Answer:
The rock is heavier than water and when put into water it will sink.
Explanation:
Given data:
Mass of rock = 2.7 g
Volume = 1.1 cm³
Type of rock = ?
Solution:
From given data we can calculate the density of rock.
If the density of rock is higher than the density of water it means the rock is heavier than water.
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
d = m/v
d = 2.7 g/ 1.1 cm³
d = 2.5 g/cm³
density of water is 1 g/cm³. The rock is heavier than water and when put into water it will sink.
Answer:
Here's what I get.
Explanation:
Your unbalanced nuclear equation is:
The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
95 = x + 2, so x = 95 - 2 = 93
243 = y + 4, so y = 243 - 4 = 239
Element 93 is neptunium, so the nuclear equation becomes
mol CO₂ = 9.6
mol N₂ = 4.8
mol O₂ = 0.8
mol H₂O = 8

Reaction
4C₃H₅O₉N₃ → 12CO₂ + 6N₂ + O₂ + 10H₂O
mol CO₂
mol N₂
mol O₂
mol H₂O
