If your choices are the following: A.Neutrons released during a fusion reaction cause other nuclei to fuse.
B. Neutrons released during a fission reaction cause other nuclei to split.
C. Helium nuclei released during a fission reaction cause other nuclei to split.
D. Helium nuclei released during a fusion reaction cause other nuclei to fuse.
Then the answer is B. In fission, the nuclei is splitted and releases neutrons causing another chemical to form.
Answer:
[OH⁻] = 0.002 M
Explanation:
<u>The definition of pOH</u> is similar to the definition of pH:
This means that with a <u>given pOH value</u>, the calculation of [OH⁻] is a matter of algebra:
To remove the logarithm we increase 10 by the power of the pOH:
- =[OH⁻]
<h3>
Answer:</h3>
1.265 g/mL
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of a rock as 43 g
- Volume of the rock as 34 mL
- Altitude of the rock as 4390 ft
We are required to calculate the density of the rock.
Density is the mass of an object per unit volume.
It is calculated by;
Density = Mass / volume
Therefore;
Density = 43 g ÷ 34 mL
= 1.265 g/mL
Thus, the density of the rock is 1.265 g/mL
Answer:
D
Explanation:
It is higher in the air, so it will fall faster then the other apples.
