Answer:
The periodic table is also split into four blocks: s = red, p = green, d = yellow, and f = blue.
The differences in the properties of diamond and graphite is as a result of how their particles are arranged in space. This space arrangement leads to distinct crystal structures for the two compounds. In diamond, the carbon atoms are arranged in tetrahedral shape while in graphite the carbon atoms arrayed in planes.
Potassium citrate (also known as tripotassium citrate) is a potassium salt of citric acid with the molecular formula K3C6H5O7.
A good example is table salt
Table salt at room temperature is a lattice structure-- meaning its ions are SUPER close to each other and hence can't flow.
If you look at electrical insulators, it simply means they can't carry charge-- because there's no flow of charge.
If you dissolve table salt or melt it, it becomes Dissociated meaning NaCl becomes Na^+ and Cl^-
So now they are separated, and they are ions (charged particles)-- because they are separated they can flow, and because they are charged, they carry a charge. Hence, a flowing charge when they are melted (at super high temperatures) or dissolved (yes, even at room temperatures)
Answer: 43.2 grams
Explanation:
Given that,
Amount of moles of NH4 (n) = 2.4
Mass of NH4 in grams (m) = ?
For molar mass of NH4, use the molar masses of:
Nitrogen, N = 14g;
Hydrogen, H = 1g
NH4 = 14g + (1g x 4)
= 14g + 4g
= 18g/mol
Since, amount of moles = mass in grams / molar mass
2.4 mole = m / 18g/mol
m = 2.4 mole x 18g/mol
m = 43.2g
Thus, there are 43.2 grams in 2.4 moles of NH4.
