Answer:
Explanation:
1. Find the empirical formula of a compound that has 36% of Calcium (Ca), 64% of Chlorine (Cl).
2. Find molar mass of each component: Ca=40.078, Cl=35.453
3 Convert to moles: Ca=0.8982484155896, Cl=1.8052068936338
4 Find smallest mole value: 0.8982484155896
5 Divide all components by the smallest value: Ca=1, Cl=2.0096967189738
6 Round to closest whole numbers: Ca=1, Cl=2
7 Combine to get the empirical formula: CaCl2
Answer:
The answer is C. AB is an intermediate; therefore the rate law is determined from the reactants in the previous step.
I just took the test and C. was correct. Please mark me as brainliest!
Answer:
Independent Variable: Grade Level
Dependent Variable: Growth in height
Hypothesis: Students in [Insert the grade level you believe will grow the quickest here] will experience the quickest growth in height.
Explanation:
Independent variables are the factors in which you manipulate to gain your results, in this case you would be changing the grade level you would observe to see the height.
Dependent variables are the factors that respond to changes in the independent variables. You don't control these events, you simply observe them. In this case, you merely observe the growth in height in accordance to the different grade levels you observe.
For the hypothesis, you would create your own hypothesis based on a guess you have. You create a hypothesis not based on the data, but on what you believe will be correct before doing the experiment. It doesn't have to be the correct answer, but just your thoughts.
It is part of oceans, air, rocks, soil and all living things. Carbon doesn't stay in one place. It is always on the move! In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide.
Hope this helps.
