Explanation:a b d
Explanation: i stuck at this Answer:Sometimes atoms share more than one pair of electrons, for example a double covalent bond can occur, as in the carbon dioxide molecule where carbon shares 2 pairs of electrons with each oxygen atom: O=C=O. (where = represents a double bond). Another kind of covalent bonding is called co-ordinate or dative covalent.
Answer:
45K
Explanation:
Rise in temperature = Final - initial temperature.
temperature in K = Temperature in Celsius + 273
for Celsius; T2 -T1 =45°C
for kelvin; T2+273 -(T1+273) = ?
T2+273 -T1-273 =?
T2-T1 = ?
T2-T1 =45k
hence ΔT(K) = ΔT(°C) (temperature difference in Celsius is equal to temperature difference in kelvin)
