Answer:
The new pressure of the gas is 57.69atm
Explanation:
P1 = 50 atm
T1 = 390K
T2 = 450K
P2 = ?
This problem requires pressure law.
Pressure law states that the pressure of a fixed mass of gas is directly proportional to its temperature provided volume remains constant.
Mathematically,
P = kT, k = P / T
P1 / T1 = P2 / T2 = P3 / T3 .......Pn /Tn
P1 / T1 = P2 / T2
Solve for P2,
P2 = (P1 * T2) / T1
P2 = (50 * 450) / 390
P2 = 57.69atm
The new pressure of the gas is 57.69atm
Explanation:
A synthesis reaction: It is defined as a kind of reaction where one and more than one reactant attached and creates an individual product.
The formation of the water is an example of a synthesis reaction because here more than one reactants combine and create a single product (water). Water formation occurs when 2 hydrogens and an oxygen share electrons through covalent bonds.
2H + O ----> H2O.
The theory assumes that particles don't experience intermolecular forces. Thats right answer
Chlorine.
You can work this out by counting along the periodic table in rows. Chlorine falls as the 5th element in the 3rd down row of the p block (left hand side) of the periodic table.
Answer:
The density of B is 11/14 = 0.79 g/cm³
It will float in water
