Answer:
you can tell diorite is an intrusive igneous rock because it has a coarse-grained texture
Answer:
Beryllium i believe
Explanation:
The answer is Beryllium because it has 4 protons and has 2 electrons.
Answer:
a) % E = 0.501 % error between the measured value and the true value
b) % E = 3.125 % error between the measured value and the true value
Explanation:
- % E = ( ║true value - measured value ║ ) / ( true value ) ) * 100
a) % E = ( ( 0.802 - 0.798 ) / 0.798 ) * 100
⇒ % E = 0.501 %
b) % E = ( ( 0.864 - 0.837 ) / 0.864 ) * 100
⇒ % E = 3.125 %
Answer:
6. 25.8 mL.
7. 16.4 mL.
8. 24.0 mL.
Explanation:
6. Determination of the volume of HCl.
Mass = 30 g
Density = 1.164 g/mL
Volume =..?
Density = mass /volume
1.164 = 30 / volume
Cross multiply
1.164 × volume = 30
Divide both side by 1.164
Volume = 30 / 1.164
Volume = 25.8 mL
7. Determination of the volume of H2SO4.
Mass = 30 g
Density = 1.834 g/mL
Volume =..?
Density = mass /volume
1.834 = 30 / volume
Cross multiply
1.834 × volume = 30
Divide both side by 1.834
Volume = 30 / 1.834
Volume = 16.4 mL
8. Determination of the volume of HNO3.
Mass = 30 g
Density = 1.251 g/mL
Volume =..?
Density = mass /volume
1.251 = 30 / volume
Cross multiply
1.251 × volume = 30
Divide both side by 1.251
Volume = 30 / 1.251
Volume = 24.0 mL
Answer:
They both have the same density.
Explanation:
Density = mass/volume
10g ÷ 4 = 2.5
13g ÷ 5.2 = 2.5
