Answer: C
Explanation: We learnt this in science so it must be true.
sry if it’s not
Answer:
1.5g
Explanation:
According to this question, the amount of copper required to obtain copper sulfide in a 4:1 is 6g. This means that the ratio of copper to sulfur in the compound (copper sulfide) is 4:1.
Hence, to calculate the amount of sulfur required for the reaction to obtain copper sulfide using the above ratio, we say:
1/4 of the amount of copper required (6g)
= 1/4 × 6
= 6/4
= 1.5g of sulfur is required for the reaction to obtain carbon sulfide.
Hello Olivia!!!
<span>Q.) Describe at least two geological events that can occur at a divergent boundary.
</span>
A.)Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.
Hope this can help!!!
A base taste bitter, not sour, so not D, But a base is slippery, so B.
Answer:
[H⁺] = 1.8 ×10⁻⁴ mol/L
Explanation:
Given data:
pH of HNO₃ = 3.75
[H⁺] = ?
Solution:
Formula:
pH = -log [H⁺]
Now we will put the values.
3.75 = -log [H⁺]
[H⁺] = 10⁻³°⁷⁵
[H⁺] = 1.8 ×10⁻⁴ mol/L
