vivid dreams occur during deep, REM (rapid eye movement) sleep, when the brain is most active.
5.) Definition of Solar Energy. When the sun's energy reaches the earth in the form of sunlight, it can be converted into other forms of energy. The sun is a huge ball of gas, mostly hydrogen with a little helium.
