Answer:
d = 0.5×10¹g/cm³
Explanation:
Given data:
Volume of material = 2 m³
Mass of material = 1×10⁴ Kg
Density of material = ?
Density:
Density is equal to the mass of substance divided by its volume.
Formula
d = m/v
Solution:
Volume of material = 2 m³
1 m³ = 1000000 cm³
2 ×10⁶cm³
Mass of material = 1×10⁴ Kg
1 Kg = 1000 g
1×10⁷ g
by putting values into density formula
d = 1×10⁷ g/2 ×10⁶cm³
d = 0.5×10⁷⁻⁶ g/cm³
d = 0.5×10¹g/cm³
Hey there!
2Na + Cl₂ → 2NaCl
This is a balanced chemical equation.
There are 2 atoms of sodium (Na) on the left, and 2 atoms of sodium (Na) on the right.
There are 2 atoms of chlorine (Cl) on the left, and 2 atoms of chlorine (Cl) on the right.
This means the equation is balanced since there are the same amount of each element on both sides.
Hope this helps!
When a physical change occurs, the arrangement of particles within the substance may change, but the atoms in the molecules remain bonded together.
