GIVING 20 POINTS!! Apply Concepts Two chemists each plan an investigation in which they will combine hydrogen gas with chlorine gas to observe the chemical reactivity. The plans differ in that one will use 25 milligrams each of hydrogen and chlorine, and the other will use 1000 times this amount, i.e., 25 grams each of hydrogen and chlorine. Can the investigations reach similar conclusions about the reactivity of hydrogen with chlorine? Explain.
Answers
Answer:
Yes, the investigations will reach similar conclusions about the reactivity of H2 and Cl2
Explanation:
1. The law of multiple proportions says that when elements form compounds, the proportions of the elements in those chemical compounds can be expressed in small whole number ratios. This means that regardless of whether 1000 times more of the products are used, the reactivity of the products is established by the chemical reaction
2. The law of multiple proportions is an extension of the law of definite composition, which states that compounds will consist of defined ratios of elements.
3. A reaction with more reactants will need more care because more products are produced, which can be toxic
4. H2 and Cl2 reactivity does not depend on the quantities but the chemical properties of each compound

The density of water in g/ml up to 4 significant figures at 6°C is 0.9999432 g/cm³.
What are significant figures?Significant figures are used for establishment of a number which is presented in the form of digits. These digits give a meaningful representation to the numbers.
The significant figures are the significant digits which convey the meaning according to the accuracy. These provide precision to the numbers and hence are called as significant numbers.There are rules for counting significant figures which are as follows:
1)All non-zero digits are significant .
2)All zeroes which occur between non-zero digits are significant.
3)All zeroes to the left and right of a non-zero digit are not significant.
4) All zeroes on right of decimal are significant if a non-zero number follows them.
5)All zeroes on right side of non-zero digit are significant

give any two reasons that hydrogen is kept in group 1 in Modern Periodic Table
Answers
Answer:
Hydrogen is usually classified as a group 1 element since it has one valence electron, just like group 1 metals.
Explanation:
place the letters on the spectrum below from least scientific two more scientific A. All living things are composed of one or more cells. We know this because every living thing examined to date has
been found to be composed of one or more cells.
B. If you break a mirror, you will have seven years of bad luck.
C. The Earth is flat. Anybody can see that!
D. Taking Vitamin C prevents the common cold. Linus Pauling, the Nobel laureate who discovered the structure of
Vitamin C, says it does.
E. Humans have a soul. I believe this because it says so in the Bible. The soul is what separates us from animals.

Answers
Answer: B, C, E, D, A, F
Explanation: It is a little difficult to assign a regid order to these statements. Much depends on one's definition of "more scientific." My thoughts:
B: Only in the movies
C: Flat Earthers still exist, but no one has ever fallen off the edge, that I'm aware of
E: I've had a few pets with souls. My cat has it in for me.
D: I met Linus Pauling twice - he was too enthusiastic with his vitamin C and did not critically evaluate the evidence, but he was far more correct than the Flat-Earthers.
A: Lots of good evidence, although it can also depend on the definition of "living," Is a virus "living?"
F: Yep, I've done it myself. Heavier object have more inertia - they are the couch potatoes of physics. They will take their own time to get moving.
