Answer:
a. Bronze
b. Copper
Explanation:
a. The alloy formed <u>from the mixture of molten tin and molten copper, with copper having the over triple of the quantity of tin</u>, is bronze. Although, these two metals are often not the only metals present in bronze.
b. The solvent in this mixture is molten copper. This is because, <u>it has the larger percentage of the constituents</u> and hence can easily allow other constituents to be dissolved in it.
The given molarity of sodium hydroxide solution = 2.0 M
The required concentration of sodium hydroxide is 65 mL of 0.6 M NaOH
Converting 65 mL to L:
Calculating the moles of NaOH in the final solution:
Finding out the volume of 2.0 M solution taken to prepare the final solution:
Therefore, 19.5 mL of 2.0 M NaOH solution and make it up to 65 mL to prepare 0.6 M NaOH solution.
Answer:
20 m/s^2
Explanation:
given,
final velocity (v) = 6000m/s
initial velocity (u) = 0m/s
time taken (t) = 5 minutes
= 5×60second
= 300second
acceleration(a) = ?
we know that,
a = (v-u)/t
= (6000-0)/300
= 20 m/s^2
Answer:
You'll have to record the observations in appropriate ways and organize them The way you collect your data should relate to how you're planning to analyze and use it These might for instance include entering numerical observations into a Qualitative data are collected as descriptions anecdotes opinions quote
