Answer:
A
Explanation:
because I live in a place with little water
Answer:
C
Explanation:
The molecule has 8 carbon atoms joined by 7 C-C bonds.
The first two diagrams show 6 carbon atoms, not 8.
The last two diagrams show line segments representing C-C bonds. Only choice C shows 7 such segments.
The appropriate choice is C.
0.98 g/ml the density of an object can be measured by dividing its mass
Oxygen and Hydrogen would most likely form a covalent bond that is polar, or a polar covalent bond. Due to the electronegativity difference between the 2 elements, unequal sharing of the valence electrons will occur, electrons being in closer proximity to Oxygen and farther away from Hydrogen. Resulting in the characteristic partial positive and negative charges to appear for the respective elements.
P1 = 0.75atm. P2 = ?
V1 = 150ml V2 = 500ml
T1 = 10°C T2 = 522°C
= 10+273 = 522+273
= 283K = 795K
By Gas Equation,
P1V1/T1 = P2V2/T2
0.75×150/283 = P2×500/795
P2 = 0.75×150×795/(283×500)
P2 = 0.63atm.
