Liquid reactant A: 10 g
Liquid reactant B: 17 g
Beaker+Solid product: 32 g
What is the mass of the beaker?
a. 5 g
b. 10 g
c. 15 g
d. 17 g
e. 32 g
This might be right. Im not quite sure. This is what my 5th grade science teacher told me. 'Look at the 2 LR's and add them together. Then look at the total amount which is 32. When you add the 2 LR's you get 17. So subtract 17 from 32 and you get 15. So: C:15 is your answer." (LR's stands for liquid reactants)
10+17=17
Total amount is 32
32-17=15
15 is you mass
Hope this Helps
Its 5g i took the quick check
Answer:
36000 centimeters
Explanation:
If the average speed of a species of tortoise is 0.36 km/h, then it would be 36000 centimeters.
B. Weak
C. Acidic
D. Flammable
If an average cell phone is dropped from a typical cruising altitude of an airplane, neglecting air resistance, it would take about 107 seconds to reach the ground.
The subject this question falls under is physics because it involves the physical principles of gravity and free fall. If we ignore air resistance (a common simplification in basic physics problems), we can solve this problem by employing the equation for the time (t) of a free-falling object:
t = √(2h/g),
where h is the height the object falls from and g is acceleration due to gravity (about 9.8 m/).
Notice that we would need to first convert 37,000 feet to meters (about 11,277.6).
By substituting these values into our formula, we get a value that indicates that a phone falling from the typical cruising altitude of an airplane would take about 107 seconds to hit the ground.
