The molarity of the lake water is 0.00001 M and the pH of lake water is 5.
The lake water is acidic.
Explanation:
Data given:
molarity of base solution Mbase = 0.1 M
volume of the base solution Vbase = 0.1 ml or 0.0001 litre
volume of lake water Vlake = 1000ml or 1 litre
molarity of the lake water, Mlake = ?
Using the formula for titration:
Mbase X Vbase = Mlake X
Mlake = 
Putting the values in the equation:
Mlake = 
Mlake = 0.00001 M
The pH of the lake water will be calculated by using the following formula:
pH = - 
[
]
pH = - [ 0.00001]
pH = 5
Based on the information provided,
The evidence that this nuclear reaction reaction represent transmutation is it formed different elements

Answer:
the density of the sample - the melting point of the sample
Explanation:
Intrinsic property is the property of matter which exists itself or within subject. In other words, it do not depend on the mass of the sample. An extrinsic property is not inherent or essential to subject which is being characterized. In other words, it depend on the mass of the sample.
For example,
Density, melting point are example of intrinsic property. Whereas, weight, volume are an example of extrinsic property.
Intrinsic properties helps to determine the matter. Thus, density of sample and melting point of sample is the answer.
Answer:Temperature Effects on Density. Density is a physical property of substances that compares the relationship between volume and mass. Density is affected by temperature because as temperature increases so does the kinetic energy of the particles.
Explanation:
Answer:
1. There most not be rotation within the molecule.
2. Two non identical group must be present in the double bonded carbon atom.
Explanation:
This is because cis/ trans isomerism are that exhibit different structural configurations where the atoms are spartially arranged. They are also refered to as geometric isomers. They cannot be interconverted at room temperature because it requires the bonds to be broken and restructured.
Cis shows that the functional groups on present in the same side which trans isomerism show that the functional groups are on opposite sides.
