Answer:
the answer is water
Answer: water
Explain: Gradpoint
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

★ C = 6, H = 6, O = 1
★ the number of molecules.
Answer:
The subscripts in a chemical formula represent two things:
Explanation:
The subscripts in a chemical formula represent two things:
1. The number of atoms: The subscripts indicate the number of atoms of each element present in a compound. For example, in the chemical formula H2O, the subscript "2" indicates that there are two hydrogen atoms in each water molecule.
2. The number of molecules: The subscripts can also represent the number of molecules in a compound. However, it's important to note that this is not always the case. In most cases, the subscripts in a chemical formula specifically indicate the number of atoms rather than the number of molecules.
To clarify the examples given:
- The statement "★ the number of atoms" is correct. Subscripts in a chemical formula do represent the number of atoms.
- The statements "★ C = 1, H = 6, O = 5" and "★ C = 6, H = 6, O = 1" are not relevant to the question as they do not pertain to the role of subscripts in a chemical formula.
Answer:
= 25 g
Explanation:
Using the formula;
A = A₀ (1/2)^(t/h)
where A is the final amount,
A₀ is the initial amount of the substance,
t is the time and
h is the half-life of the substance,
In this case; the half life of U-238 h is equal to 4.47 billion years.
A = A₀ (1/2)^(t/h)
A = 50 (1/2)^(4.5 / 4.47)
= 24.88
= 25 g
Answer:
C) 25 grams
Explanation:
25 grams would remain after one half-life (4.5 billion years). Find the point where percent remaining is 50% and that will tell you it is one half-life.
