Answer:
is a class of heavy military ranged weapons built to launch munitions far beyond the range and power of infantry firearms. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower.
Explanation:
it could explode
Chemical properties are mainly determined by the number of valence electrons (electrons which can be gained, lost, or shared) in the atom.
The generic reaction a + b = c, represents a synthesis or combination reaction, which is a kind of chemical reaction.
<h3>What is a synthesis reaction?</h3>
A synthesis, or combination reaction, is a kind of reaction in which two substances combine to form a bigger molecule.
The generic reaction is:
a + b = c
Some common synthesis reactions are:
- Two elements combine to form a compound.
Fe + S = FeS
- One element and one compound combine to form a compound.
O₂ + 2 SO₂ = 2 SO₃
- Two compounds combine to form another compound.
CaO + CO₂ = CaCO₃
In all the examples above, we can verify that the substances (elements or compounds) combine with each other to form another substance (product).

Ionization Trend: First ionization energy will increase left to right across a period and increase bottom to top of a family (column).
A) Sr, Be, Mg are all in column 2 of the periodic table. Based on the first ionization rule above, from increasing to decreasing energy, the order is: Be, Mg, Sr
B) Bi, Cs, Ba are all in the same row of the periodic table. Based on the first ionization rule above, from increasing to decreasing energy, the order is: Bi, Ba, Cs
C) Same rule as above. Order is: Na, Al, S
Answer: The density of 0.50 grams of gaseous carbon stored under 1.50 atm of pressure at a temperature of -20.0 °C is 0.867 g/L.
Explanation:
- d = m/V, where d is the density, m is the mass and V is the volume.
- We have the mass m = 0.50 g, so we must get the volume V.
- To get the volume of a gas, we apply the general gas law PV = nRT
P is the pressure in atm (P = 1.5 atm)
V is the volume in L (V = ??? L)
n is the number of moles in mole, n = m/Atomic mass, n = 0.50/12.0 = 0.416 mole.
R is the general gas constant (R = 0.082 L.atm/mol.K).
T is the temperature in K (T(K) = T(°C) + 273 = -20.0 + 273 = 253 K).
- Then, V = nRT/P = (0.416 mol)(0.082 L.atm/mol.K)(253 K) / (1.5 atm) = 0.576 L.
- Now, we can obtain the density; d = m/V = (0.50 g) / (0.576 L) = 0.867 g/L.
