Answer:
Explanation:
Net force F = 1800 N
acceleration a = 1.5 m /s²
mass = m
mass = force / acceleration
= 1800 / 1.5
m = 1200 kg
Answer:
0.1 mol
Explanation:
Step 1: Given data
- Volume of the solution of sodium hydroxide (V): 200 cm³
- Molar concentration of sodium hydroxide (C): 0.5 mol/dm³
Step 2: Convert "V" to dm³
We will use the conversion factor 1 dm³ = 1000 cm³.
200 cm³ × 1 dm³/1000 cm³ = 0.200 dm³
Step 3: Calculate the moles (n) of NaOH
The molarity of the NaOH solution is equal to the moles of NaOH divided by the volume of solution.
C = n/V
n = C × V
n = 0.5 mol/dm³ × 0.200 dm³ = 0.1 mol
The answer is proteins.
Albumin is a protein produced in the liver. It belongs to the great family of globular proteins. Since it is the protein, the only macromolecule present in the albumin can be only protein.
Group 18 is the only group in periodic table in which all the elements are nonmetals. This group contains F, Cl, Br, I and At and also the other name of this group is halogen which means salt producer.
