Answer:
No its a Chemical change
Explanation:
It is a chemical change because chemicals are the one changing it. It can not physically change itself.
Answer:
d = 4.5 g/cm³
Metal cube is made up off titanium.
Explanation:
Given data:
Edge length of cube = a = 11.4 mm
Mass of metal cube = 6.67 g
Density and identity of metal = ?
Solution:
First of all we will calculate the volume of cube.
V = a³
V = (11.4mm)³
V = 1481.54 mm³
mm³ to cm³:
1481.54 mm³× 1 cm³/ 1000 mm³
1.482 cm³
Density:
d = m/v
d = 6.67 g/ 1.482 cm³
d = 4.5 g/cm³
Metal cube is made up off titanium because density of titanium is 4.5 g/cm³.
Volumetric flask is the most accurate because making solutions often requires very exact volumes. Graduated cylinders are next most accurate because they can be nade thin and thus very precise. Beakers are least accurate because they are thick and extremely accurate measurements are not usually needed in beakers so manufacturers are generally less precise.
Answer:
The ovaries and the testes
Explanation:
<em>The organs responsible for the development of secondary sex characteristics would be the ovaries and the testes.</em>
<u>Both ovary and testes are associated with the sex organs in the body and are responsible for the synthesis of hormones such as androgen and estrogen. While the latter (estrogen) is produced by the ovary, the former (androgen) is produced by the testes.</u>
More specifically, both androgen and estrogen are hormones responsible for the growth of hairs in areas such as the armpit and the pubic regions of the body.
<em>The correct options are </em><em>the ovaries</em><em> and </em><em>the testes</em><em>.</em>
