Answer:
CaO- ionic
InAs-covalent
Al2O3-ionic
Bronze- metallic
Explanation:
CaO and Al2O3 are mostly ionic even though the posses a little covalent character but ionic bonding is the main bonding scheme. Bronze is an alloy of two metals hence it contains a metallic bond. InAs has an electro negativity difference of 0.4 between the atoms so it is a polar covalent bond.
Answer:
The volume will be 18,23 ml.
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. We convert the unit Celsius into Kelvin: 0 ° C = 273K, 44+273=317K, 17+273=290 K. The volume in L= 22/1000= 0,022L
P1xV1/T1= P2xV2/T2
V2= ((P1xV1/T1)xT2)/P2
V2=((0,905 atm x 0,022L/317K)x 290K)/0,999atm= 0,01823 L
0,01823x 1000= 18, 23 ml
