Answer:
The solidifying/cooling and crystallizing of magma causes igneous rocks to form.
Answer:
8.6g/cm³ (BRASS)
Explanation:
Given the following :
Mass of object = 86g
Volume of object = 10cm³
The density of an object is calculated using the formula :
Density(g/cm³) = mass(g) / volume(cm³)
Inputting our values :
Density = 86g / 10cm³
Density = 8.6g/cm³
According to the table provided, the object which corresponds to having a density of 8.6g/cm³ is BRASS
Following the law of conservation of mass, the mass percent of hydrogen in the resulting compound is 14.4%(wt/wt). This is assuming that all of the carbon reacts with all of the hydrogen. The solution is as follows:
mass % = mass hydrogen*100/total mass = 28.8*100/(28.8+171.2) = 14.4%
Answer:
Theoretical yield = 3.75g
Explanation:
Percent yield is defined as one hundred times the ratio between actual yield and theoretical yield. The expression is:
Percent yield = Actual Yield / Theoretical Yield * 100
In the problem, your actual yield was 3-00g.
Percent yield is 80.0%.
Solving for theoretical yield:
80% = 3.00g / Theoretical yield * 100
Theoretical yield = 3.00g / 80.0% * 100
<h3>Theoretical yield = 3.75g</h3>
Is it multiple choice? If not your answers are metals, and when nonmetals react.
