At room temperatures, elements lithium, sodium, rubidium,
barium, vanadium, chromium and iron have structures that can be described as a
body center cubic packing of spheres. The packing fraction of a body center
cubic cell is 0.68.
I’m pretty sure it would be:
NH4+Cn
Answer:
synthesis/combination
Explanation:
There are 5 main types of reactions.
combination/synthesis, decomposition, single-replacement, double-replacement, and combustion
synthesis/combination - A+B → AB
Decomposition - AB → A+B
single- replacement - A + BC → AC + B
double replacement - AB + CD → AD + CB
combustion - example - C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)
If you wanted to balance this
the answer would be →
Answer: ammonium chloride
Explanation: The reaction equation among ammonia (NH3) and hydrochloric acid (HCl) is written as follows: NH3+HCl=NH4Cl. Ammonia is a susceptible base that reacts with hydrochloric acid, forming a compound referred to as ammonium chloride.
Answer:
2.7g/cm³
Aluminum
Explanation:
Given parameters:
Mass of the cube = 72.9g
Unknown:
Density of the cube = ?
Solution:
To solve this problem, we need to find the density of the cube. The mass is given and the dimensions of the solid figure.
Now;
Density is the mass per unit volume of a substance
Density =
Volume of the cube = L³ = 3³ = 27cm³
So;
Density = = 2.7g/cm³
The body is aluminum because it has a density of 2.7g/cm³
