Chemistry

Vlada [557]1 year ago
6 0

Answer:

Yes is my final answer

Explanation:

1. Scrap iron is used to displace copper because it is a more reactive, cheaper metal, making it a cost-effective way to produce copper. Scrap or old iron is also easier to obtain, as it is one of the world’s most recycled scrap metals. During a displacement reaction, iron reacts with a copper sulphate solution. This causes the iron ion to displace the copper to form iron sulphate, with solid copper being produced as a result.

Elan Coil [88]

The answer would be:

Oceanic-Oceanic Convergent Plate

This is why:

When two oceanic plates collide, the heavier of the two would subduct or in other words, go under the other plate. When this happens, ocean trenches and volcanic arcs form. The trench forms at the point oceanic plate goes under the other plate. And above the other plate that goes over create volcanic arcs.

The output of a plant is 4335 pounds of ball bearings per week (5days) if each ball weighs .0113 g how many ball bearings does t
AfilCa [17]

The plant makes 3.50 × 10⁷ bearings per day

<em>Pounds of bearings</em> = 1 da × (4355 lb bearings/5 da) = 871.0 lb bearings

<em>Grams of bearings</em> = 871.0 lb bearings × (453.6 g bearings/1 lb bearings)

= 3.951 × 10⁵ g bearings

<em>No. of bearings</em> = 3.951 × 10⁵ g bearings × (1 bearing/0.0113 g bearing)

= 3.50 × 10⁷ bearings
